CAUTION
Components indicated by a mark ! in this schematic diagram have the special significance in the safety.
It is therefore, particularly recommended that the replacement of those parts must be made by exactly the
same parts.Must be used with a specified fuse. Unauthorized substitutions may result in fire or accident.
This projector is isolated from AC line by using the internal converter transformer. Please pay attention to
the following notes in servicing.
1. Do not touch the part on hot side (primary circuit) or both parts on the hot and cold sides (secondary
circuit) at the same time.
2. Do not shorten the circuit between hot and cold sides.
3. The grounding lead must be connected to the ground of the same circuit when measuring the voltages
and waveform.
CAUTION
Fuse of the specified parts number must
be used.
Unauthorized substitutions may result in
fire or accident.
