There may be a problem about power supply. Check 12V_VCC, 5V_VCC and 3V3_VCC 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 hyper-terminal (or Teraterm). These printouts may give a clue about the problem.

No Sound Problem
Problem: No audio at main TV speaker outputs.
Check supply voltages of VDD_AUDIO, 5V_VCC and 3V3_VCC with a voltage-meter.
