Your backlight controller is faulty and needs to be repaired or replaced. If you shine a torch lose to the screen you should be able to see a dim picture.

    There might be loose physical connection. Better check the cables connected to your tv and make sure everything is plugged in tight.

SOURCE: TV turn on and off

Your TV has a power problem, it maybe high or low supply voltage that causes the TV to turn it self off because of an error. A technician from the manufacturer knows what error it has just by looking at the flashing standby light. Best is to take it to an authorize service center for repair... ^_^

SOURCE: Tv Turn sound on, No Picture, turns itself off within seconds

The TV is trying to go on protect mode because an internal fault had been detected. For that reson the protection circuit keeps turning off TV continuously.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

SOURCE: TV Turns on picture comes on for 30 seconds then

This is not the fix for this TV. I guarantee that none of the capacitors exhibit the common bulging characteristics of a faulty capacitor. The common answers to everyone's questions are to replace the capacitors. Most likely the culprit is the inverter board.

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.
