The tv is 3 years old. The television shuts off every 2 minutes or so... When starting back up the power indicator flashes like a computer when on sleep mode.

The power indicator on the tv, does it flash a code? (example 6 blinks pause 6 blinks pause repeat)

There are a couple of things that could cause this, unfortunately there is no reset for this television other than unplugging it. It will have an internal failure at this point. I will try to explain the possibilities the best I can.

First you could have a failure in the power supply, we have seen some capacitors fail in your model and cause funky problems like this. If this is the case you could be looking at somewhere around $175-$200 to fix the set. IF the power supply had to be replaced you could be looking at $250-300

Next could be the main board, this would not be good news because you could be looking at $300-$400 for the repair (I know this is up there in the price range and most likely getting over the cost of a new set)

Any of these could cause your problem, but it will require troubleshooting to determine the exact cause of your problem. If you have experience, and test equipment and would like to attempt some troubleshooting I will be happy to assist you, however if you do not have equipment or experience then you would need a repairman at this time to get an exact diagnosis. I am sorry that I don't have a quick fix or easy answer for you on this one, it is definitely an internal failure.

If you would like any additional information or have more questions please don't hesitate to ask!

Thank you,
Tim Nolan
