Hi all ,

all buttons of my HD2 stopped working & i think my button panel strip is completely dead ...though i am able to boot phone (by plugging the usb cable to computer & removing battery & inserting it again) ..but unfortunately my touch is also not responding ...

My Question is - is Touch (Digitizer strip) somehow connected to button panel strip ? so that bcoz of button also touch is not working ? ...Or Touch should be working regardless of Buttons ?

The problem is ..its very hard to find spares of HD2 here in kuwait & Even if i get one it will be very expensive..so what u guyz advice ? ..should i give it to fix buttons & my touch will magically start working again or Should I retire my beloved HD2 ?

PS: HTC doesnt have even single Service center in entire country ..Stupid HTC ..& Most repair people here in kuwait are dumb as fu**..& doesnt know sh*t abt it ..& one guy who is ready to fix it ..is not ready to take responsibility if anything goes wrong ..so basically m all screwd up

same problem here

my hd2 screen wont work till i press power button hard enough

but soon i will try to change the button

hope it will work :D
[HD2 Android Q&A, Help & Troubleshooting and Genera] ramdesai:
Yes, the digitizer connection is right below the power button. Try pressing hard the power button. Once touch screen responds dont use the power button. Instead use the soft buttons for the purposr.
[HD2 Android Q&A, Help & Troubleshooting and Genera] karthik91:
First of all many of you think that the touch problem is due to keypad buttons.. but that is not true !! since the flat cable of digitizer passes exactly under the "end button" while pressing end button it pushes the flat cable which causes to respond.. but the problem will not be solved..

if you get the touch response problem then you have no other way other than replacing your

DIGITIZER (costs from $15 in ebay - little complicated to fix)

( OR )

LCD + DIGITZER (Costs around $30 - much easy way ) and since u said you said keypad doesn't work u can get that too for around $3 in ebay !! in youtube there is a clear dis-assembly steps so u can even do it by yourself !!
[HD2 Android Q&A, Help & Troubleshooting and Genera] abdealiv:
Thanks for your reply & but Buying from ebay is little complicated from me ..coz shipping to kuwait is expensive from most dealers & they ask for Paypal account which i dont have :(.. & local mobile technicians are asking way too much for fixing it :(..

anyways i will try to find the dealer which has payment option as credit card & has reasonable shipping expense otherwise sadly i'll hv to move on & leave the most epic phone ever & this awesome HD2 community :(

HD2 theory

Here is my thought. I had the HTC HD2 and the screen went out. I noticed in the weeks leading up to that the screen would glitch sometimes, or the phone would do weird erratic things. I noticed that the End Call button seemed to be pushed in more than the other buttons and when I would press hard on it, it would allow me to use the screen for a while. I'd go a week or more and it'd be fine, but that slowly degraded to the point that I had to hard press the button as I swiped my finger, in order to use the screen at all. I realized that the button was involved, but with a lot of mystery symptoms, I think the problem is we're causing a short. The button is slipping (as someone on here said) and it might be shorting just enough to cause erratic effects and essentially burn out the digitizer. I think that is a problem are on the phone where hard pressing both fixes the problem and makes it worse at the same time, quickly killing it completely.

If you seriously want to keep the phone, spend the $20+/- bucks and get both the new buttons and the new digitizer and swap it all out. Refurb the phone yourself and if that doesn't solve it, decide if it's worth further investment in a 5 year old phone. Don't get me wrong... I LOVED my HD2. Very first of the original smartphones that made you go "Man, this is the future and every bit as good as iPhone"... but it's time for us all to move on. haha

5 year Old ??:confused: it was released in 2009 October..which makes it 3 :p
[HD2 Android Q&A, Help & Troubleshooting and Genera] abhi_2691:
guys let me tell you the problem is not with the power button.

the problem is with the cable right under the power button coming out from the digitizer and connecting to the port under the screen.

i am using my hd2 removing the hard ware buttons. Not the internal strip but just the buttons and

i checked whenever the touch doesnt work just touch the digitizer cable and it will work again fine, but for sometime.

