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.
I've had a problem with my E900 since I got it with regards to the screen. I was hoping Mango might fix it but it doesn't seem to have.
Sometimes if I press the power button the screen backlight comes on (i.e. screen goes from off state to powered) but there is nothing on the screen. No amount of button pressing will cause the screen to show anything.
If this happens I have to turn the device off again (backlight then goes off) and try again. Sometimes it can take 2-3 times before it turns on successfully with the lock screen.
I also have this if an incoming call attempts to wake the phone and also alarms too.
Does anyone else have this issue?
I confirm this one popping sometimes. Not that often that it becomes annoying, but nevertheless.
Did you find a solution to this problem? I am experiencing it too and it is very annoying!
I've recently inherited one as well (E900 that is).
The one I have has been dropped, the backlight powers, but no drawing on the screen.
I've disassembled and re plugged everything (bugger stripping down!) but still no luck. I've done a VolUp+Down+Cam+power hard reset, and when I plug into PC Zune says setup needs completing (so it has reformatted) but still no luck.
I cant see anything fried, and no damaged ribbons as far as I can see, any ideas?
I sold the phone a while ago, and never solved the problem. I think it's a firmware issue.

hi.
What do you mean "somethimes if I press power button"?
Is it pressed with purpose to lock the phone, press it to turn off phone (background slider shows to power off - on Mango and beyond version) or press it accidentally?
Cheers.
So, I did a phone reset. Unfortunately the issue is still present!
Sometimes when I press the power button to unlock the phone the screen is lit, but stays blank i.e. no lockscreen wallpaper, no nothing. The same happens sometimes when I get a phone call - the phone rings and vibrates, the screen is lit but stays blank.
When this happens I have to press the power button to put the phone into sleep mode and press it again to wake it up.
What I found is, when the issue occurs the screen is actually responsive. For example I can slid up and unlock the phone then I hear the unlock "pop" sound. It's just that nothing is drawn on it!
I was wondering if anyone else experienced the same behavior and found a resolution. Also I am not sure if this is a software or a hardware problem. If I could confirm it was a hardware problem I would call LG and have the phone repaired or replaced.
i have exactly the same issue as you, it gets really annoying.
i heard from someone online that the only way to resolve it is to replace the motherboard

I am pretty certain this is a hardware issue. I am calling LG tomorrow and hopefully they'll take the phone for repair/replacement.
I sent my phone for repair. Today I got it back, and guess what?!
The issue is still present! It seems, they "couldn't reproduce" or something.
What should I do now?
EDIT: If anyone is interested, here is a video I just captured which clearly demonstrates the problem. http://youtu.be/38kF9RYs_bU
I'm sending the phone back for repair tomorrow with this video attached.
Hey, might not be an issue at all, but in the video, I saw that the two times you were able to get it to go blank you had your finger on or near the proximity sensor. I wonder if there is something that could be the trigger.
Just wondering if you can duplicated it or cause it only when you have the proximity sensor blocked, or if it truely is random.
You are right, it might has something to do with the proximity/light sensor.
On the other hand, this issue occurs even on incoming calls when the phone is placed on a table, screen up and nothing around the sensor.
Today, I visited my local carrier shop and left the phone for repair again. They told me, since this is a second claim they'll run it through the process faster, so I expect to get it back next week.
Will post an update.
UPDATE: My phone was replaced. Yesterday I got a brand new unit, yeah! It was stock wp 7.0. I plugged in my sim and used the phone the whole day, no sign of blank screen issues. Last nigh I installed all the updates (total 5 I think) up to OS 7.10.8107.79, FW 1.0.16.10. Guess what?! Same issue!
I am crushed
When I go to unlock the phone with fingerprint i need to physically press down, I thought it may be ROM issue but I went back to stock and still a problem, has anyone else had this happen, it works so it's not dead.
I think the press down to turn on screen method is standard. I've always had to do press the fingerprint/home button to turn on the screen, and the fingerprint recognition/unlock happens simultaneously.

this is standard as long as the screen is tuned off. If screen is on the fingerprint is read without the button being depressed
Yes, the FPS only works when the screen is on. Normal. Cuts down on battery drain by not keeping the FPS live all the time.
I've got a strange problem with my Sprint Galaxy Note 3.
What's happening is that randomly when I hit the power to turn the screen back on, it will do nothing then the screen will stay blank. The phone clearly still works because if I'm on a call or listening to music it will still keep playing and the volume and other buttons continue to work.
When that happens I hold down the power to turn the phone off and then on and it boots up normally.
Rarely what will happen is the same behavior except the screen will go strangely green after I hit the power button, making the phone unusable until an off/on.
This happens sometimes multiple times a day, sometimes days without happening.
Phone is rooted, running OC5 on Android 5.0. Problem has been happening for months. Haven't made any system upgrades or installed any major apps so that isn't it. I'm thinking it is some kind of loose pin/wire but don't want to crack the phone open without a plan.
Any help appreciated!

About every 1 in 3 times I try to turn the phone on, the screen remains black, but I know it has "woken up", because it vibrates under my finger to indicate it has unlocked. Additionally, swiping around while the screen is black results in opening main screen apps. I have tried face unlock, fingerprint and voice unlock and these methods all have the same kind if success rate. I've found the only way of turning the screen on is, after unlocking it, is to hold the power button to bring up the force shutdown menu. This issue has gotten progressively worse over a number of weeks. I run an app launcher, may be contributing? The phone is about a year old. Help!
