No picture, no sound, indicator light on then goes into flashing

Hi,
I think your Display card not proper work so please contact LG Technician.

Thanks.

The fault is with its main board itself. Troubleshooting to this board is not an easy work to a user can do. It will be best to contact any service technician. google.com/+GopakumarGopalan

Have you activated the self check this set has that will indicate what error was picked up?

Sounds like your color wheel has gone bad.

You may want to change the lamp. It may be on the edge of failing totally.
Hope this helps,

sounds like swollen capacitors to me see what i mean here


Samsung LCD TV Failed Power On Clicking Repair

The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

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.

I had the same problem and my local repair guy soldered a defective sensor so that it goes around that problem. I also had to buy a new bulb. Now my picture is "cloudy" and the repairman has no idea why. I am waiting for them to call back on it.

same problem. TV turns on but no picture or sound. when i press power button on the remote control orange light flashes for about a minute and goes back to red.
TV won't turn on. It iz frustating me a lot ay !

How many times does the light flash, as there is a code that can give an indication as to what circuit is bad.