In the end the main problem is with the disitizer only.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
Im pretty sure this problem is not caused by the Digitizer. I replaced mine today and it didnt fix the problem. So i think it is caused by something else. Maybe something on the motherboard got fried. Thats the only thing that makes sense for me.

Greetings Bl4ckX
[HD2 Android Q&A, Help & Troubleshooting and Genera] NYLimited:
The HD2 digitizer is a notorious problem. Secondary sources of touch screen failure include the touch screen itself and, as you suggested, motherboard.

Sorry, no simple solutions.

First my wife, then me had similar problem in less than a week. Nothing seemed to help it, even pressing the power button stopped working after some time. Both phones were as good as dead, we considered order of 2 new digitizers or upgrade option. Yet, here is something strange: If I connect any of our HD-2s to the comp and select Active Sync as an option, the screen works just fine until I disconnect and lock the phone. Kinda strange...:eek:
[HD2 Android Q&A, Help & Troubleshooting and Genera] jkflor:
wow .. my screen has been acting up. Been having to press power button hard to get screen to work but that stopped working today. I saw your post about connecting to pc so I tried it and now screen works.... very odd

conclusion

Ok here I am, late but here. As mentioned here, the electrical tape is very important. it's a conductive tape. I found it on e-bay after trying to put my HTC together. Finally after carefully reassembling it I got it to work with all the buttons and the same digitizer. Touch screen responded well, and the buttons too. However I recommend replacing the digitizer too if you will open the phone anyway, but just to see if I was right, I did not. In my case it worked well for a week... Unfortunately a week later it had a gravity problem. I blame Isaac Newton for this. I dropped it and broke the screen...:crying:
[HD2 Android Q&A, Help & Troubleshooting and Genera] dragonsuicida:
In your case, but in my case it was the power button, as I mentioned before, the orange cover that protects the contact plate on the button is very weak. After thousands of times of pressing the button it breaks. Which was my case. So the problem was the power button...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Red-Dog:
So just to un-confuse myself a little, did you replace the plastic buttons? Or the buttons ribbon cable? Because I replaced the digitizer on my phone and still not working so I'm thinking it is the button problem. And I noticed you said the orange cover breaks? That is on the plastic button panel right? So I am now wondering what you ordered on Ebay, the plastic button panel, or the buttons ribbon cable, or both?? ...lol Also could you post a link of the electrically conductive tape too, i have been trying to find what kind to buy...
[HD2 Android Q&A, Help & Troubleshooting and Genera] nyvram1:
not that this helps..but i love my HD2 so much i've actually taken it to a very seedy little phone repair place to fix cracked glass TWICE.

the first time i took it i tried to explain about the button failing and they waved me off "WE KNOW WE KNOW WE KNOW..WE FIX IT"

and they did. an hour after walking in my phone was ready and the button issue never happened again.

i just replaced my glass again 3 days ago..and now that i'm running android, i'm using the volume button to turn it on and avoid the hardware buttons completely to reduce the potential for it to return.

but my point is, they fixed my first cracked screen 2 years ago..and they fixed the RED BUTTON issue at the same time..and it has never come back.
[HD2 Android Q&A, Help & Troubleshooting and Genera] NYLimited:
Do you mean to power up the device or to turn the screen on?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
All these things with the power button, are confusing me.

If the power button would be broken, you should not be able to turn the screen on or off.

But this is actually working.

In my last post I said that the new digitizer was not working. The same evening a friend came over and while we were drinking a beer and were talking about some stuff, I mentioned my phone and that my repair failed. He took it and asked me what I was talking about. The screen was working. And since then it was almost always working. Only a few times it was not working. Since this morning when I came out of the club it has stopped working completely. It was working at the beginning of the evening but I haven't used the phone since then anymore. So this is still extremely random when this happens and I can't find any pattern which could cause this malfunction.

