How many times does it blink? if it is blinking 4 times like I think it is... it is a problem with one of the fans (there are 4) in your TV.. It is a simple fix... try using an air canister to clean them. It will require some disassembly though.

Red/green lights both blink and tv will on turn on

Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

Sony LCD KF-50WE610 no picture-red light blinking

3 times standby red light blinking shows that lamp cover has not been placed back properly after lamp replacement.
Make sure lamp cover, (the first thing that you removed to replace lamp in tv) is fixed securely then turn tv On.

Tv won't turn on. It blinks green then red.

Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?

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.

Picture & sound go on & off every sec, red light blinks 5 times

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Power problem

How many blinks is it doing? It has a built in self diagnosis code that it will blink. Pause a second then blink again. Count the blinks then let me know.
