    BB Gurus: Backlight Issues!!

    Advertisement



    Hi All,

    I know, I know...there are many threads regarding this issue. I am now just exhausted. My backlight just does not want to stay off! I have the 4.2 OS. I thought maybe a software problem. But I don't think it is. I went back and installed the 4.1 OS from Rogers. Still had the issue. Tried and re-installed the new 4.2. Still had the same issue!

    Whenever I go to lock the phone, the backlight shuts off but then instantly turns back on with out me moving the phone or pressing any buttons. same thing happens when I go to lock the phone..Backlight shuts then instantly turns on again! Tried pressing the dim function button on the top of the phone. Push once=brighter, Push twice=backlight off.....then turns back on!!

    Please, please help!! (My wifes 8700r)

    What are your backlight settings in Options>Screen and Keyboard? Do you have any apps installed that have some control over the backlight, like BBLight?

    When you have new messages (email or text) and phone calls your phone will light up and than you'll have the red light blinking for a bit...maybe that could be the problem

    When you lock the phone, the backlight will stay on, and it will follow your 20 second time out. My pearl does it, my 7105t did it. What's the problem?

    Have you tried a battery pull?

    Could be a defective key that is making the backlight come on (or some other defect) as well.

    The problem is when the backlight does time out, it just truns on again without any buttons being pressed.

    Mark, how long have you had your BB? If you're still under the warrenty period you have the option of taking it to a storefronot for your vendor and have them make it right.

    no longer under warranty....

    It's just annoying to always have to put it in the holster to save battery life....
