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.
