i opened it and found the part which is heating up i have atached an image, where i marked the part.
Now i have a few questions:
1. What is the part that is overheating called?
Edit: I am aware that it is a part on the motherboard platine, but maybe i can find a sollution if i actually know which part of it heats up.
2. Can i fix it somehow?
3. Can i somehow rescue my data from the internal storage if i cant fix it?
Every Input is appreciated
Greetings

Help needed: All LEDs on, Display gets bright white -> Boot Loop

Hey there. I've got some problems with my Wizard ...
One of the 6 soldering points of the headphone output was broken (insulate contact). Cause I don't have warranty left I decided to solder this little contact problem on my own, because the soldering point was big enough. I'm very sure that I did not touch anything else than the tin-solder, but now my Wizard freezes sometimes with some weird behavior:
First all LEDs light up, the display lights up to completely white very slowly. After about 20 seconds the flashlight on the back lights up and flickers. At the same time noise comes out of the speakers. After that it reboots.
I cannot reproduce it. It happens when a text message comes in, sometimes it happens when i shut off the speaker through the com menu and sometimes it happens when i enable bluetooth. But not every time ...
FYI, I already did a hard reset, replaced the ROMs with others for this model (Qtek, Mr.Clean, O2 ....). I have checked everything on the PCB very pedantic but I cannot find anything ****ed up.
Somehow I don't believe that my soldering has provoked this problem, but I also don't except this.
Maybe anyone of you had something like this before and solved it? Or has anyone an idea what part could cause this malfunction? Is there some kind of "Error Logging" Tool where I can see the last action (maybe kernel command or something like the event viewer that logs "bluescreens") that is perfomed before it freezes?
Thank you in advance!

Just to check. I had this experience of soldering stuff near a IC chip that the heat actually being transferred from the wires into the chip, with high enough temperature to cause problems. So, is there any IC around the part where you solder? Also, many of the new stuff are surface mounted, and enough heat conducted on the wiring will be enough to get some of the connector loose. Just double check that.
Hey again!
I just want to thank you! You saved my Wizard
What I did was I disassembled the Wizard completely, put it together again and tried to start it up. This failed, cause the battery was completely discharged. After giving it multiple pushes with a 9V block battery the Wizard loaded up and since then i did only have a crash when disconnecting and reconnecting the cable (I think due to the low battery voltage atm).
While cable is connected, I can en-/disable flight mode, receive text messages and enable bluetooth without a crash. Seems something went wrong when I put together the Wizard before (thinking of vibration alarm, because when you receive messages it vibrates, if you turn on flight mode it vibrates ....).
Thank you! XDA-Developers is gr8!

[Q] Replaced LCD, phone won't turn on

Hi, I just replaced my broken LCD but now it won't start. I'm worried I might have damaged the battery and I have damaged the logic board. The very little black thing pointed with an arrow in the picture below is hanging by a thread.
Symptom :
When plugged in USB, the red light flash constantly
Screen does not turn on, no vibration
If I unplug the battery and plug the USB nothing happens
I'm trying to diagnose wether it's the battery or motherboard or both that are broken
Question :
Should it start with the battery unplugged (it does not)
Should it start with a broken battery plugged
Do you think the little black thing I half broke can prevent it to start
Now that the screen is not broken, can I get the rest of the phone fixed by the warranty or they will be able to tell I opened it
Thanks !
No its not ur battery. The red light issue appears with nexus 4 a lot especially when your battery drains out to 0%. Let it charge for couple hours.

I ended up transfering the internal from another nexus 4, and it did the same thing. As you said, after charging for a while it started normally.
Although I still can't tell if the first one is working, I'll have to reconnect it to a broken screen and see if it boot after charging for a while because I forogt to do a nandroid backup of this one

Galaxy S5 not powering up after the "Samsung Galaxy s5" screen appears

My perfectly working Galaxy S5 was put for charging at night and the phone wouldn't turn on in the morning. I tried restarting it and at times the "Samsung Galaxy S5 - powered by Android" flashes for a second or so and then the phone dies again.
I tried rebooting it, unplugged/replugged the battery, removed SIM and SD Card and tried to start the phone but nothing happens. On charging the phone, the screen does come up to show that the phone is being charged and as of now it is 100% but still won't power up.
I must add that the phone has had its share of falls during the 2 year usage and there is a small discoloration / crack like effect on the top left hand corner of the screen which however cannot be felt by hand by rolling my finger on the screen.
Samsung guys claim it a screen problem that needs to be replaced however an independent repairer is confident that screen is OK and it has something to do with some other hardware of the phone. He even removed the battery and connected a multi meter to the point on the phone which connects to the battery, tried starting the phone and the meter would show some current getting drawn and then come back to zero. He claims phone is not able to draw current from the battery.
Any clues what could be the problem and how to rectify it. I have loads of data I don't want to lose on the phone.

Can you boot into recovery? Have you tried flashing a new firmware on the phone?

