Hello together,
I have a Z5 (6653) that didn't start anymore and got extremely hot while charging. To be more clear: after connecting the phone to the charger the red LED turned on, then after about 10 seconds later it turned off again. From this moment on the phone's back started to get extremely hot. The source of the heat is about 1cm right and 1 cm down to the back camera (so you can say 1cm diagonal from the camera to the phone middle). Because of this I doubt it has to do with the battery as it should heat the lower two-third and not the upper third of the phone. Maybe the processor is at this place?
I tried to connect the phone in flash mode with the PC and it connected, but disconnected after a few seconds, probably because battery was empty. I repeated this procedure (connecting to charger, disconnecting, reconnecting, connecting to PC) a few days and suddenly the red LED kept on and the phone didn't get hot anymore.
So I charged the phone fully and wanted to start it, but the screen won't turn on anymore. Connecting it to the PC and the Phone drive (MTP) is displayed but empty, because you need to unlock screen. Also I hear the connecting sound of the phone and touch feedback sounds.
I tried the following things:
Xperia Companion Repair
Flashtool flashing newest ROM
Flashtool downgrading to 32.0.A.6.152_R5B (LP ROM)
Nothing helped. Well, the idea it is an hardware issue might be at hand, but maybe there is something else I can try first?
And if it is an Hardware issue, what is the cause? The Display itself? Then why was a single point at the phone back the source of heat and not a large area on the phone front?
A short summary:
Phone gets hot while connected to charger
Battery won't charge (LED indicator turns off after few seconds)
Source of heat is 1cm to the right and down to the back camera; after 2 minutes whole phone is hot and you can't recognize the source
After days of repeating the action (connect to charger, disconnect, connect to PC, connect to charger) it suddenly charged the battery and didn't get hot anymore
Display won't start anymore; still responsive
Tried Xperia Companion Software repair
flashed latest Stock ROM
flashed Lollipop Stock ROM
Phone has locked bootloader and is/was not rooted. I'm grateful for all help!
I guess its a dead screen maybe u droped it and the pins of the screens got ejected from the motherboard.. Ignoring the fact that it was empty of charge and you charged it.
From what i understand that the phone is working but there is no screen.
The best thing u can do is to check a hardware store that is capable of diagnosing the issue.
Im not helping here i know but wanted to share my thoughts..
Gd luck with that.
Thanks for this anyway. But phone didn't drop.
The fact that the phone wasn't charging and got hot instead at the beginning is very irritating. Especially that it wasn't the front but a point at the back near the camera. Is there a way to check if it's a Display issue and not a Mainboard/Processor/other Chip issue?
At least in Germany are a lot of stores that aren't too competent at all. But nobody would tell you, so its very helpful to know as much as possible before going to a store.
I think it might have something to do with the gpu inside the soc? The heat might have burned something inside the mainboard (how hot was it btw, like running intensive apps or even hotter than that?) Another thing that might have happened is the display cable is loose.
I've seen some Z5's screens and they're not that easy to die.
The best thing I can suggest is that you repair it in a trusted shop that lets you observe the repair procedure directly (open the phone, take the parts out, identify the problem).
Good luck with your phone.

I never played any game so it is hard to compare, but I never had a phone in my hands that got this hot before. You didn't get instantly burned touching the phone but it was already inconvenient hot for your fingers/hand.
There might be some trust able stores to find, but I doubt somebody will let you observe it, not even Apple store does. If you see the trick of how to repair it easy and fast, you might do it yourself next time. And it is also a question of the price. If I can buy a used but totally unharmed Z5 for the same price, why should I let it repair?
As far as I could see in Germany repairing Display starts at 99€ for the Z5. Buying display with adhesive would start at 49€. But if they change the Display and it's still broken you have to pay for the Display and also for the mainboard i.e.

