Hello eveybody,
i have a rather serious problem with my prophet.
most of the time when i take my phone out of the pocket to use it, when i try to switch it on to use it the display comes to live for about 1/2 a second and then goes black again. in that time i can see the usual screen i was expecting but it instantly goes back to black, sometimes in good lightning i can see its just the backlight that is of but the lcd displayes correct, but sometimes the screen stays black. after a few such on-off cycles the phone starts to work normal.
the big problem is that once or twice every day it totally hangs not reacting to the power button at all, just staying black no matter how often i press "on"
i have to softreset to get the device back to working order
the green power lcd keeps blinking but thats about it.
when i get a call in that time the other party gets a normal ring, but on my side the phone does nothing, not even showing a missed call or anyting after a reset. so i will never know if i missed some call and since i can not tell how long the phone was in that "frozen" state it can bee that for half a day i did not accept any call no matter how often i was called.
is that some know side effect of flashing cooked roms or could that be a real hardware problem that i should have fixed by the vendor? could it be some "dirty" contacts that i just have to cleen?
anybody had those problems or knows a solution?
thanks in advance
I had the Standby of Death SOD this is when the phone fails to come out of standby with a power button press. This issue only affects some people on some networks. I'm not sure if its a network problem or a software problem but as only a minority of people have it, I suspect its mainly a network problem there is a software solution.
The solution is to change the phone settings band option from auto 3G/2G to either 3G Only (WCDMA + UTMS 2100 in Europe) or 2G Only (GSM + AUTO) depending on your requirements.
Also read this thread http://forum.xda-developers.com/showthread.php?t=540943&highlight=standby&page=2where the resolution was to get a new SIM.
Obviously this only solves the problem when the crash is because of the sim and/or settings which impact the sim. To rule out a software cause its best to start with a hard reset.

If I check in "Settings-System-Power-Advanced-On battery power" to turn my JAM off if it is not used for some time (e.g. 3 minutes), it goes off and then I can not turn it on. I tried to push/hold power button, nothing helped but soft reset. If I turn my JAM off manually by pushing power button I can turn it back on manually too. But after 3 or 4 times it acts just like it was turned off automatically, i.e. iregardless if I push or hold power or any button, LED flashes green and the phone does not turn on. The worst part of it is after I push Power button trying to turn my JAM on and LED indicator starts flashing green (and JAM still remains off) if somebody tries to call me he hears the signal as if my phone is ringing (not busy signal or "The number you dial is not available right now" etc.)
Does anybody know what the problem can be? I've got this problem even after hard reset with no third-party applications installed.
non functioning of on/off switch
Check the connectors of your battery on the inside of the JAM. I had the same problem and I found out that one of the connectors did not really "touch" the battery.
I checked it. The contacts on the battery look like they were scratched by contacts on the phone, so I'd think the connectors are in good contact. I even tried to put a small piece of paper between the battery and phone bodyon the left side to make sure it is really pushed to another side, it did not help either
JAM does not turn on after being turned off
Did anyone ever find out the answer to this??! I have the same problem with mine except it's a bit random - mostly doesn't turn back on again after an auto power off for a long(ish) period of time - like at night.
sounds like a possible fault is occurring. Best thing is to do a full backup of your system and then do a hard reset your device and see if the same thing is still happening. If it is, try the positioning of battery as suggested in earlier posts and if still happening, then a handheld service is required
A while after I've installed official WM6 somtimes only the backlight turned on when I woke the device from standby. And sometimes the hardware buttons stops working to. When this happends the lights in the green and red call buttons are on, even when I set the telephone in standby. Sometimes when this happends the orange charging light also turns on, and I get a bright blue flash in the bluetooth light(much brighter than the actual bluetooth light).
I've tried to turn of the standby, now the device never get black screen(it seems that the black screen only happends when I wake the device from standby). But still the buttons locks up randomly during the day...
I've tried to soft reset, and removing the battery for a while when the screen turnes black, but this doesn't help. Bootscreen and everyting is black for a while.
Now I've downgraded to official WM5. The telephone was ok for a while, but now it shows symptomes of the same problem.
I'va also tried to remove the SD card before I flashed the telephone, but I still get the same error without the SD card.
Is this a hardware or software problem?
Anyone else have this problem?
Now I've tested to disassamble the phone and cleaned everything with CRC electro cleaner, and I've tried every tips regarding the white screen of death, but nothing helps...
I've also tried with many different unofficial ROM's found on this forum, still no change...
I have the same problem, had it with both WM6 and WM6.1 roms. Just now the device woke up on its own from standby (with a dim backlight) and I was unable to turn it on. Sliding out the keyboard just blacked it out, and I can't seem to bring it back to life.
None of the hardware buttons are working either, and the only way to get it back to life is to pop the battery.

