Question about Televison & Video

A gateway plasma tv model gtw-p50m103, no longer powers on. For awhile the tv would be on and then just turn off, now we get no picture. No lights come on the front of the tv. For a long time there was a power button problem on the front of the tv,when we would turn on the tv with the button on the front the tv would just turn off right away.

It sounds like the power board to me.

The problem is most likely the power board failed, or possibly a fuse. Power button problem would indicate either the button is not working properly or the power board has a problem.

Would suggest to have it looked at by a professional to confirm what the problem is before replacing parts other than fuses (cheap parts)

Either the power button had failed completely or you have a defective power board inside.

The only way to find out is having the tv taken apart and inspected by a technician.

    The TV must be taken apart, first the power switch must be tested, if this is fine the power board must be tested. First looking for bulged capacitors and components that had blown, and then using a multimeter.
    The job must be done by a technician.

    This should also mount on your model, call the seller to order the right part for your model if you need to replace the power board.

Chances are there are cracked solder on one of the boards. This is a common problem with Gateways. If you're handy with soldering then this is an easy fix.
