Turn off screen completly - Windows Mobile Development and Hacking General

I would like to develop a program (in VB.NET) that turns off the sceen completly, and the only way to turn it back would be to do a soft reset.
Any ideas??

8125 stuck with no disply

Today I had an alarm set, when the alarm went off I tapped hit the power button on the top of my phone to turn the screen off (and hopefully the alarm... but only the screen went off). The alarm continued to go, but no matter what I did, I couldn't get the screen to come back on.
I can fully interact with the phone (as if the screen was on). For example, pressing talk twice redailed my last call. Pressing power prompted to shut the phone off (could hear the "blurp"), etc.
So, after shutting the phone off (or resetting with pinhole reset), the display works fine while it is displaying the "Cingular - Raising the Bar" nonsense. As soon as that screen is done (where it would have normally showed the today screen), the screen just goes off...
Any ideas?

nevermind, when I put it under a bright light I realized the screen was on, the backlight was just off... somehow I must have hit some shortcut to turn the backlight off.

Don't sound too relieved...
Say hello to the Backlight bug.
You're backlight will keep setting itself to the lowest setting after every soft-reset, when you let it go into stand-by itself.
I'm still sufferering from it. It started when i first installed PocketZenphone.
So just want to give u a warning. Everytime you reset your phone, remember not to let it go into standby itself. Either tap the power button and turn the screen off, then turn it on agan. Otherwise, the Backlight will go to low again.

Backlight dims, power button doesn't work properly...

I have had the Touch 3G for nearly a year now and for the last 3 months I have had this recurring problem which is fixed with a hard reset but will recur again after about 6 weeks. The symptoms are:
1. When turning on, the backlight dims just before the HTC flash screen and startup sound (when it says "Smart Mobility")
2. Touching the screen doesn't bring the backlight back on.
3. Pressing the power button doesn't turn the screen off from this dimmed state, but after pressing touching the screen will turn the backlight back on.
4. Pressing the power button again will now turn off the screen, but pressing it again won't turn the screen back on! If I call it from another phone, the vibrator goes on but it doesn't ring, the screen stays off and you can't answer the call. If you hang up on the other phone it keeps vibrating and you need to do a soft reset to stop it.
If I do a hard reset the symptoms are gone and reinstalling the exact same software doesn't cause the problems immediately but withing a month or so it happens again. All I did just prior to these problems was use TomTom a bit more than usual, but otherwise nothing different. I have used TaskManager to see if there is anything weird running in the background but it all looks fine. I have had a cursory look through the registry but also can't find anything?
Any advice would be appreciated.

Sounds like it's going all haywire. If you've had it less than a year, I'd send it in real quick. Sounds more like a hardware problem.
I don't think it is hardware as a hard reset fixes it...it just recurs down the track. I have done a hardrest and reinstalled all my apps and it is working great again but I was wondering if I should be checking somewhere in the registry for an aberrant setting. I am u using a backup image program so at least when it happen again I an restore my system more simply.
But then again, all the symptoms you mentioned point to a hardware defect. You could try to find a tweak, but like all electronic devices, it's the luck of the draw. Try emailing HTC and see what they say.

Help! White screen and no reset

Hello,
I have a Wizard g4 with hard SPL and this weekend it decided to go crazy. Here is the problem:
- When I turn it on, the screen goes white, blue and orange LEDs are lit and the device vibrates non stop. The camera white led is also lit.
- The only way to turn it off again is removing the battery. reset is useless.
- I try to put it on bootloader mode using the camera+reset and nothing happens
- Trying to turn it on with camera pressed also doesn't work
- Trying to turn it on with voice+network pressed doesn't work either
- When I connect it to charger or USB, it automatically does de same (white screen, etc) described above
I've been using Hornet win 6.1 ROM for some time and was very happy with it.
Is there any hope or am I effed?
Seriously? Nothing?

You don't say anything about doing a hardreset. Did you try it?

Help Please! Nokia 6.1 Plus Screen Turns On But Remains Dark

Hello guys, my Nokia 6.1 Plus has developed a weird problem. When I turn on the phone the screen lights up as normal, displaying the androidone logo followed by the NOKIA logo before proceeding to the homescreen where it operates as normal. However, when I press the power button to turn the display off or when the display times out and goes off it doesn't wake up. It remains dark when I double tap on the screen or when I press the power button. The screen turns on but remains dark as I can feel it vibrate and respond to touch when I touch anywhere on the screen. I basically have to restart the phone to get it working again. The phone is basically unusable as I can't have the screen stay on all the time for me to use it.
What might be causing the problem and what can I do to remedy it?
Try to backup your important data and perform a factory reset.
May b it's hardware problem
