Introduction


1. Basic concept of how to determine the defective board
   1) Verification of voltages
            Normally, when there is a power problem, shutdown occurs immediately.
            So, to resolve a power problem, voltage checks are necessary before shutdown.
   2) Check if the power comes up after disconnecting the board under suspicion.
           If power comes up (*) after disconnecting a board, the board is defective.
           (*) "Power comes up" equals "no shutdown".
2. Troubleshooting Video and Audio problems
3. Examples of video problems
4. Adjustment after PCB exchange
   1) After exchanging the following boards, voltage adjustment is required.
        P board, SC board, SS board => Please refer to the "Service Manual".