After i hang up on a call (when the phone is in sleep mode and the screen is locked) the screen unlocks. this is quite contrary to what is mentioned in the phone manual chapter 1 page 45. this becomes an issue since i use a bluetooth headset and the phone remains in its sleeve/case and after every call, a whole bunch of applications will launch since the case is in contact with the screen. have i overlooked some settings or are there other owners who have faced this issue?
ideas and suggestions welcomed
did you check it out if any of the hardware buttons being pressed against the case hence wakening up the phone.?
i had it to only closed al my apps in taskm and it stoped flickering
My HD2 is also behaving in the same way even in controlled test conditions - the phone unlocks when a call comes in (I'm presented with slide to accept or reject call) The phone unlocks during the call, but fails to lock again on disconnect (either by pressing "end call" or hang up via bluetooth).
Can anyone verify this? Is it interacting with something I installed?
I believe I found a (complicated) workaround.
What I want: leave HD2 inside pocket, answer calls with bluetooth headset, hang up and phone will go back to lock.
Problem: After I hang up using bluetooth or press the big red "End Call" button or the other party hangs up, the phone stays unlocked! It stays powered on and all kinds of buttons gets clicked.
Practically all lock sw uses their own lock screen (which I don't want to install). CSDevCtrl does not trigger by phone. TouchLockPro uses its own transparent lock screen but can respond to phone events. Using the !SUSPEND for TAPI\Ended under settings does not seem to work when the screen dims about 50 secs into the call.
Solution: Use TouchLockPro together with LockAndOff. Get TAPI\Ended to run LockAndOff will turn phone off, whether by bluetooth, big red "End Call" button, or the other party hangs up.
BTW: I think there is some confusion on whether the phone locks when you
1. press the big red "End Call" button, or
2. the hard "End call" button
in the forums.
I noticed that HD2 have a light sensor next to the top ear speaker.
During a call, if the phone is put near the ear and cover the light sensor , the screen become non-active which is good.
If anyone can come up with a lock sceen using this light sensor , then the problem with random launch of program when phone inside pocket will be solved.
This lock screen should only activated right after an end of call, beacuse , sometime you may want to use the phone in a dark place.

It's the proximity sensor that turns the screen on and off during a call, not the light sensor. How else would it work in the dark? (which it does)

My proximity sensor does not work, when I am getting a call my screen turn off and when I am taking the phone out from my face it turn on only when I am out side at the sun!! the screen stay off when I am inside room. I tested it with flsh light and it is working also.
I have a T-Mobile US version of the HD2. I am having the same problem when using the bluetooth system in my car. After answering or making a call the phone stay unlocked. And then starts making random calls while I am driving!!!!
There has got to be an easy fix for this!!!
Buy pocketshield, problem solved.
i have this unlock problem with 1.48 rom and i solve it by pressing start button and lock. after that everything works fine unless i change theme in settings. then just repeat first step.
Solved
Same trouble with me until I use the following software. I tried it and it's almost perfect. unzip it and just copy to your HD2, run CallerLoc.exe and click Yes, you'll find:when you hang up, or he/she hang up a call, or a call is established, the screen will turn off.
Why say 'almost perfect', the software is in chinese, but the filename is in english. and it's a call location software but with the function we need.
To stop or before you delete the software, run Callerloc.exe and click Yes again.
Hope this will help you. Sorry I don't find a English version of this software. I esure and I'm using this software perfectlly with my Leo.

Same for me
Greetings.
I understand this is quite an old thread I'm digging up but I need a little help as well and I didn't want to start a new topic just for that.
I've this silly problem, appeared right out of the blue:
You all know the standard manila behavior, when the phone is idle, the screen first dims and after some more time, depending on your preferences, the screen locks. It also locks if you press the power off button. This all was happening to me till this morning.
I added an event in the calendar (the only change I made today) and after that, my phone dims and then goes in sleep mode after the designated period of time, but DOESN'T lock!!! It doesn't even lock when I press the power off button. I can still lock it by pressing Start and then lock or by press and hold the power button and choose the lock phone option. So one would say that it's still operational, so why bother about it, but I kinda liked the standard function and I have to freaking idea why it changed!!!
I'd be most appreciative if you could offer some help with that.
Oh, I forgot to mention. Soft reset didn't solve the problem. Erasing the calendar event didn't either.
My phone runs the factory ROM (1.66.482.1 ELL), I haven't changed anything other than user settings (yeah, I'm a noob... )
Thanks in advance!

Pocketshield could be the end of your problems. You can try it for 10 days and see how it goes...
But why do I need to buy third party software in order to revert my phone to it's original operation?
No, this is not the answer I am looking for. I was wondering if you know of any kind of settings that might have changed by accident and caused this undesired behavior.
Thanks.
The best to return to normal operation would be a hard reset. Or you can spend a while trying.
You can try
HKLM\Software\Microsoft\Shell\Lockscreen\Enable=1
HKLM\Software\Microsoft\Shell\Lockscreen\Active=1
Thank you very much. I opted for the hard reset option... I hope it stays ok this time!
My HD2 also had some strange unlocking and unwanted calling.
I noticed it appeared when using the android style lockscreen.
When I changed back to the original one, problem solved
i had this too. the andriod lockscreen seems to be a bit buggy last time i used it, i accidentially called 7 random numbers
I am using the European Tab, but that probably makes no difference.
For security, I lock the phone automatically after 3 minutes of inaction. This works fine for all apps except phone. Strangely, after dialling (or after picking up a call) the phone first turns off the screen, and briefly thereafter locks the device, within 10 seconds. I can continue the call, but as the screen is off, I can not hang up, unless I first switch it on and enter the password.
I have not found a parameter to influence this behavior. But I know it is not related to the proximity sensor, as the effect happens the same way even when not moving the device from the desk.
Is this a confirmed behavior or does anyone know a cure? It's ok if the screen goes dark, and even if you must turn on via power button, but the password?!
Thanks for any help,
Rolf

It happens to me lately after I flashed a new Rom but I highly doubt that has anything to do with it...it feels like a proximity sensor issue, and a autolock issue as well . I am Clueless sorry
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
