My black screen with white writing and is non responsive

Since this morning, the screen on my iphone 4s randomly went black and the apple logo appeared, the some white writing on the top also appeared. I've tried pressing the lock and home button at the same time several times and charging it but I have had no luck. I've also tried connecting it to my itunes on my laptop but it doesn't respond at all and my laptop doesn't even recognise that its been plugged in.
I've tried to chat online to apple but they need my serial number which i can't get as my phone isn't working properly, I can't open the sim holder and my laptop is new and for some reason itunes doesn't have my iphone info on it unless its plugged in.
HELP
What should I do?
Thank you

Have you
tried to simply do a clean install of Mac OS X and
your other software? I normally find that this fixes
90%+ of all unexplained software related issues.
I could, but (a) I'm not convinced it's not related to the replacement logic board and thus a hardware issue, and (b) I can't see to do a clean install because it has no video signal

Black screen with white writing on boot - then nothing...

Ok, this is a long story, but here's the abridged version;
I have a mac mini - the old PPC version. It has just come back from being repaired - replacement logic board. However, repaired it is not. Every time i try to start it up, I get a brief white screen with grey apple logo as normal, and then a black screen with white writing on. The writing is exactly the same text as you can see in the console system log. It gets about a page-full through this, and then goes completely black. No video at all.
However, the machine is still working in there - I know this because I'm typing on it now via VNC. It is perfectly happy and all. It just does this weirdness start up and then no video.
My question is twofold:
1. The company that repaired it claims that it booted fine before they gave it back to me; however, it hasn't since I've had it back. Could the boot behaviour be some kind of diagnostic thing they left on my machine, or a mode they left it in. If so, how do I get rid of it?
2. Failing this, does it sound like my vidoe card packed up maybe?
Thoughts, solutions, etc., most welcome!

Imac start up goes to black screen with white writing

My imac on start up comes up with a black screen which has a lot of white writing on it. The mac then stops on this screen and to does nothing else. To re start the computer I have to un plug it. After doing this it will then work fine. this scenario happens about once a month.
Any help would be appreciated.
Thanks in advance.
Regards
Scott.

From reports I've read on here, a PRAM reset is likely to solve the problem:

Ipad has black screen with white bar

My ipad2's screen has gone blank. after leaving it uncharged for a good 18 hours. I switched it on to see a blank, black sceen with a white bar moving downwards accross the screen this fades to black.
I have tried charging it for a good 7 hours as I thought maybe the battery has run down and caused this.
I have also tried resetting by pressing the on/off and home button together for 10-15 secs but no luck.
My ipad still synches to my imac okay. I have restored it to factory settings. This didn't help the problem either.
This actually happened when first took the brand new ipad out of the box and tried turning it on for the first time. But it revived itsself after synching to my imac and being on charge for a few minutes. The support technition I spoke to at the time didnt really know why it did this but suggested it was a very low batterry issue. Although I am inclined to think its something else, now its happened again and charging does not seem to work.
Has anyone had the same problem? If so what did you do? Any suggestions on how to fix it would be gratefully recieved.
Thanks
P.S. I am running iOS 4.3.3 on my ipad. However its not an available option in the OS dropdown for this discussion. hmmm!

I Don't know if this will work for anyone else but just FYI - after loading 8.1 on my iPad it froze for several hours on the black screen with white Apple and progress bar underneath. It would not do anything. I thought I was doomed. I accidentay left it sitting overnight without plugging it Back into the charger. I meant to but got sidetracked and thought it was plugged in. During the night the battery was totally drained so this morning my iPad was dead. I plugged it into the charger and after a few minutes the battery icon came up showing it was charging. I gave it about 30 minutes and then turned it on and the new operating system came up. It looks like it might be ok now. I can't say I recommend this, but it worked for me.

HT1338 disk wont eject from my macbook pro and black screen with white letter text wont leave.

disk wont eject from my macbook pro. Displays black screen with white text. How do I remove or move on?

It sounds like you've experienced a "kernel panic".
This thread has some advice on how to deal with one.
If you need more advice, please explain what you mean by "disk won't eject from my macbook pro".

I don't know what's wrong with my 3GS. It only shows the black screen with white apple. Turning it on then off doesn't help.

I don't know what's wrong with my 3GS. It only shows the black screen with white apple. Home button and turning the phone off then on doesn't seem to do anything.

Thanks Lucas,
I've tried doing that with no results. Same screen keeps showing. Maybe it'd be more helpful if I told you a bit more info. My phone was randomly playing music, and the voice control would also suddenly start without me touching the phone. Then I let the battery die and started to recharge when on the screen it indicated to plug into my computer/iTunes, I tried to restore but was getting an error message (can't remember what it said now). Battery died and now my current issue of the black screen with white apple. I'd love to be able to restore my phone but now its not showing as a device on my iTunes. HELP! Any other suggestions?

Black screen with white apple logo won't go away! Help please.

Last night I turned theipod completeley off and restarted it. The black screen with the white apple logo came on and hasn't went of since.
I've tried everything I could find in the forums and on the support page.
iTunes will not recognize my ipod which has continously tried to start up again every 5 minutes.
I don't know what more to do, ANY help would be greatly appreciated.
Thanks
Dana

I did try that. When I do that the red slider bar to turn the ipod off doesn't come up.
Its still trying to reset itself but won't go any farther than the black screen with white apple.
Thanks

Black Screen with white text at startup (??)

