Slightly annoying, but it appears that the backlight on my phone won't turn off - unless I lock the phone.

The backlight dims down after the preset time, but no matter how I configure the settings in Home Screen or Power Management it just won't turn off completely. The only way to get the backlight to go off is to lock the phone and then the screen finally goes black.

Anyone got any ideas before I reset the phone and have to set it up again and re-install all my apps?

I have the same exact problem. But in my case, even if I lock the phone, backlight STILL STAYS ON.
I have a TomTom Mobile 5.21 installed. May this cause that problem?

Tried uninstalling TomTom but no luck.
Any suggestion before I try an hard reset too?

I confirm that the problem appears after you run tomtom 5.21 for the first time. Then you have to hard reset to restore backlight functionality.
Maybe I have to upgade to TT6.

Well. I'm not running TomTom - yet I'm still having the same problem; the backlight dims down, but never completely turns off, unless I lock the phone.

I did a hard reset last night and then reinstalled my apps. The backlight was working perfectly until I installed my last couple of apps. So, at this point I think it might be down to The Core Pocket Media Player as that was the last app I installed and the backlight is playing up again? ;)

Is anyone else having problems?

I've read at another forum that it was Core Player/TCMCP that is causing this problem.

Thanks for the info - in that case it looks like my suspicions were correct.

Then you should have no problem.
Or maybe you are not looking very well. \HKCU\Control Panel\Power\ value display.


Use mobileregistryeditor

I am now confused. Do you mean edit the default string, or create a new string key called value. A screen shot would be nice.

Also when I try and experiment myself using MobileRegistryEditor I keep getting Access Denied, am I missing another trick

Create one called 'Display'.

You will need to Application Unlock your device.

Great tip. I had the same problem after installing tomtom 5.2 on my SPV E650 and was searching for a solution.

I have some feedback too: Using MobileRegistryEditor.exe (version 1.1) I was able to make the setting change without needing any application unlock.
Maybe that's because my Dutch SPV E650 doesn't have an application lock, or maybe that's just because of how MobileRegistryEditor.exe works. Anyway, solution tested and working great.
