Viewsonic vx2245 goes black every 30 or 40 minutes


Dear Miguel,
I think this problem came from some Capacitor of the monitor. I solved this problem with my Viewsonic VG2021M and I hope it should help you too.

Screen blanks after 3 seconds


Viewsonic uses cheap caps in their monitors, so look for bad caps with bulging top, replace them in a set.

I have a viewsonic va902b screen when I turn it on the picture flashes and wont stay on the screen, how do I fix it?


More likely to have bad caps in the power supply, that is the first place to check for bad caps with bulging top, it can also be bad inverter circuits, or bad lamps, open it up and post back what you see so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

I have a Viewsonic VX2245wm or VS11349, Works and then it goes black for 2 to 4 sec then runs for 10 to 15 min and goes black


Look at the power supply section for bad caps first, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Post back what you see inside, it can also be caused by bad inverter circuits or bad lamps.

VA1703wb Viewsonic Monitor backlight


The problem can be bad power supply feeding the backlight inverter circuits due to bad caps, or in the inverter circuits, or worst case will be bad lamps, you need to open it up and tell us what you see inside first, good pictures will help, see example of failed VIEWSONIC due to bad caps: http://s807.photobucket.com/home/budm/allalbums

It's a Viewsonic VX715 Monitor. When it's turned ON, It goes black in 3 seconds.


It can be one of thses: bad caps (bulging top or bottom seal) in the power supply, bad backlight inverter circuits, bad lamps. You need to open it up and lool for bad caps first, then measure the voltages across the filter caps, you should have 5vdc and 12~18vdc (there are two power supplies: 5vdc for logic, 12~18vdc for backlights citcuits) Post back what you find so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Exactly the same problems.. It's been repaired 2 times and last night it went totally black... Bummer... but the image quality is excellent ( when it works) boooo viewsonic.. Natalie


What parts were replaced, or cheap parts were used? More likely to be either bad caps in the power supply, or bad backlight inverter circuits, see failed VIEWSONIC monitors due to bad caps here: http://s807.photobucket.com/home/budm/allalbums

Monitor turns black after 2 seconds, Viewsonic VX910


Check the power supply first for bad caps, then check to see if you do have 12vdc feeding the the inverter circuits, worst case will be the lamps, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
