Tv powers on but no picture just black
Lights up but no picture
brandonj984 just like anything else, you have to start checking somewhere. Use the flowchart as the beginning of your repair.
It might also help if you post some images of what your boards look like. Use this guide for that. I will allow us to see what you see.
I have not been a fan of repairing plasma TVs. They do have the best picture and color. In your case I would guess the power supply board has problems. Even if you repaired this, you will also need to replace the buffer boards. The buffer boards are those that light the screen. So, to save money, these are not really feasible to repair. Thanks for asking, Matt of Martins TV Repair.
