    Our television turns itself off after 3-4 minutes. I've had a repairman out. He takes the tv back to the shop for a week and when he returns the problem is still there. He swears that the tv works in his shop. This has happened three times already and he wants to try for a fourth. The last time the TV worked when delivered, but there was no sound. He took the back off and jiggled the connector on the sound board and the sound started working. He put the TV together and I signed off on the delivery, within five minutes after he left it turned itself off again.

I have one I bought about four years ago and am starting to have problems with a refurbished one they replaced after they could not get the original one to work after replacing two of the four parts they were supposed to replace. Any suggestions?

    What do you think it's worth if it's still working but I can tell the color is going out and the Power is messed up?

Sorry to tell you a common problem with these sets. It is a bad capacitor in the main power supply.. There are really about three of them that go bad from time to time to cause this problem... If your not a tech you should find an authorized repair facility as a non authorized is not going to know what to do to fix it and it will most likly cost you double to repair. Good luck and let us know how you got it fixed.

I have a gateway 42" plasma television model # gtw-p42m102. When I turn on the main power in the back of the tv, it will turn on, go to a blue screen with an hourglass, then it will turn off and then...


Hi

Its not a power supply issue, but an issue related to the D-board on your TV. There would be swollen/bulged capacitors on this board. To check this you'll need to remove the back panel of the TV. Check the connections to and from the D-board. Make sure the lamp connections are fine and ballast is not burnt. Also check if all cooling fans are working.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

I actually bought the 5 year warranty when we purchased this new and it was still under warranty. Gateway is sending us a brand new TV. No need for me to try to fix this, but thanks to all involved.
