Thanks guys,I am done.This video board is bad,not available any where online for this Vx922 monitor.Ebay etc. nothing anywhere.Not worth spending more time with it.Time to get rid of the rest of it.Thankyou all for your professional help on this.Unless you guys know where I can get a video board for this monitor with DVI and VGA connections on the board?

Re: VX922 Contrast popping up and lowering it all by itself?
No fuse on this one.I am wondering if I am pluging in the connectors on the video board to the logic board the right way? The dot on the connectors doesn't make any sense for pin one and so on,do you no what way these are supposed to go by wire color to pin 1 on the 3 different connectors to the 2 boards? The connection to the LCD at the top is clean and good connection.Still Nothing but White Screen,now what?Leave a comment:

Re: VX922 Contrast popping up and lowering it all by itself?
Checked all connectors all plugged in tight,I replaced those 3 brown caps on the power board with new ones with the T on the top,also the little cap behind the regulators.All values are right and installed correctly.Could this be a problem? the power supply? That is all I did,no other changes.I have not pitcher,and no menu at all.Just a white bright screen.Leave a comment:

Re: VierwSonic VX922 and VX724 Bad CapXon
Hello,Here is the photo of my board I replaced the caps on,I bought them from ebay,and I think they are CapXon brand.The monitor is working fine except for this contrast popping up and lowering it to minimum on it's own....Leave a comment:

Re: VX922 Contrast popping up and lowering it all by itself?
Hi,I replaced all the caps about a year ago,and it has been fine.It still is fine on the picture side of things and powers on ok,etc.Just started this new thing of the contrast popping up on the screen,and lowering all by itself.I noticed that 1 small cap swollen a little so I replaced it.
The contrast thing is the problem now all other things are working ok.Any idea's where to go here? Buttons all check out ok with ohm meter,on and off.Leave a comment:

VX922 Contrast popping up and lowering it all by itself?
Hi guy's,I have done the repair on a Viewsonic VX922.Worked great for months,now all of a sudden the OSD contrast pops up on screen and lowers the contrast all by itself,and I can't stop it.If I shut down the monitor,hold power button for 30 sec. and then start up the monitor,it works ok with no problems for about 5min. or so and then the contrast pops up again,and lowers contrast,and I can't stop it,I can raise the contrast and as soon as I let go of the button,it lowers it all the way down all by itself??
any help much appreciated.Thankyou.
Had 1 bad cap bulging a C242 470uf... -
