Xperia Z3 compact vibrates non stop!! - Xperia Z3 Compact Q&A, Help & Troubleshooting

I bought a refurbished Z3 compact (worse decision I ever made). The first time I turned on the phone, it started vibrating instantly and kept on vibrating until the battery died. I flashed marshmallow ROM hoping that it would solve the vibrating issue but no luck. If I shake the phone, the vibration stops but after a few seconds it starts vibrating again.
I replaced the Flex cable with a new one that I bought from aliexpress.com but issue still persists. While I was replacing the Flex cable, I noticed small salt deposits on the flex cable connector on the motherboard. Another thing I noticed is that if I touch the spinner part of the vibrator with my finger, it starts spinning and if I touch it slightly again, it stops vibrating.
I thinking about buying a new motherboard but before I do that I have to be absolutely 100% sure that vibration is caused by a fault in the motherboard.
Any Suggestions?

[Q] Milestone screen not responding

I have had my Milestone for a while and it is out of warranty. Recently a narrow strip on the right side (when held vertically) of the phone has stopped responding to touch. It has decommissioned the search softkey, the backspace, L and the P key of the keyboard.
However, I have noticed that the touch response on the left has increased. For instance Q, A, and Z keys respond even if i touch the black edge of the screen, this goes for the back/return softkey as well.
This leads me to conclude that somehow my phone's inner working's alignment to the screen has been disturbed.
I have tried several roms...CM7, Froyomod and stock froyo but the problem remains.
I did use a third-party car charger once that gave me the ghost screen issue. Draining the batter to 0 with the app Battery Refresh and charging it to the full with Milestone charger solved the issue.
I'm in Bangladesh and there is no moto here...there is no support and sending the phone abroad for a fix is not an option. I'll have to fix it myself or save up for a few months to buy something else...not a bootloader locked moto again.
So, any suggestions? or directions I should be going or looking at?
1. The ghost touch appeared for me, too, after flashing FroyoMOD. I left the phone for ~a night slided-out, without battery, micro SD, SIM etc ) and it worked fine for ~5 days. Then, the same right side stopped working. We don't actually know what is the problem (moisture, bad charging, wear of the flex cable, defective digitizer) and we also can't be sure if we replace the digitizer the problem won't appear again. So, I suggest that you should sell the phone.
2. You could get an i9000, an LG 2x or a Desire HD.
L.E. I'm 95% sure that this isn't a software issue, so flashing different ROMs wont help.
same issue...
solution: dumped stone, got galaxy (Y)
My milestone eventually died. No M logo even. Thinking about getting a Huawei U8500 as an interim phone before I get something good.
Try Iphone insted
Once I got the same problem, it was not on the edge, but the middle of the screen & U, J & N keys stopped working. It was under warranty so I got the things replaced.

New display assembly won't work

HI guys,
I want to post on behalf of a friend who has a problem with his Xperia Z1. He originally bought it used with a broken display, he then changed it with success, the phone was working fine until it fell. At this point the display was still working but not the touchscreen, so he ordered a new assembly from the net (not genuine, like the first one which worked tho).
Upon receiving his new assembly, he immediately started the repair. However, when he turned on the phone, he only felt the vibration and nothing appeared on screen. No any light, he got a totally black display with no sign of life, while the phone was fully charged, and was recognized by Windows (he could even access his files on the memory).
He obviously thought that the seller tricked him and that the assembly was defective but when he tried with the old one (which had the display working but not the touchscreen), the same result showed up, no light, like the assembly wasn't plugged to the motherboard at all.
So far that's what I told him, check the connections to the motherboard, and make sure the flex ribbon is not damaged. He even bought a new ribbon and installed it, with no success.
He read that the problem can come from the display ribbon touching the chassis, thus making a short-circuit, but I doubt it. How if the display connector on the motherboard is broken? Is it fixable? Like buying a brand new connector and soldering it.
Thanks in advance for helping us
Try a hard reboot by Golding vol + and power until phone vibrates. Is the backlight working?

Click to expand...
Click to collapse
Thanks for reading this long problem
Sure, he tried the hard reboot thing, he even successfully flashed a stock ROM but nothing changed. I can only think of this as a hardware problem, but what part is defective?
The motherboard connector?
The ribbons on the chassis? But he changed to new ones already!
The LCD assembly? Same, the one he tried is a new one...
Still no one to solve the mystery?
I'd like to add that the phone turns off itself after approximately 30 minutes in idle state. That is, the explorer doesn't show the phone anymore and it has to be powered on again.
I know the best solution would be to buy a new motherboard or just forget about this broken phone, but it's a challenge to fix something that is apparently hopeless

