3-1 Overall Disassembly & Reassembly

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, Y Main Board, etc. (A spark 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.

4-1 Troubleshooting

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, Y Main Board, and between the Logic Boards.

Troubleshooting

4-1-2 Checkpoints by Error Mode

■ No Power

		- The LEDs on the front panel do not work when connecting the power cord.
	Symptom	- The SMPS relay does not work when connecting the power cord.
		- The units appears to be dead.
		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:
	Major Checklist	- 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

■ When the unit is repeatedly turned on and off

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