Overheating causes screen problems?

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

[Q] Screen white, colors inverted after disassembling phone

Hello!
I opened my phone and removed the screen so I could replace the loudspeaker.
After I put the phone back togheter, the screen was like in the photo.
It is really weird.
The more time I wait to turn the screen back on, the more the colors start to look normal, but as soon as I turn the screen on, it starts to get brighter and brighter untill it is almost completely white.
I tried using the revert colors setting, didn't work.
Any thoughts?
Is it the screen or maybe the motherboard cable?
Here is a video of what is happening:

The screen is not the original, but it was working fine before I opened the phone a second time.
Thank you.

It has something about magnet on loudspeaker..
Magnet is too strong and it drains your color of screen.
I had this problem on my Pc when I puted my new subwoofer next to my monitor, and color run out, when I moved speaker it's normal.
Try to take that speaker out and test then.

I tried that, it didn't work.
Maybe it really was the loudspeaker but the damage was permanent...
After reading your reply I did notice that the magnet on the replacement speaker was stronger than the original one (some metal things stuck to it).
I had to replace the speaker because after I replaced the screen, the sound was really low and had bad quality, I think the loudspeaker got damaged in the same fall that cracked my screen.

Had a similar problem when I gave my shattered LG G2 for screen replacement at Gopher Mods, the guy who was manager cum only worker, did not know what he was doing and had to replace my screen thrice for similar problems. The ribbon cable connecting the LCD to the main board can be very sensitive. On my third replacement after a full refund I simply popped the LCD out a little and it solved my problem. So either the LCD connector is loose, too tight or its damaged......

Battery Problem, possible motherboard damage ?

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.

thanks for that. I believe this is the same problem also.
Although i cannot find any abnormal pins...

Dropped my P900! Blackout!

I just dropped my P900 and it went completely dark. :crying: There's no mark, not a crack, nothing, but the display is completely dark. The touch buttons on each side of the home button lights up, but the display does not.
Any advice? Or it is Samsung support next?

May the ribbon for the display is disconnected from the circuit board.

Yeah, maybe I should open it myself and have a look. Are there any warranty seals that I will break if I pry it open? I have all the tools necessary, but are there any guides for opening the P900? I wouldn't want to break anything...

This is a video on replacing the battery but it helped me when I re-soldered the battery connection on mine.
https://www.youtube.com/watch?v=VeSG0hHpAG8
I've opened mine a few times and haven't noticed any specific seals but mine was refurbished to start with.
Also I have the proper tools but found a guitar pick was easier to use personally on this tablet.
Starting at the power port to remove the back made it a lot easier for me, its pretty hard to get anything between the back cover and the tablet in other areas.

This was indeed the problem! The connector has some kind of snap lock that had come loose. So easily fixed. Thanks for encouraging me to try to fix it myself. :good:

Glad I helped!

Sorry to hijack your thread but figured my problem might be related.
About 2 weeks ago I charged my tablet and stored it away. The other day I tried to use it and it wouldn't turn on. I tried to charge it but that didn't work either as there isn't even charging activity on the screen. I ordered a replacement battery thinking it might be that, but I was wrong. I still can't make it turn on. Any ideas what it can be? Thanks

I had a similar experience. 3 weeks ago the 1x my SM P-900 is out of its protective case, it falls 2.5 ft off a table. Hits the floor. No visible cracks or breaks. I could hear hear it operating but the screen was black. Took 3 weeks to talk myself up to it but I pried off the back & used a magnifier glass to c.a.r.e.f.u.l.l.y check every ribbon connect. 1 connector's pins were very slightly off alignment. Couldnt find anything else. Put it back together...Yes! Screen works. All seems good. Took the back off again & securely taped over every ribbon connect I could find. Long time intermittent screen flicker issue (when battery was below 40%) also seems to be gone. That has been the best, eye squintin', back hunchin', shallow breathin', micro-screw wrangling, time investment my non-hardware tech self has ever spent. Wooo!

Bootloop Solution ------ > #Android #iOS #generally #Display-unit #falldamage

Hello XDA-Forum
I dont know where to post the thread, because it belongs to every smartphone brand. If you have an other opinion to that, feel free moving or deleting it.
But now..introducing myself,, a crazy dude and android noob², who tried to fix his bootloop issue since yesterday 3 p.m./15:00 Uhr and 10 minutes ago, before started writing that post, I found my solution.
Smartphone: Huawei P8, GRA09
What causes the bootloop? The fault display
What causes the defect? It felt from my hand on an oven door corner and ended on the ground.
What happened while and after its flight?
1st was turned off instantly,
couldn't turn on by pressing the power-button
after connecting to charging cable -> bootloop syndrome
if I disconnected the battery and re-connected it, sometimes an empty battery-icon had been shown on the display in loop
it seemed the p8 couldn't detect the battery, because without charging cable the Huawei didnt work
How do you know thats the display? I remembered storing an other vodafone-branded p8 with cracked functional display, in a box - and I replaced it at last.
Other defects on the display? Nope, the display is optical ok, no freezes, no graphic fails, no crack.
I was also able to enter the fastboot&rescue-mode,
adb didnt work.
fastboot commands also (command is not allowed , because p8 is locked)
Sincerely

ooh, k, thats weird.
i replaced the vodafone branded mainboard with the one from the p8, where I thought the display caused the bootloop of os and battery icon.
and it worked.
but now.... i have the issue also with the display of the other smartphone.
so it is not the display alone.
but what kind of hardware issue could caused by a fall damage, when the display doesnt have optical defects,
and the charging does not work now..
now, i have the same issues like yesterday. thats weird. :/
doey anyone have some advice?
could a flash fix the issue? or is it something with transistors on the mainboard?.. thats weird.. :/

ok, in the moment I lay it down on the ground the handy turns off instantly.

and now i have the same issues with the other one^^ wtf².
i hope it is the battery. but i dont know.... thats so unreal..^^

ok, it seems it was the battery.
and the fall damage relates the battery and the mainboard.
Because I purchased a new battery on Ebay and the vodafone-branded mainboard detects the new battery.
the main mainboard without not (but heres also a difference to the old behavior after connected to the charging-cable (the accu-sign still blinks after connecting it to the charging cable, but the boot won't work. I tried it the huawei sign will be displayed. and then it turns off and the accu sign will be displayed again)
