Toshiba tv screen goes black every 5 minutes with sound still on


Is it ok when you watch regular TV thru the cable or sat?

Black bar


On a non H.Def plasma, there is a PCB that runs along the bottom of the screen that is attached to the screen by a several brown/gold colored flat ribbon cables. I've seen where this ribbon cable is not seated properly in the jack. The ribbon cables are generally responsible for that section of the screen. Next possibility is the PCB itself is defective.
Not to scare you, but the plasma screen itself is a possible suspect.

Toshiba M45-S331, Black screen


I just went through all this myself. First I had the inverter replaced ($200) and it worked great for a week, then the screen went out again. It turned out that the LCD needed replaced ($200 more, labor comped from the first no-fix). There's a problem with the Toshiba LCDs that makes them burn out sooner than other brands. Since the replaced screen, no problems (2 months). Sucks, I know.
