Question about Sony KP-51WS500 51" Rear Projection Television
I bought this TV back in August 2002……………..you guessed it the extended warranty has expired.
In the Past I’ve had the Curved RED Lines in the screen and had fixed them adjusting the controls for the re-trace (Red, Green and Blue) the controls on the front (behind the wood Panel).
The problem I’m seeing now is that the Pictures Brightness starts to flicker once the TV has been on for awhile.
It?s like the power to the Projector is fluctuating causing the brightness to flick.
Anyone have any suggestion before I call a Service Guy?
1) Over-riding a common convergence problem by turning up
the screen controls on the focus block is not the right approach.
Brightness fluctuation can result......
2) Change out STK392-560 IC's ( convergence) and
3) Reset RGB screen controls to normal level
Let me know how you are doing.....T.

Could be one or more of three things.
1.could be the crt itself.(sony had a bad bunch of crts for this model)
2.could be the vertical ic on crt board.
3.could be the focus block
in my experience solutions 2 and 3 are more common....