[Q] Screen Replacement Leads to Unbootable Phone

So I recently cracked the screen on my HTC One m7. I bought a replacement screen and front housing. The screen was so far beyond repair that I couldn't shut off the phone prior to starting the replacement. I tried waiting for the phone to die but after two days I became impatient and did it anyway (essentially the phone lost power when I disconnected the battery). After transferring all parts into the new housing and being what I though as diligent putting all parts and connections back in their place, tried to power the phone back on. all that happens is that the back and home buttons flash and then I hear what sounds like the audio for when the phone powers on. The screen stays black and then phone doesn't technically turn on. I know this because I have missed messages and the green led light would be flashing if it was. Therefore, at this point I'm not certain that the new screen works or if I've connected it right. I've tried the numerous boot tricks with the volume buttons, nadda. I have had the phone on a charger for a full day and the same problems. (Disclaimer: I don't have the original charger, but I have been using this one for a long time). I do see the red charging led if I wiggle the charger in the input, but also just recently I saw a green led when doing this, which when the phone was working was a sign that it was fully charged. If anyone has a solution to my problem that would be great. I'm also interested on what's wrong, why this is happening, what might have caused this behavior? What do the flashing home and back buttons mean?
Howdy,
I've had the same problem, but my phone was shutdown allready. When I replaced the front screen, the phone won't boot. I would like to know if its anyway to get the files from sdcard down?
Thanks for the support!

Xperia Z1 (C6902) issues after a few centimeters in water photography

I will explain what happened as elaborate as possible so that some of you can help me with the problem I've been facing.
I have put my phone in water about 5 - 10 cms in my aquarium for a video. 1 was 20 seconds and as it came well. I've took another video for 47 seconds. After that I've tried checking for problem in any component of phone and everything went well. I've shared videos and then used my phone as usual for a long time and phone was completely normal.
I've placed my phone on dock for charging and the magnet didn't work in the first instant. They just didn't stick. I thought it was some issue and I just rubbed my phone to the dock twice or thrice and the magnetic action came back along with a wide array of problems.
I removed from dock while charging and the screen started to randomly blink and the touch never worked. I placed it back in the dock and it charged normally. After a while I've removed it from the dock and the screen got blank all of a sudden scaring me to death. I placed it back and again took it. This time it worked completely normal as if nothing happened and I was able to send a text message. I thought that was just for one time and placed it back for charging and that was the last time my phone touch screen worked.
I removed from the dock after a while trying to unlock the screen and nothing happens. I could use all the hard buttons on the screen. I was able to capture photos using the camera button. Change volume, lock and unlock screen. I tried switching off using the method of volume up + power button. It turned off and on turning on it got even bad. The sony logo blinks a lot it goes dim it comes bright and all sorts of weird things happened. I've removed the sim card and turned on the phone to charge and now the phone restarts after every few minutes.
Even now except the touch screen everything else works fine like the camera. I tried removing the screen protector but that didn't help.
Hoping to have an answer other than taking it to a service center.
Thanks
It seems that not all of z1s are waterproof. I had mine in the sea in about 1 meter deep for 30mins and its still completely functional ( I wash it every day too). Anyway, sorry to tell you but simply there isn't any way to fix it yourself. The only thing you can do is take it to service. And more bad news to come: your warranty doesn't cover damage from water, so you will have to pay. The only thing you can try is blowing your phone with a hairdryer for a few secs, but thats risky.
Took it to the service center. Asked them to check the flaps before they accepted the mobile and there was no water through flaps as the flap litmus is completely unaffected. They took it under warranty and the next day called me to say that it had water in the display connector and the same warranty void answer but I've requested to let me know how the water went inside and they said it was through the bottom speaker grill which clearly means manufacturing defect. Along with escalating the issue I've also asked for a quote for the repair if the warranty gets void and today they came up with this wonderful quote of ₹20,179 its wonderful because I purchased the phone for ₹17,600 just a month ago. The request for manufacturing defect inspection is under progress so I wish to get some good news.
More strange things here. I have completely lost all of my speaker grill but my phone is still 100% waterproof. It's clearly a manufacturing defect, but I doubt they will accept it . Sony support and service is just terrible

Sony Xperia Z3 E6553 still no display after LCD replacement

Good Day to All,
I have a problem with my Z3+ E6553, the problem is that there is no display on the phone. Couple of weeks ago the lcd just stopped working, the device does come on with the LED lights, vibration and the touch is reponsive with which you can here the touch sounds, haptic feedback and the Speech to text speaking. I thought the LCD screen went dead and so I bought a new LCD screen to replace it but after replacing the screen the problem still presist with no display(black screen). So currently I have no idea what is the cause or what to do next.
I opended the phone was just check some things out, and I had a look at the LCD flex cable and I found something strange that maybe one of the connector antenna prongs missing. But I'm not sure if thats just how it is or its maybe it got damaged. Have a look at the attached pictures below.
Can someone tell me if this issue is with the LCD motherboard flex cable, or another hardware issue maybe being the motherbaord?
