SOURCE: TV does not turn on; red light blinking.

your problem is a more technical problem you will need a tech to look at your set if you are not a tech you wont be able to do it your self. contact a tech to repair your set the problem is in the power supply or related circuit.good luck.

SOURCE: Won't turn on or off - red light blinking

This sounds like a power supply problem, visually check the fuses and if they look ok, and you have a backgroud in electronics test to see if the set is prducing Dc voltage, you will need a multimeter and a schematic to do this with. However, if you do not have a background in electronics please take the set to a qualifide TV repair shop to have the repairs done.

I hope this helps.

Thank you,

The TV is on protect mode.

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

If you want to repair at your own expenses, just locate any good qualified repairer.
