Introduction
<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
5. 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”.

Chassis structure
The 103” plasma display television contains many more boards than the smaller size
plasma display models that are on the market today. It contains:
1. Two P boards (power supply)
2. Twelve C boards (data drive)
3. The SM board is added to complement the SU and SD of current model.
4. There are four DR boards added to the unit, one at each corner
5. There is the DS board that connects the HX, HA, and HDD to the DN board.
