Television and Home Theater

Hello, I have a WS-65513 that recently started displaying only the primary tuner and the composite video inputs (1,2,3) in Black and white.

All menu's, and digital inputs (DTV ant and component inputs work great.

Th epicture quality is great on all inputs, just missing color on the ones above.

Any ideas where to start??

Thanks

Toshiba Theaterview TV TP48E60 picture was fuzzy and now all I have is sound no picture.   Is the picture tube out?  If it is, is it simple to change? Does anyone have schematics and/or pictures to replace the tube?? Does anyone know where I can buy the tube?  Thanks in advance...  Hector

Hi all, i am looking for dead or alive light engines for Hitachi 50v500 or 50vx500 free or cheap. i am making aftermarket internal parts for these and need test engines. Please send me a message if you have any kicking about. they dont have to be complete light engines.
