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.

My sony tv stars blinking 5 times in a row, then the picture goes black for a second comes back then goes black again and it keeps doing it non stop

tv has a blanking picture mute circuit. adjust the screen controls which are located behind the speaker grill in front of set. there will be a access panel to unscrew in center and then you will see a black 4 inch square box with 6 physical knobs. 3 control screen the other 3 controls focus for red, green, blue. turn them down and slowly start turning them up. fixed.

I had this problem and at the same time I was getting blue tint. When the blue got darker, this would happen, Adjusted the voltage on the guns (3 screws in the front - lower panel off) and the blue went away and it stopped turning off. But later, it would start all over again. Same procedure, same fix.
