Black screen, red light flashing

I was downloading an app when a screen message told me to restart to continue installation. I pressed the Off button but now, despite pressing the start button, the phone will not come alive, although it was recently charged. There is just a black screen and the small red light flashes occasionally.

Hi HarryTyrrell
Welcome to BlackBerry Support Community Forums
Pressing the Off Button is not the Correct way to restart our BlackBerry device, please perform a Battery Pull Restart like this While Device is Powered On remove the Battery wait for a min. then re-insert it back wait till the device take a long Reboot. See if that helps.
If not then try Starting your device On Safe Mode and on Safe Mode Uninstall the Application your Downloaded recently or which you think is responsible for that.

  • My BB won't turn on the red light flashes and the key's light up

    Hi
    I have read all posts relating to my problem, but one thing my BB won't do is resgister on my computer.  The phone will not turn on, has the red light flashing and the keys light up, but the screen will not come on.  I have tried taking the battery out, charging it all night, all the recommended/ideas from this sight, but no joy.  I have only had this phone since July last year.  I haven't been able to try updating phone etc as it won't register on my or my husbands computer please help
    Louise

    Hi,
    The way you presented it made me think it had just happened.
    So you have had the phone since July has it ever worked?
    Most likely you are missing some or all of your device OS and you'll need to reload the device.
    Because the phone can't generate enough signal you will have to "force detect it". I've attached the link below. If you want to proceed I'll need what version of Device OS and what version of desktop manager software.
    Thanks,

    Help! Turned my Q10 off yesterday to reset as emails not getting through. Now won't turn back on - just a little red light flashing at top right of device in a specific pattern. Nightmare-any ideas??

    Connect your Q10 to the known working OEM wall outlet charger.
    After being connected several minutes, LEAVE it connected and remove the battery a minute, and reinsert... does it reboot?

    trying to turn on my HP compaq d330 but red light flashing and beeping and nothing comes on help a newbie please
    This question was solved.

    You can try removing and reseating the memory and see if that works.
    If that doesn't work, remove all but one memory module (if the PC has more than one), and see if the PC runs normally with one memory chip. If it beeps, remove and replace with the memory you removed and keep doing that until you find the bad memory chip.

  • Blackberry 8100/8110 Red Light Flashing

    It seems this is a common problem.
    I loaded my Pearl 8110 or 8100 with a sh**load of music, pics & videos.
    when i went to access them, play them or slideshow them, I noticed it took forever...attempting to ease the memory load on my phone, i started deleting, from the phone itself (not while connected via USB), songs, pictures, folders thereof, etc.
    then it died.
    and it wouldnt re-start. pulled the battery, tried to sync it, tried to update, tried everything...the computer WONT read the phone...the update keeps getting stuck on re-initailization and when i finally cancel, it says "UNABLE TO UPDATE USING A MULTI-STAGE UPLOAD" or something like that.  it's almost as if the usb port got fried...it momentarily connects when the red light flashes on, then disconnects when the red light flashes off.
    i've read thru 3-4 pages of posts on this without any hope in sight.
    is it futile?  or is there something i havent tried?

  • HP desktop won't start, red light flashing and beeping, loud fan

    Yesterday it was working just fine. I turned it off for the night and when I tried to turn it on this morning, a red light was flashing and beeping as well as the fan making a loud humming noise. I've read the the beeping and flashing means something. I didn't keep track of the number of flashes and beeps though. After the beeping and flashing I turned the computer off then back on. This time there was no red light, flashing, or beeping. Nothing appeared on the monitor either. After about 10-20 seconds of it being on, the fan started to hum really loudly again.
    It's an HP Compaq dc7900. I've only had it for about 3 months and it was fine up until now.
    Any help? Thanks.

    Hi
    I'v checked the specs for your HP and Acer machines and yes it will be fine to cross over RAM modules they are identical in speed and architecture . Please don't forget the last post about removing the sources of power before you go inside the PC to check RAM . Other thing is if your HP has more than one RAM module remove only one stick first and try to boot . If it still won't boot with that module take that one out and try to boot from the other before you look to swap over modules from Acer machine . Don't forget to re connect your monitor to see if you get display with one / two etc modules . Post me back your findings

    iPad 2 has a black screen which lights up to a grey black screen when I press the power or home button but I dont see the apple logo. The battery is fully charged and when I plug it in to my computer, I can use iTunes to do everythng except backup the iPad since its passcode locked. Please help me resolve this problem.

