Precaution


10. Safety Indication:
Some electrical circuits or device related materials
require special attention to their safety features, which
cannot be viewed by the naked eye. If an original part is
replaced with another irregular one, the safety or
protective features will be lost even if the new one has a
higher voltage or more watts.

Critical safety parts should be bracketed with ( ! ).
Use only regular parts for replacements (in particular,
flame resistance and dielectric strength specifications).
Irregular parts or materials may cause electric shock or
fire.

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.
