Question about ViewSonic VX910 19" LCD Monitor

1 Answer

LCD Monitor has no video

Hi, My Viewsonic LCD monitor has quit working. The screen is blank, and I have tried it on other computers, and the power button flashes on and off at about a 1 second interval. Can you tell me what it is wrong and perhaps where to get the part to fix it?

Sounds your monitor has either blown a backlight or the inverter board is bad. Either way they can both be replaced, but tracking down the parts will be a bit difficult. But your LCD Monitor is in trouble! Sorry!

    Ok here is the deal about these LCD monitors. I am called atleast three time a week because of the same problem. Most of the time it is a replacement LCD. These monitors are very fragile as they have backlights that are very tiny florecent lights that allow you to see the image being displayed. When this light starts blinking it is for a number of reasons:

    1. Power supply not generating voltage to display an image

    2. Inverter board is bad

    3. Backlight is blown

    These can all be either fixed or replaced provided you determine the source of the problem and track down the replacement part.

    But I will try a power supply replacement first then take it from there!

Hi, I have a ViewSonic VX2235mw LCD Monitor it was working fine then all of a sudden the screen turned off and now it wont turn back on. The power light is on and is Blue but no sign of life in the screen...


Hello,

This is a very common problem with this model after a few years of use. This problem is caused by a failure of the capacitors in the power supply board hat powers up the back lights in the monitor. When the back lights don't power up you get no display on the screen. Here is a link to a repair guide for that model that shows how to open the unit and what to look for and replace to repair the monitor.

I replaced the video board on viewsonic vx2235wm-5 now video turns on then off


That is a power supply problem not a video board problem. You will need to either rebuild or replace the power supply to fix that problem.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor with a blank screen


The monitor is about 2 years old, time to inspect the caps in the power supply first, look for caps with bulging top. The problem can also be in the inverter circuits, or bad lamps. See example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
