HTC HD2 Screen Unresponsive

Hello Gents and Gals. I am trying to fix my friends HD2, I flashed his ROM with Energy couple of months ago and all was working fine. He gave the phone back to me saying that it is locked.
I tried unlocking the phone but it seems that the screen is unresponsive, so I flashed it again by going into the boot loader screen "Volume Up + Power Button". The phone stated that it is starting for the first time but the screen was still unresponsive. Any ideas on how to fix this issue? Or do I need to tell him to send the phone back to HTC for repairs?

Sounds like the touch screen died ....
Time for a repair ..
Also this really should have been posted in general , as it is not a ROM release , just an FYI

Aww okay. I'll let him know. Thanks.
I'll post like this in General next time. Tks.

HI, I have now the same problem after ROM Flashed, did you solve the problem by yourself, or really the touch screen died.
Rgds

Same thing with me. I ordered new digitizer+LCD and changed them, but the screen is still unresponsive. Other ROM didn't help.
Some advices?

i seen this happen with several phones, reflash to stock and send to HTC they will repair it for free.

I have same problem,yet my phone was bought 18 months ago...worked perfectly until now.
Can a touch screen get defective after normal usage ?

Yes it can, if your touch functionality of your HD2 has stopped working then your digitizer has probably went out.

Yeah,that's what i thought too - but i read some situations where replaced LCD + Digitizers didn't solve this problem.....

This is usually due to the replacement components not being properly installed. Also when one is working with the internals they have to be very careful as some of the internals are very easy to break without you even knowing you did. So the cases you spec of are more than likely not because it was not the Digitizer or LCD was not the problem, but human error.

i fixed mine and it didnt cost me
the unresponsive screen maybe the digitizer buts its more likey the end call button, believe it or not dirt can get behind the contact or because the back button is next to we use the far edge of the end call button thus leading to bending the contact, when any of this happens your screen will be unresponsive
you can either take it to a shop and pay for a new screen and digitizer or take it apart and clean the contacts
go to ifixit for step by step guides
hope that helps

I have no idea what are you talking about, that doesn't make sense, as far as I know is no direct relation between END button and (non-working/responding) touchscreen: you may even disconnect/replace bottom buttons ribbon/flex from motherboard and touchscreen will work if OK(or not, if defective).
Is there anybody who can confirm this(or not)?

3 weeks ago I had a LCD/digitizer replaced (cracked screen, but was still working) all was great till 2 days ago. Screen stopped working - took it back to the place I had replace the screen and they tried 3 brand new screens and still no go. Ended up being my main board - luckily I had a spare HD2 and they pulled that board and all is well again.
Believe it or not your LCD/digitizer might be fine - find someone or a way to test main board would be where I would start after the last 3 days.
Good luck
PS - I did NOT try the end button idea prior to the repair.

htc hd2 screen died
I also have a 2009 htc hd2 on which screen does not work.
I'd like to know if it's
- a common problem
- is it possible that it's a software (flashing) issue
- can it be replaced and for how much

From my own experience :
1. It's a common issue, there are hundreds of reports in this forum and I read them all because I had the same problem some months ago
2. Probably not. It's generally hardware-related and often the digitizer (touch responsive screen) . Brief explanation : There's a flaw in the design of the HD2, the thin cable wiring the digitizer to the motherboard, is just below the power button. After some extensive use of your powerbutton, it might happen that the power button touches the cable and cause some kind of shortcut in it which makes the digitizer unresponsive to the motherboard.
3. I replaced mine here : http://www.htcphonerepairs.co.uk/ . Fast repair, secure shipping to Belgium, good price and excellent customer support. (Sounds like advertizing but I swear to be only a happy customer )
There are also multiple videos on youtube explaining how replacing the digitizer yourself if you dare !
Also, I read answers saying that you can somewhat "play" with your buttons (especially the power one) to turnaround the problem. That's correct, BUT it's absolutely inevitable that the problem with come back again if you use the buttons, and you'll have to force more and more to unblock again and repeat again and a again... and that will damage your button bar.
I did this during almost 2 months and that put down all my buttons and now they are really close to the chassis which is very annoying. If only I knew it before I would have replaced the digitizer directly !
For 6 months with my new digitizer + using ICS with soft buttons, I have no problem at all !

