[Q] HTC Sensation hangs on bootscreen after touch screen digitizer repair - Hardware Hacking General

Hi Guys,
I own a HTC Sensation with Android 4.0 ICS installed als OTA Update.
Some months ago I got a broken Touch Screen Digitizer Glass but the LCD was still ok.
So I decided to change my TSD on my own and bought one original spare part. As I startet demounting and unglueing the original TSD I cracked some regions of the original microphone and button flexcable.
Once the TSD was changed the Sensation would not start anyhow with the broken flexcable. There was only a reaction on the lightning of the buttons but no funktion of the sensation at all.
But today I even changed the damaged flexcable and after this I tried out to start my repaired sensation. But now there seems to be a different problem. The sensation hangs up on boot procedure with its white screen showing the three characters htc in green. And after a while it gives a soft reset und starts this procedure from the beginning. I can't switch it of, the only chance was to remove the battery.
While I was testing the new TSD, there was short a normal function for one boot but after this I was not able to bring this status back once again.
If I press the Power and Volume Down Button, I get to the bootloader. So the Sensation seems to be running in some way.
What can I do? Is some of my changed hardware cracked and forces the sensation to reboot with this neverending story?
Can anybody help?
Thanx a lot,
Matthias

HELP! Touch screen no longer working!

This morning, my touch screen suddenly stopped working. Hardware keys are still working but device is not responding when the screen is touched. Already tried a hard reset but no success, now I am stuck at the align display screen. Also can no longer get to the bootmenu, so can't reflash my device! Any suggestions on what's wrong or how this can be fixed? Thanks for any help!!!!
I'm curious
Didn't you see any spots (like oil spots on the water) to the touch screen ?
I had the same problem .I replaced the touch screen and the phone is working again .
No, nothing, was working fine at night, when i woke up just randomly stopped working. The display is not cracked or anything, so wondering whether a screen replacement will do the trick? ALso strange that I can no longer get to the bootscreen to enter HardSPL...
Had the same problem, the issue (with mine anyhow) was the digitizer, which is an overlay that sits on top of the actual LCD screen to give it touch capability....
good post here

I had a similar problem,
To get past the Align screen I had to apply pressure to the top of the screen opposite side of front facing camera - then use the screen as normal
I reflashed the original rom (manually getting to bootloader) - it worked for a bit but ended up sending is back to 02 for repair.
All they did apparently, was to reflash the ROM again and its been working since.
Had the same problem a couple of times a while ago, when i was trying out WM6.5.
All buttons worked but not the touch screen. Never really found out exactly what the problem was, but the first time I managed to get it working again by resetting the alignment:
While gps button pressed (under green button), press center D-pad button this will bring you to alignment screen.
The other time the "alignment trick" didn't work, but i got it working again, after flashing the original ROM couple of times. (And doing hard reset between each time)
I think I used this ROM
You say you can't get to the boot menu, do you run hard-SPL?
most likely its an hardware issue - had this one too, of course out of nowhere!
flash with original rom and if you cannot align screen (as the hardware seems to be broken) send it in for repair. it will be under guarantee, if screen isnt broken.
I had similar problem, I passed the alignment but i had a huge offset in the touch.
I replaced the touch screen and it solved the problem.
You can find it in ebay for 1 US $.

Thanks for all the help guys!!! I do run hard-SPL and have flashed many ROMS - just don't know why it won't enter the bootscreen anymore when I reset the device and press the camera button. Did manage to upload original ROM again by using activesync, now trying to restore original hard-SPL so I can send off the device for repair.
Hi, i had also the same problem, i find a threat in the internet... try to push the upper corners on the device with your fingers and then tab on the screen to see if the problem solved.
I had the same issue.
Its more than likely your digitizer. I tried flashing 100 different roms but always stuck at the align screen stage.
I actually have the barely used digitizer if anyone wants it (for a few dollars of course hehe) My mainboard died a couple of weeks after i installed the digitizer.
needless to say i moved away from the ****ty build quality of HTC to the MUCH better build quality of the iPhone.

[Q] my touch screen not acting properly

please can anybody tel me what could be the reason tha my touch screen is not working.. i hav htc touch hd.
it sometimes works and some times doesnt.
thnx
Touch hd screen not responding to touch or stylus
Touch hd screen not responding to touch or stylus
--------------------------------------------------------------------------------
In early February I upgraded my Touch HD to 6.5 from 6.1 and if am right it was energy.blackstone.21891.leo_Max. It worked for about two week and and then one day I struggled to get a gps fix on my tomtom. The next day the screen just froze with no response of any touching or stylus.
Managed to put the original orange rom back on it but could not cariberate the screen due to its not responding. I sent the phone to HTC UK for repairs but they said due to my having used unauthorised software the motherboard needs to be replaced and they were asking me to pay 168 pounds so they could go ahead with the repairs. I got the HD2 on a new contract.
Still love the TOUCH HD and was wondering is there another way of breathing life into this thing. Responds well to install new roms but the screen continues to remain frozen
Hello.
I have same kind of Problem.
My HTC had broken Screen, I had it repaired.
After it came back the touchscreen worked OK. Than I flashed it with the ENERGY Blackstone ROM.
Flashing etc was OK. Device started again and came to the Point where you have to tip on the screen to do the SETUP. But that did not work. I tried Softreset. Hardreset but No change of Problem.
Send it back to the repairshop and after I recevied it again the Energy was still on it and working.
Since a new ENERGY rom was out, I flashed it again . Result, Same Error, NOT working. To make sure that the ENERGY-ROM wasn't the error, I reflashed it with the Original HTC ROM.
Also this one does not work. It also comes to the point where I need to tap to do the Setup. Nothing happes.
When I attach the Phone to PC with ACTIVESYNCH, the Synchronisation works OK.
Any Help Any Idea ??
Probably you need to replace digitizer(touch screen layer, not LCD) Look on ebay for a new one.

