[Q] HD2 screen light will not switch off - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Please help!
Since yesterday, after plug off from loading, my HD2 (German t-mobile ROM 1.77, Radio 2.07) doesn't switch of screen. In the past week, I haven't changed anything or installed any apps.
By pressing 'off' key, screen becomes black and will be revoked with screen lock after few seconds. When screen light gets low after predfined time, it will come back will full light after few seconds.
I've tried hard reset, installed stock ROM from t-mobile (include radio ROM) - nothing changed.
Does anyone can help?

I've seen this issue periodically here on the boards. From what I've read from the users who experience this issue, it is likely to be hardware related. One way to test this is to turn off the screen when the device is plugged in (charging)? If the screen will stay off when plugged in then I have some bad news.
The only solution I have seen is to send the device in to HTC for repair. Sorry.
I believe it has something to do with the micro usb being defective.
Hopefully someone will correct me if I'm wrong.

Many THX, the device is within warranty and I will request for repair.

this sounds like the "car kit mode" hardware issue.

Look at the end of the thread for the reason it is happening, and you will need to have it repaired or replaced.

Device has been repaired/changed by t-mobile Germany without any reservations within 48 hours.

[Q] HTC HD2 screen has become yellowish

Hi,
My HTC is giving me problems. The screen has become yellowish.
Earlier the screen used to become yellowish for 5-10 mins and it used to occur in two weeks or so. But now the phone has permanently become yellowish. I am also attaching a picture along with this thread. As you can see, the areas in the pic which are bluish is showing the true color of the background. Rest of the screen is all yellowish.
Can someone help me with this problem.
Best regards,
MOhit Goyal
Looks like a faulty contact from your Motherboard to your screen (bad connector, bad flex-strip or something like that)
IMO you need to send it in for repairs.
I have had the same with my p3300, but was able to fix it myself (connector was not completely pressed down, had come loose)
Hardware problem?
Do you think this is a hardware problem?
Why I doubt that is because:-
1. Whenever I touch any place on the screen for opening an application, the area shows the actual color, but if I just touch the screen the colours doesn't change.
2. Usually the phone starts displaying the correct colours after a restart
Should I take chances and reset my phone or something?
I'm having the exact same problem every now & then (often occurs when I keep the phone in my jeanspocket) A light tap on the screen often helps. Had it in for repairs earlier, but they only re-flashed it (!) So the problem is not solved
What to do now?
I am not able to play any game. I hate looking at my phone. It makes me so angry.
How do I get it fixed. Its the fourth consecutive day with the wrong colours.
Someone please help.
Performed a hard reset but still not working properly
This is not happening. I performed a hard reset thinking that it might just work but it did not.
Can someone please help me here.
Of course it is a hardware fault. Send it in for repair - or repair it yourself
I think is a virus or something else, because has happened to many people lately.
I also had the issue as pictured above.....and exactly as described in the first post.
It began to occur about three weeks....and gradually was getting worse.
Its getting worse
Again I am doubtful that its a hardware problem.
Now, I am not even able to open anything on my phone. I keep getting thrown back to the main screen. No matter what I open, what application I am using, it just keeps throwing me back to the main menu.
In addition to that, even when I am not using the phone, it just keeps flashing. I lock it and the screen turns on again. Its like the phone is getting used every second.
I think its a virus. Does anyone know any anti virus solutions for HTC HD2?
Thanks,
Mohit Goyal
i got exactly the same problem - check my photos here http://forum.xda-developers.com/showthread.php?t=716002&page=2
i donth think it is a virus - why? - becase if it so the virus should go when you reflash the rom or flash a new rom - i douubt also about the virus but when install new rom the color issue still existig.
i sent my device to the dealer for repair and i will apdate you about the real reason when i got the answer from the dealer.
however, the same issue happened before to one of my friends and the device was out of warantee - he took it to a repair shop and they told him it is a kind of default in the mother board.
this time we will get dealer answer so lets wait.
thanks
a member in other forum advised me to use the attached cab which solve a similar issue in Blackstone.
but it is too late for me because i returned the device to the dealer
however- other member faced a similar issue and the dealer told him it a default in the motherboard.
Send in for repair......

