Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://www.badcaps.net http://en.wikipedia.org/wiki/Capacitor_plague
craigcorbin, Could be "switch-mode-power-supply"/CCFL "INVERTER" supply that is flakey or better still has a "thermal" problem. Thermal problems arise from temperature cycling of the parts on the circuit board that heat-up due to their need to dissapate energy in the form of heat, and then return to room temp when unit is turned off. Hot = expand, cold=contract After enough cycles occur on an already poorly soldered connection you will end up with a Thermally Intermittant connection which will only get worse due to oxidation of the now exposed RAW METALS to the surounding atmosphere. Sombody will need to open unit and inspect the board(s) for this type of fault. 12fixlouie
I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.
Actually the common problem of viewsonic LCD monitor is bad electrolytic capacitor at primary, secondary & inverter area, if your lcd using power adaptor test the voltage out, use analog or digital tester range 50v dc, if the voltage out is accurate dont be sure to your adaptor working good, open it and find bad electrolytic capacitor inside. That is common problem of viewsonic LCD monitor could cause of display flashing then back to black after few seconds. Suspect inverter area lastly mainboard.
hi, first run the system in safe mode, if that works than u will have to look in for driver problems/settings, sometimes uninstalling the monitor & display driver then reinstalling it back will change the settings to default, try it, let me know
