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 hot and cold
sides (secondary circuit) at the same time.
. 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 of voltages and waveforms.
