Toshiba 46XV645U will not power on

Turned TV off in the middle of the afternoon. Returned a couple of hours later and it will not power up. No lights, no noise, just will not respond. There has not been anything unusual happen, no storm or anything. Changed to a new electrical outlet, tried another remote, tried turning it on with the button on the side of the TV.

SOURCE: LCD TV WONT POWER ON

A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.

First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.

If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.

SOURCE: tv wont turn on

I had the same problem and took it apart. Before the repair there was no "click" when I pushed the button, a clue to the problem. The on-off button on the front pushes a weakly made angle piece of plastic inside which had broken. The plastic piece in turn is supposed to push an internal switch which is offset to one side.

I used epoxy (Araldite) to repair the broken plastic angle piece, but it still looks weak to me so I switch the tv off at the wall and leave the on-off button alone (though it does work now).

Opening the case requires some knowledge and care, and can be dangerous. It may void the warranty so be careful or give it to a qualified repair person.

Hope this helps!
