Random BackLight Bug - JASJAR, XDA Exec, MDA Pro General

Hi, first time posting! so hello everyone 8)
I got xda exec, i had this problem with the first rom and the latest one too. For some random reason when my phone comes out of standby sometimes my backlight is off. i struggle to see my screen and when i check my backlight settings (brightness level) "on battery" its set to off on the slider. When i set it higher my backlight works. Also my backlight button does not respond when this happens. It just randomly happens but im starting to notice it more and more. Any ideas peeps

Try:
1- pressing the button beside the volume slider.
or
2 - pressing and holding the power button.
Hope that helps

thanks but i tried both, doesnt work. the only way it comes back is by going to backlight settings. Is there a file that could be corrupt that stores the information about the backlight settings?

Is the box "turn on backlight when a buttonis pressed or the screen is tapped"?
Other than that i've not got a clue. Someone who knows a bit more? any ideas?
JAmes

yeah thats ticked. the only way i get the back light to work when this happens is pushing the slider up, the one in the battery settings

seems real odd.
If noone else has a suggestion a hard reset might help, dont know if you've tried that yet. If you do this dont forget to back up everything.

Hi,
I think it really is the POWER button: if I press and hold it for a few seconds, the slider goes to zero and the light goes off. Press and hold again restores the old situation.

My wife's Magician did this sometimes too.
Turned out that in her case it was because when you hold down the power button to turn the phone off (for a second or two) it doesn't actually turn the phone off, just the backlight. (Of course it all goes dark, so it looks like the phone is off if you don't check too closely.)
Then when you press the power button to turn it on again (after it's timed out and turned itself off), there's obviously still no backlight...
May not be your problem, but give it a check...

In nearly three months, I've had this happen perhaps four times. My device has the "on-battery" backlight set at one notch, to save the most power, and I guess something must just move it that one notch down to off.
So far there's been no uniform circumstance, other than it's guaranteed to happen at night under low street or room lighting so that I can't see the screen to get to and re-adjust the setting.
A hard reset doesn't help. I've reset numerous times with different ROM versions and had the problem reappear - but very infrequently as I said.

just wierd and a tad annoying lol, i tried all of the above ideas anyway, i thought it might be bad programming thanks peeps for your input

I've had this a few times. I've had to hold the power button in for a few seconds to get the light back.

i had the same problem, just comed up a week or so. not changed any settings either.. wierd bug

screen brightness goes to zero

Anyone else find that some software can cause the screen brightness to slide down to zero, so you have to go through settings and slide it back up via several irritating clicks. Not sure what software is doing it

yup
use to happen onxda1, happens only sometimes on xda 2

Yup it happens sometimes. I think I figured out when that happens.
It happens when you press the Power Button not all the way e.g. when you apply only minor pressure to the button. Normally this happens accidentally when you want to Power Off the XDA. SO instead switching off the the XDA, if you do that (i.e. press power button not all the way), the brightness will go all down to zero.
I think the "half press" of the power button to dim the display is an intended feature not a bug. Was the same on my iPAQ before moving to the XDA II.
I have had ythe odd occassion (twice only) where after a soft reset the screen brightness was set to zero. You have to go to the screen settings and slide up to your desired setting again.

Backlight keeps turning off

I keep finding the backlight on my XDA II keeps turning itself off, I have to go to the backlight menu and I find the "on battery power" backlight setting is set to minimum. It does this randomly with a fully charged battery. Might have to buy a torch if it keeps this up!!! Any ideas?
I thought I had the same problem, but it turned out to be my own fault.
My XDA II would be off and I'd press the [Power] button, to turn it on ... no backlight. I discovered, quite by accident, that if you press and hold the power button, it in fact turns off the backlight.
So ... when turning it on, make sure you just press the [Power] button and DON'T linger.
HTH
ardarby is quite right. It's a great option once you know about it to save battery... I use it all the time now, when I'm outdoors if you push and hold in the power button it turns off the back light. If you want it back on just do the same.. Push and hold the power button...
Nice one!
Cheers! I was on the verge of a 20 minute wait to speak to Orange support, thinking I had a hardware fault!
I had the same thing when I had my XDAI. Strangely it seemed to happen every time my gf had been using it, and in the end I worked out she had assumed to turn it "off" it was the same as Nokia's where you have to hold the power button down.
Saved me a similar call to o2!

thanks for the hint, I had the same problem with my qtek 1010, that I got mad at my kids (poor kids) every time they used it I get it back with no back light. It is a bit different with the 1010, you press for power, and then you can toggle between back light on/off by a second long press on the power button.
Well, now I see no need to buy a new one :lol:
this forum is superb! My problem with backlight off solved again
Thanks all

Problem with Power off

I have problem with power button. when push pwr button dont,t off pda, but when hold pwr then lights off.
Power is never shut off in PDAs, thats the way PDAs have been designed.
I have the same problem, he is not talking about a full power down. If you hit the power button quickly the phone does nothing. However if you hold the power button down for about 2-3 seconds the lcd light turns off as it should.
Because of this I have to wait 1 minute for the unit to suspend before putting it back in the holster.
Does anybody have any idea as to why this might be happening. Im not new at this so hard reset, soft reset.. new rom... new radio...turning up side down while chanting. It does not change......
It will do it right one or twice in a week.
Maybe somebody that understands the signal that the unit receives upon pressing the power button might be able to shed some light on this.... Again the button does seem to operate just not suspend when pressed normally (1 second or less)
I have done some more research and this seems to be a common problem for some with BAs but nobody has found out why. There must be some kind of common hardware fault.. Does the power button send only one signal or is it a multi signal device.

