If it turns off after a while that's a transistor going hot.
You need a technician to test it for you. If you want to do it yourself
let me know. Good luck.

The unit has a fault on its power board and sustain board.

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.

SOURCE: Blue color spread over the pictures

This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.

Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.

Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.

The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.

You will have to take the set in to have it serviced.

Might be some loose solder terminal/s at its horizontal output section. The set should be checked.
