All voltages check good, except there is no RUN voltage of 2.8 volts when the pwr button is pressed. I am thinking that the gemstar with built in microprocessor is at fault. I would like to change the eeprom first before I spend the $100 Canadian to replace the Gemstar, but none of my suppliers have this eeprom in stock. Can I sub in a known good eeprom from some of the older RCA chassis' like CTC176-187 for test purposes? Thanks.
