Hello,
Boy, am I glad I found this site before I spend boo-koo bucks on a new monitor.
I walked away and my monitor went into screen-saver mode after 15 minutes as it's set to do. I came back again and the screen was blank, dark.
I usually just have to move my mouse a bit to get my screen to show the site I was on.
This time I moved my mouse and all I saw on the blank screen was a millionth of a second flick. Moved mouse again, same thing. Almost like the screen wants to turn off or on but doesn't.
I've moved the screen to other desktops in the house and it's the same thing. I've double and triple checked all connections. All the green lights on the front seem to be just fine but I get no picture, only a black screen and a very slight/hardly noticeable flicker on the screen when I move my mouse.
Turning off and on, rebooting, shutting down machine for a couple of hours and moving screen to other computers doesn't change anything.
Have any ideas before I go plunk down money on a new screen?
Thank you all ever so much for being here for us not-so-smart-when-it-comes-to-computers people.

I have an E152FP and I was having the exact same problem...my fix was just to turn down the brightness below 60 and I have not had a problem since. Hope this helps...
I chased around the unit, disconnected the LCD for the controller and the back lights. I found that the green led stayed on with these disconnected.
Following this I discovered that the 1000uF 16V cap had swelled (been damaged). These are near the two diodes on a heat sync. I replaced both 1000uF 16V caps and the 470uF 16V.
And now it works, I even get the Dell Genesis logo when applying power to the unit.

Hello,
this looks like the backlight has gone in your monitor, to test this connect this monitor to your pc and wait for green light. get a torch and shine it into the screen (really close up) you might see the log in screen.
To fix would probably cost more than the actual monitor is worth, would suggest going online and getting a cheap replacement, loads of them are listed on online auction sites.
Probably the color temperature setting or some other color settings - since you didn't specify your monitor's brand and model, it's hard to guess. Anyway, most monitors have a "Reset to factory defaults" feature - you may want to make use of this...
The VX900 has 2 different version of the unit. One version has an external power supply and the other has internal power supply. Since you said you changed the power cord I would guess you have the internal power supply version. The issue you have is caused by the capacitors on the power supply board have overheated and blown out. This is a common problem on many LCD monitors after a few years of use. If you open the back of your monitor and look at the supply board you should see the bulging capacitors. Check our web page at: www.ccl-la.com for Pictures and examples of what to look for and what you need to get to do the repair. If you have any questions let us know on our web site and we will be glad to help you get going again.
I hope this helps, If so please rate our solution.
Inverter has probably gone out. You can replace them for around 15 bucks. You'll have to remove the front plastic bezel from the lcd, and then right below the lcd you'll see the inverter. Just check to see if there are any part numbers on the inverter and search for it on eBay.
Your backlight inverter inside the monitor is out. If you are
comfortable soldering you can repair it yourself. We have a step by
step repair guide on our web site at: www.ccl-la.com/LCDrepair5.htm
+++++++++++++++++++++++++++++++++++++++++++ This is the same problem with my 4 VG800 Monitors, you should be able to find the correct capacitor on your monitors by following the same procedure, I'm sure the boards are similar. Just get the correct value capacitor and try it in parallel with the initial filter capacitors right after the DC power in. +++++++++++++++++++++++++++++++++++++++++++
Alright, I had 4 VG800 monitors with the exact same problem. The front
led is blinky OR constant reddish/orangish OR picture is white with
colored vertical lines OR no picture with whistling from the back of
the monitor and backlights illuminated. All problems have the same
solution. You need to disassemble the monitor (2 screws on the back,
remove lower front button panel, remove 2 screws holding panel in and
remove speakers, then remove panel and unplug speakers. Now remove
lots of tape and screws from the cover in the center of the monitor).
Now that you've exposed the amplifier board and the VGA to LVDS board,
you want to look for the pair of 25V 100microfarad capacitors that are
nearby the DC power in (they are right next to the black "100"
inductor). Desolder the capacitor farthest from the DC jack and
replace with an electrolytic with the same specifications. If you want
to check that this is the correct solution please put the new capacitor
(WATCH THE POLARITY) in parallel with the capacitor there want watch
the front panel indicator go green and the monitor work properly.
I'll be posting and Instructable entry in the next few days on the
process, watch for the username Waterppk on the website
