Does anybody have any idea how to get this set working again? The set will not power up. The processor just sits in a loop when power is first applied. The degaussing relay gets energized and the set powers up without raster or sound. Pushing any button powers the set off. By lifting the data lead on the serial prom, the set will come on with a blue screen, but does not respond to anything other than the power button. The clock and data signals have normal 5 volt amplitudes. Is there a secret to getting some default values into the eeprom??