Hi all.
Lately I'm facing a strange problem with my device.
when I navigate with it in a sunny day,
or talking on the phone while charging,
the devices gets hot and the screen goes down.
I can hear that the device is working and the buttons is working, but the
touchscreen is 'dead'. its all black.
Even a softreset won't fix it, the device goes up without the screen.
To fix it I need to pull out the battery for like 2 minutes untill the device gets cold.
is it hardware problem? Anyone else experienced any of these problems?
Thanks!
...ehem...
try to charge it via USB and not a car charger. Is there any difference now?
IMHO you should replace the device
the same problem
Hi
I have the same problem than you
I can use my Polaris in my computer with MyMobiler application but the sceen it's always black.
Sometimes when I do a Hard reset and press button left side it's OK but after some days it's comming again.
I think is not a hardware probleme but software problem.
Do you have resolve your probleme ?

I haven't resolve the problem yet.
the screen getting black is due to the nature of how a display works. i dont know of it actually damages the device, but i strongly believe so.
the working conditions of the device are written down in the manual, if you exceed those they might not replace your unit. this of course sucks, but it *is* written down to not expose the unit to direct sunlight.

I didn't know about the exposing to the sun ...
well, I hope it isn't got damaged badly.
thanks.
As I said, I'm not sure about the damage part, I could be completely wrong. I just think it *could* be...
If it doesnt change and the device gets unusuable all the time, I'd suggest you send it in for a replacement. Maybe you really got a bad unit, who knows.
Edit: I just thought of stuff which is usually written down in manuals and the glovebox problem popped in my mind: devices stored in the glovebox of your car are breaking down because of the sheer heat which builds up when the car is standing in the sun for a long time. All sorts of displays usually break or get completely black until the unit could cool down again... And in the glovebox they werent even exposed to direct sunlight, its just the heat...
hello. I have same problem. But i can't catch situation when it appears. I think, the sun is not an main culprit, because my phone goes down, when i
playing games in the room! may be it's overheating, but cooling doesn't help me.
To fix it, i do several soft resets (sometimes more then 300 ). Sometimes one reset helps, sometimes no. I think, it is hardware problem. Also i have problems with my camera (colormess). May be they are connected.
I will try to send it to service.
Hey, i put my device into refrigerator, and screen is working . I have tried to reanimate it since yesterday. Battery unplugging didn't help.
F*******K!!!
After ten minutes in the room with temperature near 20 C it's black again.
Can be problem with temperature sensor?

Don't put it in the refrigerator without putting it in a plastic bag or something. Moisture can kill it.
i put it into plastic pack.
But i think, that I'll kill it myself by throwing in the wall
Hm, question:
Where does temperature sensor dislocated? In battery or in PDA?
Well,
In the lab they told me my Board damaged up.
total-lost
What kind of damage?
this problem i faced it two times ,one of them when i put it inside my car and the AC was runing (cold) and my screen became black
and the other time it happened in a hot condition (also in my car)
realy this is very strange
and the solution for both to remove the battery for a while
Hi all
I have had my nexus 5 for a while now and just as i was flying overseas some strange things happened.
First the vibration stopped working which i knew was a loose connection on the back of the phone. Holding that area down would get it working again. Then the touch display stopped working. The LCD worked but could not touch anything to unlock the phone. I disassembled the phone and assembled it again and strangely it worked again although i didnt see anything obvious. Then is happened again...
I disassembled the phone and played around with it for a while and noticed if pressed down on the connection where the flex cable connects to the motherboard it would work again. but when i would release the pressure it would be funny again. I did this a number of times until eventually the whole LCD/blacklight should shut off. Now i can rarely get it to display anything. The phone is working because the LED light would flash and i can hear the messaged coming through. I just cannot see anything.
I replaced the flex cable with a new one and still the same issue. I replaced the LCD + digitizer + frame and still the same issue. I guess its the motherboard. Can i fix this ??
Now for some more issues:
I bought a broken Nexus 5 while overseas and i swapped the motherboard out and everything works! So it as definitely the motherboard. However, the second motherboard is having issued the the battery. I have every indication the battery is charging. However the battery percentages is stuck on 40%. It would flicker around 39% 40% instantly and when looking at the battery graph on the phone it is noisy, it is not a constant line. The percentage is not a true indication of the battery charge. I cannot get the phone to turn on just by the battery itself no matter how long i charge it for. I have swapped batteries out and i still get the same issue. I have swapped flex cables and still the same issue. Could it be that the second motherboard is also damaged??
I used the amphere app for a while while i had some power and it shows 100mA while charging but a voltage of 0V! When I unplug the cable it will shutoff. Sometimes i cannot even boot it up while charging.
Amphere showing 1%
h**ps://drive.google.com/open?id=0B9KF5ld-Rlu_VWY2eHA5VXE4R3M
What is wrong with these two motherboards?! I do not see anything obvious on the board itself.
I now see the new Nexus 5X is out but i am hesitant in buying it...This is the first phone i have had major issues with.
PS, i gave the latest updated
Thanks for your help guys. I will provide whatever information i can.
It sounds like your 1st phone is having the same problem I have with mine, which is described here: http://forum.xda-developers.com/google-nexus-5/help/main-board-socket-flex-cable-super-t3217281
Use a magnifying glass to see if any pins on the socket are broken. I still don't know if it's fixable.

