This sounds like you have lost your power supply. The more expensive the equipment, the more sophisticated the power supply that converts the power from your outlet into your television. There could have been a lightning strike that has disabled the tv. Or it could be a faulty outlet.
Before called for a technician, I recommend plugging the television into a different outlet. use a good quality extension cord if necessary. You may find that your outlet is not polarized correctly. If this does not work, please try our premium service or use our online listing of technician for a professional near you.
thanks and good luck :)

Why my gateway srs wow plasma tv that turns off on its own n sometimes doesnt turn back on


Fault with the main power supply regulator board.
Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis.

Hi ive got a teco 32 LCD television it doesnt seem to be responding to the remote and also the buttons on the the tv.on the screen it keeps saying 'Switching to DTV' and wont go off that.we have tried...


One of the things I'd try ( I can't say for sure if you can or not because you didn't provide a model number) is to disconnect the front panel buttons.
You can only do this if it leaves the infra-red still connected.
Turn the unit on with the remote.
This will eliminate a stuck front button as the cause.
If the infra-red transistor is part of the front panel board, you cannot use this method to eliminate the front panel as the possible cause.

The front glass broke.. where can i get another?


Every screen I've ever sween for sale is more expensive than a new tv itself. I'd try ebay or google and see if you can find one that doesnt work.

Thanks,
