Ur tv have a problem known as convergence problems.Ur tv convergence board must have it 2 STK convergence ICS and some or all it resistors to be replaced to solved convergencce problems.The shop will cost u $300-350 for parts and labors.
It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen. Do you see standby red light blinking when TV shuts off after showing blue image for a while? If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution. Thanks.
if you take the front cover off the tv, you will see 6 little nobe, the top 3 are focus, bottom 3 are brightness, should be RED-BLUE-GREEN in order from left to right, find the one that is blue, turn it down a quarter turn, should fix the problem
your convergence IC;s are out, they cost about $40, if you know how to solder, you can do it your self, if not , I would try to find somone that can, service centers charge about 4 or 5 hundred, after you get the new ones, there easy to find on the board in the back of the tv
blown fues on the G board, that should fix my problem and or might need to replace stk392 convergance amp ic's ·http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm ·http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
Your blue crt has a short - you can verify this by unplugging the socket from the blue crt and powering up the set and you should see a yellowish looking picture with just the red and green crt's operating. You can try turning down the screen control pot (B) for blue with the blue crt on (just to the point where you no longer see retrace lines in the picture on a blank input)Sony has had a lot of problems with the crt's on these models and sooner or later all the crt's will fail - For a permanent repair all must be changed.
