It sounds like the power supply is bad.Open the back of the TV,and look at the can shaped items called capacitors on the circuit boards.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.I hope this helps.If you have any questions,please let me know.Thank You very much!

    The TV is currently in the repair shop. The technician said it is a TCON board and that Sony does not offer the Board separate, therefore $1500 bucks. He seems stand up, but when I search for TCON it never seems to be my problem.

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.

Tv picture and sound comes on and off


You probably have a bad lamp sony part number A-1085-447-A XL2200 if your model number is KDF-55WF655. I recommend using original from sony 199.99 retail.

TV Picture Goes Black


I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
