Question about ViewSonic VP230mb 23.1" LCD Monitor
Screen resolution the screen resolution is poor one side of the monitor has great picture the other side has a greying color. When the computer is powered down and the monitor is on the full screen is black on one side and a grey black on the other., there is a distinct transition between color changes. Is this fixable with a bulb replacement or is the LCD screen going. please advise.
Blinking on and off is not always a capacitor issue, it is usually caused by faulty transistors at the high output transformers that light the backlights. Crappy board design ! But fixable in most cases.

The first thing to try is to make sure the power cable is tight. I know it sounds too easy but with the movement causing the power outage it sounds that or a broken power cable. Check the cable to make sure it is tight and it that isn't it, change the power cable. If neither of these work you probable have a loose connection between the cable plug and the power supply on the unit which will require soldering and professional help to fix.

Bad caps in the power supply, common problems. See examples here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20V912B/

You need to open it up and the first place to look will be the power supply, look for bad caps with bulging top, 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

Sounds to me that you have a bad connection/wire to the CCFL bulb on that side of the display. Should be an easy fix, do it your selfer thing.