Do you have a problem with turning on? First, we need to know whether it is hardware issue or not...
What you can do in the mean time with the turning off problem is by installing a poweroff app like shutdownme, psshutxp, etc etc...
Absolutely no problem with turning on from standby... Right now i just lock the phone before placing it back in the holster.
To make it clearer if you HOLD the power button down the backlight will turn off only. It will still show the display image and keys will still function (it dims)
Well, I had the same issue with the latest WM5 ROM. I thought I was too stupid to press the button, then I thought the button was broke, then I thought, I'll have to live with it.
Now that I have flashed to WM6, no problems at all! Never even came to my mind that this problem once existed. So I guess that some ROMs just have this particular bug?
Stefan
I have tried all the roms as well as 2003 and have the same issue in all of them. And im not alone.
Power off Problem
I'm in same condition.
Had the same problem when using WM2003 second Ed.
Now I've installed WM6 but nothing changed:
I cannot power-off/suspend but can turn off backlight if press and hold power button.
When in standby the button works fine to turn on the device.
Also, sometimes volume turns up continously with "noisy" beep ...
Anybody solved this problems?
Thanks,

Power button has two modes:
1. Click mode: Click it once for a short duration. This turns off backlight and can be resumed by pressing it again or by pressing OK button
2. Press and Hold mode: Press and hold for few seconds and release. This mode will dim the backlight and no other button will bring it back. This is some kind of deep sleep in battery mode. To resume the original setting, press and hold Power button again for few more seconds.
(p.s.: I am not sure if this behavior is true for all the BA models)
April 1,
I know these modes...
It seems that "mode 1" doesn't work at all...
I would activate "Button Lock" (settings-->button--> Lock(tab)--> "lock all buttons except power button") to turn-off backlight and "lock all buttons except power button" but I cannnot...
You solved this problem?
I have had this issue of not being able to power off. One way I always got out of it was by clearing the registry hive. Unfortunately this brings the PDA back to the basic ROM. At this point the power button worked without any issues. Upon reloading the software the problem may come back. I believe the issue is related to some programs. I can't recall which program it was that seemed to cause the issue. One other thing I think that also worked was just entering the registry and getting back out and doing a hard reset.
I had the same problem with my 6600. the message button also didn't work. Believe it or not, to fix it. I banged the lower half (4-way area) on my desk a few times. Not hard enough to break the screen. But prolly hard enough to free what was prolly a sticky key. And now everything is working.
i am too
the same ...
when i press the power quickly , nothing happen
when i press the power for 2 sec. the backlight turns off
i tried every thing .... including formatting my BA
any one solve it ???
I have this same problem, my power button does`t work. i tried installing different roms but without any chance to fix it. maybe its an mechanic issue. i will change pwr button, i hope this work.
Look at one of my previous posts. I fixed it, twice, and other users have used the same metod to fix it. I think the problem is "hung bit" hardware related because you can also send it in for service, and they will change a chip, but i never had to.

Crazy volume problem

Basically, it is as if the top volume button is held down, and the volume is continuously going up on my HD, even when I try to turn it down, it shoots back up again, and is stuck on the volume screen. Sometimes, if I turn it down to silent, it will stay silent for a few seconds, then the volume goes up again and keeps going up.
Really annoying as it means the phone is basically unusable as I'm pretty much always trapped in the volume screen!
Any ideas?
I would suppose that a button is stuck!
Take of the back cover and take a good look at the buttons to see if anything could be wrong!

That's what I thought, but it looks fine to me
I had the same problem as you but I then realize that when I was putting down the volume while in a conversation was my face pressing the screen and increasing again the volume...could it be your same problem?

Nope, because it happens if I don't touch the phone and just leave it on the table
Have you tried a hard reset?
Do a backup first.
Turn off the phone. If you can't pull the battery out.
Hold the volume up + down at the same time then press the power on button for about 1 second. Let go of the power button while keeping the volume up and down still pressed down.
You should see a blue / green / red screen then just follow the instructions on screen.
If this doesn't solve your problem then most likely something is keeping your volume up button depressed internally. Take it back for repair...
The volume slider malfunctioning is a big one on HTC devices known issues. I've had the same problem with my elf....and I've seen plenty that do too. Your best bet would be to take it to an authorized service rep. Sucks I know
Try to remove the cover and use it... the pressing mechanism is on the cover...

Tried that, still the same problem.
I'm going to try a hard reset today, if I still get the problem, going to ask Orange to replace it. I wonder if they'll let me pick another phone, I'm getting a bit fed up with the HD!
I have the same problem, it occurs randomly and I discovered that if I quickly press the power button to stand by the phone and press it again to exit from stand by, the volume bug disappears and phone starts working well again. I thought it was a software bug but I still have it on 1.19. It rarely happens now on 1.13 was more frequent.

912c Power Button acting funny

Hi,
I am using iPad 912c. I love this machine but the little silver power button is acting funny sometimes. Normally, when I press the button the screen should be turned off immediately. But sometimes the screen still on for 4-5s after pressing the button. First I thought I didn't press the button properly. But if I press the button several times the machine can remember how many times I pressed and switch the screen on and off (sometimes ask me if I want to turn off) like having a ghost inside. Looks like it has a buffer for the power button. I don't think it is the software problem. Because I tried to soft reset the machine. The machine still remember how many times I pressed the button before reseting and turn on and off the screen several times after the machine back on. It happens twice a week. Is it a hardware or software problem? If it is hardware problem the iPad should not know I pressed the button several times. This is not a popular machine but I am sure it is one of the best. Please help. Thanks.
Anyone has the same problem? Please help
Hi!
