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

2-This step is very important. The collar has two parts snapped in together, with 3 snap in each side. Carefully use small flat screw driver to take off the back side of collar

Look for bad caps in the power supply first, see example of failed VIEWSONIC monitors due to bad caps here: http://s807.photobucket.com/home/budm/allalbums
