Hi, I read these boards a lot... very helpful.
Monitor has black screen, and the power light blinks very very rapidly. I connected a good working monitor up to the pc, and it works fine... not the computer. I pulled the power cable from the monitor, and replaced it with the one from the PWS.. the PWS works fine, sooo cable not bad.
I read somewhere this rapid blinking light was indicative of the monitor being in sleep mode. So I hooked up a good monitor, went into power management settings, and its set to "always on".
OS is Win XP Home SP2.
How do I get the monitor out of sleep mode?
I'm not sure if this is the solution, but something happened. I plugged in the monitor one last time before I was going to throw it out. I plugged in the power but left the VGA cable unplugged in hopes that I could get into the menu screen of the monitor itself. Well no amount of button pushing helped (but I did do it) but after about 20 minutes I came back to it and it was on. So I am really not sure if it was some button pushing or just a default for being plugged in (power) and no input (VGA). Now I'm off to apply the new driver.

That is a problem with the memory array in the monitor. If it is under warranty, don't even mess with it. Take it in. Otherwise open it up and exercise all the connectors on the logic board inside. That works about 30% of the time. If that does not fix it, then it is terminal. They are so cheap now that it doesn't even pay to try to get the repair parts. They will cost more than a new one.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
You need to try it on another PC, alos verify if the VGA cable is good. If nothing change, then you need to open it up, first thing to look for are the capacitors in the power supply. Look for cpas with bulging top/seal, see example of failed monitors here: http://s807.photobucket.com/home/budm/allalbums

candlelig840, Your "cold-cathode-fluorescent-lamp" back-lit lcd monitor may not be in sleep-mode!! However, it may be in "black screen" or "Blank n Black screen" mode. Spend an hour doing some reading in my fixya profile and read testimonials and follow the web links. Your monitor isn't any different than any other brand in it's basic design and operation!!! Again, read my and other LCD monitor tech's ("budmrtn" , "buddymc" ) for information on doing your own repair or to find out all your options you have when dealing with CCFL back-lit LCD panel that is now black and lifeless!! If you live in or near a large (>2 million) city, give a call to local TV/lcd repair shop and question them about black screen and what is the top cause of lcd monitor/ lcd tv black screen failures. If you need further assistance after you research your monitor's problem do another comment here on fixya and we will be glad to help you. Do not rate this response. If you do, you will break the link and not have option to do further comments back to this posting. 12fixlouie
cklein95, I should guess that the unit's "switch-mode-power-supply" is in full or partial shutdown mode. Check all cable connections. Then read a few of my longer responses to BLACK SCREEN lcd owners to find out all the options you have when faced with a LCD monitor that has failed prematurely. If unit not covered by warranty, you will need to decide if you are going to trade-up for wide-screen or contract out for repair or you will go on DIY repair quest. Follow the links to other sites listed in profile so that you will understand the no.1 cause of BLACK SCREEN. Do you know the lcd flashlight test? Do you know how to unsolder and solder parts on a printed circuit board. Do you know how those new energy efficient curlie-Q CFL light bulbs work? Hope this gets you started. 12fixlouie
Ok? first what you need to do is to hibernate your computer. You can do that by pressing the power button as long as you need for the computer to turn off. Then you turn your computer back on and press the power button ON THE MONITOR twice but you MUST do this really fast. Then what you need to do is to find a circuit breaker on the back of your computer. switch it to the off position then turn it back on. Then turn your computer on. This should fix your problem.
Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
If possible, try a friends monitor first. If it works, you can then change the sleep mode setting so that it won't come on again. If the other monitor does not work, the video card is probably defective.
