Re: Viewsonic vx910
Maluko75, I do not have the board in front of me anymore.
The transistors on the bottom and surface mounted. they will have lettering of DK QB or something like that. Digi-key has them they whole repair should cost you under 10 dollars with parts to spare.. and take less then 20 min if you can unsolder the transistors without braking the tracesLeave a comment:

Re: Viewsonic vx910
When i fix the VX910 and vx924 monitors with the same problem i replace 4 electrolytic caps and two ceramic by the transformers. I also replace 4 transistors on the bottom side.. This cures the problem 100%Leave a comment:
