This TV was working before we recently moved it -- without dropping the
175 lb beastie! Now with no inputs the raster is all white instead of all black as it used to be. The brightness and picture controls (as well as all of the other menu items) appear to operate but the raster remains a saturated white. Unlike the main picture, the PIP picture has reasonable contrast but it has no color, only black and white. You can see a just a tiny bit of detail in the main picture. Looking at the schematic makes me suspect that the PIP control is shot but all else is likely okay. Any opinions on what may be wrong with the TV and where I might be able to source a replacement circuit board?Thanx!
