Sounds like the power supply. A lot of these TVs use power supplies with cheap capacitors. When the go bad or get weak the backlight will stop working. You will need to either replace the power supply or if you know someone skilled with a soldering iron and electronics, trace down the bad capacitors and replace them.

Brown screen


Try unplugging your television for a minute and then re-plug and allow it to reboot. After re-start, you will need to access the menu to re-scan for channels.

Hope this helps!

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.

Sound stays on & picture goes to blank screen


I do not see any reference on this problem and I even checked with Sony. If you are on a cable box, I suspect that is the problem.
