okay so out of the blue my monitor goes blank... worked perfectly for a good year or more... no problems what so ever...
I power off the monitor and power it back on and it will display for 2 seconds before it goes blank again... I also tried unplugging it for a day... and got a good 30 seconds out of it before it blacked out again...
the power light is green all the way through...
there is zero functionality from the menu and eAuto buttons while blank....
video card is fine... plugged an old crt monitor to replace it for now...
dvi connection is fine cause it still gets a picture for 2 seconds...
it's kinda like it goes into a no signal monitor sleep mode when there is signal...
I've tried taking out the dvi cord and booting the monitor with out connections... and it will say no signal for 2 seconds and black out...
acer driver support is no help... they only have windows vista drivers no xp...
Just got off the phone with Acer Suppport. This was after I sent an email to them, that suggested that I call. 8-/ annoying. So the guy on the phone says there is one thing that we can do before sending it in. Unplug it completely for the wall and computer. Hold the on/off button in for 30 secs. reconnect power and the computer. It worked for me

lumixgx, All you need to do is read my fixya profile for about an hour!! You will then know all you need to know about why your unit's "switch-mode-power-supply" /"CCFL inverter supply" circuit NEEDS SOME WORK DONE on it to fix it!!! Good luck with the repair. 12fixlouie
After two years, it will more likely to have failed caps in the power supply, common problems in ALL monitors these days, theymade them to fail after a couple years, does not matter what brand, see examples here: http://s807.photobucket.com/home/budm/allalbums
Post back what you find inside.
yetimonsta, Are you sure that the monitor is BLANK?? Or is it just BLACK? Or is it both BLANK and BLACK? Connect a known good monitor to your pc to prove that your pc is working correctly. What does your L90D+ do when connected to good pc. Have you done the flashlight test to evaluate the state of the "switch-mode-power-supply" when lcd panel goes black /blank?? View more of my profile on fixya and you will discover all the options you have open to you. 12fixlouie
You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Are you able to see a slight image on it at dusk and maybe with the
help of a flashlight. since your blue light stays on the video board,
may be okay.
It sounds like you have bad capacitors on your powerboard or possibly a burned out transistor on the inverter.
Only way to really tell is to open it up.
If you unplug the screen to video board ribbon, you may notice a different effect in the screen lighting.
There is a chance one of your bulbs is creating a problem
Should the screen happen to light up all white, then your power board
and inverter are okay and the problem may be in the video board.
If it looks pinkish or dark or flickers then the bulbs or a bulb may be the issue.
If it flashes on then goes off, it's in the power or inverter board.
This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps.
