...agree with the others here, regarding cheap meters. I have an $11 meter I picked up from Wally World that I throw in the truck.
At home on the bench, I have a Fluke 8100B -- gotta love those nixies!

Re: 2 Viewsonic VX1940W buzzing and no signal
I got all the parts in (most from Digi-Key, a couple from Mouser because Digi-Key backordered them), and installed them on the inverter board.
As promised, a pic of the repaired board. ...as a bonus, a pic of the repaired monitor, moments after putting it all back together.

Re: 2 Viewsonic VX1940W buzzing and no signal
welcome to the forum, Neobyte.
my parts are in-transit. Digi-Key backordered one of the caps, so I ordered it from Mouser... also found a 120uF/400V radial lead replacement (Nichicon) at Mouser as well; the Panasonic unit from Digi-Key was a 'snap-in' with two short posts.
I should, hopefully, have all the parts by mid-week, and have my 19" WS monitor back online by next weekend.

Re: 2 Viewsonic VX1940W buzzing and no signal
okay, I will.
life may intervene, so it may be a week or two before I get around to completing the repair.Leave a comment:

Re: 2 Viewsonic VX1940W buzzing and no signal
...for those following along at home and/or vicariously repairing monitors through my experience, I've attached an image indicating the parts being replaced.
C1 and C302 are definitely bad (bulged)
C201 is questionable.
C205, C305, and C307 are being replaced in a preventative manner, as they are of the same quality as the failed capacitors (5x CapXon, 1x VENT). All being replaced by Panasonic caps....Leave a comment:

Re: 2 Viewsonic VX1940W buzzing and no signal
thanks for the suggestions.
attached is my DigiKey order... I would appreciate verification that I selected a suitable replacement for the 120uF/400V capacitor....Leave a comment:

Re: 2 Viewsonic VX1940W buzzing and no signal
okay, so a few hours later, and I've torn apart my VX1940w, and pulled out the power board. pic attached.
two caps are clearly in need of replacement (220 uF 35V)
I'm not sure about the other -- there's no bulging on the end, but the splitting of the plastic covering has me a bit concerned. should I just go ahead and order up a 120 uF 400V cap as well, and install it while I have everything apart?...Leave a comment:

Re: 2 Viewsonic VX1940W buzzing and no signal
you're right. ...but, then
A while back, my ViewSonic VX922 was giving me fits... it'd take more and more "power on" cycles for it to actually come on. Eventually, it wouldn't come on at all. At that time, I had owned the monitor for 2 years and 360 days (that's right, 5 days shy of the 3-year warranty period). I guess I was feeling lazy, and I had a [borrowed] monitor to use in the interim, so I got the RMA and sent it off to ViewSonic. Two weeks later, they replaced it with a [B][I]brand...Leave a comment:
