We recently had a power surge at my company when a storm rolled through. No lighting just a surge. The Monitor has a blue on switch witch blinks but the screen stays black. I've swapped out the monitor with another and that one was fine. I also tryed this monitor on another PC and it still didn't work.
Could have blown some capacitors inside the monitor. I just fixed one today that had no power, the blue ring around the power button didn't even light up when plugged in. I open it and found 3 bulgingcapacitors on the power/inverter board. They were all 25V 470uF rated capacitors. Went to radioshack and found 2 35V 470uf, got them at $1.29 each, then I found 1 50V 470uF out of a dc car power adapter for an ipod, it was as close as I could find. Replaced the 3 broken/bulging ones with the new/salvaged ones, put it back together, plugged it in and the blue light came on when I pushed the power button. Plugged it in to my laptop with vga cable, and it works great.

It depends on what type of connection you are using. If you are using a VGA (analog) cable then you need to select that mode on your monitor menu. If you are using a DVI (digital) cable then you need to choose that mode on you monitor menu.
If this happened after a storm, the monitor may have been subjected to a power surge, which unfortunately might have killed it.
If you have another monitor (or a friend who has one) try plugging that other monitor into your computer. If the second monitor works, yours will need to be replaced as the input was probably destroyed by the power surge.
If the second monitor also doesn't work, there may be a problem with your computer, most likely with the power supply (this is the part most often damaged by a power surge). You may want to have it examined by a professional computer repair person at that point.
Hi! Most modern monitors have on/off switches that are NOT actual power controlling devices. (i.e. they simply tell an IC chip to cut power to the display section while leaving the rest of the power supply energized.) In the earlier monitors, when you flipped that power switch, you actually cut AC power to the whole unit. Now, with today's faster computers, LCD and plasma displays, instant-on is the norm. Regardless if the button is physically damaged(usually pressed too hard) or the circuit is defective, unless you are a tech you'll have to take the unit in for repair. Is the monitor under any type of warranty? Was there a storm recently? Do you use a surge protector? If the display was damaged at all by the storm, there is a very good chance you'll be covered by the surge protector warranty.(that's what you paid for)---hope I was of assistance---Rick
I'll hope for the best and assume the simple fix first. Check the plug at the back of the monitor to insure it wasn't pulled out slightly. Sometimes, moving something around can cuse the plug to lose proper connection.
Also, check the power source to insure that you have power to the unit. We had a lightening storm recently and the power strip surge protector did it's job. I turned it back on and everything powered up again.
I hope this helps... Good luck!
Be sure that the power cable and the video cable are plugged into your monitor, the power cable is plugged into a good outlet, and the video cable is plugged into your computer. It's possible that you simply have a loose cable.
If everything is installed correctly, and if the screen is completely blank (no "cable disconnected" or "test mode" messages), then it sounds like your monitor is simply dead. Since there was a heavy wind storm recently, it was probably hit by a power surge. If you don't already, I recommend that you use a surge protector for all digital equipment.
I have a Xerox XA7-19i. It has the same problem as described by many
others - intermittent fault with the display that manifests as a white
screen when the monitor is first switched on. After a few trys of
switching on and off, the monitor works fine until left off for a few
hours. Recently, the problem deteriorated to no light from the panel,
and a flashing blue power light.
I HAVE SUCCESSFULLY REPAIRED MY MONITOR:
I opened up my monitor and removed the power supply board. I de-soldered every electrolytic capacitor, and replaced them with new capacitors of the same uF and voltage rating. I put the monitor back together again and switched it on - it worked perfectly!
- these monitors have been built using sub-standard / under-rated
electrolytic capacitors. After two years of use, the power supply board
was unable to supply enough power to the logic board and backlight,
causing the above-mentioned problems.
The repair cost me ~ GBP
15 (USD $30). It is not a difficult fix, but one only to be attempted
if you have electronics knowledge. Careful, kids! you'd be playing with
the power supply of a mains AC electronic device. That stuff can kill.
- I saved myself (and the environment) from having to throw out a
monitor and buy a new one. If you have a faulty xerox monitor and are
getting no love from Xerox customer support, find an electronics geek
and ask them to replace the electrolytic capacitors on the power supply
board. (but be careful to get the right kind of capacitors, and to get
the capacitor polarity correct. If you have any doubt as to you ability
to do this, don't bother trying!).
Your system was not affected because the PSU can prevent power surges. Your monitor's backlight has went out due to surges in electricity to your monitor. Unfortunately, you can not replace the backlight. I would suggest you buy a new monitor. 19" LCD Monitors has have went down dramatically in the past month.