Just because this dude has "no idea" it doesn't mean he knows it better.
It IS the END button that gets pressed too often and at some point it begins to mess with the digitizer connection. It can be dirt. It can just be the cable came lose and needs tightening, it can be wear-out.
whatever it is, it is caused by the end-key being too close to the connector cable.
If you guys only searched for this on the HD2 Forums before posting this Thread hat not been necessary. It is the most well known design flaw of the HD2 and as such well documented and commented here.

This is truth. Save yourself some time and frustration and repair it or get it repaired. It's a great phone.

You didn't get it right or at all:
END key may determine touchscreen failure along the time(being the CAUSE! of this), but the EFFECT is an unusable touchscreen, which cannot be repaired in any other way than replacing it(the touchscreen!!, I mean).
Any other attempt to repair, clean, bend, press, cut or whatever WILL NOT FIX an already faulty touchscreen (even caused by END button excessive or not usage) and who thinks otherwise, no problem with me: SWEET DREAMS!

You sound like my comment hurt you. Sorry if it did. I'm not one hundred percent sure that this issue can be fixed without replacing the screen, yet fairly certain. I've now disassembled two HD2 and couldn't quite find the precise spot where the damage occurred, yet after properly assembling the devices again, one came back alive, the other not. The one which has the screen and buttons not working right is the one that got thrown at me by a kind person. It most likely has physical damage somewhere, although I couldn't locate it. The other one didn't get damage and has screen and buttons work well after complete disassembly and assembly.
Both devices also have different screen types.
I now gave up both devices and am withdrawing myself from the HD2 world. Too many issues with the devices getting old.

Power button dying

Coming across a problem with my DHD. The power button looks like its beginning to fail. I had it in my pocket and bits of sand and dust were getting into the edge around the power button and it got stuck. I got most of it out but its getting harder to press. Anyone else had this problem and maybe have a solution?

Ok its been a couple of days now and its pretty much useless now. The power button is constantly pushed in by whatever is stuck in there. I have to push it about 10 times to get it on or off. Going to take it to the store after work and tell them to replace it.

Seems like the Power button isn't. Pretty good. Mine is on the left side a bit higher than on the right since I bought it.
But I don't want a replacement, because the phone is sold out in Germany..
If it gives up its job, ill bring it to the store.
Please let me know what they say in the store

Surely taking it apart would void your warranty?

I had a good look over what they would see as voiding warranty and theres just one lil sticker on top of a screw. Not even a security one, u just take it off and put back on.
I took it apart and fixed the problem anyway.

I've noticed my button has gotten tired as well. It seems like it has sunken down and feels harder to use.
I've downloaded an app called "tap tap app" which makes you able to turn on and off the screen by tapping on the sensor next to the speaker on top of the phone. Works pretty well and saves my powerbutton.

saves the powerbutton but drains battery faster
another question: your dhd is built together again?
i didnt find any teardown yet..some pics would be great...
DN41

My power button is fine, but it feels like my volume up button has sunken down since I removed the battery.

i had this but fixed mine by applying pressure on the button for a while and pushing it right in, try using a needle to remove any dirt or grain from it, if your in portsmouth sometime maybe i could fix it XD

Not a sollution, but you can disable the lock screen (i made it cause i really think it was pointless) and use an app to turn off your screen when needed...
I barely use the button, even with no problem with it...

Its actually very easy to take the phone apart and back together again. And since doing so i fixed the problem. Im not sure if it was causing the problem or if it was something else, but once i had a look there was a flat piece of lpastic on the underside of the power button. It looked like it was supposed to be there but i took it off to give abit more clearance and that worked.
Id love to do a guide but my phone is my only camera. Ill see if i can borrow a friends. Or use an old phone.

touch screen not working

So my touch screen hasn't been responsive for the last few days. It's only partially responsive sometimes and not at all others. Has anyone else experienced this or know how to fix it? If not does anyone know if this would count as a manufacturer defect and I fould get it replaced?

For how long have you had it? It should go under warranty.

Is your phone overclocked? Or even rooted?

I'm having a touchscreen issue too. However it only occurs when keyboard has been flipped out. The entire screen's touch capability does not work, including the touch buttons search, back, menu and home. If you close the screen over the keyboard even a little bit. The touchscreen works perfectly. Even if you then flip it all the way back out again it works, until you close and open it again.
Anyone experienced this? Or have an idea if this should just be replaced under warranty?

Sounds like a classic case of bad ribbon cable.
If you are under warranty, replace it. If not, it could be something as simple as replacing the cable the connects the two halves of the phone together.

