Question about ViewSonic VX1935wm LCD Monitor

1 Answer

I had my ViewSonic VX1935M-3 Lcd Monitor shut off for 2 years, I tried turning it on now and the power button flashes blue but the screen stays black. How do I fix this?

My ViewSonic Monitor (VX1935wmM-3) was shut off for roughly 2 years, I tried turning it on yesterday and I plugged 2 out of the possible 4 things in(Vga cable and Power cable) and then the power button started to flash blue but the screen wouldn't turn on, it stayed back. My laptop (Toshiba running windows 7) registered it and acted like it was perfectly fine and there was no problem with it

The absolute worst thing you can do with a piece of electronic equipment is to let it set. If as you stated the laptop registered it OK then it could be that it has lost it's memory and needs the drivers updated. The laptop will only tell you that it is connected it does not run a diagnosis on it. If you have the disc for the drivers try running it while hooked to the monitor. Other than that you may have internal problems with the monitor. It could be the inverters. logic controls and numerous other things that just seem to die of neglect I guess you could say. I have found about every kind of problem with TV's and Computers that have been mothballed for a length of time. I would think it is the drivers though. If you do not have the disc go on line to the Mfg. of the monitor and enter the model # etc. and try to find a download for the drivers. Most Mfg. have free downloads of the drivers for their equipment. Hope this gets it going and if I can be of any other assistance please feel free to contact me.

SOURCE: Viewsonic VX900 turns on for second then shuts off

I had to replace a fuse(F1) on the inverterboard of my VX900 to get it back to life as fuzzytek sugested.

It was replaced by a normal "flat" fuse (for cars). Had no clue about the value, so I tried with 0,5A first. It blew right away. Next value I had was 2A, and it worked! (It might be too small, and it might be too big, but I think it is better to usa a "large" fuse rather than no fuse at all. :)

Some pictures from my installation:

SOURCE: Viewsonic monitor VG2021m won't awaken

I understand the vg2021m has a 3 year warranty. Phone number for Product Support is (800) 688-6688. Give 'em a call and see if they won't fix it for free or some nominal charge. (OK! So this is the cowards way out.)

SOURCE: Black screen, power button flicks

The monitor should come when the power button is pressed once - period. If not, and it continues to happen when connected to another PC, then the hardware is having trouble powering up the panel / ccds and it should be replaced/serviced according to the terms of the warranty. I suggest to bring it to an authorized service center for proper diagnosis & fix the problem. regards

SOURCE: ViewSonic 19" flat screen monitor goes black - intermittently

Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,
Graemevm

Very typical of View Sonic. Sounds like a back backlight or inverter. I would go to www.viewsonic.com and open up a RMA. Most view sonic screens have a 3 year warranty. They will repair at no cost ..(if it is within that period) There is a date code on the back of the screen that will help you validate the above information.

Monitor flashes on then goes black.


I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.

ViewSonic Monitor has trouble to wake up after been shut down.?


Well with this type of fault it is invairably a problem with the Power Supply, in the PSU Electrolytic capacitors dry out and often cause this type of exact problem... It is a relitively simple fix, by replacing the caps with new ones... Any good shop should be able to fix for a modest fee.. OR if ya know anyone handy with a soldering iron maybe they could do it for you there are generally about 4 - 6 to replace... in the PS section, just do them all to be safe..

ViewSonic Monitor has trouble to wake up after been shut down?


Ok sounds to me like a power supply problem.. this a a fairly common symptom. I suggest that as a temporary fix you set the monitor to NOT turn the power off to the monitor in sleep mode if possible, in your power settings for the monitor.
