Backlight resetting to minimum when device switched on

For some reason my device has suddenly started switching to the minimum backlight setting whenever it's switched on. If I go to the backlight settings and then adjust the slider it will stay at the selected brightness until it switches off. When it switches back on again it's at minimum brightness and I can hardly see the screen!
This started happening after I installed and then removed PocketZenPhone.
I don't really want to hard-reset the device unless I absolutely have to - does anyone know what registry key sets the default switch-on brightness?
Thanks,

I dont have the solution but I have had the same problem intermittently. Can be really aggravating in the dark because it can be hard to get to the proper screen to increase the backlight. Hasnt happened in a while. Have not been able to figure out what triggers it. Have not installed PocketZenPHone. Curious if anyone has an explanation.

yah, i've noticed this to, sometimes i'll hit the power button to take it off standby and the backlight would be off. first couple of times it scared the hell out of me cuz i thought the screen had broke or burnt out.
also i noticed the version of spb pocket plus i'm using (3.04 build 4195) doesnt adjust the backlight brightness.

Now that you mention it. the SPB Pocket plus backlight does not work for me either. Strange...

Well I think I've managed to "fix" this by setting the following;
Backlight Settings:
On battery power, turn off backlight if device is not used for [5 min]
Turn on backlight when a button is pressed or the screen is tapped
Power Settings
On battery power: Turn off device if not used for [3 minutes]
I think the key thing here is to have the device auto-switch-off BEFORE the backlight timer kicks in. Since setting the above three settings I have not had the same problem again.

Ill give it a try as well.

Hmm...maybe someone can help me. One day, my backlight timer settings when the PDA's not plugged in reset to 10 seconds (in the registry it has it as 7 seconds). I'll go in and change it to 2 minutes (the original setting I had it at), but the minute I turn it off, it resets back again to the 10 seconds setting. I even tried going into the registry and changing it, and it resets it back to 10 seconds. I suspect it may have something to do with an entry in the "scheduled tasks" but it looks like a complete mess. Is there some kind of scheduled tasks cleanup utility?
Thanks,

hello i have the same problem using phothet with WM6
Thanks
Nicolas

I had the same problem often about 15 months ago - it happened often each day.
I posted herw but had no joy with a solution - but then found one on Modoco (i was looking about March/April 2006).
Even with that - it has still done if perhaps five or six times since - and basically makes the phone unusuable if it happens somewhere or time with poor light.

My KJam backlight keeps changing by itself to dark
Suddenly my KJam backlight always turns to low without me doing so, then I have to change it to high, barely can see what I’m doing as it is almost black. This is kept happening especially after I installed Pocketweather. I reinstalled the Rom, it worked fine then suddenly it is back again when I switch the screen off, or automatically it is switched off, the backlight slider I find it at the lowest end.
Why thus is happening, it’s driving me crazy, please help me

HELP!! Backlight goes to power saving mode by itself

Anyone know how to get the backlight back to the original setting? I tried to go into Settings to Battery Icon and clicked on Backlight and adjusted it there but everytime the phone goes into sleep mode, the backlight always reverts to power saver mode and I cant see a damn thing on my screen. It is very frustrating...anyone know how to correct this problem? Am I doing something wrong???? TIA....M3

I have the same problem, but in my Wisard the problem happens when a soft reset is executed ... I was searching about it on the internet and I found that maybe the problem is an incopatibility between the fone and the SPB Pocket Plus backlight functionality ... I will try to uninstall the SPB to see what happens ...

Here's my backlight bug theory...
On the Wizard there are problems with any programs that try to change the backlight settings and often the result is they end up turning it off.
PocketZenPhone, PhoneAlarm and SPB Pocket Plus all have features to control the backlight (do you have the backlight plugin installed on your today screen?) that load at boot, or on the Today screen, and these seem to cause problems.
I use PhoneAlarm and have problems on occasion. Believe it or not I found the solution was to tell PA to set the backlight at 40% which it can't be set to on the Wizard (25% increments only) and it stops shutting it off. If I have it set for 50% (which *is* valid on the Wizard) it shuts it off.
Anyway this is my theory on the mysterious backlight bug, if anybody else has any other ideas, I'd love to hear them.

