[Q] No touch screen-Black screen - Desire HD Q&A, Help & Troubleshooting

Hi there,
i'm searching for an answer from anybody who can help me.
The issue is that i just change my screen and digitizer from my hd and now everything works, but always in black screen and no responsive touch screen.
I take off the sim security for test the phone and the phone starts with the typical little vibration, after that the typical htc boot-sound and after that, i make a call to my hd and the phone rings normally, so i think that everything is right, except these to big issues...
Any idea?
Thaks XDA.
Edit:
I made a blind factory reset in Hboot mod and the same result

Sounds like you didn't put the cables back on properly. They can be really fiddly, I would recommend taking it apart again and reassembling. I have had to do that a few times on iPhones which have a similar cable issue (fiddly and pressure sensitive cables)

Thanks man,
But i release and conect them many many times....
Thank you again.

HTC Touch Diamond Screen not responding

Hi All,
My diamond screen suddenly stopped responding. The screen calibration is also not working. I tried a hard reset and after that, it stopped at the screen 'Tap the screen to setup your windows phone'. I am not even able to do that. Any help is appreciable. Thanks in advance.

Try re-flashing a rom, or maybe your touch screen (digitizer) needs replacing, if you do this yourself i would recommend buying the digitizer and lcd together as one, it will make a whole lot easier trust me lol. The lcd screen is easy to break.
Had this problem, too, but since I couldn't get back to stock SPL at that time I put my Diamond into a shelf for about 2 days.
When I then tried to get back to stock SPL the screen suddenly responded again.
So, try to take off the battery for a long time (more than a day) and hope it recovers.
Didn't have the problem again.

I had a similar problem solved with changing the touch screen since the phone was under warranty I have to revert to the stock SPL and stock ROM before I gave it for service. If your phone is not under warranty you can buy the touch screen from ebay.com with a manual and all required instruments for replacing the same.
This happened to me because I was talking to someone over an hour in a humid place which caused sweat to get into the phone through the speakers.

Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!

Putting the phone in the fridge makes screen work!
I know this is an old thread but why does putting the phone in the fridge for a few minutes make the touch screen work? Even if I put it out of a moving car and it cools down, then it works for a bit.
Anyone know why this is and how I can fix the phone permanently?

Xperia plays touchscreen

hey there guys and girls,
This is my first post and was just wondering about my xperia plays touchscreen. I bought it almost a year ago and since i got it the problem has been occuring. Its not major dont get me wrong but it can be really annoying when i am texting my frineds. What happens is that i will press a letter then it will just decide to press a bunch if other letters next to them. Also the keyboard will randomly go down so ill end up clicking send and completely wasting a text.
Any help would be great... Thanks xD
Large fingers? lets hope its not a digitizer problem but you did state its been happening since you got the phone. the xperia play does seem to me to be more sensitive to the amount of pressure needed or not needed; or is it just me?
Got used to using swype keyboard on my sgs and haven't used the stock keyboard on the play.
you could try to clear data for the keyboard Settings>Applications>Manage Applications>All>"keyboard"
maybe another keyboard will solve your problem entirely, there are plenty of them on the market/store.
this is just one as there are many
https://play.google.com/store/apps/...xLDEsImNvbS52bGx3cC5pbnB1dG1ldGhvZC5sYXRpbiJd
edit: forgot to mention, if you install this or any other input method you will first need to enable it in Settings>Language & keyboard>"keyboard"
just tick the box next to the keyboard and it will give you a prompt; read>OK
then say in messaging just press and hold on the text input field and select input method>select keyboard you want to use
also, when your keyboard disappears for whatever reason or doesn't show when needed you can press and hold the menu button for a few seconds to bring your keyboard up or make it go away.
I pulled off the screen protector and that seemed to fix it for me.
i've been having the exact same problem, it seems to occur mostly when my phone is charging or when it's too warm. Didn't bother sending it back though, but yes, it can be verry annoying when trying to text
Don't worry, its a standard Sony Ericsson issue. Usually occurs when the device overheats.
Reboot or look into ROM flashing and the problem will be resolved

Mine does that when there's moisture on the screen, or when plugged into the charger. I've found typing to be much less annoying in wet conditions when using Swype.
Dry off your screen often enough and it should help. Removing the anti-shatter film (which is next to useless anyway) also makes a difference.

