Check the power supply section first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 VIEWSONIC 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.

Yea my ViewSonic VX710 takes and it will flash on for only 1 sec. then it stays off. if it is that bad capacitor thing can u just buy new power supply? You can email me if that is easier. Thanks


Yes, do look for caps with bulging tops as shown in my pictures, you should replace them in a set.

Viewsonic VX710 17" Flat Panel Display. It turns on and after 1 or 2 Seconds shuts the backlight off L.E.D. satys on but the backlight won't comeback on. No cap seems to be blown up.


Failed cap amy not show any sign of bulging or leaking, it can still have high ESR. You can also have components failure in the inverter circuits such as shorted inverter transformer driver transistors, open or short winding (DC Ohm test will not show shorted turn, need to use ringer test), I use SENCORE LC75 for testing, bad lamps or bad soldering works on the lamps. See http://s807.photobucket.com/home/budm/allalbums for some guide.

You may have bad transformers, need to be checked, DC Ohms meter may not be enough, need to use inductor tester (I use Sencore LC75). You can also have bad lamps (bad solder connections). The caps may not have any sign of bulging but can have high ESR, see some pictures here for guide: http://s807.photobucket.com/home/budm/allalbums
