I have a 1 1/2 year old Panasonic TC-P42U1 plasma tv. While watching a show, it suddenly shut off and won't come back on. What do you think caused this and how can i fix it? Thanks.

This should help diagnose the problem.

the number of blinks will determine problem area.

its possible with that age---see photos to know what to look for:

its a lcd ? replace the lcd lamps or the inverter

The amplifier needs to be whatever you used for the TV, (EX. TV, DVD, Aux) in order to play sound thru the amplifier.

Hello!
First move: unplug your broadcast provider's box, wait for a minute, then plug it back into power source. I mean: leave all the connections intact, just unplug from power source. It might be just power cord or power adapter. If that's not the case, please do the same with TV. Unplug it from wall outlet, wait a minute, plug it back in. It's a next step, if your "box" won't take care of the problem. If that won't take care of the issue, refer to owner's manual for "reset" procedure. Worst case scenario: you might need to replace main board inside or your TV.
good luck,
Thanks,
Alex.

This is a fault in the power supply (at the very least) and needs to be repaired by an experienced tv repair engineer.

I have an old Toshiba TV and was going to replace it with a new plasma because it has suddenly (the week of July 19, 2010) lost color. It has only green and blue tint. Changing the "tint" on the menu didn't help. The color comes and goes relative to nothing that I can measure, such as how long it is turned on, etc. Reading other complaints from owners of Plasmas, I am thinking it is cable related. I have Charter Cable. Playing a DVD, I have to readjust the tint back to normal. Hope this info gives clues.

Get the TV audio from the Dish box directly to the receiver.

i have the same problem on my tv and i call to bestbuy since the tv is only 2months so still on the manufactures warranty the problem is SC Board shorted, and they replaced the sc board.
