My 73" Mitsubishi tv #73640 has sound, but no picture. What does this mean?

SOURCE: have 73 inch mitsubishi tv

i want to know wy my tv sometimes turn on and sometimes not and the green liht is allways flashing

SOURCE: picture dimming and an ominous clicking sound

If this set is really only 5 weeks old, place a warranty service request for repair. This should not be happening. Either the ballast is bad or the lamp. In any case, either should be covered under warranty.

Please keep us updated.

Thanks,
Dan

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..

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
