Proview 986m 19" monitor
Monitor erupted in much smoke and loud hissing. Video scrambled but
stayed up. I lunged for the power cord behind it, and unplugged it within 2 seconds. I took it apart, confident in finding some burst cap or two. Nothing. Everything on close visual inspection looks good. No burned traces or bulging/fried components. The board fuse is OK. I've repaired this monitor twice since new in 2000. A couple caps in the PS (would't start), and reflowed neck board (video brightness up/down). Could a fbt do this, and not show any signs? Something definatly gassed out violently. It smelled more like burned insulation than the acrid fried cap smell. I'm not competent to power up the board with it apart. JR |
