I have a ViewSonic A57f. On the front of the monitor are 4 buttons:
“1” (or Menu/Page)
“2” (or Select/Exit)
The 1 and the Up arrow buttons work, but the Down and the 2 buttons do not. This is keeping me from adjusting the screen proportions or position, so I am stuck with a perfectly centered 1280x1024 view with about a half of an inch of nothing on all 4 sides.
It’s especially weird since the working/non-working buttons alternate, as in: Working, Non-Working, Working, Non-Working
Anybody have any experience in fixing these types of buttons, or know what could be causing it? Any suggestions?
