Subject: [TechAssist] Panasonic TV/ VCR PV-M1358W-K Chassis KM-138, black
box on screen


> Customer called me up and says that he was adjusting the clock in the
> menus and from then on he has a big black box on the screen (all except

> Sometimes the letters [ffff] in white lettering show up in the top left
> corner of this black box. When he changes channels, the picture is ok
> for about 5 seconds then the black box returns. Problem occurs during
> VCR playback also. The regular green colored on-screen graphics are

> Does anyone know if this is just some kind of microprocessor glitch that
