23" HD display went black. What now?

HELP!
Is there a DIY diagnostic protocol for a dead 23" Apple Cinema HD Display (2 yrs old)? I use my system everyday in my work, so, I've got to be sure that packing this giant thing up and sending it off for weeks (?) is absolutely the LAST RESORT before I do it.
Backstory: Thunder storms in the area last Thurs. So I shut down everything and unplugged. No nearby lightning strikes that I know of, but, when I powered back on - the monitor was black. Nothing. No flicker. No grey screen. Not even the little "I'm here but not awake" light in the front. No matter what I did (restart, replug,etc) Nothing. Everything else was fine. Called Apple support. All they could do was run me through a PRAM reset, then, wish me luck at the local re-seller. Since then, I've connected the CPU to another slightly older Apple display (sans power brick) and all was fine with the CPU. So, it seems like the problem is either the monitor itself or the power brick (A1097). Quite a big price spread to risk replacing the wrong one. What can I do to test either one myself before sending off or buying new? Fast!
Thanks,

Wow, BSteely, thanks for stepping up.
No, I don't know of another ACD owner nearby. The local Apple reseller didn't seem eager to give me any names either. I decided to order a power brick "blind" from DV Warehouse knowing that the most I'd be out would be about $40 (or 25% re-stocking fee) if I had to return the adapter. I'd also know at that point that I'd have to buy a new monitor. Good that the 23" HD price has just come down, though.
Do you know if an electronic meter check thing would work on the power brick?

HT4623 I installed ios7 on my iPad 2 yesterday, this morning it wouldn't open the weather channel app. I thought maybe I should power it down. When I held down on the power button the screen went black and now it won't do anything. What do I do now?

Try a reset: Press and hold both Sleep/Wake and Home buttons until the Apple logo appears.

My phone just went black and now it won't turn on or charge

Try this First... No Data will be Lost...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...

Release the Buttons...

Hi alicia243,
Thanks for visiting Apple Support Communities.
If your iPhone wont power on, I recommend going through these steps first:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Best,
Jeremy

See Ogelthorpe's link:
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

TS3274 I have a new iPad mini w/retina display. Recently, the screen flickered with red lines across the entire screen. Anyway, the screen eventually went black. Now it does't work. Anyone have any suggestions?

My screen just went haywire. The screen flickered with red strips vertically. I thought it was part of the game I was operating until the screen went black and a white strip illiminated at the top. I tried turning teh system off, but it would not allow me to turn it off. After about 5 minutes, I was able to turn it off. Anyone have this occur? The Ipad mini appears to be ok now.

I Also have this problem!!
In my situation, the screen simply started exhibiting the same symptoms a few weeks ago (early February) for no apparent reason. At first I thought the screen was dead, but discovered the heat solution by accident. Now I turn it on and keep it from going to sleep until I go to bed. Thank goodness the battery is still awesome on this thing.
I bought it new and still has the original screen, I keep it at home (never below 62 degrees). Coincidentally, this happened a day or two after the expiration of the warranty!! Any help figuring this one out would be eternally appreciated.

HT201263 My phone jammed while opening an app, the screen went black, and now wont turn on. I've tried forcing a restore with no luck, what do I do now?

My phone has been fine, then yesterday I tried to open an app, a phone call came through at the same time, and the screen went blank and now is unresponsive. I have tried holding the lock and home button, I have tried holding the home button while connecting to my laptop but sadly to no avail. What do I do now?

This was the third Restore I've attempted today.... 'm not sure what all I did including unplugging and plugging it back in, and messing with tryign to select my phone vs. my husbands but it starting moving again. It's now attempting to "back up" from ICloud... we'll see. Thanks

Display went black

Was using my macbook as normal, then poof screen went black thought battery was dead but it is 65% also noticed on restarting I can faintly see my log in screen at the right angle. Any opinions as to what is wrong. Of course my apple protection plan just ended in october so I'm sure it will cost me.

This happened to mine... it is most likely your display inverter you can hook it up a external monitor to check in that case the other monitor would work.... you can either replace it your self but it is a very hard job or you can take it to the mac genius. I did both i replaced it myself but since the piece was refurbished it messed up again like a month later (the piece costed about 75) so then i took it to them i got it fixed for 118 and that its no problems so far and they were very nice.
I suggest just taking it to the mach store

Ibook display went black

I have an ibook g3 800.
I am experiencing the display to be back when I turn on the ibook.
I had the logicboard replaced under the logicbord recall.
I am not sure what might have caused the display to go black. It was working a few a months ago and then it went black. I know the HD spins up, because I can hear. I tested the computer in target mode and know the HD mounts
I am able to get the computer to show me any display when connected into the apple VGA (RGB) Cable.
Is a key combination that I need to use to get the ibook to work off an external display?

Maybe the answer is somewhere in here:

I have a 30 inch monitor on my mac pro tower that just went black, what do I do to fix it?

I have a 30 inch monitor on my mac pro tower that just went black, how can I get it back on?

He's asking what are those things you are using, i.e., ...
What video card are you using?
What version of OSX are you using?
What model of mac pro are you using (e.g., 2010 Mac Pro is 5,1).
And also,
Try smc and pram reset.
And see if the monitor lites up if you boot in safe mode.
It is possible your monitor simply failed -- its power supply or something else.

Hi! I downloaded a plug-in that slowed Firefox, even after I removed it. I reset Firefox, during reset my computer went black. Now it won't open. Help!

I downloaded a plug-in (add-on) from Facebook onto my toolbar and it made my entire computer run slowly. I disabled the add-on, removed the toolbar, and everything was still super slow. I went to troubleshooting and hit reset firefox. It was in the process of resetting and my screen went black. I thought it was just the screensaver but after pressing the space bar, screen did not return. I did a hard exit on my Mac and restarted my computer. On my desktop there is now a folder that says "Old Firefox Data". When I try to open firefox I get a message that says "your firefox profile cannot be loaded. It may be missing or inaccessible. I've tried to reinstall firefox as well, only to have the same result. Help!

Do you have JSON backups that Firefox keeps in the bookmarkbackups folder?
If you use the Time Machine then you can try to restore the places.sqlite file.
