Touch screen replacement problem - Xperia SP Q&A, Help & Troubleshooting

Hi all Members
I need a little help. I've replaced touch screen on my xperia SP. Everything seems to be ok, until I lock the screen. Then when I want to unlock the phone by press side power button, sometimes is touch screen not responding and looking dead, but sometimes not a everything working. During freeze is impossible to unlock phone using touch streen, it is not responding to any fingertip. Side buttons like volume up and down, power and camera button working normal.
Then I must to remove back cover a manually touch off button by pen. After power on phone everything work for few minutes, hours ...
The touch touch screen ''freeze'' after power button press repeat daily about 5-10 times.
The freeze is ONLY when unlocking phone.
May it be by use touch screen from ebay? (maybe not original, I donť know) ... this model http://www.ebay.com/itm/291440460418?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT
I'm using Panadroid 4.4.4 ROM and before touch screen replace I have not any problems.
Please, help me :crying:

nobody to help me ?

Are you trying to reinstall a rom?
Because this touch screen is remanufactured and have chance the hardware is not same. And your rom is configured for previous touch screen. Take a chance

Htc Tytn 2 Screen problem

Hi everyone,
I got a HTC Tytn 2 and i have a problem with it.
When i boot the phone it starts up and goes into windows like every windows mobile phone.
But when i press the standby button my screen wont go out of standby.
Only when i reset the phone it will work again.
Anyone got idea's ?
Oke, since no one responded.
Is there any way how i can make the Power Button replaced with the Speed Dial Button.
Because i think my power button is broke.

Have you at least tried backing up your data and doing a hard reset first ?
Yes, and i have also tried to put on a new rom and even updated the radio.
Iam a little bit out of idea's...
here are some more ideas:
1. how to test the power button: you say pressing the power button does not wake up the device once it goes to sleep. conversely, does pressing the power button put the device to sleep while the screen is on? if the power button is unable to make the device go off->on as well as on->off, then the power button is likely broken. if pressing the button achieves on->off, then the power button is probably ok and some software issue becomes more likely.
2. how to enable wake on pressing ANY hardware button: look for an option in Settings. i can't tell you the exact option because the ROM i am using does not have a link for this option, but this option does exist 100% in stock ROM and in lots of other ROMs. it contains settings like "Lock all buttons except power button" and "Keep all buttons unlocked" or something similar. by using the second option, pressing ANY hardware button while the screen is off will wake up the device.
3. you can use AE button plus to perform even more advanced button (re)mappings.
4. just to be sure that your device is really working correct, does the screen wake up when you call the phone or when you receive a text message? if it does not wake up even then, then search for "sleep of death".
Thanks for the response.
I think its a Service of Death problem.
Because when i try calling/smsing it, it wont go on
The buttons do work then...hopefully there's a fix for this problem...
Oke, i tried switching to 2G or 3G only but that didn't fix my Standby of Death.
I also bought a new sim card of vodafone so i wont get a No Sim error.
But what can i do now about it...it hangs like every 5 min...
Okay, after a will testing, the phone hangs every time its almost like when iam on the road with my tytn 2 and placing it upside down, it hangs.
But when iam putting it in the leather holder it doesn't hang.
Any had the same problems ?

Black screen with backlight

HI every body, I have a problem and I'm asking for help
a while back my HTC HD7 felt in the sea. I managed to get it dried and fixed and it worked fine
but every now and then the screen goes black. normally i fix the problem by taking the battery out
the problem happened again a few days ago, and the screen won't turn on, when I turn the phone on I see the backlights turning on and the touch work fine and I can hear the keys and the unlock screen sound, but can't see anything
I tried to do a hard reset but the volume up key is not working so I can't access the hard reset menu.
my question .. is the a software to do a hard reset via PC. or can I use the headphone volume keys instead of the device ones???
I'm running WP 7.8 official, and a window 7 on PC.
please any help is appreciated ...
thanks

