• Check the connection between the FRONT CONNECTOR PCB and the VIDEO PCB.
• Check the soldering of CP4611 and CP4613 on the FRONT CONNECTOR PCB.
• Check the soldering of CN5402 on the VIDEO PCB.
• Check the soldering of JK5401 on the VIDEO PCB.
• Check the IC5401 power voltage and check the soldering of the surrounding circuits.
• The pattern between IC5401 and JK5401 is faulty.