So i've been having a lot of issues with my N5 lately, mostly small stuff like general slowness, poor battery life, not surprising on an almost 3 year old phone. I also lose cell service way too frequently (not an issue with my carryer, all my friends are on the same network and are fine). Camera won't focus anymore (though im pretty sure this was my fault, probably broke it while taking it apart). I'm pretty sure the battery connector on my motherboard is damaged. I've had many problems with the battery reading its temperature as -30 C (battery heath "cold"), i've replaced the battery 4 times now and i still get that problem every now and then. Pushing on the connector fixes it temporarily, so im pretty sure some pin is bent slightly out of place and i don't know how to fix that. It recently started having this issue where just moving or bumping the phone the wrong way would cause the phone to shut off. Probably an issue with the battery connector again. I tried fiddling with it but it didn't do much.
The other day i turned it on and the LCD was backlit, but black except for one single vertical white line. Rebooted and it looked normal. Few hours later i got really pissed off with it for shutting off in the middle of an important text and threw it at the wall (not the best idea i know). Screen was already cracked so i didn't really care. Ever since then the LCD has been a real pain in the ass. i can turn the phone on but there's nothing on the screen. Ii get haptic feedback when the Google logo would up, and the notification LED is flashing like i have a message. The backlight is on and pushing hard on the cable connecting the motherboard to the daughter board i can see it start to turn on, (Google logo, few seconds of boot animation) but then back to black (while still backlit).
I can post photos if it would help diagnose/fix this, my phone is my main camera and i don't want to bother anyone if i don't have to.
Anyone know any tricks that might squeeze another mouth out of this dying phone? Any response is appreciated, Thanks!
The issues could have been related to the power button or physical internal damage. My suggestion: replace the screen with a cheap 3rd party screen if the internal components are still working. This will give you more time with your existing phone and allow you to have a working backup.
As you can see in thread, phone just dead. Dunno what happened. I bought it an year ago. I've tried to connect it to computer and it was visible as QHSUSB bulk but now i can't see it there. It doesn't react for turning on. I can't get into download mode, recovery mode. Very long time ago i flashed Android MM from xda and it was working good. It had ~50% of battery when died. I've tried to put off battery and then connect to pc but still nothing happen. It has broken screen (was working good) but i've done it in September 2016 so. I can connect it to Linux but i think it won't help too. Any fixes? I think they won't take It at warranty because of screen. Phone looks like dead for ages :<. @edit IT'S NOT DEAD! I've disconnected something from battery this longer one and when i click power i can hear "something" in the phone. And it gets heater so looks like processor is working. But it's still not visible in the device manager.
edit2
i know emmc pinouts.
While I was using the phone, with battery at 66%, the exact same thing happened to mine. I'm sick of it. Time for a new phone.
(Had the rooted V15c image on it, no broken screen, only the camera issue - should someone care)
Same problem here, what is happening . My phone was approximately 80-90% and it suddenly turned off and I can't turn it on ..
bump
Phone went black with warning
The same just happened to mine. It was fully charged and I was using it and then the screen went black. There are no lights when I plug it in, no vibration after pressing and holding the power button. Nothing
I've connected it to my pc and a driver installed, I think the same one as a post above (QHSUSB) but still the phone doesn't respond in any way.
It's the European H955 on official MM 6.0.1 no root or mods and is out of the one year warranty yet was in excellent condition. Does this mean the phone is for scrap and nothing can be done?
Hi, I found a solution to repair the phone in this state. I start by telling you a story, a long time ago I had an HP laptop. video card was detachment from motherboard, and to a stick again we used a method called reflowing. I thought that the phone has the same problem, however we have nothing to lose so I opened the phone I took out the motherboard and started to warm up each chip using a hot air blower. I mounted the phone back and now works like new. I apologize for my bad English I am from Romania.

