Question about ViewSonic VA720 17" LCD Flat Panel Monitor
If i turn it on the picture comes on and looks great for about 10 seconds then goes off. If i turn off and back on i get picture and goes out again. Power never goes out is still green. I just trying to find trouble shooting info on it and seems like a long chore. Any ideas let me know thanks.
It is likely that the backlight inverter is failing. This is a very common problem. The inverter is one of the two ciruit boards inside the monitor. If you can still see a very, very faint image on the monitor, then the backlights are not coming on. The inverter is easily replaced by removing the monitor's back cover, then removing the RF shield over the inverter board (on the left side of the monitor's back), and then finally removing the inverter. A replacement part will cost about $60 as of the time of this writing. The new board will plug right into the 3 cables and is mounted with two screws.

One of the backlight converters might be failing. Check the fuses on the converter, or ask a technician to do it for you. Good luck
