The disadvantage of CRT, nonetheless is the dimension, weight and power usage. The focus has now shifted to flat panels. Canon and Toshiba are about to introduce a new show technologies recognized as SED or Surface-conduction Electron-emitter Show.

The SED is made up of layers of glass plates seperated by a vacuum. one plate is mounted with electron emitters, a lot like the electron gun in the CRT. The number of emitters are equal to the number of pixels. An additional layer, is coated with a flourescent substance that reflects light at different wavelength, than the incident light.

When a voltage is used, electrons are emitted from one aspect of a very narrow slit, and are scattered and accelerated by voltage used on the other aspect of the slit, causing collision with the flourescent coated plated and light is emitted. To the trained eye, a visible lag can be observed when viewing LCD’s.

SED is similiar to CRT with the light emission idea, and the producers declare the dynamic colour can be expressed in sharp pictures and quicker responses than LCD’s or plasmas. Because no deflection of beam is required, screens of more than 40 inches and only centimetres thick can be created. Power usage is claimed to be one 3rd that of PDP and LCD’s.

The introductory cost, at this stage may be of some problem, nonetheless as with all new technologies, it can be predicted to decrease as enhancements are made. We maintain on the lookout.

Rob Foster from the UK sent me a port PCI USB card since he had a few extras. Thanks again, Rob. When installing hardware or devices, most situations require loading the software FIRST before doing anything else. This one didn’t – so be sure to check this out before attempting to put the card in. Before starting the process, be sure you have an open PCI slot, a standard slot that has one big connector with a small one behind it.

Turn off the computer, if it is not already. Take off the CPU case. How this is done depends on the CPU. If you lost or misplaced the manual, I’m sure your computer manufacturer has info online. Google it, if needed. Slide the PCI card into the open PCI slot.

At this point, you can cover up the CPU, but some people leave it off until turning on the computer and checking all is OK. When turning on this little feller, it found the new card right away and worked. I didn’t even have to run the software. The card came with four USB ports, one of which holds the backup system. It took under two hours to back up the computer (get size), faster and easier than the tape back up.

Well, it only took a year or so to get around to adding the USB 2.0 ports as that’s about how long the back up system has been sitting here taunting me.

RAID disk repair, as you may expect is quite a complicated process. But the good thing going for it is the chances for retrieving lost data is higher than with most other types of disks because the typical RAID architecture strategically distributes data randomly across the array. What this sort of architecture demands of recovery professionals is to specialize in the diskâ??s many different levels.

In a nutshell, these are all the levels that the RAID disk recovery team is up against. RAID 0, 1, 0+1; RAID 3, 4; RAID 5; RAID 10; Hardware RAID including: AMI, Compaq, Dell, Adaptec, IBM, etc.; and, Software RAID including Mac OS; Windows Servers including 2K, XP, NT; Linux, Solaris, Novell, etc.

Just some RAID systems that most RAID disk recovery specialists should all be familiar with are: Quantum Snap Server; Maxtor MaxAttach; Adaptec AAA131; Compaq; Dell Perc Systems; IBM; AMI; Mylex; and yes, many others!

The two most common implementations of the RAID architecture are Levels 4 and 5. Level 4 provides block stripping with a parity check. When a data disk fails, the parity data is used to create a replacement disk. Level 5 provides data stripping at the byte level and also stripe error correction information, which results in excellent performance and good fault tolerance. These two types are certainly the best friends of the RAID disk recovery expert as these are the easiest to restore when the situation arises.

I often sit up late viewing DVDs on my laptop computer pc subsequent a difficult operating day.

If you are interested in Desktop pc methods, then the DVD generate will permit you to view your preferred DVDs on your preserve track of. I presently have a 21-inch preserve track of and a 5.one pc surround kit. This offers DVDs to existence and functions just like a house cinema system, nonetheless the greater higher quality is even a lot better.

