Having problems with your ViewSonic VA712 17" LCD Monitor ?

My VA712 does not turn on, when supply button (mains) not from front panel, switch ON it shows blank screen (no sign of turn on) but when repeatedly switch ON & Off it Turns On & shows the display. What is possible fault?


Answers :

Bholesir, If unit covered by ViewSonic warranty, USE IT!!! The units "switch-mode-power-supply" is in need of service!! Unit WILL require inspection and repair of possible bad (poor quality soldering) soldering of electronic components to the prinded circuit cards and or need replacement of bad (poor quality) electrolytic filter capacitors on the unit's "switch-mode-power-supply"/"CCFL inverter circuit" that have failed!! Do a visit to YOUTUBE for "LCD monitor disassembly" and "LCD monitor repair" so you can familarize FYI with what is inside your monitor, and possibly make a decision to do a DIY repair or contract out the work to a local TV/LCD monitor repair shop. If your pocket is deep enough, maybe you will repair and buy a new unit, keeping VA712 as spare unit for a rainy day.
