You have a failed EEPROM on the signal (main) board. Location is U16. This eeprom is difficult to remove. In this case you can order a a main board ($75). You must be sure to get an exact replacement. I have repaired many of these. with eeprom replaced only ($15.00 plus labor). Thanks for asking, Matt of Martins TV Repair.
