Question about Projection Televisions

1 Answer

Hi: My TOSHIBA 42HP83P works well for first 20-30 min. after that half of the upper screen will discolor or black out. I guess it might be overheating somewhere because it took longer time to develop that problem when i put a fan to cool it off from the back but i noticed that two cooling fans on the upper top of the unit were running. Thanks in advance. Ian Scheeh

    The is a heavy plasma TV.
    I will do more study before I take it off the wall and open the back
    to replace the fans. One of them was making noise before but there were
    running when I checked them last time. And I could not tell if it ran
    in proper speed or not.

The bottom half of the screen of my old Toshiba rear projection tv is black. It will usually correct itself after about an hour of warm up. What is the problem and how can it be corrected?


Hi ,it has to do with the light engine.Either the DMD board and this it how it works:http://electronics.howstuffworks.com/dlp1.htm Basically if your tv is a dlp it has a chip that carries 2 million pixels when those chips are in the off position you'll get lines or discoloration.God bless you and your family.

Toshiba tw56x81 rear projection tv "protection fault"


Try unplugging and waiting about 2 min. Then retry. There is a self protection circuit which is what is stopping the unit from coming on, but it can be triggered by many things. [Units this old are famous for the capacitors (electrolyte dries out and then they blow), but that is just the most common problem. I would look the capacitors over and see if they give any indication of being "blown" (discoloring, etc.) and replace them if they do.
