1. SAFETY INSTRUCTIONS
Part 2: Repair Information
2-1
WARNING:
The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary
side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot
circuit is identified with the line (
) in the schematic diagram. For continued product safety and
protection of personnel injury, servicing should be made with qualified personnel.
The following precautions must be observed.
1: An isolation transformer should be connected in the power line between the projector and the AC line
before any service is performed on the projector.
2: Comply with all caution and safety-related notes provided on the cabinet back, cabinet bottom, inside
the cabinet or on the chassis.
3: When replacing a chassis in the cabinet, always be certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers or shields, barriers, etc.
DO NOT OPERATE THIS PROJECTOR WITHOUT THE PROTECTIVE SHIELD IN POSITION AND
PROPERLY SECURED.
4: Before replacing the cabinet cover, thoroughly inspect the inside of the cabinet to see that no stray
parts or tools have been left inside.
Before returning any projector to the customer, the service personnel must be sure it is completely safe to
operate without danger of electric shock.
Product safety should be considered when a component replacement is made in any area of the
projector. Components indicated by mark
in the parts list and the schematic diagram designate
components in which safety can be of special significance. It is, therefore, particularly recommended that
the replacement of there parts must be made by exactly the same parts.
Eye damage may result from directly viewing the light produced by the Lamp used in this equipment.
Always turn off Lamp before opening cover. The Ultraviolet radiation eye protection required during this
servicing.
Never turn the power on without the lamp to avoid electric-shock or damage of the devices since the
stabilizer generates high voltages (15kV - 25kV) at its starts.
Since the lamp is very high temperature during units operation replacement of the lamp should be done
at least 45 minutes after the power has been turned off, to allow the lamp cool-off.