Most DVD ROMs will come in speeds ranging from four to 10 tempo. This is much more than adequate to view the newest DVDs, play the newest video clip clip video games, and use and set up the newest software system system. Normal CDs can only have out at a certain tempo, and it is a fantastic offer decrease than what the DVD ROM offers. I hope you have a a lot better knowing of why DVD ROMs are now used much more than a regular CD these days. It is basically all component of bringing a house satisfaction system at the greatest greater higher quality nearer to everybody.

There are nine common problems can be found in a flyback transformer:

a) A shorted turned in the primary winding.

b) An open or shorted internal capacitor in secondary section.

c) Flyback Transformer becomes bulged or cracked.

d) External arcing to ground.

e) Internal arcing between windings.

f) Shorted internal high voltage diode in secondary winding.

g) Breakdown in focus / screen voltage divider causing blur display.

h) Flyback Transformer breakdown at full operating voltage (breakdown when under load).

i) Short circuit between primary and secondary winding.

Testing flyback transformer will be base on (a) and (b) since problem (c) is visible while problem (d) and (e) can be detected by hearing the arcing sound generated by the flyback transformer. Problem (f) can be checked with multimeter set to the highest range measured from anode to ABL pin while (g) can be solved by adding a new monitor blur buster (For 14′ & 15′ monitor only.) Problem (h) can only be tested by substituting a known good similar Flyback Transformer. Different monitor have different type of flyback transformer design. Problem (i) can be checked using an ohm meter measuring between primary and secondary winding. A shorted turned or open in secondary winding is very uncommon.

What type of symptoms will appear if there is a shorted turned in primary winding?

a) No display (No high voltage).

b) Power blink.

c) B+ voltage drop.

d) Horizontal output transistor will get very hot and later become shorted.

e) Along B+ line components will spoilt. Example:- secondary diode UF5404 and B+ FET IRF630.

f) Sometimes it will cause the power section to blow.

What type of symptoms will appear if a capacitor is open or shorted in a flyback transformer?

Capacitor shorted

a. No display (No high voltage).

b. B+ voltage drop.

c. Secondary diode (UF5404) will burned or shorted.

d. Horizontal output transistor will get shorted.

e. Power blink.

f. Sometimes power section will blow, for example: Raffles 15 inch monitor.

g. Power section shut down for example: Compaq V55, Samtron 4bi monitor.

h. Sometimes the automatic brightness limiter (ABL) circuitry components will get burned.

This circuit is usually located beside the flyback transformer. For example: LG520si

Capacitor open

a. High voltage shut down.

b. Monitor will have ‘tic – tic’ sound. Sometimes the capacitor may measure O.K. but break down when under full operating voltage.

c. Horizontal output transistor will blow in a few hours or days after you have replaced it.

d. Sometimes it will cause intermittent “no display”.

e. Distorted display i.e., the display will go in and out.

f. It will cause horizontal output transistor to become shorted and blow the power section.

How to check if a primary winding is good or bad in a Flyback Transformer?

a) By using a flyback/LOPT tester, this instrument identifies faults in primary winding by doing a ‘ring’ test.

b) It can test the winding even with only one shorted turned.

c) This meter is handy and easy to use.

d) Just simply connect the probe to primary winding.

e) The readout is a clear ‘bar graph’ display which show you if the flyback transformer primary winding is good or shorted.

f) The LOPT Tester also can be used to check the CRT YOKE coil, B+ coil and switch mode power transformer winding.

NOTE: Measuring the resistance winding of a flyback transformer, yoke coil, B+ coil and SMPS winding using a multimeter can MISLEAD a technician into believing that a shorted winding is good. This can waste his precious time and time is money.

How to diagnose if the internal capacitor is open or shorted? By using a normal analog multimeter and a digital capacitance meter. A good capacitor have the range from 1.5 nanofarad to 3 nanofarad.*

1) First set your multimeter to X10K range.

2) Place your probe to anode and cold ground.

3) You must remove the anode cap in order to get a precise reading.

4) Cold ground means the monitor chassis ground.

5) If the needle of the multimeter shows a low ohms reading, this mean the internal capacitor is shorted.

