By now this aging TV has many, many bad solder grounds. The first place to start, is to pull the convergence board out. You will see an STK-393-110 that has rings around the pins. This is bad grounding. Please resolder this, and do not use excess solder or you will short the pins together. Then you should inspect the board for any and all ICs attached to heat sinks and resolder the pins to the board. Look for bad grounds on power resistors, transistors, diodes and capacitors. Also resolder areas where the board meets the other board. These are jumper jack connections. These can be a problem, solder as necessary. The second board to inspect is the power supply. It is the one with the flyback transformer. The first thing to find is the vertical IC. This is usually the reason you have no video. Please resolder the pins of the vertical IC.Do not to use excess solder or you will short the IC. Resolder the flyback transformer,horizontal transformer,power resistors, capacitors, transistors attached to heat sinks etc. Resolder the jumper jack connections that connect the boards etc. I cannot say enough, you must really inspect to find these bad grounds.I do not believe you need to replace any parts now. Just resolder and reinstall. This will take great patience and skill. Thanks for asking and show a few hands of support!

Hi, can you tell me what you see on the screen? It could be a bad cable. Are you using an HDMI cable or the color cables (RCA cables)?

What can I do about my Mitsubishi WD-65737 having a dark screen and cutting itself off? We have already replaced the bulb and ballast.

Can you link a picture of the issue? If the picture is bright in some areas and not in others then it could be anything from the lamp lens, light tunnel, or any other mirrors or lenses. If the picture cuts off sharply, it may be something else. A ballast wouldn't cause that but a lamp could. Make sure the bulb is an Osram brand or Philips. Any knocks offs are not to be trusted regardless of how good they say it is. Without a picture or video of the problem, its hard to determine where the problem lies.
