SOURCE: Viewsonic VX910 powers on, screen displays for 1 second then turns off

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.

SOURCE: ViewSonic VX2235wm monitor looses power ...

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.
Good Luck,

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:

We understand that your problem is: Hi I have a ViewSonic Viewpanel Vp230mb and I am having this issue as to when I turn it on it will only stay on for a couple of days at a time and then will just shut...

90% failure in LCD monitors are due to bad DC filter caps in the power supply as you can see in my albums.
Capacitors kit: he can make you a set of caps for you.

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, 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:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My screen size will not go back to original size to large to wide

If you are referring to the screensize of your browser you can adjust this by pressing ctrl on the keyboard and using the wheel in your mouse. If this is about how your desktop is displayed you will need to right click on the desktop > screen resolution and adjust the dimensions.

Vp230mb power supply

Follow the ribbon cable from the pwr supply down to the motherboard. Near where it connects there are two "U" shaped wire loop test points. One is positive, one negative, 12V at 7.5amps.

Solder onto these. There is one other "S" wire which is for voltage sense. Don't know what to do with that one.

Inspite of all the wires in the ribbon, half are + and half are minus 12V, but it really needs the 7.5Amps.
