Touchscreen not working on a area - Xperia Z5 Q&A, Help & Troubleshooting

Hi there,
After some water leakage, I've got the phone dried, but still with some marks of water in the display, most common in the back.
I've opened the phone, removed the battery, tried to dry it even further, but without luck.
The problem is that the screen is no longer working in the row of 1,2,3 numbers or the first line of dots, so I cannot introduce the pattern to unlock the device. Is there anything I can do?

Align screen, endless loop

Hi all,
Yesterday evening the screen on my TP was misaligned all of a sudden. This has happened before, I don't know why but I know how to fix it or so I thought.
Open the start menu and find the screen alignment tool in the system settings did the trick until now.
I can align the screen all I want but it just keeps asking me to align. I've tried soft reset, hard reset, leaving the battery out for a night and aligning over 50 times but it keeps me in the alignment screen.
What happened? The screen obviously functions as it detects the taps.

BTW. I run RomeOS 1.40.1 (Dutch) en flashed the stock rom to test if that fixes the issue but that has the same problem.
Align screen loops again when you don't tap properly on the cross. Obviously you're taping properly but maybe the screen could not percieve it properly. Did you ever drop your baby?

Uhm, I never dropped any of my babies but my TP has dropped once or twice but that is weeks ago and the fall wasn't that great, the hit wasn't that hard and it functioned normal after the drop which was in the grass btw.
I'm sorry to hear your troubling situation. I had a similar situation happen once with my hermes, turns out that the outer rim of the housing was coming in contact with the screen and registering as a contact. I was in the endless alignment until I opened up my phone and closed it again. I had other reasons to open like the speaker cable had also came disconnected. Try running something thin and lint free around the edges of where the housing and screen meet. If that doesnt work I would just return it while its still under warranty.

[Q] White Scree with lines?!! Hardware or LCD?

Okay so yesterday I came back upstairs from doing some stuff downstairs. i pulled my phone out of my pocket and bam, there's a white screen with colored lines all over my screen vertically. Almost like if you would take the screen and stretch it as much as you could. You can t see anything. So i decide to see if the touchscreen still works and well, it does! I can even receive phone calls.
The phone is rooted, and has a cracked but functional digitizer, no water damage nothing. I have tried turning it off and on, and well in order to take the battery out i would need to open it, which i only want to do if i need to replace the LCD.
So my question is, Is it the LCD that needs to be replaced, or could it be the hardware. Any fixes guys?

(The screen has previous cracks, but this problem occurred way after those were made)

HELP!

I think that the LCD Panel is damaged, it is not the hardware since your touch screen is working and colours can be visible on the screen. So just change the LCD Panel:thumbup:

Touch Screen work after water submersion

Hello, ladies and gentlemen (and those inbetween, too)!
I will try to keep this as short as possible. If you want less details, tl;dr section at the end. EDIT: i.... didn't quite think this through
My girlfriend has an Xperia Z3 which she bought from a random seller from Germany (am UK residents). Everything about the phone was great, it was brand-new albeit it has been, apparently, been the display device; but other than that it worked perfectly. We even tested out the waterproofness right after setting up the device and charging it up to see if it works. Back then, it did.
Now, this friday (frikkin' Friday the 13th) she had some sort of an art project going on, which she wanted to do underwater. She does have a GoPro for it, but for some sample shots before finishing out, she decided she could just as well use her Xperia. Now, I was sleeping at the moment so I did not get to witness how she did it, but she assures me she closed the flaps extra carefully. However, after she tried submersing it into water, the screen started blinking randomly, as if there is some problem with LCD matrix of some sorts.
We put the Xperia into a bowl of rice and left it that way overnight. After turning the phone back on, the screen showed first "Sony Xperia" logo, then completely went blank. Just a random look-around on the Internet showed me that for extra help it would be best if you take your water-exposed phone and leave it upside-down while it is drying out. I was hopeless, but I didn't want to disappoint her so I said it would work. I was sure it would work since at times, when turning the phone on, some images did work out (like the charging icon when it's turned off and charging) so most probably the phone is not damaged yet, its just still exposed to water.
Next day, after leaving it just standing there upside down, the screen worked as normal, and normal touch functionality returned as well. Not for long however.
My final hurdle is this: When you turn on the phone (after being in vertical upside-down position) and hold it properly (as in, again, vertically, but upright-down) , the touch functions work very well. For a couple of minutes. After that the touch functionality artifacts (faulty touch detection, ultrahigh sensitivity etc) return. It appears that the water is still there somewhere, and as you hold the phone correctly, it goes down back a bit and impairs functionality.
Now, the question is: What can I do to completely remove the water from the device, seeing as keeping it in rice for 2 days did not remove the impairments from internal water exposure entirely?
So far I've tried only rice. Was bad call, but I did not think of anything better and used a bit of hairdryer at the very beginning of the issue, and yes, I now know that it was a stupid idea.
I think I will leave it in one-two more days upside-down in rice and see how it goes from there. Before turning on, I also thought about using the vacuum cleaner method of attempting to suck the water out of it through available holes.
Any other suggestions, tips and ideas? Would seriously want for things to go back to normal, considering now I do not have a phone (gave mine to girlfriend in place of her ill Xperia).
Thanks for your attention and I hope your devices stay healthy and safe!
tl;dr exposed Xperia Z3 to water with problems, turns out the damage was reversible and everything works well so far but touch functionality is faulty, still water stuck inside the phone that impairs touch screen, tried drying it by leaving in rice, gonna leave in rice for a day or two more and use vacuum cleaner on the holes right after, anything else that I could do?

Problem with Display-exchange

Hello,
First of all i dont know if this is the right forum for my question. If not so please notice me.
After my Z5 dropped on the floor i got an broken Display. I bought a new Display and changed it, but i think i broke the LCD-Flexcable after i pulled carefully on it to get it inside the case. The effect is after phone turn on i get only the backlight but the screen remains black. So for a test i switched my old broken display in it but the effect is the same, only backlight and black screen. After a few seconds the phone led blinks 3 times red and the phone restarts. What the heck is now? Anybody get the same case? I handled the mainboard with care, dont remember to damaged the connector in anyway. Does the Flexcable needs to be protected with a tape so it couldnt be grounded on someway?
Sorry for my bad english. Thanks for any help!
After a second and a third display swap the error is still the same. It seems somehow i damaged the motherboard. I swapped the phone against a new one.
Please help, same problem ...