If you go to the backlight applet and check the Turn on backlight when a button is pressed or the screen is tapped on both the Battery Power and External Power tabs you should be all set. Had the same issue after the last iMate ROM update and this is what fixed it.
Hope it works for you. Good luck.

Unintentional turn-on in the Jamin?

I've tried to do a search on this problem, but nothing came up. Maybe I'm searching the wrong keyword. If someone know anything about this, please advise. I got the Jamin recently, I pretty much went right into installing the 2nd ROM (vs the recent 3rd ROM). So I have nothing to compare to. For whatever reason, my Jamin keeps turning on by itself every few minutes. Not only that, it won't automatically turn off using the Power setting. Whenever it's time to turn off (ie, after 1min), the thing automatically turns on again (with the backlight on). I'm not sure if this is a ROM problem, a hardware problem, or software imcompatibility. Please help.

Hey
I've also had this happen on my Prophet - it seemed to fix itself after a while, but I also had the problem:
press power button to turn off
press power button to turn on, and backlight was off
couldn't get the backlight on again except going through the backlight settings!
I did fix this using...

Run this app on your prophet, and your backlight is back to normal.
I've found this problem in a number of threads - I'm updating them as I find the solution!

Backlight always off on resume

Hi,
weird thing here: Always when I awake the device after suspend, the backlight is off. I have PZP installed, but it's configured to do nothing to backlight or power, settings in backlight/power are to never switch off backlight, but suspend after 2 minutes.
Any ideas where else I could check?

after mr.clean update, my backlight auto set itself to turn off after 10sec no matter what i do
I tried to set the back light to never turn off, but it still will not work
all i have running on background is spb pocket plus
CAN ANY HELP?????

hm, also mr. clean here.. coincidence?

My out of the box MDA Vario did this too. I finally figured out that it only did it if I changed the brightness level from the default to max. If I left it at the default, it worked fine on resume...

before the mr. clean rom I had a standard vodafone one, and didn't have the problem. What is default level (steps from topmost) for testing?

ok, i THINK i solved it now
it is caused by a software called vito audio note
http://www.pocketgear.com/software_detail.asp?id=21235&associateid=17
which will uses its power saving mode to turn off Wizard

I had the same problem. Rebooting the device didn't fix it. But when I actually SOFT-resetted the device, it came all back to normal.

Backlight off on resume, not hardware
Hello everyone,
I've got a very frustrating problem. Here's the summary:
My backlight doesn't come on when I resume from standby. However, when I soft-boot the backlight behaves as normal. After boot, if I continue pressing keys to prevent the backlight from turning off, then it operates as normal. However, if the backlight times-out, or if I put it in standby, the backlight refuses to come back on.
Any suggestions?

I bit the bullet
Well, i finally decided I couldn't live with the dark screen anymore and Hard Reset my 8125. It fixed the problem, but now I have to reload everything.
Oh well, now will be a good time to upgrade my ROM I guess...

SPV M3100 phantom backlight?!

ok well during the day and everything its fine but now as I type this message and when I'm generally in landscape mode using the keyboard my hermes backlight has a life of its own it turns on and off randomly...
no its not power saving, I'm sim unlocked but I now run the 1.09 bootloader and latest HTC rom and I'm getting to wits end. sometimes it can be fine other times not.
some may think what is he on about but it is happening to me and I don't even think its a hardware fault either or at least I hope not as most of the time my backligt behaves! anhone got any bright ideas as to what could be causing the flicking?

I have had a problem where the keyboard, when slid out, does not light up. Is this what you mean?
If so, I went into the control panel, switched it off in the settings and then closed it all down. I then went back and enabled it, and did a soft reset when it had all calmed down. No problems since
HTH

I get a similar problem, when I have read a message and switch to landscape mode and start typing, the backlight turns off and as i continue to type it will switch itself back on.
its a pain in the arse and is one of the bugs im hoping to get rid of on a rom update.

The keyboard has a light sensor. It will only light up in dark conditions. Maybe yours is playing up, or the light conditions that your using your phone in may be the cause.
I turn my sensor off so the backlight is always on, Settings---->Buttons----->Backlight
S.K.

Its the screen backlight that goes off, not the keyboard lights.
