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.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.
