Question about ViewSonic VG700b 17" LCD Monitor
What is the cause, and possibly the solution, if any to this problem? i am pretty adept and can repair this if i only knew where to look. or am i wasting my time
Usually a completely white screen is an indication that there is no video signal being fed to the panel from the controller. For instance, if you take a working LCD monitor and just disconnect the video cable that goes to the LCD panel from the mainboard, it will turn on and off just fine, but it will light up bright white.
So, there seems to be an issue getting the video signal from your logic board to the panel. This can be caused by a bad cable, a loose connection, a bent and/or shorted pin (from plugging it in wrong), a bad logic controller chip, or a blown fuse/component on the LCD's circuit panel (PCB that runs across the top of the back of the LCD panel.)
Hope this help!
