My blackberry pearls radio shuts off and when i turn it back on it stays on for about 10 seconds then shuts off. i dont know what to do.

Hi,

This is unfortunately a known issue with the Pearl. There are a couple reasons to why this happens. If your battery is defective, then your phone will sporadically believe that your phone is low on battery (even when its not), this will cause your phone to kick the radio off by itself--even every 5 minutes. Try cleaning the battery contacts or even try a new battery. Another reason is a faulty OS, if the battery replacement doesn't work, then the problem is with your OS and will have to be re-installed. I know this sounds like a hassle, but its a known issue and it should take care of your problems.

Below is the procedure :

This would be a long procedure.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I would first try updating the OS.

Try this:
Options> Mobile Network> now press the BB menu key> Diagnostics> Now press the BB menu key again Run

When there is no signal around ur blackberry will shut off the radio instead of constantly searching for one which really kills battery power just make sure you arent in a real signal dead area and you should be fine to turn it back on just go to manage connections and click it back on,if this is not the problem then there might be some problem with ur phone.

Try taking battery out and putting it back in - have had a couple of problems with my own blackberry and this is advice I was given, and it worked! Might be worth a try anyway.

If it was spotty reception, I'd suggest the antenna may have been damaged when dropped. They do get damaged.
But systemic, timed 16 second bursts?
In Settings, when is your phone configured to 'go to sleep'? After how long a period of inactivity?
It may not be considering the radio signal is be sufficient activity to justify keeping it 'awake'.

my phone wont stay on and when it does come back on it shuts right back off. the LED light on the front keeps flashing red. ive taken the battery out and everything and nothing seems to work. help please!

There might be some issue with the BlackBerry Device Software associated with the BlackBerry smartphone so Upgrade the BlackBerry smartphone with a newer version of BlackBerry Device Software and make sure that you have taken a backup before upgrading.

You can always try and reprovision your phone and resend the Host Routing Table (HRT) but if it is constantly dropping service it is probably a hardware issue and not something that can be permanently fixed. It could also be a radio issue but I would take it back and request a new one.

turn your phone off and turn it back on and clear your memory cache.