I think I am going to go and buy me a new phone. Maybe the Sensation or the Sensation XL, since my budget isn't the biggest.

I am just a poor student. :D :(
[HD2 Android Q&A, Help & Troubleshooting and Genera] nyvram1:
didnt mean to confuse the issue; my issue was using the 'red' end call hard button would lock my screen..the screen wouldn't respond if someone touched that button.

i got so used to never touching the red button that i would hit the roof if a friend picked my phone up and touched it locking my phone screen up.

i could do the 'green button red button' see saw at first to get the screen going again..sometimes it would take 15 minutes before it would come back..rebooting didn't help..it was a hardware failure.

so fixing the red button issue fixed my screen issue. make sense?

AW: FIX for HTC HD2 touch screen not responding

Well this is exactly what my problem is, but as i said, it makes no sense, that this is caused by the power button, because the button is actually working. I think the hardware issue is some kind of a chip, that turns the screen and the digitizer on and off. Maybe the turning on off the digitizer is not working correctly.
[HD2 Android Q&A, Help & Troubleshooting and Genera] nyvram1:
Yep same thing. It's the red button that is the culprit. As long as you don't touch it the screen works.

Do this.. Next time it locks the screen push red button gently.. Then green button.. Then touch screen.. After 10 or 15 tries the screen will come back.. But without the hardware fix this eventually will stop working.

AW: FIX for HTC HD2 touch screen not responding

So guys I replaced my buttons a minute ago. I ordered a new bar (not the black buttons) on Ebay and as i expected it is still not working. I just wanted to test the last thing that could fix this before I buy me a new phone, but it didn't help either.

R.I.P good old HD2 :(
[HD2 Android Q&A, Help & Troubleshooting and Genera] ripter1:
I dont think this is a hardware issue. My touch screen is completely unresponsive until I pull the battery and boot into ClockWorkMod and re-install the ROM. After doing all of this, the screen works flawlessly until the screen gets locked again...then no response what so ever. I've used 2 different ROMs so I'm fairly sure its not the ROM. Hmmm
[HD2 Android Q&A, Help & Troubleshooting and Genera] babaros:
possible hardware solution

i have found a posible hardware fix. anyone who have this problem (by pressing hard red buttom gets his touch to work and then the problem comes back again) should try this: remove the the panel with buttons not the flex. turn on phone and if touch works i will post you the final fix for this "bug". kisses from greece.. see ya ;)
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
AW: FIX for HTC HD2 touch screen not responding

Do you mean the black panel, or the electronic one?
[HD2 Android Q&A, Help & Troubleshooting and Genera] babaros:
i mean the black panel. remove it and try the touch. if works i will tell you what to do next:p

(go to ebay and type into search the item number :120748678116 to see what to remove)
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
I'm going to try this out now. I'll let you know if it worked or not.

But one thing is sure. If it does I owe you a beer :D

Edit: It does not work even after removing the black bar. :/

But would you mind telling me anyways what I would have had to do, if it had worked?
[HD2 Android Q&A, Help & Troubleshooting and Genera] babaros:
;) i hope it will work for you as it worked for me. i broke my first hd2 mobo and please be careful.

then i bought a new one and after months i find out the solution. now i have an htc hd2 t-mobile fully functional!!!!!

i would be thankful for a beer.... anyway try and post me the results to guide you.

---------- Post added at 06:37 PM ---------- Previous post was at 06:06 PM ----------

sorry... your digitizer died... anyway :( here it goes. Your digitizer has a flex on the right side (red button on panel) exactly where your black panel is. (the black panel is between digitizer and digitizer's flex) when you press the red button you also press the flex so after many button kicks the flex barely disconects from your digitizer. and if you continue using the phone with this problem your ditizer dies :( but if you did it when the problem began you could solve it by cutting the edje of your black panel on the left side. so when you press the red button you dont push the flex and everything works fine. now you have to buy a new digitizer and will work without cutting the black panel. but... after a few months you will have the same problem. to avoid this cut the black panel emediatly when you place the new digitizer. hope i helped you.....

