Question about ViewSonic VX2235wm LCD Monitor
I have this 22" Widescreen ViewSonic monitor that appeared to have had it's backlight turned down so low you could barely see anything. When I pressed the "1" button to enter the menu, I could just make out the menu box and the highlighted options, everything else such as the text and even the webpage I had up were so dark I could barely see them or nothing at all depending on the angle of the montor sat at. (i.e. Much like how a Laptop screen looks with a bad Inverter Board)
Then, when I switched between monitors to look at a user manual and plugged the ViewSonic monitor back into the computer (I did this about two or three times), the screen on the ViewSonic was back to normal.
I left it on all night last night and it was still fine. Problem seemingly solved, but what would cause the monitor to become so dark?
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.
