Take a flashlight and at a angled view see if you can see the picture, if you can the lights burned out in the back

Hi!
That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board

After replacing blown capacitors...it should work again.

Things you will need.
1. A plastic flat end screw or any object with flat ends....to fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Or try replace light engine..if the above solution won't work..

I get sound but no picture then the tv shuts off after 5min. It is a Mitsubishi wd-73837
Popping noises are not a good sign; I suspect the sound came from the catastrophic death of an electrolytic capacitor or worse, the death a a power semiconductor.
Open the lower cabinet and using a good light, look for a smaller, separate board with fairly large parts on it; some cylindrical in shape, others block-like that may have copper wire showing.
If, as common, this board is plugged with connectors into other parts of the system, you may be able to swap the failed board out for a replacement bought from a Mitsubishi service center.Expect to pay $100-$150 US if the set is no longer under warranty.

Tv will not power on normally. The green light flashes intermittently and when the power does come on it has sound but no picture. Tv has been well taken care of and is less than 2 years old.
