Black screen The monitor is a viewsonic VX2235wm. It powers up but it has a black screen. I connected the PC to another monitor and it worked fine. The Viewsonic monitor worked fine when I cut it off and when I restarted the PC the next day it never came up, just a black screen

This really sounds like you have a power supply board that is having problems with the filter capacitors which are causing it to not start up correctly. Here is a like to a repair guide including video instructions showing how to open and repair the monitor.

Part one of the video guide:

Hello,

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.

Here is part one of the three part video repair guide posted at the above link:

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.

sounds like a burnt or a cold solder around the TRANSFORMER section of the power supply , I suggets if your handy w/ tools to open the monitor and inspect the PC BOARD for any burnt or cold solder THAT not making the connection , hope it helps AJ

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.

Hope this helps

hello do you still have the monitor maybe i can trade you something for it i could use the parts to fix a unit i have lmk thanks