AW: FIX for HTC HD2 touch screen not responding

I'm pretty sure this is not what caused it in my case.

My digitizer is just 2 months old and I only used the phone for 3 weeks. But thanks anyways. :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] babaros:
would you mind to tell me your story with the phone? in case i could help you.... :rolleyes:
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
So I got mine about one year ago from my aunt. She got a better phone within her contract and didn't need her HD2 anymore. So she gave it to me. When I had the phone about 3 quarters of a year the problems started. I had been using the phone without any problems with varios OSes before. Then I ordered me some screen protectors. And then the problems started. The second day after I was using my HD2 with the screen protector I was noticing something strange. I was still in my bed and tried to answer the messages I got during the night and for some reason my phone wasn't responding. First thing I did was taking the battery out. Helped once. Then I took the protector of. Didn't help. Then I noticed, when I put the phone on the head and unlocked it, it was working. Then things got worse. At Christmas I was only able to make my HD2 usable again, when I was unlocking it using the green button or by hard pressing the red button. When I was together with my family on Christmas I spoke with my aunt about the problem and she told me, that she had the same problem about one year before. She gave her's back to her carrier (Vodafone) and got a new one or a repaired one. She couldn't tell me what they did, but afterwards it was working again. She told me, that if I would restore the stock OS on the phone and give it to her when we meet the next time, she would give it back to Vodafone again.

Then the disaster happened. I was in the bathroom and had my HD2 with me and got a message. When I wanted to pick it up I dropped it. It slammed on the floor with the screen. The digitizer broke. In this state I couldn't return it. So I bought me a new digitizer and repaired it myself. The first day after I had repaired it, it was not working, but then it was working almost flawlessly again. Only once in a while the screen wasn't responding for half an hour or so. This lasted for 3 weeks. Then it became completely unresponsive again. I tried changing the buttons. Didn't help. And this is where I am now.

And my aunt thinks I found a workaround for the problem and I am using the phone still. I never told her what happened. :D
[HD2 Android Q&A, Help & Troubleshooting and Genera] babaros:
At first problem when was on your aunt's hands the solution 99% was what i told you about panel. But now the problem may be the screen also. I say that because screen is between touch and mobo. Have you changed the screen? I believe that the drop caused your newest problem and trying a "Full Touch Screen Digitizer + LCD Display Assembly hd2 t-mobile" ready to replace would solve your problem at all. search on ebay is the first on the list.

But if you also tried that solution it is definitely your mobo :(
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
After I dropped the phone I bought one of these LCD + Digitizer sets. And as I said, it worked at first.

But not anymore. I'm pretty sure the problem is my mobo :(
[HD2 Android Q&A, Help & Troubleshooting and Genera] wippie:
Problem is quit simple.

Digitizer and LCD are 2 different things that going through one cable. So, the main cable with LCD and digitizer is hurt by the power/hangup button (design issue?)

So, buy a new digitizer + LCD for $30,-, problem solved.

AW: FIX for HTC HD2 touch screen not responding

It's quite hard to read, right?

I think I already mentioned it three times, that I already did that but it didn't help.
[HD2 Android Q&A, Help & Troubleshooting and Genera] dr_ggm:
Same problem ... strange fix

I have the same problem of touch screen not responding to touch with my HTC HD2

but it does not appear when pressing the red power button

it appears when I clean or wipe the screen

YES, when i clean or wipe the screen while the phone is locked ... no matter what button i use to unlock the phone ... it does not respond

BUT, when I remove the battery cover at the back and put it back, the screen works and responds just fine !!

