    Possible EEPROM fault U7 needs replacing.
    Willing to help but I'm no expert.

      if its a funai it has somehow got in the service mode.
      you need an original remote to peel open to get the service mode button.

          you may need the original remote control as mentioned above you could also try replacing the eeprom with a pre programmed one or failing that if you can find a exact matching mainboard if cheap enough (make sure you match all numbers from your old mainboard and get one from a tv that has the same lcd panel as yours)
