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.

Blinking powerlight on front when i try to turn on tv


This is more likely a power supply failure. Most causes of tv failure are due to bad capacitors on either a system board or the power supply. In this case, it sounds like the power supply. You can test the capacitors with a capacitor tester to determine faulty capacitor. You can also test other components like power supply current with voltmeter or mulit-tester.

No picture on TV with powerlight on


If you press the power button *on* your TV (rather than using the RC), does the power light still stay on red rather than turn green?

No picture, sound OK...setup menu shows up, able to get picture in PIP


You will need to check the inputs on the television. You more than likely have a bad video in signal. This can be a bad cable or a loose connection either at the input of your television or at the output from your receiver, (cable or satellite). First, try wiggling the cable and then try replacing it. This should fix the problem. If not, your signal may be routed through a stereo or other switching device?
