My sony projection tv model # kp-46wt500 has a green and red tint. how can i fix it?

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.

convergence problem expect to pay around $300

Replace Both of your convergence ICs STK392-??? they are big black ICs will have part number on them also CK pico fuses they look like resistors but are fuses they will be yellow or green will be around ICs.

visit your local service center. you cant do anything more up to this point

Green and Red guns seems defective and requires replacement.
Both guns (CRTs) are no longer available so TV has no worth to repair.

all three guns red blue and green should be replaced and the flote.
cost could be from $400 to 680 in parts depending on wer you buy them. I would but the parts my self then pay the repairmen to do the install this way you dont get priced up to high in parts cost.

Take a look at my post on Convergence IC replacement..Thank you GURU JAY

You have a pair of Bad STK392-560. replacing these will definitely fix the set.

Some people have a scale on their T.V. somewhere, or for most cable users it shows on the menu an area where you can change contrast, color, tint, brightness, ect...

Hello BlueKalel,

It looks like your green CRT is malfunctioning. You should try to see if the voltages are correct on the socket of the green CRT and check the high voltage on the green CRT using a high voltage probe. Use a schematic diagram to reference these voltages to.

I am positive that the problem is the green CRT or the circuitry leading to the green CRT. Please use caution when checking these voltages.

Thank you,