Any one tried this method and succeeded may please inform on this forum
My phone crashed, would reload to lock screen then restart and finally would not start at all. Before this the rear camera stopped working.
I had reset, flashed a new Rom and replaced the Camera which didn't solve the issue.
After the phone died I tried reflowing though I had no heat gun so I just used the oven. 200c for 7 minutes after disassembly.
That was about 8 hours ago and I am typing on my phone.the Camera is also working.
I will post if it stops again. I did it as the phone was dead and I had nothing to lose.
I have the same problem, and I am interested in getting a heat gun for this purpose. What specific parts of the phone did you reflow/heat? (in terms of the chips, or the entire board.)
Thanks in advance.

I did not heat the whole motherboard, just the chips under the shields.

What part of the phone did you reheat exactly? The whole phone? or did you take all the plastic out?

Also be sure to take off the rubber part on the back. The purpose is to remelt the solder.l, so only board and nothing else.
To disassemble there are some videos on YouTube. Remove your sim card before taking off the backing
Remember this is a last resort, you could end up with a completely dead chip.

Thanks for the information. Is there a specific way you have to remove the shields, or do I use a soldering iron to get it off? (And if so, does it do any good to solder them back on?)

Did it 395 degrees Fahrenheit (201.66 Celsius) for 7 minutes, I preheated the oven. The camera and everything now works fine.

You shouldn't have to use a soldering iron to take anything off. At least not as far as I am aware of.
I should note that as of this morning my phone when blank and will no longer turn on. I will try reflowing at a higher temperature as some solder may need a higher heat but I am not optimistic that this is a permanent fix.
Hey everyone !
First try to connect it in emergency mode to the computer in order to flash with LG UP. If you cannot boot into emergency mode but the device appers on your computer ( and PC is unable to connext into GF2) maybe you could burn your motherboard.
I burn one 7 months ago with my device resting on my pocket so its a common problem for this device (as official support told me so its full covered by guarantee )
Hope you can solve soon !!!
Hi, my situation is; got a galaxy s7, the rear camera was bad, bought a new original one, stripped the phone down, fitted the camera, followed the tutorial (ifixit), put a new battery in at the same time, now rebuilt it all, (without the rear case on so can still easily take it apart again) and it wont turn on, wont go into safe mode, recovery mode, soft reset etc, tried every method, also via usb to my laptop, however it does charge, it comes up on the screen with the green battery icon and the LED light illuminates as if it is charging. Therefore, the screen is not damaged. And as far as i can see, all the connections are back joined onto the motherboard, it just wont boot up.
Also, if this makes any difference, I am running the Superman rom.
Any help would be massively appreciated as I have scowered so many websites searching for someone with a similar issue with a solution and I'm struggling, massively!
Are you sure you have connected the battery as required and no other circuit was touched?
Also, do you have the certainty this "new" battery works? I suggest you do the next 2 things:
1. Take this battery out and connect your old one. this way you can check if the new battery is faulty.
2. If doesn't work, even after inserting again the old battery, take your phone to a local repair center. (probably you messed something up).

I'd start by reversing everything you did until it powers on again, if it still doesn't power on with the old camera module & old battery in then start looking at other things, i'd probably start with the battery though as it is a power issue
The new battery charges and it comes up on my screen showing the green battery image charging so it is being recognised. Tried the old battery and its the same situation. I genuinely believe I didnt accidently short anything and im confident everythinf is where it needs to be. Ive just booked in to go to the samsung shop this weekend so hopefully they manage to find skmething althpugh probably end up costing a daft amount. Thanks for the replies so far

New camera module? Did you remove it to see if it is causing the problem?
I know there are different sensors, and if the wrong one is replaced the camera won't work, not heard about it stopping the phone booting but you never know
Just taken it to the local phone repair shop, lets hope they can find something with it. Keep you updated. Thanks so far.
