SONY KP51WS500 bought Feb. 2003 from Circut City

The other day the tv started to flash every once in a while. LAter that night the picture would go out completely and then a few seconds later the tv would shut off and the light would blink 5 times. The next day it worked fine until that night. Then the screen went red and would fade until it turned off. I called SOny and they said it is a power probelm . We live in Japan and don't speak th elanguae so a repairman would be hard to come by. ANy suggestions for what we might do? Alyson

Possible clod solder connection in the scan b+ voltages,contact sony and get them to check their dealer store locations in your area and have them send a message to the dealer describing your fault to them also.

I have a Sony, 54" Projection Screen HDTV that I bought in 2002. I believe it is a 1080i. When I am waatching TV, I notice that when the screen is mostly black, for instance a night scene, the black areas...

Confirm the actual model number as the one indicated in the title is not HD.

Some of these sets had bad picture tubes that on a black screen or blank video input may in your case show faint curved lines and or some color (red,green or blue) present in the background.

If this is the case there is a fairly simple way to attempt to adjust something for this--not in the customer menu but fairly easy to get at and try.

Most of these sets were KP51ws500, 57500 etc.

When I power up, 5 seconds later this back projector TV turns itself off

t does sound like a bulb problem, either its over heating and shutting off to protect itself, or its already shot. Give a TV repair shop a call and see if they can give you an approximate price, then decide to ditch or repair it.

Picture problem

Lloyd, convergence IC`s have failed, usually STK392-110`s mounted on large aluminum heat sink with the above number stamped on the front, also look for any slightly burnt resistors located in front of the IC`s, not an easy fix for the average joe, you`ll need a good knowledge of soldering and an accurate volt meter to measure the resistors, any questions? e-mail me, BMW Rider