6) If the needle does not move at all, this doesn’t mean that the capacitor is O.K.

7) You have to confirm this by using a digital capacitance meter which you can easily get one from local distributor.

If the reading from the digital capacitance meter shows 2.7nf, this mean the capacitor is within range (O.K.).

9) And if the reading showed 0.3nf, this mean the capacitor is open.

10) You have three options if the capacitor is open or shorted.

- Install a new flyback transformer or

- Send the flyback transformer for refurbishing or

- Send the monitor back to customers after spending many hours and much effort on it.

* However certain monitors may have the value of 4.5nf, 6nf and 7.2nf. Note: Sometimes the internal capacitor pin is connected to circuits (feedback) instead of ground.

Tv rca flyback transformer circuits usually do not have a internal capacitor in it.

If you have a flyback diagram and circuits which you can get it from the net, that would be an advantage to easily understand how to check them.

Have you ever wandered around a huge Art Gallery and marvelled at the works by Tintoretto, Raphael, Constable or any master painter who has produced huge canvasses? Then again, we have many fine examples of beautiful artwork in cameos and miniatures. In fact, in all sizes between these two extremes the evidence of creative genius can be found down through the ages.

However, it’s patently obvious that the correlation between size and creative genius is poor. Mere size on the premise, "never mind the quality feel the width" is not the prime element of a masterpiece. Yes we are fascinated by the Sistine Chapel, for example, by the sheer scale of the paintings, but it’s the genius of the painter that draws the eye. It’s also true though that the artist tugs at our heartstrings by the wealth of detail that working in a large format permits.

In the same way, large format and medium format cameras have traditionally been the working tools of professional photographers for many, many years. In a previous article, I suggested that there would always be room for film, especially for users of the larger formats.

Now, we get to the nub of the matter, because in digital parlance, the wealth of detail evident in the larger formats is expressed as the size of the file. Unlike physical dimensions which cannot be changed once the work has been committed to the recording medium, be it film or indeed canvas size, the digital file is not so restricted.

Of course, when image size is changed from the original during, say, image compression, there is generally a loss in quality e.g. jpeg Even the use of a lossless transformation doesn’t add anything to the image, it merely preserves what’s there.

However, there is a revolutionary item of image manipulation software that does totally "change the picture" It comes as a Photoshop plug-in with Photoshop 6.0 or higher and it’s called "Genuine Fractals" and here is what the originators claim,

"It’s an indispensable tool for photographers, graphic artists and digital imaging professionals, Genuine Fractals enables you to create resolution-independent images from any size file and lets you print superior quality enlargements without any degradation in image quality"

By saving your digital image with this package as a very small stn file, you can create lossless files of up to 70Mb and beyond. After saving and re-opening this file in Photoshop, Genuine Fractal kicks in and you can easily produce files of a specified size

I was stunned by this software and began to wonder what the impact might be for both digital photographers and medium/large format professionals. Of course, as already stated, this increased size does NOT put extra information into the shot. There again, neither does making a 67 dupe of a 35mm slide improve image quality and many photographers still do that when submitting to libraries.

Digital photographers may get even more benefits by beefing up the file size using Genuine Fractals, before printing out enlargements. This could be very useful for Wedding Photographers who want the convenience of using a digital camera, but are unhappy about the quality of enlargements often requested. Using Genuine Fractals may save time effort and money by eliminating the need for a film backup camera.

On the other hand, it may be that Genuine Fractals may produce the best result with photos captured from film and then scanned, because noise in the original image is not removed when enlarged, in fact it will be more obvious. This means that mid-range digital camera shots are likely to fare worse on enlargment than film shots captured with 10 million pixels+

With a new version Genuine Fractals 3.5 just released, it could be worth a test and could be a worthwhile investment too. So, if you want to explore this a little more, get a copy of Amateur Photographer for 23 October 2004 and read their review of this exciting software.

