Touch Screen not working - Bold 9790

Hi!

 

My touch screen stops working suddenly. To restart I have to remove the battery and place it back. I get following message in the log.

 

Name: System
GUID: 97c9f5f641d25e5f
Time: May 31, 2012 21:34:57
JVM:INFOp=28adba7f,a='7.0.0.473',o='9.16.0.33',h=26001507

Pls suggest me how to resolve this problem.

 

Regards,

Re: Touch Screen not working - Bold 9790

Hi and Welcome to the Community!!

 

There's pretty much no diagnosing those -- they are the equivalent of the random errors in Windows for which tracing the root cause is fruitless. Basically, these are the last out in the programming code -- some event occurred for which there is no handler in the code. The fix is a code update that handles the event...but, again, knowing what the event is is pretty much impossible. So, there are a few things to try:

 


Sometimes, the code simply becomes corrupt and needs to be refreshed -- just like a reboot:

  • Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.

 



If it won't boot up cleanly, then you may need to try Safe Mode:

    • KB17877 How to start a BlackBerry smartphone in safe mode


There might be an updated code set from the carrier -- check them via this portal:

 


The toughest possible cause is a badly behaving app. To find it, there are a couple of options. One is to see if you can read the log file:

Go to the home screen. Hold down the "alt" key and type 'lglg'. (You will not see anything while you type).This will bring up the log file. Scroll down (probably many pages) untill you see a line that says 'uncaught execption'. Click on this line. The name of the app will be in the info. Alternative methods for bringing up the logs are in this KB:


  • KB05349How to enable, access, and extract the event logs on a BlackBerry smartphone

Since you've already done that and there appears to be nothing helpful, the other method is to remove apps one at a time, waiting a while in between (I usually recommend a week), until the problem ceases...thereby discovering the offending app. Still another method is to reload the BB OS cleanly, leaving some time between adding other apps onto the BB so as to be able to determine exactly which one is the cause.

  

Good luck and let us know!

OK...so that's what, 2, of the 5 or 6 different things up there? Are you expecting someone to interpret your log information for you? I'm confused...so please do check the rest of what is already posted.

Re: Touch Screen not working - Bold 9790

Sometimes applying pressure to the top part of the bezel just above the screen  nearer to the top left side than touching the screen helps significantly
