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.
Caution
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.
Service Warning
The LCD panel made from AUO is used for this product.

CAUTION FOR SAFETY
Please read this page before repair the monitor.
This page explains to following items for keep the safety of set and prevent to accident
during repair work.
We explain by symbol at happen the damage or injury when took wrong repair.
Warning This symbol means "possible to die or heavy damage"
Caution This symbol means "possible to damage or something will break"
We made the symbol as below, which are kind of following items.
This symbol means "CAUTION"
This symbol means "POSSIBLE to
ELECTRIC SHOCK"
This symbol means "MUST"
This symbol means "DO NOT"
Should be follows to instructions.
We indicates to cabinet, chassis and
parts by label, which are special atten-
tion part.
Please follow to note and [Safety
Instructions] of User’s Manual.
Prevent the electric shock.
Please take care during working
because monitor has high voltage part
and power supply part.
Possible to die if you touch to these
place by miss take.
Please disconnect power plug during
overhaul, reassemble or change parts.
You will die or take damage by electric
shock if you touch to live part.
Use recommended components.
Please use to same characteristic com-
ponent, which is same as previous for
your safety and keep reliability espe-
cially marked by in parts list and cir-
cuit diagram.
It is reason of electric shock or fire if
you use non-recommended compo-
nent.
Should be kept same style of wiring or component.
Monitor uses tubes or tapes, which
made by insulator, and some compo-
nents are keep distance from surface of
PWB for safety.
Internal leads kept from hot part or high
voltage part by clamper or styling, so
please return to original condition for
prevent to electric shock or fire.
Should be done safety check after finished.
Every part (removed screws, compo-
nent and wiring) should be returned to
previous condition.
Check around repair position for make
damage by miss take and measure the
insulated impedance by meg-ohm
meter.
Confirm the value of impedance, that
value is more than 4M ohm.
It is reason for electric shock or fire if
that value is less than 4M ohm.
Nobody can check and repair to the code
and combination circuit of HDCP.
Never remove the shield case, which is
assembled to the code and combination
circuit of HDCP.

REMOVAL
IC
Put Masking Tape (cotton tape) around the Flat Package
IC to protect other parts from any damage.
(Refer to Fig. 1-1.)
1.
Fig. 1-1
NOTE
REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC
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.
NOTE
Masking is carried out on all the parts located within
10 mm distance from IC leads.
Blower type IC
desoldering machine
IC
Heat the IC leads using a blower type IC desoldering
machine. (Refer to Fig. 1-2.)
2.
Fig. 1-2
NOTE
Do not rotate or move the IC back and forth , until IC
can move back and forth easily after desoldering the
leads completely.
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.)

Thin-tip Soldering Iron
NOTE
When the IC leads are bent during soldering and/or
repairing, do not repair the bending of leads. If the
bending of leads are repaired, the pattern may be
damaged. So, always be sure to replace the IC in this
case.
Finally, confirm the soldering status on four sides of the
IC using a magnifying glass.
Confirm that no abnormality is found on the soldering
position and installation position of the parts around the
IC. If some abnormality is found, correct by resoldering.
5.
Solder temporarily
Soldering Iron
INSTALLATION
Take care of the polarity of new IC and then install the
new IC fitting on the printed circuit pattern. Then solder
each lead on the diagonal positions of IC temporarily.

Use an isolation transformer when performing any
service on this chassis.
When removing a PCB or related component, after
unfastening or changing a wire, be sure to put the wire
back in its original position.
When you exchange IC and Transistor with a heat sink,
apply silicon grease (YG6260M) on the contact section of
the heat sink. Before applying new silicon grease,
remove all the old silicon grease. (Old grease may cause
damage to the IC and Transistor).
