My problem is that my samsung plasma tv will turn on and be good for about 30 minutes then the relay starts to click and goes dead. I must then remove all power from the tv and plug it back in to get it to respond to the remote. Once it is back on it lasts maybe 30 seconds to 5 minutes and shuts off again. Because of this problem i cant find a gross failure in any part on my meter. I suspect that a MOSFET is heating up and shorting out on the power supply.

Even if i change out all the transistors it would be cheaper than sending it off and i think it would be quicker. But thank you for the help.Comment
