I've never worked on a "Prima", but your problem is definitely micro-related. It seems to be performing the POR (power-on-reset) and nothing more. Have you checked the crystal (or resonator) that feeds the clock signal to the micro? I've seen a few Sanyo and Sharp sets that had bad/dead micro clock crystals. Then again, it could be a stuck data line from the EEPROM to the micro - scope those out to see.
Cheers,