    Yup! I've been there! You just have to double-tap the screen with three fingers and the zoom should go back. You have to turn off the feature in Settings>Accessibility>Zoom>and turn the switch off so this won't happen again when you double-triple tap.

  • Phone wont turn on and red light flashing 5 times with pause/s in between

    i was charging my phone, after 30 minutes i unpluged the plug from the mains and typed in my password. from there on the phone went completely blank and all i was seeing was a red light flashing. I charged the phone for 12 hours and now i cant see the red light anymore. The only time i see the red light flashing is when i use the usb or the phone charger. At the moment the phone is completely blank i cant switch it on. Also ive tried using the usb which didnt help my laptop doesnt recognise it neither does the desktop manager.

    Hi and Welcome to the Community!
    Without the use of the charging port, tests will be more difficult, and results less definitive. Nevertheless...this sequence is needed:
    Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem. Note please that "known good" and "new" are not necessarily the same thing...while rare, a new battery certainly can be defective. The best (and, btw, least costly) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
    If the result is that your BB is the issue, then you will need to seek out a local (to you) shop with a qualified BB hardware technician to give you a proper evaluation and estimate. If you remain in warranty, you could instead seek support under those terms (assuming your warranty is not void).
    Good luck and let us know!

    Reset the SMC and then test: http://support.apple.com/kb/HT3964
    Otherwise as the other folks indicated, its time for diagnostics / service. Make an appointment with a Mac Genius at an Apple store, contact AppleCare via phone, or contact an Apple Authorized Service Provider for assistance.

  • Desktop Computer dc5750 shuts down and red light flashes on front of computer and won't start at all

    I have a DC5750 HP Compaq Computer it is 6 years old, but I have 4GB Ram, Nvidia GS8400 Graphics Card, two one TB Hard Drives. While I tried to re-installed my operating systems it all of a sudden shut down not once but twice, I opened up the side of the computer and found that it was hotter then normal. I let it sit for a while thinking it maybe over heating after hooking it back up I turned it on again nothing happened except a beeping noise and red lights flashing on the front. Can this be fixed as money is an issue.
    Thanks

  • Won't boot only red light flashing

    My BB Z10 unable to boot or charge once the battery all used up.
    When I plug to wall or PC, only red light flashing.
    Sent for repair twice, just return with a full charged battery device.
    Once I used all the battery it won't charge.
    I have to recharge the battery before it's all gone,
    Or you have to follow the steps to reinstall the OS make it charge again.
    Does it make sense? Will you accept that?
    Means if I did not charge my Z10 before battery all gone, I have to do the OS recovery and ALL THE DATA GONE.

    Hey panda1111,
    Welcome to the BlackBerry Support Community Forums.
    Thanks for the question.
    Follow the steps below to try and bring the BlackBerry Z10 back to life:
    Ensure that BlackBerry Link is installed on the PC or Mac OS
    Ensure the computer has an internet connection.
    Launch the BlackBerry Link Software.
    Note: A backup of the BlackBerry device should be tried before a reload.
    Turn off the BlackBerry device. Make sure there are no flashing LEDs and that the LCD is not still being lit by the backlight. If there are any flashing LEDs, hold the power button for 15 seconds until the LEDs stop.
    Connect the BlackBerry device to the computer.
    When prompted with Cannot communicate with device, click Restore and then click yes allow the update to be downloaded and installed on the BlackBerry device.
    If the restore button is not seen press the vertical dots in the lower right corner of BlackBerry Link and select disconnected device.  Highlight the disconnected device you are working with and attempt steps 4 to 6 again.
    If the issue still persists, then I suggest contacting your network service provider for repair options. 
    Let me know if you have any more questions.
    Cheers.

  • P.B.R. meaning it Powers on, goes to Black screen, then Red light flashes....?

    ill tell you word for word what happen and see if you could help me out. i was listening to music one night with my phone on the charger, and fell asleep. when i woke up in the morning the hour glass would rotate, the screen would go black and a red light will flash. it would repeatedly do this. how do i fix this? or is there any fixing?

    Your battery is dead.
    Leave the device to charge 2-3 hours, and then, still connected to the USB cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage).
    If it doesn't boot--try using a wall outlet charger if you are not. If you are connected via USB to the PC, make certain that you have Desktop Manager (or the USB device drivers) installed, which you can download below.
    Here are some good charging tips, please read and you'll see that many of them will apply to you.
