Hello, recently my Xerox 19-inch LCD Monitor screen just went black. When I power it up the blue power light will be solid for approx. 5 secs and the screen will light up greyish-black, then the screen loses all light and the power LED flashes. I think it's a communication problem or something? I'm trying to remove the rear case to check the inside, but I actually can't figure out how to remove the case! I removed the base and took out two screws from the back of the unit, but don't know where to go from here. I notice 4 female screw ends into the rear center of the monitor, but I'm not sure if they're a part of the removal or not. Thanks for any help you can give me!
I have the same problem with my monitor.
I don?t have the answer yet to resolve the problem.
if you want the first of us who find the resolution will advise the other.
I sent an email to Xerox to get the info to remove the cover without breaking it.

coolvegasmik, Sorry, to hear that your "cold cathode-fluorescent-lamp-back-lit-lcd-monitor" is not working. Did you hold and point a bright flashlight 1 inch from the lcd panel when it went to "black-screen"??? Did you see any icons on the "black-screen"?? Software NOT a fix for this "black screen of death" problem. You or electronics technician will need to open L91A and look for bad capacitors or bad soldering on the power supply printed circuit board. If unit is 4 to 6yrs old, just trade-in for new wide screen unit. See video clips of swollen bad capacitors at YOUTUBE when you search "lcd monitor repair". All lcd monitors (99%) use same basic design and principle of operation. Sometimes ccfl back-lit lcd monitors can be repaired for less than $6 in parts and monitor will work for 1 to 3 more years. 12fixlouie
This happened to me and I was able to fix it. I cracked it opened and found a bad capacitor, bought a replacement at Radio Shack and I'm back in business. Actually using it right now to post this.
most likely is the power supply in the monitor. gateway LCD has a building power supply in the monitor. it supplies 38W to the lamp. since there is no display, it tells me that there is no power to the monitor. if try another monitor and it works fine. then the problem is the monitor. (dispaly lamp is good for 17 Years- according to the tech spec.) but the power supply is pushing too much power. other vendors max power is apporximately 30W.
make sure there is nothing behind the monitor and has good air flow. Since there is no fan in the unit. it need to vent the hot air natually.
If you look on the back of the monitor it has the name of the manufacturer - which I googled and found this warranty information:

I too have an LCD Xerox - it worked fine for a while, then kept going blank and going onto standby. Unplugging and reconnecting from both pc and power seems to reset it. It hadn't happened for months but started again the other night when it occurred to me that I had just downloaded MS security updates - I've removed the ones that I downloaded just before it started happening again and the problem seems to be solved. Hope this helps someone.
Just tore mine apart so here is some help. You need to remove the two screws on the back of the case on the bottom. Then you remove the front cover it slides toward the top of the screen then lifts off. You can pry it off if that doesn't work.
If you want to seperate the screen from the back cover you then need to remove the swivel mount and the other two screws from the back cover.