Welcome to XDA!
Try solutions posted above.
If You ever need to test any piece of hardware on your phone, try accesing serice menu by typing this code in Dialler:
*#*#7378423#*#*
From there You can access Service tests menu and test Your Touch Screen/Earphone/Display just to mention a few.
Also screen protector isn't any good for me, standard keyboard is too small and stock firmware is to laggy to type messages. Solution is easy if You are ready to give your phone a boost by flashing it as mentioned by someone else above.
Wow, there is a great amount of different anwsers
I remember that someone on these forums said that Xplay has problems with multitouch regonizing (or something)
Basicly, the touch points wont reset unless you do something (i dont remember what)
Personaly, i just press powerbutto to "shut down" my screen, press main menu butto and open the lock, its all back to normal
EDIT: wait few seconds (like 5 or so) before you reopen the screen
i'm having a similiar problem, i charged my phone with 5v a couple times, so the last week, the touchscreen doesn't work. sometimes it does, it has been abit tricky. it like works sometimes, with an effort of constantly mashing the screen (with swipes and presses), but the last 24 hours, it's been practically dead. every other part of the phone works, like LED, pad controls, speaker, etc etc, just touchscreen is dead... any solution, methods?

Honestly, I have no idea. I just know that the digitizer is what makes the touch screen work, and that there have been xda users buying them for replacement parts before.

I have been getting this problem when coming in from outside. I can hold my finger about 1cm above the touchscreen and it will type random letters as well. Seems to be affected worse in bottom left hand corner for me. It settles back down after a while of being indoors. Its really weird though.

That's because the difference in temperature and humidity causes condensation to gather on the screen, temporarily. Capacitive touch screens work by conducting electricity, and moisture is conductive.

[Q] Xperia S: Phone unresponsive when connected to Charger/HDMI/Headphones

Hey guys,
I have some weird issues with my XS and I don't know whether they are caused by software or hardware. Here's what bothers me:
Every time I connect something to my XS like the usb cable to charge it or transfer files, an hdmi cable or even headphones my phone gets totally unresponsive. The touch buttons respond after about the tenth press and even the screen is unresponsive as hell. If I scroll through the app drawer for example, my swipe gestures are often recognized as a press so that apps are launched although I made a fluid swipe gesture. On the other hand pressing on a screen to launch some app sometimes isn't recognized at all. If I plug out the whatever cable, everything's okay again.
So, what do you think? Is this a hardware or a software issue and what should I do now?
Some background information: I already tried a factory reset and such things. My phone software is stock ics (see signature).
Regards

Hmm i havent experienced that before. Try updating to .50 stock and see if it is still there. If it is try and roll back to gingerbread. This will tell you for sure if it is sofware or hardware.
I'll try that but if you say that you never experienced that before, hardware would be more suspicious.

Many people experienced this, i still have it.
They said its a touchscreen fault or something and its needs to get replaced by sony.

Are you planning to send it in? I mean I hate this bug and it bothers me a lot, but giving away my lovely phone for a while seems a bit cruel
Can I send it directly to Sony or do I have to send it back to my vendor (amazon)?

Guys I have the same problem. When connected to the official charger and USB cable the problem is minimal. However with a car charger or an auc jack/headphone the touchscreen is unusable.

