MAIN
CAUTION
Components indicated by a mark ! in this schematic diagram have the special
significance in the safety. It is therefore, particularly recommended that the replace-
ment 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.
