This is a very common problem with this model after a few years of use. This problem is caused by a failure of the capacitors in the power supply board hat powers up the back lights in the monitor. When the back lights don't power up you get no display on the screen. Here is a link to a repair guide for that model that shows how to open the unit and what to look for and replace to repair the monitor.
Black screens or no pictures are usually caused by a failure in the back light power supply. Many times the monitor is working but with the back lights not turning on you can't see the display. Here is a link to a repair guide that will show you how to open the unit and what to look for and replace to rebuild the power supply and bring the unit back to life.
I've been having the same problems with my Viewsonic.I plug it in and the blue light blinks but there's no picture it's just a black screen.I do know if Viewsonic doesn't repair my monitor I'll never buy anything from them again.I have the LCD Viewsonic 22' Vx2235wm monitor.
Does anyone have any idea what could be wrong with mine?I've bought a new video cable & video card but the monitor still does the same thing?Thanks
avintagedish, Possible problem w/unit power supply. Go trade it in on new a new wide screen so the electronics technician in the repair area of the store can (with a little luck) put less than $10 in parts into your unit and maybe have a nice VX2235WM to give to his 10 year old kid to play games on. I sure hope you have a valid warranty!! You should verify that VX2235WM does same at KNOWN GOOD pc!!! Swap-in a KNOWN GOOD monitor to prove pc is OK!!! Read my FIXYA profile and learn "flashlight test" for "rude an crude" test of "switch-mode-power-supply" status. Follow the links you find there to other web sites for more info. Check to see if ViewSonic has a cash+old swapout for factory refurbished unit for premature failed units! I'm lmistyrel over on aim. and 12fixlouie on FIXYA good luck in your quest to fix unit. It can be fixed. Just do your research FIRST! So you don't get ROOKED if you contract out the work. Read, read, and read some more!! Visit YOUTUBE for video clips of LCD monitor repair and disassembly. FYI.
Bye for now.
Don't let the computer turn the monitor off. Go into control panel and click on power option. don't let the computer turn anything off and disable hibernation if on. go to screen saver and have it come on in about 30 mins.
I've not seen this problem on a ViewSonic but have on a Dell flat screen. The fix was the obvious one: the power connection on the back of the monitor was loose -- have you checked this. Also if the power cord is too tight it could be the problem. Other then this, it sounds like a short inside the monitor.