I removed the 2 nails in inside of the cover, suspecting that they was causing then problem, it got a little better (let frequent freez) , but the problem is still there

I tried to replace the back cover with a new one from another mobile, first the problem disappeared and the phone worked just fine even when wiping the screen, but after a while, the problem it came back again

The screen with the digitizer were replaced before because of the same problem

I think this is a flaw in the design of this model

Any suggestions ?

[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
That is interesting. If I had reassembled my HD2 properly I would test this now, but I have to do that first and at the moment I have no time. When I'm done, I am going to tell you if this helped me or not. :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] dada.81:
OK, I'm confused now :silly::silly::silly:

Is there a way to determine what exactly is causing HD2's touch problems please??!

I've used two different ones, one being an HD2 with (what I though was) a faulty mainboard, and another's mainboard that (again I thought it had a touch digitizer problems)....but when I assembled parts of the two into one, I'm still having a problem with the touch, so is there a way to make sure that replacing the digitizer with a brand new touch+lcd assembly will help....I wouldn't want to be buying a new lcd+touch if that's not the solution to my problem?

Is there a way to make sure that my old touch+lcd was still working, or that mainboard is not at fault, beucause I've tried using multiple different ROMs with only occasional touch response (that lasted at most a day)?

TIA
[HD2 Android Q&A, Help & Troubleshooting and Genera] Bl4ckX:
Sadly the only two ways I have left to tell are first to teach your Phone to speak to you what it's problem is, which I think will take some time or second to replace everything to find it out. I would try the second, it looks a bit more promising to me ;) :D

I would love to know what my HD2's problem is but you can't rely on solutions people have in this case because it seems that there is a different one for everybody.
[HD2 Android Q&A, Help & Troubleshooting and Genera] soulforger:
Permanent Fix!

Well, i think i managed to fix this problem permenantly!

Problem:

While i was installing and configuring Facebook Home App , my touchscreen had stopped working suddenly!

I tought that there was a software problem. I rooted the phone but no luck. Then logged in to Xda and found this topic.

Then i did the power button trick, and realized that the yellow refresh button at the back does the same effect.

But these were not permanent solutions.

Today i decided to open my lovely Hd2. And after many hours i managed to fix.

Observation:

In my case, that was not about buttons flex cable. If the power button stuck or something , it wouldn't work, right? But it was working.

I dissasembled the Hd2 watching that video:

http://www.youtube.com/watch?v=YdOC3Xxo_k0

But be carefull! You can damage the flex cables.

After dissembling i tried many ideas. But at last i noticed the main problem starting up android without buttons (plastic thing)

When i touched only the power button on the flex cable to lock and unlock, touchscreen worked perfectly.

But when i touched to the flex cable which goes to digitazer, touchscreet stopped working.

And touchscreen stopped only when i touched that cable from the top.

I saw that when we press the power button, it touches the digitizers flex cable and it disconnects from digitizer.

Solution.

Unfortunately i couldn't take photos. But i will describe.

When you open Hd2 to the last part, you will see that flex cable.

Sorry for poor drawings:

Take an old credit card or something like that, cut the card and fit to the bottom of flex cable.

When i started to assemble i relaised power button stuckes there hard, decided to cut with a sharp knife.

That way button would less touch the cable.

But be carefull and wise! Don't cut the part which appears from outside!

Before you start to assemble try that everything is working! Assemble important parts and try.

If there is a problem, try to fit that piece of card differently. Maybe smaller, or bigger, or deeper to the digitiser.

In my case it worked, pressed the power button very hard, tried different situations many times.

Button feels harder to press, but not disturbing.

Important

Disassembling and assembling are very hard for many people. Try if you trust yourself or did this before.

I hope it works for you too.

Thanks.:angel:
[HD2 Android Q&A, Help & Troubleshooting and Genera] Realalist:
Well this solution worked for me, somewhat, but I bit to hard and cracked my flawless HD2. But I'd rather have a temporarily cracked screen versus and useless phone.:o

Question is; Outside of the screen what other parts need to be replaced to get my touch screen working like new again?:confused:
