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.

Unplug the unit for more than just one minute, let say at least half an hour. Let me know how many times the led blinks, probably the unit need repair.

Hello,
Dont worry, the problem is coincidental to you installing the Wii. You need a new lamp.
What you are seeing is the lamp ballast/power supply attempting to start and restart your lamp. The resistance of your lamp to it's power source has increased to the point that it is shutting down, but has not blown out yet. You can find these at justlamps.com
Good luck

Mitsu WS-55411 RPTV-power going on and off..won't stay on!


Hello,

It is possible that the Low Voltage power module is defective, however I would first check the High Voltage power supply for bad capacitors (they tend to go bad first). In fact check both boards for bad capacitors (they will look puffy in appearance if they are really defective).

I hope this helps,

Thank you,

If you are familiar with TV repair, have electronics basic knowledge, good soldering skills and tools then check dry (cold) soldering joints at D board of this TV. Resold all lose connections there and check picture.
Still no joy then you need to replace D board.