Damn, I have almost the same problem!
I have used Energy roms for a year, without any major problem. I have installed dec. 20. NRG rom, and today it is completely messed up my HD. No response on touching the screen or pressing any button. After a hard reset the touchscreen alignment was came up, and the touchscreen is working, but I can't align the screen, it starts over and over again... and thats all. I cant do anything else with it. I have reflashed stock rom and spl, still the same.

same with me here... I also have got an EnergyRom installed. For more then one day now I get no response from the touchscreen. Everything else seems to work properly, e.g. the popups which remind me appointments are there.
Exactly the same here!
I installed energy sense last week, phone worked fine for 4 days then i came to use it and it didnt respond to the touch screen, however tapping the screen would bring back on the backlight?
I hard resetted it and also flashed a new ROM on, still the same, I found that it was responding but taking up to 5 mins to respond, i.e if you tap the first calibration point, after about 3 minutes the point moves, however calibration never completes.
I think the phone is scrap.

Doesn't work touchscreen

I have Htc Hd2 phone.A few days ago unlock screen doesn't not work.I pull lock screen down but it did not respond.A few days ago sometimes it work sometimes don't work.But now it does not work at all.I can't unlock screen and when finish instal android and android requires me to I fill information and touchscreen doesn't work again.What to do ?And SIM pin can not enter.
I have install many androids and windovs mobile but it don't work.
My htc hd2 has not been dropped or anything damaged.
Sorry for bad language.
Happened to me 2 weeks ago. Touchscreen didnt work at all, across all 3 operating systems. I had no choice but to flash my phone back to factory settings in winmo. Had to remove HSPL aswell. Then off to repair for HTC
Alls good now though
there's a search button for a reason you know
plenty of people have the same problem as yours and posts about how to solve the problem are already in their respective threads.
Here's the most common cause for your problem:
the digitizer wire goes right under the power button, so if you press too hard you damage that wire bit by bit. The only solution for that is replacing the digitizer yourself, or flash back to stock ROM and send it for maintenance, and next time don't press the power button hard.

Touch screen not working

Hi!
I got a phone from a friend who told me that the touch screen didn't work. I took a quick look at it and she hasn't been flashing roms and trying to downgrade anything.
I ordered a new digitizer off from eBay and I replaced it today. Touch screen still not working (now it even says touch screen - fail when I boot it in Vol down + Power).
Any ideas?
I'm having a problem with the touchscreen.....the touchscreen is automatically responding without me even touching it....can somebody help me...!!!

Help! Cannot unlock screen, touch function not working.

Has anyone of you guys encountered the same issue with your HTC HD2? Care to share the fix you did? Would this mean bye-bye to my HD2 already?

If a clean install (task 29) doesn't help, then I guess you have no other option than sending it for reparation.
It seems like there is a limited life span on the touchscreen. Mine died in October, and I had to buy a replacement because nothing I did fixed the problem.
I had the same issue as you, but in my example touchscreen is slowly dying. For example I can't wake up the phone pressing right (red) button. So I learned that using any other button will not cause freeze of screen. I also discovered that if you gently slap your phone on hand, magically screen starts responding. Weird, but it's ‘working’ like this since 5 months so far.
I just encountered this problem with my HD2 as well. It seems that this is a fairly common issue. Apparently the digitizer for the touchscreen is located directly beneath the red power button and has a tendency to lose its connection.
For me, holding the red power button down with some force for about 5 seconds fixed the issue. Is this temporary? Perhaps, but it has worked just fine for a few days now. Try that out.
Can't Unlock the Phone..
I am having the same problem..I can't unlock the phone..No matter what android Rom I installed.I tried to removed the lock screen and the touch stopped working..But when the phone restarts and you put you pin etc,I can use the phone normally..but when it goes black and trying to turn it on again nothing works on the screen..
Though the hard buttom works..Home screen etc..but can't get the touch to work after the screen goes black!
It's not rom related
I have installed WM6.5 (Stock), Android GB, Android ICS, Android JB But the problem appears to be the same in all
when I press Red button touch doesn't work any more
I would go with digitizer theory
BUT my question is this:
is it gonna get worse? cause for now as long as i avoid Red button everything is OK :good:
and I love my HD2 but if getting worse is possible I have to get rid of it :crying:
Well i had the same problem.now my phone has been to the service centre for reparing

Funny (or sad) thing is we don't have an official service center here
so only option is to replace it or sell it as the way it is
Try this:
Lock the screen normally, screen turns off. (Power button)
To turn it on again by pressing any other screen buttons other than the power button. (DONT USE THE POWER BUTTON TO DO THIS)
I found that if I do it this way, the screen runs normal.
