The vertical scan amplifiers are loosing gain. This is usually caused by aging capacitors, and sometimes other types of components.

Because of the age of the set, it is possible that after servicing the fault the chance of having other component failures is high.

Sony KP-51WS500: This TV comes on for a few seconds of picture and sound. Then the picture fades to green and then turns off within another 10 seconds. Is this a power supply problem? Or should I look in...


Adjust the Green screen drive,turn it down and see if that corrects the problem.
Remove the Front Bottom Panel on front of Tv and behind it will be the Screen/Focus Control block
It will have 3 controls on Top for Focus to each Tube R/G/B
and under them are the Screen drive controls for R/G/B.
But if adjusting the Green Screen Drive Control does not Fiox It ,then you have a Bad Green Tube.

DOUBLE IMAGE ON SCREEN. tOP OF PICTURE LOOK LIKE A


That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
Thanks.

I have a sony kp-41t65 tv acting like computer screen out of whac


Projection sets have two very common problems outlined below.

The first common problem is convergence

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. The TV can also shut down when the convergence starts to fail.

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,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.

You can get more information and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Kp-51ws510 picture issues


Bob, remove the front speaker panel and you will see a small access panel remove that also and you will see a small block with 6 dials on it. three on top and three on the bottom. Look closely at the dials and you will see focus for 3 of the dials and Screen for the other 3. The dials marked screen control the drive amount for each tube and are laid out like the tubes green dial in the middle and blue dial on the same side as the blue tube. try turning the blue tube down a little. If that deosnt help you will no doubt need a new blue tube, which is a fairly common problem with that model Sony. If you require more assistance please let me know.

I would suggest to turn the screen control potentiometer down a bit, this control is found on the front of your TV nearby the CRTs.
The part looks similar to the picture. Click here to see picture.
The red control is the one on the left if you are facing it.
Let me know if you need further assistance.

Color splotch when TV is powered on, then TV powers down automatically


Good Day;
It is very common for this model from what you spoke. If you handy return to me, Big Irish, and I will continue to help you.

99.9 % of the time of what you stated it sounds like a shorted CRT, picture tube. I have seen hundreds.
First, call the manufacture and complain about your concern and ask them for a CONCESSION because your tube has gone out.
2.If that does not work ; call a factory authorized service dealer to confirm problem and get an estimate, then return ti #1.
Good Luck, Day, Big Irish. I hope I helped.
