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

substituion = can get expensive.................T.

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,