[Resolved] Touchscreen doesn't wake up properly

Hey y'all,
I am having a weird problem. I have an HD2 wich worked great. Now after some time I am having a problem with the phone waking up. When it's active and unlocked, the touchscreeen works great, but when I turn off the screen and turn it back on, it won't let me unlock it. The touch screen just doesn't seem to work any more.
So I thought maybe relfashing could help. Said and done - reflashed Android > didn't work. Wiped, flashed WP7 > didn't work.
After some time and trying 3457 times, it works sometimes and once it is unlocked everything works well. But it's unusable this way.
Any ideas?
Thanks in advance,
JR

I had this problem yesterday. I bought my phone second hand, it had a brandnew touchscreen, the previous owner dropped it.
after 3 months (yesterday) it started woring really bad. 8/10 times it wouldnt work.
I got my hands on a HD2 which was bricked (epic fail) for 10 bucks and swapped my mainboard. it works flawlessy again. Im guessing the replaced digitizer was a cheap knockoff from China.

My friend's phone has the same issue. Touchscreen works if you wake up the phone by back button, but it does not if you wake up with power button. Did you try that?
The most strange thing is, it is the same when on windows or android, as you said.

Hey there.
After some searching I found out, that the digitizer is messed up. The thricky thing is: The digitizer hardware is located right beneath the power button. This is what is causing the problem (the power button was messed up a little also). So if you are experiencing the same issue - try pushing the power button a little harder. That might make you able to wake up the phone.
I would have to renew the digitizer, wich is a real pain and a lot of work. You'll get a new HD2 for around 130€ and the digitizer costs about 60€ I guess. Plus all the work and the risk of f***king it.
SO - my choice will be a new one. HD2 is just a great phone because of it's community!

or get a bricked on for less like I did. Swapping the mainboard is really easy if you take the time and use the iFixit repair guide. I used a hair dryer to ease up the internals by heating it up and with a suctioncup I pulled the internals right out of the shell.
the copper sticker is a real pain in the ass though... But its doable.
You'll need a T5 torx screwdriver.
Oh and I love the HD2 community no doubt about it

I have the same problem, you think it gets resolved by buying a new digitizer? I was told the problem is not that main board but only the digitizer so not worth the hassle of getting a bricked phone I assume.
Thanks

A nonresponding digitizer can be caused by many things. I´ve heard of the end key messing with the touchscreen controller and vice versa.
I had a replacement digitizer on my HD2, it stopped working and now I have a genuine digitizer.
The genuine screen is just much much much better. It just feels much better. It´s more ´slick´. And less grime attracting.
Look in the general section for people who have bricked their HD2 and PM them and offer them money

Hey guys i have the same problem u think its the digitizer not the flexible ribbon?
now when i press any button nothing happen its like the screen become unresponsive and after hours of trying it unlocks

There is no way you can use magldr since it uses the volume buttons, you will have to stick to windows mobile at some way =/, But I think you can't enter bootloader 2, since you will have to hold down the volume down button.

Not only you can't go up and down,but also flash rom or adjust volume.I suggest you should have fixed it

...or wait for the release of the Magldr touch screen version
but still will have limitations w/o the up/dn botton

You need to replace the soft flex, it contains the side volume buttons. Buttons by themselves are impossible to replace due to the type of connection to the main flex, therefore the whole thing needs to be done.
Like this http://www.ebay.com/itm/BIG-MAIN-FL...907?pt=LH_DefaultDomain_0&hash=item20c261b5cb
Not very difficult to replace, just need to be careful.

If you live in city, you can try to get it repaired may cost you 10-20$

I think we are talking about different things. The side volume flex cannot be repaired, because it is a part of the main flex and the whole thing needs to be replaced in order for volume buttons to work. I know the assembly and disassembly procedure very well indeed. What I had issues with is the suggestion that the volume flex can be repaired by itself for $10-$20. It cannot be. End of story. Sending me links to the disassembly procedure will not change that.

Depends if the cable itself is actually torn or if the volume buttons don't work because the dome contact and the tape came off the flex itself (misaligned probably over time)
I have had this happen to both my hd2's and I repaired both of the volume contact dome/tape with superglue.. all it takes is a toothpick and some patience.. just add tiny dabs of superglue on the corners of the plastic part of the volume button itself and then carefully slide the contact dome/tape onto it, wait for a minute, and it should be good for use.
