The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

what error code is found if do self check?

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..

yes they provide a free service manual with their kits. the symptom of the blue screen could either be the signal or the FMT as they can both cause those symptoms, My professional guess would be the signal board as the FMT will cause distortion lines across the screen with no picture.

Sounds like many different problems maybe related thou. You say 6043a but you are under WD-62327. So this info is for that.1. Suspect the Light Engine part # 939P977020 also you could need.. Suspect the Signal PCB part # 930B923002 if no video keeps up
