This projector is isolated from AC line by using the internal converter transformer.<br />
Please pay attention to the following notes in servicing<br />
1. Do not touch the part on hot side (primary circuit) or both parts on hot and cold<br />
sides (secondary circuit) at the same time.<br />
2.Do not shorten the circuit between hot and cold sides.<br />
3.The grounding lead must be connected to the ground of the same circuit when<br />
measuring of voltages and waveforms.<br />
