Re: tv shuts off
Remove all the external connections connected to the tv.then un plug the tv wire from the power outlet.then after some time just plug only the tv wire back in the power outlet.do not connect the other devices and check if the tv is working as normal or not.if it does not works then
its the problem in the power supply board of your tv. check for the fuse on the power supply board. for any blown capacitors or ics.on the powersupply board. also check for any loose soldering joints on the power supply board.
calling a tech is much advisable.if do not have proper technical knowledge.
it will not be too costly to get it repaired. it is worth getting it repaired.as this is a common fault faced by many customers.

Its is a cold solder joint on the board. The board is the one located at the bottom right of the tv when looking at the rear. Mine did the same thing. After refreshing mose of the large solder pints on the board, it stopped. Hope this helps!
Good Day, 1bigmoney;
Try resetting the SAT box. To do this unplug box for 2 to 3 minutes then plug A/C cord back in outlet. If no fix have SAT. box replaced, after making sure all cables on BOX are secure.
Good Luck, big IRISH.
Take off back cover. The problem power board is to the right of the
board where the power plug feeds into the TV. There is a large white
fuse right bend the power plug. With a meter it read ok; about 8 inches
deeper into the TV on that board was the resister next to two fuses. My
4 amp 125 volt fuse did not read on my meter. After replacing, it
sounds like the high voltage transformer or could be high voltage off the tubes.
not a good idea to keep this running as it will cause more damage, best to have service tech look at this since it's high voltage.
Be careful. This same problem burned a mark in the Blue crt on my
pro730HD. Three months and the Service Tech and Pioneer have been
unable to determine the cause (they claim). In the process they have
blown two more crt's.
When your tv goes off, try turning it back on using the main power
button instead of the remote. The button should be behind a flip-down
strip below the screen. When it is working again, look for any faint
colored spots in the picture most prominent on light backgrounds. Mine
is a yellow Y in the center of the screen.
If there are no spots, I would suggest you don't use the TV until you
get it fixed because eventually it will damage your crt ($750). Of
course, as I said, they have been unable to fix my problem and I have
had no TV for three months.
