Look for bad caps as shown in my pictures first.

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 VIEWSONIC 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.

No power to vx2235wm. How can I fix it?


Black screens or no pictures are usually caused by a failure in the back light power supply. Many times the monitor is working but with the back lights not turning on you can't see the display. Here is a link to a repair guide that will show you how to open the unit and what to look for and replace to rebuild the power supply and bring the unit back to life.
