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".

AC Power Requirement

Note
1) Caution!

This PDP uses a 240V source and consumes 1,500W of power . Check the customer's AC power source. 2)Maintenance space! A minimum space of 700mm is needed at the rear of the unit for installation. 3)Please check with the Sales company for the service and maintenance contract.

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.
