OK, you replaced 3 caps. Did you replace with the same capacity and voltage? What brand and series did you use?
What do you mean by "but won't stay on constant"? Does the backlight turn on, then go off and stay off until you cycle the Power button on the monitor? Or do you mean the Power button flashes on and off, and the appears and disappears?
As a first step, replace C21

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 traces

Re: Viewsonic vx910
Set DMM to diode check. Measure from base to collector switch orientation of probes you should only get a reading in one direction. Do the same for base to emitter any short indicates a bad transistor.
Based on the pics of 2 inverter transformers (near the blue HV caps) you will have 2 transistors per transformer. Since I can't find them on the top side of the board they are surface mounted on the underside of the board usually as close to the transformers as possible.Last edited by Krankshaft; 10-02-2009, 08:16 AM.Elements of the past and the future combining to make something not quite as good as either.

Re: Viewsonic vx910
For those who are trying to repair this monitor, a service manual (actually for the Beleina 101910) can be found here. Thanks, pmm007 for the link.
The transistors mentioned are available as DK Qx from Fran's LCD Monitor Repair on eBay for $7.50 a pair plus shipping. OR they are available as 2SC4672 Q from Digikey (part number 2SC4672T100QCT-ND) for $.72 each.
To others who are going through the same hell I did, the transistors are labeled DK at one end and QH, QQ, QF, QD, etc at the other. The Q indicates gain, the second letter is a production code.
