Please read this page before repairing the monitor.
This page explains the following items for keeping the safety of the set and preventing
accidents during repair.
Symbols used:
Warning
Caution
This symbol means "CAUTION"
This symbol means "POSSIBILITY of
ELECTRIC SHOCK"
Follow instructions.
Special attention parts are indicated
on cabinet, chassis and parts by label.
Please follow the notes in [Safety In-
structions] in the User's Manual.
Prevent electric shock.
Take care during working because
the monitor has high voltage parts
and power supply parts.
Possibility of electric shock if these
parts are touched.
Disconnect the mains plug during
overhaul, reassembly or parts change.
Death or injury by electric shock may
occur if live parts are touched.
Use recommended components.
Components and parts with special
characteristics for safety or reliability
are indicated in parts lists and circuit
diagrams by the
Electric shock or fire may occur if non-
recommended components or parts
are used.

WARNING
Keep the same style of wiring.
The Monitor uses insulating tubes
or tapes for safety and some comp-
onents are kept at a distance from
PCB surfaces for safety.
Internal leads are kept from hot- or high
voltage parts by clampers or styling.
Return wiring to original condition after
repair to prevent electric shock or fire.
Perform safety check after finishing.
Every part (removed screws, compo-
nents and wiring) should be returned
to its original condition.
Check around the repair position for
damage and measure insulation
impedance by using a meg-ohm me-
ter.
Confirm that the value of impedance
is more than 4M ohm.
Electric shock or fire may occur if
the value is less than 4M ohm.
The code and combination circuit of the
HDCP is not a repairable item.
Never remove the shield case that is
assembled to the code and combination
circuit of the HDCP.