Hello All:
I have a 2010 15" MacBook Pro, just got it in June. Had to send it in for a logic board replacement and now have it back. Everything works great except now instead of having the standard Apple greyish startup screen, I have a black screen with white text that scrolls through all of the startup stuff. I figure they changed some line on a plist somewhere so they could watch the startup and make sure everything was OK, then forgot to change it back.
Although I know it is good to know what's going on under the hood, I would rather it started up the regular way. Anyone know how to switch it back? I would call Apple, but would rather not sit on the phone for a long time for what I believe is probably a very simple fix. I did a search but couldn't find my problem listed....
Thanks everyone...

Kappy:
Thanks for the reply. I looked at the plist, but the -v was not there. Here is a copy of the plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel Flags</key>
<string></string>
</dict>
</plist>
At least I know what it is called now - a "verbose startup".
Again, thanks for the help. Learn something new every day.

Black screen with white circle every 5 seconds, after water damage

my ipod touch (3gen.32gb) had water damage 3 days ago. now as it dried, i connected it to itunes and restored, but it keeps showing black screen with white circle every 3-5 seconds. could this be a software problem or is it all because of water? i put it in recovery mode, and restored again, but it did not help, is there anything i could do to stop it ? thanks

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Macbook Pro boot shows black screen with white text cursor

Hello,
I have a MacBook Pro 7,1 MC374xx/A running Mavericks. My box has two internal hard drives in it. One had the Mac OS installed to it, and the other has absolutely nothing on it. I decided to give Boot Camp Assistant a try and chose the hard drive with nothing on it to install Windows on. I also had an external USB DVD drive attached with the Windows 7 installation disc on it.
So, next thing ya know, my Mac reboots and loads a black screen that says "Memory Overload." I take out the external USB drive and restart. Then it said, "No boot devices found." Now for whatever reason, it's just a black screen with a white text cursor.
What the heck happened?
I selected command R and confirmed that I installed Boot Camp on the right hard drive (the drive that did not contain my Mac OS). Then, I completely erased everything from the drive with Boot Camp on it. But still..black screen with white text cursor.
I have no Time Machine backups available so I'm forced to reinstall the OS. Any idea why this happened? It seems I must have attempted to install Boot Camp improperly. Any ideas or instructions on what to do now or how to install Boot Camp successfully on the Macbook Pro I own?
Earnestly,
Speck

Boot Camp- Windows installation boots to black screen with blinking cursor.

Frozen screen, black, screen with white whirly circle

my ipad seems frozen, black screen with white whirly circle, before this happened, kept going to the apple logo on the black screen

It might be time to restore your iPad. Recovery mode might be needed as well.
iPad: Unable to update or restore
Before you try recovery mode, connect the iPad to your computer and launch iTunes. Click on the iPad on the left side under devices. Then click on the summary tab. See if that works and if it does, click on Restore and try that way first.
iTunes: Backing up, updating and restoring iOS software
If that doesn't work, then you will probably have to resort to using recovery mode.

Black screen with white text on boot

Hi, When I boot my mac I see the apple logo for a few seconds. after that I see a black screen with white text then the computer starts up. What is this and how do I fix it?
Any help appreciated

Hi
This is "verbose mode", which is a boot-up mode used mostly for troubleshooting the boot process. Sometimes your system can get into that mode accidentally. Try this: boot up holding down cmd-opt-O-F (to get into Open Firmware). Type:
reset-nvram
reset-all
Your computer should restart; reboot it once more to see if you are now booting normally.

Black screen with white boxes?

I restarted my macbook about an hour ago, and it started up, then all I saw was a black screen with white boxes everywhere. I managed to login, but I can't see anything. Attached is what I see on my screen.

Hi maxh231,
Thanks for visiting Apple Support Communities.
If you are not seeing video on your MacBook display, try these troubleshooting steps first:
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
You can find the steps above and more information here:

TS1363 while updating my IOS to IOS 6 the updating process couldn't be completed for unknown reason and my iphone has nothing but a black screen with an apple and a meter that shows no progess. it completely froze!

When updating my IOS 5.1.1 to IOS 6 and after the download completed the updating of the iphone couldn't be completed for unknown error and the device froze and all i have now is a black screen with an apple and a meter that shows no progress I can't switch off my iphone or do anything!!!

Hi,
I had a similar problem last week with my nice shiny 3 week old iPhone 6. I noticed the Apple logo was on the screen, but it did not progress like a normal boot up. I restarted the phone, and it showed the Apple logo, then a red screen then cycled back to the logo and kept looping. I got the phone to the iTunes connection stage by keeping hold of the power button and the home button until the apple logo appeared then kept holding the home button. iTunes recognised the phone, and wanted to restore, but this was unsuccessful because the phone would keep looping to the red screen and iTunes failed. After loads of Apple support, I was told it was a hardware failure, and like you I live more than an hour away from the store. None the less, I made an appointment with the Genius bods, and they replaced the phone. They said they had never heard of the problem, but really, take a look at these forums and you will see that it is a common problem and I suspect they are keeping it under wraps...
My issue is that as a disappointed customer with faulty goods, why should i have to stick to an appointment to get it replaced? What other store would you have to do this?
The "Genius" didn't even want to see the phone powered up before offering a replacement... Oh, and it turned out they didn't have the exact same model as a replacement so they were going to send me out of the store empty handed.... I kicked off BIG time, and they very reluctantly gave me a phone from the sales stock, rather than the repairs stock..
Not a happy Apple customer anymore, and I feel the more people who know about the lack of service and customer care the better. They need to get off there high horse and join the real world!
