This tv had a standby light but wouldn’t respond to the power button. I tried freezing the eeprom but that didn’t help either. I ordered a new main board for the tv and the board fixed the problem though I still suspected the old board had an eeprom issue and could be repaired. Eeprom was marked 25Q64B and I ordered some replacements on ebay from China. I read the eeprom off the new board with my CH341 programmer. Once the new eeproms arrive, I will program them and test with the old board.
Update: I was successful in reading the suspect bad eeprom once I removed it from the board so it was unlikely an eeprom issue. With a new eeprom, tv did not turn on so I ended up using the replacement board.
