HD2 Touch Screen issue

Hi all,
Recently had my HD2 fixed due to a horrendously cracked screen...
However I'm now having some issues with my touch screen
Basically it was all perfectly fine until about a week ago, then I couldnt use the touch unless I pushed in the bottom right hand corner and now it wont work at all...
Anyone got any ideas on what I could do? The guy who fixed it believes that its a dodgy part but I don't really believe him...

sounds like the ribbon cable from the screen to the mainboard has been either bent/creased/split/not re mounted correctly.
I'd be getting a second opinion and billing the guy who fixed it.

thank you,
I took it back today, complained about a couple of things, like the screen/glass not being plush in the device (if you can imagine that the buttons at the bottom were not raised that's about the height I mean) and there being dirt between the LCD and the glass.
Also brought along the old LCD to draw some comparisons and I think your suggestion was correct:
On the old LCD the cable is glued to the back of the LCD screen and the screen was fitted as expected...
On the device now the screen is raised and the cable is loose, can only assume that its not connecting with something on the MB?

yea sounds like its been badly put back together. make a fuss would be my suggestion. not sure what else to suggest.

Who did you take it 2? I need to get 2 HTC HD2s fixed

Unresponsive touch screen :(

The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..

am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered

I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?

I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.

I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.

Nah.. I dont think its because of widget locker.. its the digitizer..

well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...

I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?

Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.

I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?

I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.

My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.

My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.

I still recommend the same thing that i posted earlier here, her screen still works perfect.

I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.

I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.

Touch screen big issue : nearly not usable

Hi all !
Since a few weeks/months, I have my touchscreen which becomes less and less responsive. In fact, the issue is that sometimes (say one push every 5) the release is not detected, meaning that my finger is still detected while it is not on the screen.
This does not seem to be software related as I have same issue with different ROM (Cyanogen, MIUI...). Also, I changed the touchscreen (bought on eBay) and I still have the same issue...
I tried with different positions, for example touching the edges with my other hand, or opposite letting the phone on the table without any other touch than my finger, but issue is still viewed on the same rate.
Any idea ? Anything to try to fix ?
Thanks !

You haven't recently installed/changed a screen protector, have you ? Some of them make the screen a lot less responsive.

I had this problem during winter but everything is OK now.I am pretty sure that it is the cold weather that confused my device.Maybe you can have a test on different temperture.

Thanks both of you for your answers !
No, nothing changed : screen nor case. And temperature does not seem to resolve anything... I also have bought a new digitizer, replaced it, I still have the same problem...
Maybe a grounding issue ? The digitizer connector ?
I'm afraid I'll have to buy another one... maybe a broken one, with different issue...

[Q] Grey screen - display problem

Hi,
I had a small accident today with my HD2 . It felt from my pocket to the hard floor. It was in the leater pouch, but it hit right on the corner, where is no coverage.
I picked the phone up and was happy at first (no display cracks), but not for long. When I tried to turn it of, grey screed showed.
The device seems to be working, I can turn it on/off with the HW button...but I cant see anything.
As I said, there are no cracks of the glass layer so the digitizer should be ok. I just don't know actually.
Can anybody help me?

unfortunately you cant make that assumption, i have a hd2 with a badly shattered glass, (same as you, dropped from about 3 feet landed on the corner, shattered all the way to the other end of the phone) yet the digitizer and LCD worked perfectly for at least 18 months before finally the digitizer died, LCD still works fine.
My point being that just cos one part of the three (glass, digitizer, LCD) seems ok tells you nothing about the other two parts.
My guess is either the screen itself died, the connection on the mainboard broke/became unseated, or even that its unrelated to the screen at all and is in fact something else that broke and shows itself as a non responsive screen.
Im not sure if this is possible given that you have no screen to work with, and i guess something would need to be installed on the phone to make it work, but how about some software that shows your screen on the PC? you may even be able to tell if touching it is working.

Some help trying to fix a Motorola Defy?

Hello, I have a Motorola Defy, that I dropped a few times, so the LCD screen got damaged with blue dots on it, I made a mistake and thought that the problem was on the touch Screen, so I purchased a replacement, installed but, it was damaged, the touch did not respond correctly, I wasn't able to type correctly among other problems.
I got a refund, then ordered a LCD screen replacement, now that I have it here, I install it, and it's broken:crying: I know, bad luck and being a rookie while trying to fix my phone, ok, I put back my old (damaged) LCD screen to use it in the meantime, and the old touch screen, but now, the old touch screen that was supposed to being working fine, it doesn't, it has the same problem as the touch screen that I bought.
Question is: the problem with the touch screen, could be related to the damaged LCD screen? or the motherboard of the phone is damaged? the phone works great, the apps, the games, everything but the touch screen and the LCD screen, but, as I said, I went back to the default touch screen after using the damaged one that I received, and it works worse I don't know what's wrong, please help me out, sorry for the long post

Please post questions in the Q&A section. Moved there.

Is this true?

true. fix some minor dead pixel if you put in freezer for one day. but your case... im dont hope much.

Try changing LCD + Capacitive Digitizer. (after trying the freezer trick ofcourse)

Well i will tell my story, which is related to your's as well,
i had a phone with resistive touch screen and it got screwed up, that is it does not respond correctly. So, i took it to the service center and they replaced the digitizer (touch screen) saying that previous one is broken. But, luckily the new one didn't responded to any touches they make.So, they replaced it again with the old one quoting that "your phone can't be repaired". So, i took it home with me.
Later i thought to calibrate the screen but the old one is not responding any more, no matter where i press
Later i calibrate it with the help of a software for windows mobile with the help of a PC. It took me to the calibration screen, from where i calibrated it, and voila, it worked... as good as a new one :victory:
long story short,
i think when you disconnected your digitizer, phones default values/drivers got messed up and are unable to find the new or the old digitizer you connect. I suggest you to go to the service center as these screens can not be calibrated.

Is there NO WAY at all to recalibrate the screen from the phone itself? or using an application? the delicalibration might be the problem....I'd like to fix it myself :/ thanks for the tip, never heard about it before!!

I replaced my original digitizer screen for the one I ordered it, it gave me problems, so I went back to the original one, which was working fine, and now it's not fully responding, that's why I'm assuming is something calibration related, thanks!
