Question posted by peterling on October 12th, 2012
No Power
I have a VS12107 Veiwsonic monitor that users an emax pwr0502204001 inverter board. The bridge rectifier failed and the chopper control chip I have replaced them but the monitor fails to work. I have the 5v rail and the 12v rail but the 12-v rail cannot source enough current to power the backlights. The screen keeps flashing and when trying the 12v rail falls. I have injected 12v from by bench PSU and all is fine with the monitor. I have looked at the feedback loop for the PSU and it seems to be trying to control the pulse width. I am now wondering if I have the correct version of the chip as the numbers on the one I removed where nor very good. I would really like a circuit diagram or if any one has the chip number for this board it would also be good
Cheers
Peter
