Hi!

Sounds like you have a bad power supply board! This is not hard to do yourself, as long as you are somewhat handy! Take the case apart (back side), and look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain).

If you see this problem, you can buy a new power supply at www.shopjimmy.com or ebay. You will need the make and model, of your tv to order! Good luck, I hope this is helpful!!

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

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

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

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 , starting the flashing light.

If you are in situation one, then the TV 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.

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.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

It is a problem with your power supply board. It is most common on LCD tvs. If you know a little about electronics and soldiering you can fix it. What you need to do is take the back of the tv off and find the power supply board, easiest way is to follow the connector for you power cord up to it. Then i want you to look at the capacitors on the board, the are the cylinder looking things and they should have a metal top to them. Those tops are suppose to be flat, if any of them are raised that means that capacitor is bad. You can read the rating of the capacitor on the side of it and by new ones. I would suggest high temp 105 degrees C ones for tvs. To take them off its as easy as taking the board out, desoldiering the two connections on the bottom, pulling it off, and sticking in the new one and resoldiering it. Make sure when you put the new ones on that you line up the side with with the positive line to the same side that the old one came from, the positive line looks like a greyish stripe down the side of the capacitor. Do this to all that apply, you will need a desoldiering gun that cost like 10 bucks at a radioshack to take the soldier off properly.
