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. Troubleshooting shutdown problems
