There may be a problem about power supply. Check main supplies with a voltage-meter. Also there may be a
problem about SW. Try to update TV with latest SW. Additionally it is good to check SW printouts via
Teraterm. These printouts may give a clue about the problem. You can use mini scart for terraterm connection.
