My blackberry won't turn on.

The blinking red lights are an indication that your phone battery is drained and needs to be charged before the phone can switch on. There's nothing wrong with your phone.

this happened to me, it needs charging make sure the lead has the blackberry symbol facing up....

this is a software problem, download blackberry desktop manager from blackerry site, remove battery and connect phone, software will e downloaded ,insert battery when software displays powering on.
try this and post result

A red light on a blackberry means the battery is flat. (Requires re-charging)
If you are confident your battery is FULLY charged and your charger is working then you may need to take your handset to a repair shop.

Try charging up the battery whilst in the handset. Let it charge for 30 mins then try and switch it on.

Remember...Blackberry handsets take longer than most to start up.

I have the same problem with my Blackberry 8120, died this morning, will not switch on, no red light, no charging light, completely dead... my computer does not recognise the blackberry at all so cant install any new software.. plus I need to recover all the information that is on the handheld... please help if you can....

I just called Verizon Wireless who said that the phone may need to be charged completely for a few hours. Try taking the battery out and putting it back on as well.

Charge your Supertooth one via the car charger or by attaching a usb/mini usb cable to your computer usb port. Need to charge for 4-10 hrs. Indicator light glows red (needs charging), orange (charging) or green (charged)
Power on: Press green button for 1 second. Indicator light blinks blue. A beep will be heard
Power off: Press green button for 1 second. Indicator light turns red. A beep will be heard

To pair with your mobile phone:
1. Press green button on Supertooth for 5 secs until indicator light blinks red/blue 2. Access bluetooth menu on your phone. Turn bluetooth on. Execute a bluetooth search. 3. Select ST ONE from list 4. When phone requests password enter 0000 and press OK 5. The handsfree kit is now ready for use 6. Clip Supertooth on sun visor of your car so that the microphone and control buttons are directed towards you. 
To make a call: Dial number on phone. Supertooth will automatically connect. Indicator light is steady blue during call
To end a call: Press red button for 1 second
To answer a call: Press green button for 1 second. The bluetooth indicator will turn a steady blue.
To increase/decrease volume. Press volume buttons repeatedly up or down. They are situated between red and green buttons.
Hope this helps.

this happened with my first blackberry and it never turned back on guess what softwar glitch it was never goig to work again so i got a new one the second one started having issues within a month and eventually got to the point where i couldnt wifi it would turn off on me for no reason tell me i had no service when i should have hang up on people freeze and simply sucked took it in to get it fixed guess what another software glitch that one went to blackberry heaven and i got another one this one is only 1 month old has all updated software and hey guess what no issues at all i suppose every phone has bugs in it to begin with look the aple iphone blew up when it first came out until they fixed the issues with it.

if your on a plan ur under warranty with blackberry take it back and there policy basically replaces the phone.

good luck

The red light indicates its charging.  My guess is that the battery is dead and will nto hold a charge.  This is an older model phone and the lives on the batteries is 1-3 years at most.
