CAUTION
Components indicated by a mark ! in this schematic diagram have the
I 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 trans-
former. 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.
J
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.
K
Indication of Signals
Power Failure, Fan Failure Detection Signals
- NO POWER when one of those signals detects a failure.
Power Drive, Fan Drive Signals
- NO POWER when one of those signals has a failure.
Switch Signals [AV switch, Mute, etc]
L
- NO PICTURE or NO SOUND when one of those signals has
a failure.
