I have this Exact same TV and I had the exact same problem that you are having now! you will need to get the FLYBACK UNIT replaced on the D CIRCUT BOARD ! It solved my problem and I am sure it will fix yours! (this is a common problem with this model!) the part is around $70.00 but a pro will have to do the repair!

I know this isnt what you want to hear but your best solution is to call a repairman in.if you dont know anything about tvs and ask people on here they will have you so confused and have you spending moey you wont need to be spending on parts you dont need.if it were my tv i would call in a repairman and let him fix it right the first time so you dont have to do alot of running around looking for parts you may or may not need.

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.
