my neighbour's son killed my projector's power supply, I tried to get data
from ASK (represented by InFocus) or a circuit diagram in order to repair it.
Unfortunately I was told that they cannot (do want to ...) help me.
way I did some investigation inside the unit and found out that the first
stage of the switching power supply transforms lines voltage into 390V DC.
390V DC!!! This is pretty much. But this is well inside my personal voltage
range.... 3 hours later the power supply was built up: Siemens power
transformer from 6SELA 2600 amp + some additional parts.