You can get a free test copy of the software itself from this link: http://www.dcp-systems.co.uk

Why bother with a medium format camera if 35mm caressed by this Software will do instead? Oh I know I’ll get lectures from purists for even suggesting something so daft, given superior lenses and better optics, but for some people that may be just overkill. If this article has opened up the possibility of a better working method for some freelances, that’s all that matters.

So don’t please run around telling your mates that size does not matter and that I’ve assigned medium format cameras to the dustbin of history. No, I’m just shining the spotlight on that funny old coin digital/film and giving it a flick in the air. Who knows how it will land? At least I’ve got a 50-50 chance of being right!

HP DeskJets and BubbleJets are popular examples of printers that use this technology.

Epson printers work on the same principal with the exception of a minor twist ? they use a transducer to produce the droplets in what is referred to as piezoelectric DOD.

So what about the ink ? does it matter what kind you buy as a replacement?

The answer is yes, it does matter.

The ingredients that go into ink play a huge role in the quality of your printouts. All ink manufactures work to strike the delicate balance between print quality, time it takes to dry, and nozzle performance. As you might have guessed, as the print quality improves, the dry time increases.

Manufacturers have to be careful that the ink does not dry too quickly ? there is the danger that it will actually dry on the nozzle. This can ruin your print head, definitely clogging up your nozzle, and reducing the print quality.

DVDs are produced from a .six mm thick disc of polycarbonate plastic coated with a much thinner (reflective) aluminium layer. Two such discs are glued collectively to type a 1.two mm double-sided disc. The fundamental DVD disc is thinner than a CD to make it possible to use a lens with a higher numerical aperture.

A single-layer DVD can store four.seven Gbyte, which is about seven occasions more than a standard CD-ROM. By using a research laser at 650 nm (was 780 nm) wavelength and a numerical aperture of .six (was .45), the research-out resolution is elevated by a component 1.65. This retains for two dimensions, so that the actual physical information density increases by a component of 3.five. DVD utilizes a more efficient coding technique in the physical layer. CD’s error correction, CIRC, is altered by a powerful Reed-Solomon item code, RS-Computer 8-to-Fourteen Modulation (EFM) is altered by a more efficient edition, EFMPlus, which has the exact same characteristics as traditional EFM. The CD subcode is removed. As a outcome, the DVD format is 47% percent more efficient with respect to CD-ROM, which utilizes a ‘third’ error correction layer.

DVD Media can include:
DVD-ROM (research only, produced by a press)
DVD-R/RW (R=Recordable as quickly as, RW = ReWritable)
DVD-RAM (random access rewritable after-write checking of information integrity is always energetic.)
DVD+R/RW (R=Recordable as quickly as, RW = ReWritable)

Two DVDs with different bottom sides.The disc may have 1 or two sides, and 1 or two layers of information per aspect the quantity of sides and layers determines the disc capacity.

DVD-five: single sided, single layer, four,704,317,440 bytes, four.seven gigabytes (GB), or four.38 gibibytes (GiB)

DVD-9: single sided, double layer, 8.five GB (seven.92 GiB)

DVD-ten: double sided, single layer on each sides, 9.four GB (8.75 GiB)

DVD-14: double sided, double layer on 1 aspect, single layer on other, 13.3 GB (twelve.3 GiB)

DVD-18: double sided, double layer on each sides, 17.1 GB (fifteen.9 GiB)

The capacity of a DVD-ROM can be visually established by noting the quantity of information sides, and looking at the information aspect(s) of the disc. Double-layered sides are usually gold-coloured, whilst single-layered sides are silver-coloured, like a CD. One additional way to inform if a DVD consists of 1 or two layers is to look at the middle ring on the underside of the disc. If there are two barcodes, it is a dual layer disc. If there is 1 barcode, there is only 1 layer.

Each and every medium can include any of the above content material and can be any layer type. Double layer DVD+R discs are currently on the market.

The format was created for higher definition video clip, as well as storing large quantities of data. A single layer Blu ray disc can maintain 25gb of data, which is the equivalent to over two hrs of higher definition tv or much more than thirteen hrs of regular definition tv. There are also twin layer versions of Blu ray that can maintain up to 50Gb of data.

