H. STANDBY ON/OFF PROBLEM
Problem: Device can not boot, TV hangs in standby mode.
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 Scart-1 for terraterm connection.
İ. NO SIGNAL PROBLEM
Problem: No signal in TV mode.
Check tuner supply voltage; 5V_VCC, 3V3_TUNER and 1V8_TUNER. Check tuner options are correctly set
in Service menu. Check AGC voltage at IF_AGC pin of tuner.
