Bought this for $40 for my son to Game on so I could get my front projector back. Found a blown Zsus fuse and shorted ipm. Also found an open 20ohm 1w resistor nearby.
Ordered an ipm from China, installed and changed the resistor and she fired up. Had some image retention which seems to have been cured by adjusting Vzbias from 173.5v down to 170v as per sticker. Still need to check the other voltages to make sure they're in spec.
Now to clean out the dust - this thing is thick with it ! It has two fans, one blowing over the ysus and a squirrel cage at the top. Is this the result of active cooling ?
