Question about Sony KP-46WT510 46" Rear Projection HDTV

Problem with picture and sound

When I turn the TV on, the screen appears green with horizontal curved lines and shuts off after approximately 10 seconds.  There is no sound, no picture.  A tech came out and replaced the three crt's?  I think that's what they are called.  When he turned the set back on, the same green screen appeared with the horizontal curved lines.  He was able to make the screen turn different colors, but the curved lines and no picture were still there with no sound.  The set is under warranty and I am getting a replacement. But if I can keep this set,  what do you think it needs get it going?  Any help would be appreciated.  Thanks.

Lines down screen

We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

TV turns on with a green screen with curved horizontal lines.

It seems you may have a serious problem with your video board. That's why you are getting those symptoms. It's better if you replace it asap!

Red and blue 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

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.


I hope this helps,


Thank you,

Curved horizontal lines in picture

Its Sounds like Convergence Circuit,If you take the Back off and look on the right side you should see a Board with Big black Ics Mounted beside a Large Heatsink,Mark the wires where they go and Make sure the POWER is Off Pull the Board out and Inspect the Connections from the ICS,you find Circle Breaks,They need to Be resoldered and That should fix the Set....

Green screen with almost horizontal zigzag lines

Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
