ViewSonic E70fB Brightness & Contrast problem
Sounds like the buttons or the button panel are messed up. Or it has gotten moisture in it.
The only time i have seen this was when one of the buttons were malfunctioning, and we ended up replacing the monitor.
I have a Viewsonic VA1916W-4
We had a similar problem with a bigscreen TV. We feared the worse, but after calling our local repair service, they told us this was a common problem involving a poor solder joint. They came out and fixed it in 15 minutes. Start by Googling your model number and "green" or "troubleshoot" to see if this is a common problem. If so, you may be able to fix it yourself or print out the issue and take it to a reputable repair shop or authorized dealer.

Hi, My Viewsonic vg2021wm says
All the caps with the white paste or dots in the middle or swollen tops (convex) need to be replaced and jointly could be responsible for your hassle. Don't confuse a leaking ca with one that has some real hard epoxy like material or glue (usually white) holding it in place.
