Be sure to read this manual before servicing. To ensure safety from fire, electric shock, injury, harmful
radiation and materials, various measures are provided in this Plasma Monitor.
Be sure to read cautionary items described in the manual before servicing.
These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric
shock, do not perform any servicing other than that described in the operating instructions unless you
are qualified to do so.
Service Warning
1. Since the Panel Module and the front Filter are made of glass, handling the broken Module and Filter
carefully and with caution in order not to receive injury.
2. Replacement work should be started after the Panel Module and the AC/DC Power supply have
become sufficiently cool.
3. Special care should be taken when working near the display area in order not to damage its surface.
4. The Panel Module should not be touched with bare hands in order to protect its surface from
blemishes and damage.
5. It is recommended that you use clean soft gloves during the replacement work in order to protect not
only the display area of the Panel Module but also yourself.

DISASSEMBLY INSTRUCTIONS
1. REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC
REMOVAL
1. Put Masking Tape (cotton tape) around the Flat Package
IC to protect other parts from any damage.
(Refer to Fig. 1-1.)
NOTE
Masking is carried out on all the parts located within
10 mm distance from IC leads.
3. When IC starts moving back and forth easily after
desoldering completely, pickup the corner of the IC using
tweezers and remove the IC by moving with the IC
desoldering machine. (Refer to Fig. 1-3.)
NOTE
Some ICs on the PCB are affixed with glue, so be
careful not to break or damage the foil of each IC
leads or solder lands under the IC when removing it.