While current optical media utilizes a red laser to study and produce data, the new format utilizes a blue-violet laser rather. Irrespective of the various kind of lasers utilizes, Blu ray drives can be created backwards compatible.

The advantage of utilizing a blue laser is that blue light has a shorter wavelength so that it can be centered on a smaller sized sized target region than a red light laser. This permits data to be packed in much more densely permitting much more area for data in the precise same sized bodily area.

Blu ray is known as Blu ray simply because it utilizes a blue light laser to produce data onto the disc.

Blu ray is predicted to alter VCRs and DVD gamers and recorders over the coming many years simply because Blu ray provides so a great deal much more ability. Even though it will think about time for Blu ray technologies to be arrive broad spread simply because the price of DVD drives and media is so a great deal less expensive than Blu ray at this time.

Chuck Red runs several web sites such as http://blueraystore.co.uk and http://blueray-media.co.uk

Enter TheHonestCompany.com, a website where its founder posts his experiences with internet fraud and his motives for fighting back against a corrupt web right on their home page. A trip to this companies ‘about us’ page serves to quickly establish their position as the anti-fraud internet company, numbering abusive tactics used by hoaxsters and detailing their humble beginnings from an LA area backyard garage to a B2B powerhouse that now offers almost 100,000 computer related items from a network of 23 distribution centers nationwide.

This may someday be ‘made for the movies’ stuff if it’s true. Move over Microsoft, Apple, and HP ? here’s what could (hopefully) be the beginning of another rags to riches story with an ‘honest’ plot twist! An honest reseller bashes Internet scammers, preferring to do business the hard way ? the honest way. Are we dreaming? Could this be real? Could the days when ‘The Customer is King’ be making a comeback in of all places, the web?

TheHonestCompany.com expects to earn a significant portion of the home and SMB computing technology markets web-based sales over the next few years.

"Top-tier technology resellers like CDW and CompUSA will not bother us as we will not impact them. They have decent reputations, loyal customers, and higher prices. It’s the second-tier, priced-based 90% of their smaller competitors that we are fighting," says the founder of TheHonestCompany.com, David Johnston, "Those guys have corrupted the Internet and seriously hurt honest companies like ours. Every-time some scam web company rips off a customer, somewhere else a real person at a real company gets hurt too. By using honesty as a weapon, we intend bring the web consumer something they are starving for by making the web a better place to shop ? it’s a dirty job that no other company was willing to be the first to start doing."

According to David, Internet technology consumers have no idea of the great extent that fraud permeates the web. He says that if every web consumer knew what he knew about the extent of internet fraud, they’d pick one or two honest, technology web sales companies to do business with and lay low for awhile, because he says he’s got some serious mud to start slinging as his company gears up for an upcoming advertising and marketing blitz. "There’s a massive pack of internet companies pretending to be real when they are not. Most other legitimate web companies have been acting rather sheepish. I intend to kill wolves by exposing them as what they really are to the Internet public."

David is a man on a mission, passionate and articulate in his vision of his companies place on the web and their future. He leaves no doubt about this as he summarizes his company’s identity.

"TheHonestCompany.com is transforming the web purchasing experience by providing web shoppers with a trusted, reliable source of technology products along with prices far below those of most traditionally recognized web retailers. With a staff of top-notch industry professionals at its core, offering prompt and full service to each and every customer, The Company encourages phone calls from any customer with questions or comments before, during, and after a purchase. TheHonestCompany.com does not outsource, does not spam, and does not sell or share its customer’s personal information. The company operates as a safe-haven for the price conscious customer leery of unbelievable prices from no-name websites, restoring confidence in buying over the web. This is business done right." Bravo, David. Honestly, it’s about time!

Derek Kadonaga has worked in the retail technology industry for over 10 years, first as an executive with CompUSA. In the past several years he has applied his industry knowledge to helping technology start-ups.