Re: Touch screen problem with Xperia S (LT26i) [ICS Problem?]
Hey diyotama,
The guys at Meteor Ireland that sold me the phone are sending it to Sony for repair today.
Thanks,
sobanek
PS. They've identified the problem as a battery problem (something with voltage) that's why when anything was plugged into the phone, the touch screen would lag - because it didn't have enough voltage for the touch screen, and therefore, it wouldn't recognise all my touches.
​
The problem is I've unlocked bootloader and flashed some roms, lately very satisfied with Slimbean. However there are some issues with flashing and warranties.
I wonder if sending in my phone for repairs would be wise. So I would like your advise.
Is the cause a battery related problem? Is this ROM related?
Send in the device or live with the results of flashing?
I still dislike this issue but I can live with it now.. I noticed that my touchscreen bugs mostly in the lower parts of the display. So I installed some framwork mods that allow to use my phone upside down (rotated 180° and onscreen buttons enabled). So in the end its not a big deal for me anymore because the most touches are performed in the lower section of the screen.
I also unlocked my bootloader lately. If you want to send you phone in you can relock it but maybe they find out what you've done. But in my opinion this is a clear hardware issue which hast nothing to do with unlocking or flashing. So I think they can't say that this is your fault.. Regarding the voltage theory: interesting theory but I don't think this is true.. As I said: my touchscreen works perfectly in the upper part while charging but not in the lower..
I had issues like this when I used a different charger.
Yeah thats right.. I found out that the original Sony charger delivers 1500 mA.. If my phone is connected to this charger, the effect is at least noticable.. But when I connect my phone to my 800 mA car charger, the phone feels absolutely unusable..
wut... I got tired of using a screen protector, so I took it off. Immediately I noticed the screen became unresponsive at times, and discovered it was the bottom part that was unresponsive (as @mister-g1 wrote). But it only happened when the charger or aux was connected . And then I re-applied the screen protector and the problem was completely gone! I can reproduce this in real time with the app "touch test" and record it if anyone is interested.
So it looks like I need to buy some new screen protectors..
Also, did anyone send their phone in for repair and got it fixed?
When the screen protector is altered, you must change it. Regarding that other problem, well...always use original chargers, headphones...etc. If along the way you did otherwise, well, that's the source of your problem. My advise is that from now on you must use only original chargers/headphones/etc and your phone will adapt back, it may take a while but it will do it.
TIP : Try plugging in the headphones while the screen is off. See what happens when you turn it on.
Best of luck.

I should be able to use it without screen protector.. Anyway I bought 6x screen protectors, so I have enough for a while The problem occurs with original charger and headphones, and when I plug it in when the screen is off. And even though I have used my N7 charger, that should not be a problem.
Sent from my Nexus 7
Same here.. I always used the original charger and the problem was always present.. And using another charger shouldn't be a big deal.. Thats definately a hardware issue.. Think of the yellow tint screens and so on.. Sony does not always deliver the best screens.. The Xperia SP has similar problems like shown in this video:

Exact the same thing happens if I try drawing linesa while charging..

Not so usual screen problem

Hello guys, after screwing up my phone I'm using my tablet a lot more. So i'm experiencing some problems. The screen problems increase when i use the tablet more often, but i don't have this phantom touch problems it's actually the screen stop working. It just stays on lock screen and me unable to unlock it, i restart the tablet and still doesn't work. However the strange part is that when i hit the back of the tablet in something it immediately starts to work??? I know about the N7 touch screen issues, but i thought they were software based? But mine looks like it's hardware problem? Can you explain me and help me? Thanks.
Can somebody answer me??

If it's hardware, it's most likely, though not exclusively, the cable connections. You need to take the back cover off, and reseat them one by one. Takes a little work because there are 3 cables, one with 2 prongs. Reseat all of them if you can since you don't really know which one caused the problem.
Warranty?
Ok i saw some videos that it may be replacing the screen cables just as you said, but i have warranty. What to do? If i take it to warranty center it's most likely it will work there at the moment? It stops in random times.. What to do?
Removing the back without voiding the warranty is very simple but make sure that you will wear some sort of protective gloves and not touch any copper foil at all ( or you end up with finger prints.. ). Simply reattach the touchscreen connector cable only and you´re good to go.

Thanks for the info. Actually i can fix it easly not by hitting, but just by pressing the back cover. I saw where the cables are in a video and can permanently fix it by putting something between the back and the cables to keep thwm in place. And when i press they just go in place. For now i will just press it when needed. If the problem increases i will open and reattach all cables in place. Thanks for answers.

[Q] Note 2 N7100 Screen problem, help me Samsung owners from entire world :D

Ok, let me start with this,
I bought a note 2 n7100 couple of days ago, and I have problem, i don't wanna believe that I have to change entire display, because, it's way to pricy.
My touch screen reacts perfectly with stylus, and when I try to use my fingers, NOTHING :/ It won't react, i tried everything, from factory reset, to entire ROM change, but nothing happens :/ It still doesn't work with my fingers, stylus perfect, but fingers, nothing.
Please tell me that I can fix it somehow without entire display replacement, i googled it, but blank, tried every trick that i've found and still nothing.
Greetings
PS. I just need confirmation that it is hardware problem, and that I can kill all my hopes about fixing it any software way

I doubt that it is possible, ive heard that digitizer is glued to the screen :/
Actually it is possible, search for 'LE55ONS' on youtube, he has a video that shows the complete disassembly of the Galaxy Note II's screen.
I heaved same problem, i think because condensation inside your phone.
