Possibly the contact, which is used to detect if the keyboard is open, might not be working.
Mikechannon is the hardware guy on the hermes and im sure he will come across this post at some point
ok thanks but the thing is that i didnt replace to i guess the guy who did it is goin to have to fix it
Hi
I don't have one opened up in front of me but yes Mrvanx has it I think. One of the multi connectors is either un-plugged or not pushed in fully. There is one that is quite liable to "pinging" off unless it's firmly pressed home. No guarantees but I'd be fairly confident that that's all it is. The guy should have checked it after the repair!

This is the likely culprit. It's easy to forget to press it home as it curls itself round on its mylar cable and rests on the connection (ie looks connected but may not be pressed into the connection). Good news is that it's not a major dismantling job. All it needs is the back off to reveal it.

All is lost...

My TouchDual has just lost all touch sensitivity.
Theres no responds whatsoever(Only the hardware keys work).
So what now?
Is there a others that have had the same problem?
Theres a part of the screen, that started to lose sensitivity.
And now sadly the whole screen stop responding.

A copy-paste: You can get a new screen here for $60,- http://cnn.cn/shop/touch-dual-p-2277.html and a nice tutorial that shows how to take your dual apart: http://www.pdacenter.ru/razborka/razbor_htc_touch_dual/
You need only new touchscreen.
It's more cheaper than whole display.
Those are attached to eachother, i guess you can't buy a seperate touchscreen
man send it to HTC for repairs... i have a pharos that had the same problem... took 3 weeks and my touchscreen works again..
you need a 'digitiser' or 'digitizer', it isn't attached to the LCD, it's seperate
try emailing: http://myworld.ebay.co.uk/easyworldwidetrading/
Thanks for the replays.
I dunno what kind of magic/bruteforce, that got my dual working again.
But at the moment my touchscreen is working again.
Tho it still looks messed up(The LCD is fine and looks perfect).
And sometime next month i´m buying a Touch Pro.
So until then i don't want to mess whit the phone.
Maybe i´ll send it for repairs(warranty), and see if they will repair it for free.
I got a new digitizer off ebay, and some tools from www.mobilefun.co.uk.
I have just assembled my Niki, and it works.
Thanks so much for the help.

Some people had it fixed under warrenty, others couldn't because it didn't fell under the HTC warrenty. Very strange indeed.
It is a common problem that appears if you carry your phone alot in your pockets.
Have no clue what to do about it. You should try the local HTC sellingpoint or the shop where you bought it.
You're screen is out, i had the same problem, i did must to change the screen.

HD2 vibration stopped working !!!! [FIXED] WITH PICTURES

Hey everyone
Today I realised that my HD2 vibration doesnt work, I dont know why and what happened but it doesnt work, the only thing that I can say and hear is the click that I can hear whenever I try to turn on the phone , it seems its trying to vibrate but cant , only one click and the phone boots up normally , everything else works fine , I can also hear the click whenever I recieve a call or text .
What can I do to fix it ?
Basically I could fix it, the problem was flash cover, camera flash cover or glass as you can see in the picture had been pushed in a little bit and because it is exactly on the vibration motor itd prevent it to work

So I opened the phone and pushed it back , now its working
I fixed it, and edited the topic coz thought it might be useful as this might happen to someone esle
cheers
Nice fix. Did the cover or it's supports break, or did it just pop out of position?
It wasnt loose, so probably something from outside caused it pop out of its position.

Broken digitzer (HW Design Fault?)

The band is easily visible. It explains my problem. The rest of the touchscreen works fine.
Only noticed over the past week or so that typing on the keyboard in certain spots while in landscape causes two keys to always be hit instead of one.
I remember reading a thread earlier were people had many problems with the touchscreen. Should I ask the warranty service for an s4 or 2013 moto x instead? I don't want this happening again.
Edit:
Them seems to explain it PERFECTLY:

I've had this issue happen to two LG G2s, if you look at the dead band it seems to line up perfectly with the power button on the back of the phone. It seems to me that pressing the power button is putting force on the digitizer from the back and 'killing' that section of the touchscreen. I've swapped the entire internals of a phone to a new digitizer that did not exhibit the issues so I don't see how it could be software related.

I'm not getting another G2.