Phone isn't responding at all. No matter what I do, at the most the Samsung screen flashes for like 30 seconds and then the phone dies again.
On connecting with a computer the computer begins to recognise the phone and starts installing drivers for the same however it never completes the job.
So not sure how to flash a new firmware if the phone isn't responding at all.
Bumping the thread.
Another reason for this behavior is that the battery has no charge. Battery can be damage and no have charge at all
I would in this order
do you have another S5 available?
exchange batteries and see behavior
do not have another S5 available?
try to charge with a universal wall charger.
or it seems you have a tester. Make sure your battery have charge
Checked battery too but that doesn't seem to have a problem. Tried with other batteries also.
A local repair shop told me there's a problem with the boot IC.
My follow up question is can I replace the mother board with another Galaxy S5 motherboard? Are all the motherboards of Galaxy S5 compatible with each other?
I'd be careful when changing the motherboard. You *DO* need to find a compatible board...In other words which ever variant you have should be the variant you look for to source the donor board.
Also, you say you have data you want to recover? Swapping out the motherboard will remove every possibility of recovering that data; as all the flash storage is contained on the motherboard.

How to locate a compatible motherboard? In other words how does one identify the variant of the phone?

All the information you need is on the sticker underneath the battery.
Sent from my SM-G900F
Interesting piece of information.
I took the phone out almost after 8-9 months today. Tried to power it on by pressing the ON/OFF button and the phone came back to life without a glitch. There was almost 52% charge, date and time were spot on. I couldn't recall the pattern, as a result I couldn't unlock the phone.
I decided to wait for a while for my partner to come back and put in the correct pattern password and left the phone unattended for a while. In between I kept checking and the phone remained ON all the time.
Unfortunately, I decided to charge the phone while my partner returned. After half an hour or so I pulled out the charging cable and checked the phone for 1 last time. Phone was still ON. I left it untouched for a few more minutes.
As soon as my partner came back I told her about the phone coming back to life. She pressed the ON/OFF button to bring up the screen and key in the pattern but the screen just didn't come up. I have tried number of times since then but nothing.
Phone is dead again atleast as of now. Thinking of keeping it back for few more months and will try again.
In the meantime any sort of help will be highly appreciated.
Please note more than the phone I am keen on the data inside it. Need to recover it.

SM-T530NU "Overheating", calibration?

Have a Sm-T530NU that has misbehaved for a long while, originally the OEM battery was thought bad. Yet after it was changed to a new off-brand battery and working on and off for a year and some, the tablet has started misbehaving again, mostly not charging and turning off alone. And recently has started showing the temperature warning icon while charging while off.
So, I've opened it again and digged down, and discovered the battery connector on the PCB wasn't well soldered, the contacts danced in the pad, so I retouched the soldering with flux and a little new solder and it seems ok (I can recheck again later if needed be), so I tested the original battery with multimeter and seemed acceptable, so I installed the original battery back. Charged it for a while, and, again, warning icon for temperature while off, and it switches back and forth between charging and warning... I turned it on, and it works, but throws an error once in a while about being too hot and closes all apps... this, I think should be something related to cpu heat and not battery one... (also wasnt charging during this). So, I read online that some of these tablets with a modem have a service menu (*#0*#) but of course this one has no dialer, so I've tried several programs to try and get into the service menu, my idea is to see if it's possible to recalibrate temperature sensors, for battery and for cpu, but I've not been able to open the service menu by any means (the last mean I have is trying an intent initiated by am but the tablet is not rooted and there's permission issue for asking an intent of uid 2 from uid 0....).
My questions are:
1) Is it possible to get to the service menu of this model somehow? with or without rooting? Is it possible to recalibrate sensors from it?
2) Should I recheck the battery connector? would a battery "overheat" (caused by a bad connector connection to the sensor cable, or a miscalibration) cause app shutdown during run? or is it related to cpu/gpu overheat? I see some phoen models (S2) can cause this message from torubles with the usb connector/pcb, this doesn't sound too logical on my case, but, is it a possible source of problems for this tablet too?
3) If it IS a cpu overheat (though tablet feels cool to the touch) is there anything can be done to help with this issue? micro disipator maybe?
Thanks for any advice. I'm willing to try odd or hard stuff to fix this.

S7Edge Dead?

HI Everyone,
My device is not turning on nor its charging. It was having appx near about 40% battery left. Suddenly it start getting laggy and freezes. Error system ui stop working came and I decided to reboot it by normal way. However the display goes off and now no LED, no charging and not even opening into download mode or recovery.
Is my phone dead?
PS. before all that happed I was just browsing internet and it wasn't over heated at all.
If I want to recover data out of it, is it possible to send it to manufacturer and recover it somehow? or alternate way?
Thank you

According to me your network ic or capacitor is shorted. you should go to samsung but they will ask you lot of money. so go to a nearby phone repair shop.
It would have been great if my phone gave me time until Note20 comes up, now I will stick with my old spare phone until then.
I was curious if it can revive, because my phone was getting 0 care from me, I had my screen wet and lost the display two time however it revive after drying it for few day. Now it had enough of me I think. RIP now.