[Q] Z1 power button problem

Hi
Iv had my Xperia x1 about a year now. The phone works fine. The only issues I've had are that the speaker grill on the bottom and the silver ring around the power button fell off. However these were not major problems for me as I don't use the waterproof features of the phone so I've left them as is.
However today my power button has been playing up. If I touch the button, without pressing it, the button acts as if it's been pressed and locks the phone. If I keep my finger on it the phone turns on. The button works fine while pressing it too and the phone is working perfectly fine aswell. It's just this touchscreen button issue. Iv Googled it and most power button problems for the z1 seem to be related to it not working etc however mine works fine.. It works too well actually.
I was thinking maybe the part is loose and needs replacing.
Would replacing the power button fix this and does anybody have any idea what's going on /what I should do?
Thanks

Nexus 6 Screen Response Issue

Whenever I disconnect/reject a call on my Nexus 6 the phone screen doesn't respond!
I can lock the phone and use the screen swipe up to unlock it, but after unlocking it screen doesn't respond.
If I hold the power button and touch on power off or power on, it works, the phone powers off/restarts!
When unlocked, the nav buttons work. But the part above the nav bar buttons doesn't work. It however, works for the above mentioned cases
It's very irritating yet funny how it isn't responding.
Is the system frozen?
No, lock and unlock works, on screen nav buttons work, restart and power off menu works!
Is the touch screen not responding?
Nope! Consider the same answer as above
Can anyone help me with this issue please?
PS: Only started facing the issue after updating to Android 7.1.1 (Yes, I did manual OTA install)

Power button doesnt wake up the phone.

Hi,
My note 8's screen got damaged a month ago, but
from past two days the power button seems to be
unresponsive.
I have to press it atleast 10-15 times for my screen
to wake up.
Even if the screen doesnt turn on by a single click,
the usual touchscreen functions still work.
Ex: I can still open the particular app by clicking the screen
on the specific area.
Kindly help.

There's nothing any of us can do to help you when it's a hardware issue like this. You need to open the back of the phone using a heat gun to loosen the glue and then take the power button out and replace it with a new one.. There's nothing else that can be done and I would suggest that you not shut the phone down or let the battery die out because then you may not be able to turn it back on until you get the power button taken care of!

Hi MrMike2182,
Thanks but let me elaborate the issue.
The power button seems to be working fine because it takes approximately 10 to 15 clicks to turn on the screen (sometimes 1 or 2 click)
Let's say that I click the power button and the screen doesn't turn on, the screen functions work fine despite showing black screen.
Ex:
1. If I click on screen location where samsung music is placed and open it, and if I and click on the location of the play button, it plays the music just fine.
2. If I click on the restart button when the screen is black (not turned on), the phone does restart. The Samsung logo lits up just fine. (Mensing to say, the bootup process is not affected)
Also, note that if I successfully manage to turn on the screen after clicking the power button 10-15 times and if I put it to sleep again. I can easily turn on if I click the power button immediately (within the span of 2 seconds).
The problem persists only if the phone is kept I'd for 5 to 10 minutes.

Ok based on what you said now I don't believe there's anything wrong with your power button and when you press it and the screen doesn't turn on, in reality it actually is on and it's possibly damaged which is why you can still use the screen functions with the black screen. Whatever type of damage you say happened to it could be causing the backlight to not work but the screens touch function is fine.. Try rebooting into recovery mode and select to clear the phone's cache only and see if it helped anything.. If it doesn't help anything it's pretty much a screen hardware problem and you'll still have to get into the phone's internals..

Thanks,
Unfortunately, even factory resetting the phone didn't work out.
Anyway, I will take for service.
Hopefully it might resolve the issue

Since the factory reset didn't work, then unfortunately it really is a hardware issue.. I think you need a new screen..
I have the official led cover case, just opening the case will turn the screen on... Just a temp fix until you can get it repaired maybe.
