Searched and searched but couldn't find an answer.
As the title says.... I can still see the display is on and its responding to my inputs but no backlight at all.
Have tried adjusting all backlight options disabling and enabling them to no avail.
always start to happen at 50% power then every 5 or so secs it turns off so i need to press the power button twice to turn it on again but have it turn itself off if i left it to idle for more than 5 secs.
Settings currently for on battery at dim backlight 30secs, power off 1min. on AC dim at 1min, power off at 10mins
Comforting thing is when playing videos with coreplayer, backlight remains on.
Anybody any ideas?
started when i flashed back to official 1.66 after mtty and now am on merlion 2.4 also after mtty. could it be that i always flash at the 50% to 60% power mark??
Currently draining my batt to see if it is the batt sensor's problem....

backlight
have u checked the backlight settings, theres a separate bar for the backlight when plugged in.. that might be right down..?
there could be a registry thing to stop it too...
Start | Settings | [System Tab] | Backlight
Within here, you have 3 tabs at the bottom of the screen.
Brightness, Battery Power, External Power. On the latter two options you should have the option to change whether or not the backlight stays on in those circumstances. For example, you can switch the backlight to go off after 10 seconds on external power.
Check this If it is still causing the issue when you have unchecked both of those boxes, well, you know where we are
tried all the backlight settings ..... brightness, battery power, external power.. ...but nothing worked ...the backlight used to switch on as soon as charging wire was removed or was put in camera mode even while charging.....finally had to reinstall the rom....now its fine....
While on battery -
backlight set to turn off in 30 seconds, and power management set to turn phone off in 1 minute. at 30 seconds, the backlight gets dim, but doesnt actually turn off (weird). At 1 minute it turns the phone off as it should.
So the backlight isnt actually turning off when it should.
next....
While plugged in -
Backlight set to 1 minute turnoff, power set to turn phone off in 2 minutes while on external power. At one minute, the backlight goes dim (not off again), and the phone never actually turns off, just stays on with a dim backlight screen.
Any ideas as to why the backlight wont turn all the way off? This just started when i flashed the GPS ROM.
Hi all
I've installed quite a lot of ROMs and found lots of them have the option to dim the light and then turn the screen off pretty quickly (like 10 sec). I know that going to Power / Advanced I can change those times, but apparently only the dim is changing.
For instance... by default the screen in my current ROM (made by Topix) goes off after 10 sec. So, after 5 sec the light dims and then after 10 sec all goes black. Fine... then I change the "Turn off backlight if device is not used for:" to 30 sec, and what happens is the light doesn't dim, but after 10 sec the screen goes off.
Does anyone how to change this? Is VERY annoying :-(
Thanks
I've done the usual search and can't find anyone reporting this . . .
If I turn mt AT&T Pure off with the power button (not complete power down, just normal on/off) I notice a faint glow from the screen like it's still trying to show the backlight.
If I power up and then power down a second time, there is no glow.
This phone is running stock AT&T ROM, and it happens on battery power - so I'm concerned that it's draining the battery unnecessarily.
Battery settings -- "Auto adjust backlight" NOT checked
power save sliders around 30%.
Advanced tab -- "On battery power" - both boxes checked, 30 sec backlight off, 3 minutes turn off. "On external power" - neither box is checked
Any ideas?
Thanks
Try installing this cab, changes registry to auto lock with power button.
If it doesn't work, you may consider a lock screen such as smart lock.
Thanks for the post, but I don't understand what it does -- could you explain how the phone should behave after installing the CAB?
Thanks
Using this reg edit makes the device go into standby once you press the power button, no backlight staying on etc.

MY HD2 backlight is in all ways on only in battry power
when i restart my hd 2 the back light is in always on when i press the power button it will go off and within two scened it will come back . i checked the back light options it is in

and i noticed that when the device is in this misbehaver if un tick automatically adjust back light and then if i increase the Brittnes of device on battery power it wont increase even the dives is in actually in battery power if in this time i can increase the britness of the on external power
Never heard of this before, you could try a Factory reset and see if that sorts it, ot if you have a non stock rom, flash a different one
