Hitachi CML171SXW LCD Monitor Service Manual (v1.1)

1. Precautions and Notices

1.1 Safety Precautions

Although LCD monitors are displays without high voltage as that in the CRTs, the

following precautions still should be take care of.

1) Observe all cautions and safety related notes located inside the display cabinet and on

the display chassis.

2) Operation of these displays outside the cabinet or with the cover removed involves a

shock hazard from the display backlight's inverter. Work on the display should not be

attempted by anyone who is not thoroughly familiar with precautions necessary when

working on high voltage equipment.

3) Before returning a serviced display to the customer, a thorough safety test must be

performed to verify that the display is safe to operate without danger or shock.

1) Many electrical and mechanical parts in this chassis provide special visual safety

protection. The protection afforded by them cannot necessarily be obtained by using

replacement components rated for higher voltage, wattage, etc.

2) Before replacing any of these components, read the parts list manual carefully. The use

of substitute replacement parts, which do not have the same safety characteristics, as

specified in the parts list may create shock, fire or other hazards.

1) When replacing parts or circuit boards, wrap the wires around terminals before

soldering.

2) Keep wires away from high temperature components.

3) Keep cable and their shielding in their original position so as to reduce interference.