Listen to the others... You need to send phone in for repair... My phone use to flicker on and off to the point where I couldn't call or use.... I sent to be repaired and they replaced the mother board, but didn't fix my other problems (phone will not turn off and when u put in battery phone turns on on it's own)..... I would send in for repair.......................
htc contacted me an inform me that the reason was the motherboard
yea its the motherboard isue i droped mind and d screen has changd its colour to yelow blue and sometimes wnt wake up aftr remvng 4m poket.gave it htc repair center they said a socket or conector has a problm whch cnt be repaired and so mothrboard needs to b changed.motherboard cost 8000rupees/190dolars whch is **** expensive for repairing
I had this same problem and read on some other forum that you're supposed to "flex" the phone. So I bended my phone a little (the top and bottom backwards, be careful the screen also has glass in it) to try to get a bit of a curve in it and by god ...it worked!!!!! The screen flickered and then the yellow screen was gone!!! I'm so glad because I mailed Htc two days earlier and I still don't have a response from them. I hope it works for you
Just to confirm... The same thing happen to me its either (A) the cable from MOBO to Screen came loose usually by flexing or bending the phone which can happen in someones pocket. (B) the cable connector came loose by same methods (C) MOBO went bad usually by same methods. Either way one should it in for repairs or crack it open and see for your self.
I got same problem before, it happened when the screen is moist. it looks like there is an absorbent layer behind the screen which got damped. try drying it.....found article to contained the unit in a seal container with rice overnite for drying electronic gadgets, and see the result.remember to take off the battery. good luck.

[Q] Freezing HD2 after lock

I know there are hundreds of threads and articles posted about HD2s freezing with the lock screen but this issue seems different to me. My problem is that whenever I lock the phone the touch screen will freeze entirely. I thought a work around may be to install a different lock screen. After installing that I can get past the lock screen but the touch screen still is not responsive. I have no idea what to do. I already did a hard reset and it still does it. I would like to add that it is completely consistent. It happens every time without fail. In order to even use the phone I have to pull the battery and I get one use out of it before it locks and I have to pull the battery again. Does anyone have any suggestions? I would really appreciate it..
Update: I flashed the original ROM to my phone and the freezing problem still exists.. I have no idea what to do at this point.
Update 2: Narrowed down the problem to being the physical "power/end/lock" button. If I slightly press it but not fully it will go to the honeycomb style menu with all the apps. If I press it fully the screen will go out like normal but then if I restore it, the entire screen is locked up. Nothing will work after that until I pull the battery.
I've directly linked the issue with the power button. I dont know why all of a sudden the power button would have a different function. The work around I found is while the phone is locked and the screen is off I can press the green button to unlock the phone and the touch screen will then function. If I use the power button it will remain frozen. Any ideas what happened?
Hello,
I got some bad news for you, this issue is actually related to the digitizer (hardware) not software. What i would recommend is called HTC for a repair and send it in, it is covered by warranty, hopefully you have warranty.
A lot of people are having this issue, no-one yet has been able to pinpoint the cause, but here is the link a thread with similar problem:

Thanks for the reply. I do not think I have a warranty on this phone considering I bought it privately. Ill talk to Tmo and HTC and see what I can do. Just a theory, I may be wrong. But I live in PA and its been getting below 20 here lately. I noticed today that my work around didnt work when I was outside working on my car. Then I went inside and used a blow dryer to heat up the phone and it started working again. The end button didn't function properly but I could unlock the phone with the green send button. Perhaps the cold weather is shorting out people's digitizers? I don't really know how they work so that's why i said its only a theory. I bought this phone in the spring and didnt have an issue until now when it started getting really cold.

From sleep to lockscreen LCD blank problem,any solution?

Hello.
When I leave my phone in sleep mode (screen locked and light off) and try to wake with On/Off button, sometimes I get a black screen with a faintly image. The touchscreen works and all the buttons, and if you click 2 times On/Off button - the image appears all ok. I tried to flash another stock ROM - all the same. Then I`ve unlocked the bootloader, rooted the phone and even did the S-off with wire trick (1.53 Hboot). Then I`ve tried 3-4 custom ROMs with 6-7 different kernels, from stock to custom, but all the same. Yes, I`ve updated the firmware file, also, but with no difference.
Well, I see that this problem is not so usual, but I couldn`t find any real solution. Did anyone have this kind of problem and solved it? Since I got this phone from another country - official warranty is out of the question, I need a DIY solution.
Any help is greatly appreciated.
THX in advance!!!
I would have to say it looks like the light for your screen is dying, I had my screen replaced once, my screen would flicker from very dark to very bright

hmmmm, but when I get the OK image - it doesn`t flicker or go from dark to bright, it only has trouble to "wake up from sleep mode". even when i relock the screen quickly and don`t leave it unused for 2-3 minutes, the screen works OK every time....it looks like a software problem, but still I didn`t manage to fix it with all the ROMs/kernels/firmwares I`ve flashed....

