My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


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.

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


Increase the current flow to the blue color gun. If it is not adjustable it will need replaced and this is a major repair. You can try to reduce the red and green guns and increase the output transformer for a temporary fix, but save up your pennies for a replacement. Have a tech look at it before running out for a replacement because the SONY is the better model projection televisions.

Sony 46" RPT color problems


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,
Shuttle83
