Notice

- Be sure to separate the power cord before disassembling the unit.

- Discharge the capacitors first when separating PCB's with high capacity capacitors such as SMPS, X Main Board, YMain
Board, etc. (Aspark may be generated by the electric charge, and there is danger of electronic shock.)

- Check that the cables are properly connected referring to the circuit diagram when disassembling or assembling the unit
taking care not to damage the cables.

- Take care not to scratch the Glass Filter in the front.

- Assemble the boards in the reverse order of the disassembly.

- The plasma must be layed down on a flat padded surface for disassembly and reassembly.

Troubleshooting

Samsung Electronics 4-1

4-1-1 First Checklist for Troubleshooting

1. Check the various cable connections first.

- Check to see if there is a burnt or damaged cable.

- Check to see if there is a disconnected or loose cable connection.

- Check to see if the cables are connected according to the connection diagram.

2. Check the power input to the Main Board.

3. Check the voltage in and out between the SMPS ↔ Main Board, between the SMPS ↔ X, YMain Board, and between the
Logic Boards.

No Power

Symptom

- The LEDs on the front panel do not work when connecting the power cord.

- The SMPS relay does not work when connecting the power cord.

- The units appears to be dead.

Major Checklist

The SMPS relay or the LEDs on the front panel does not work when connecting the power cord if the cables
are improperly connected or the Main Board or SMPS is not functioning. In this case, check the following:

- Check the internal cable connection status inside the unit.

- Check the fuses of each part.

- Check the output voltage of SMPS.

- Replace the Main Board.

Troubleshooting

Procedures

Is the AC IN socket connector and

the SMPS CN800S connected?

Insert the AC in connector and the

SMPS CN800S connector

Is the Fuse (F801S) of the SMPS

Power Input Part blown?

When the unit is repeatedly turned on and off

Symptom - The SMPS relay is repeatedly turned on and off.

Major Checklist

In general, the SMPS relay repeatedly turns on and off by the protection function due to a defect on a board
connected to the SMPS.

- Disconnect all cables from the SMPS, operate the SMPS alone and check if the SMPS works properly and if
each voltage output is correct.

- If the symptom continues even when SMPS is operated alone, replace the SMPS.

- If the symptom is not observed when operating the SMPS alone, find any defective assemblies by connecting
the cables one by one.

Troubleshooting

Procedures

Caution

When separating and connecting the cables such as CN810, CN809, CN808, CN807 of the Main SMPS, CN4701
of the X Main Board, and CN5707 of the Y Main Board, a spark may be generated by the electric charge of the
high capacity capacitor. Therefore, wait some time after disconnecting the power cord from the unit.
