Signal Problem


Hi,

When the sound is working and the picture is not it indicates the main power supplies are working but the picture supply is not. The picture supply that powers the projection tubes is a high voltage generator and is very expensive to repair. Not even most tv techs now how to troubleshoot them. So, I cannot recommend you repair it yourself unless you are a trained high voltage tech.

The cost of repair - my wild guess - would be around $300. However, the real cost can only be determined by someone who can make an accurate diagnosis - which will require a hands-on approach the problem.

If you have any other problem please ask me..
Goodluck,

Green bulb-or lamp on ultravision hitachi 57uwx20b does not work how much to replace?


On a projection television you will have to replace all three(red,blue,green) projection guns in a matched set, the reason is if you replace just the green gun, your picture will be over saturated with green light making your picture look green,because the new gun will be alot brighter than the red and blue guns.
With that said, repair will cost approx.$400+, I've heard up to$600. Good luck !

I have a hitachi 57uwx20b that had distorted


If the problem "distorted picture" was red and blue lines everywhere you may have a shorted convergence IC and the set may be in shutdown; someone needs to determine by unsoldering the two convergence IC chips and then trying to turn the set on; if they are unsoldered and the set comes on---one of them is the trouble----also you can look around them at a number of small resistors to see if any are discolored or look burnt--If you need more direct assistance my email address is:

etower.766@netzero.net

The convergence ic chips are usually located on the right side of the set as you look at it from the back on a large finned piece of metal(it is a heat sink to keep them cool).

Hitachi, model 57UWX20B ghosting?


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hitachi 57uwx20b


First of all there is no light engine inside your set. Your model is CRT based. Can you better describe what you mean by the green only working occasionally? What exactly is the picture doing? Also, please confirm that your model is: 57UWX20B.

Thanks,
Dan

Magnavox model 6P5440


You can turn up the Screen controls in back of set. Look for the focus block that has 6 controls on it. 3 are for the screen and 3 for the focus, in each color Red, Blue, Green. need to turn evenly to keep color balanced. On set turn color all the way down and then get a good black and white picture.
