I just fixed this problem and it wasn't the power supply. I made a video showing how to troubleshoot and fix this problem.

Check and replace its main power regulator board. It is faulty. Not working.

Check the speakers. If they are OK, replace audio output card.

sounds like a bad prejector bulb

Are you sure you are installing it correctly? Try both sides and then see if it is accepted. If not, then the drive is bad

Hello! I wanted to give you a few more codes that you may not have tried. I also wanted to give you the instructions to the power scan, which will scan the TV for the correct code. I hoep this helps!

Codes:
500
795
719

Power Scan:
1. Hold down the Clear TV button until all lights at the top of the remote light up
2. Press the red TV POWER button
3. Press and release the up arrow on the remote about once a second until the tv turns off.
4. When it turns off, press the # (Pound) button
5. Try powering the tv on/off, and try the volume. If one or more of these functions do not work, start over at step 1 again.
