    A couple of months ago, the maximum brightness on my Treo 650 screen suddenly became much dimmer. I compare it to anyone else's 650 screen and the difference is obvious. (Yes I've made sure I'm at maximum brightness setting.) The problem is exactly the same with a fully charged battery or a nearly discharged battery, and with or without the power cord plugged in. I even did a hard reset to see if I had messed up some factory setting - no change in the problem. So I'm convinced it's a hardware problem, not software. Has anyone else experienced this and/or know of a solution? There are a couple of threads about people whose screens didn't work at all, but that's not the case here, so I was looking for some advice before doing the "open heart surgery" to my 650, which still works fine otherwise.

    Since nobody has offered any ideas, I thought I might make a suggestion (but you probably checked this already).

    If you have another kind of utility for example 'Butler' that can dimmer the screen based in the time of day. So when it's night out, you would want to dim the screen to save on battery life. This type of control might override the max setting when you use the keyboard to adjust the screen.

    So please check for any utility that you might have that has this type of option in it, and maybe it's default setting is doing this.

    Sorry that I can't offer anything else, but it's the best I can do.

    Third party software like Brightcam (not definite about the name) does affect your screen display brightness and Profiles also.

    Hi bobodobo. Sorry to hear about you problem. Anyway, that's what I think you should do:

    1 - After a HR, test the screen light BEFORE you reinstall any previous backup session or any other software whatsoever;

    2 - If the above fails, I recommend that you install a different ROM. Note that this is a VERY SENSITIVE procedure, but I would use it as last resort, since if your problem is in fact hardware, you will have to replace your motherboard . I strongly suggest that you ask someone more experienced (if you are not) do do that.

    3 - Try to have your Treo examined by an specialist.


    I REALLY hope that you can solve this issue...

    Have you tried pressing the option key and right shift key at the same time. This is a feature for dimming the brightness of the screen quickly and maybe it is stuck at the dim level

    Thanks for the tips folks. Here's what I've found DIDN'T fix the brightness issue

    • Hard reset (no 3rd party software installed)
    • Screen dim utilities
    • Option-right shift (dims the screen even further, hitting Opt-right shift again brings it back to the usual (dim) state)


    I am using a custom ROM, but I'm 99% sure the problem started a long time after my last custom ROM upload. Still, it might be worth going back to the factory ROM just as a reality check.

    On the other hand, the 650 is a dated device; I'll probably upgrade in the near future to a 700p (Verizon) or 755p (Sprint; I'm past the contract period with Verizon, and EVDO for $15/mo on Sprint is mighty tempting.) So it might not be worth monkeying with the guts of the device.

    Anyway, keep the suggestions coming!