Thinking about how to troubleshoot if hardware or software. When in sleep mode, instead of using the power button, I would have the phone plugged into a computer and use the " adb reboot " command to reboot the phone without touching the phone a few times and see if it lights up correctly. The first thing you should see is the boot screen, and if it works every time, then you do have an issue with your firmware. If you don't see that boot screen first every time, then as much as it sucks, I would guess there is a hardware issue.
Good luck, but this is the easiest way I know of to help determine what the issue likely is.
Minor update here, the first thing (at least on mine) that I see is the lock screen for just a quick second or two, then it quickly goes into the boot sequence. This is important as in "sleep" the ROM is running, so if the first thing you see is the boot sequence every time, and not the lock screen, then it points more to a software problem than a hardware issue. CM9 had an issue for the epic4g where you had to turn it off and on sometimes to get the keyboard to light. They found the issue in the firmware causing it.
Just wanted to make this as accurate as possible.
Wow so I am not the only person with this problem. The EVO 3D that I have was replacement phone that was given to me from Sprint from the first EVO 3D that I had which had issues with the digitizer. I received the replacement phone this past Tuesday and it worked fine for two days. It was not rooted and I did install the ICS update. On Friday morning I took it off the charger and went to work, while in the break room the screen suddenly went black and I could not get the phone to display anything after that. The Android function buttons at the bottom will light up but the screen wont, the phone also gets hot even with it powered off.
Long story short, I took it back to the Sprint store where they ordered me yet another replacement EVO 3D. Has anyone had to go through 3 EVO 3Ds or more?

Excellent thinking, I didn't think in that direction. I'll try this tomorow, since I'm not at home. My personal oppinion that it's a software problem but if I did all the above - what did I miss? If I flashed the firmware, ROM and kernel, what else is left untouched that could affect the LCD? Could anyone suggest a good kernel? Or can I downgrade the firmware, since no one had such a problem with GB?
just to inform all - I tried all soft solutions, but all the samo. finaly - I replaced the LCD and everything is OK.
THX all for help

Screen goes black when call connects

FYI - I am posting this in hopes that my experience may anyone that goes through this same problem. My phone is S-off and rooted.
I recently had to replace my screen. I bought one from ebay. You check it out the link below if you would like.
The digitizer flex cable was a little too long and seemed not be positioned where it should be, (too far left or something like that). I made it work and got my phone back together. The screen worked just fine until I made a phone call; upon connecting the screen turned off and would not turn back on until the call disconnected. I was running Viper DNA 6.0 originally when screen replacement took place. I could not find what I considered to be a solid lead on correcting the problem at first. I downloaded a different ROM, the teamEOS Droid DNA, same result. I searched more and seen in someones response, (unfortunately cant remember who), that they thought it had something to do with the Kernel. I downloaded JamieTheMorris's intelli plug kernel. When making a call the screen would turn off but, a press of the power button would make the screen turn on but, the screen would not respond to my touch. I tried using the recommended settings and that make my phone go haywire. So I wiped everything and downloaded Santod's NuSense SIX KitKat 6.0 and sometimes the screen cuts off when the call connects but, the power button makes the screen turn on and the phone responds to my touch.
I do not at all feel or claim that I have solved the problem of the replacement screen turning off when a call is connected but; due to the use Santod's ROM my phone functions and for now, that is enough for me.
If anyone has any more info on this problem, or is able to figure the problem please post below.
Replacement screen that I used - http://www.ebay.com/itm/White-HTC-Droid-DNA-Front-Panel-LCD-Touch-Glass-Digitizer-Screen-Assembly-OEM-/370828275337?pt=US_Cell_Phone_Replacement_Parts_Tools&hash=item5657166e89
Since it has RED menu buttons, I think this the screen for butterfly, hence the possible difference in positioning. I am not sure, just my 2c.
Does it have Verizon or HTC logo?

It has a HTC logo at the top. I know it does not mean too much but; the listing says specifically Droid DNA Verizon, although I was questioning whether that was why the cable was not spot on.

Flashing/flickering/artifacting screen?

(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new
