[Q]Phone not turning on causes? - Galaxy Note II Q&A, Help & Troubleshooting

Hey XDA-Devs,
I broke the LCD of my Note 2 while trying to change a cracked glass, brought it into a repair shop to let the phone be repaired.
Before I brought the phone into the shop I charged it and turned it on all the buttons had light and even an alarm clock I set woke me up from my sleep.
After getting the phone back from the shop the phone stopped working at all it doesn't turn on and the LED doesn't turn on while loading, so I brought the phone back to the shop and he told me that I fried the circuit board while using the heating pistol trying to repair the LCD and that the phone will only turn on without the screws as the MoBo can vent.
He unscrewed the phone took it out and put it to charge the battery showed up indicated that it's charging.
I take the phone back home and it stopped working again even without the screws.
Did the guy bull**** me, is there a way to make this work or is the phone just ****ed.
Your help and opinions would be appriciated

Xperia play overheating

i rehoused me xperia play and when i tryed to turn it on i just got the blinking red light, so i bought a new battery that worked for 45 mins when it overheated to 47degress then died so i bought a external battery charger and the battery charges but when i put it in it overheats and dies in an hour and when it charges it gets even hotter and dies faster..... does anyone know how to fix this cause i cant afford to buy a new phone anytime soon
Are you using stock firmware or a custom one?
Stock
well the same thing happened to me..
i rehoused my mobile. but when i was closing up the phone, without putting in the back housing, i tried to switch on the phone so i would check if everything was fine or not. But what i did wrong here was that i just inserted the battery in wrong direction. Negative to the positive and vice versa. Nothing happened at that time, and the phone did not turn on. Upon realizing my mistake, i tried to power on my mobile again with the correct battery connections but this time the phone just wont turn on. There was a weird red light that started blinking and the phone just wont turn on.
so i completed the housing process thinking that maybe that was the problem and there was some sort of a sensor or something but that damn thing just wouldnt turn on. even if i put the mobile on charge it wouldnt turn on. so what i did was, i again opened up the back of my phone, deliberately put the battery in wrong position, tried to switch the phone on, and then i put the battery back again in the right direction and as i press the power button, walla, the phone is alive again.
BUT...
its getting HOT. damn HOT. after only being on for about 5 min, the battery got hot to 54C. upon inspection. i found out that the battery is not getting hot, but its the motherboard that is heating up.
i went to the service center, which opened up the board and found an IC that was damaged (caused by my battery mistake).
Found the IC from china. Ordered it, and TODAY it arrived. I will be going back to the service center, for replacement of the IC. If all is OK, i will let you know.
meanwhile, check out the pic of the IC that got damaged on my mobile during the process of rehousing and my stupidity.
hey thanks that helps cause i think i did the same thing with the battery...do u have a link to buy the new Ic?
FOUND a friend in china, and bought the IC from him ..
STATUS :
just now, after connecting the new IC, the phone has started working again. its NOT heating up. Everything is working fine..
EXCEPT
that now my phone shows no signals. In the settings when i search for other networks, i find many other networks also (MEANING THE TRANSMITTER IS WORKING FINE) but the phone just wont connect to my network and wont give me any signals.
I only get "EMERGENCY CALLS ONLY" status.
I am actually getting fed up of this set. Anyways, i hope u get the IC, and your phone works fine. ( I HOPE )

I did the exact same thing and have the same problem, but the difference is when i try the reverse method it still doesnt come on but cud i get a link to where u found the IC
The problem here is the same IC from the picture. Even though I found the replacement IC from China, I still couldn't get my set to start up normally without overheating. If you remove the IC from the board, the phone will start (even without the IC) but you will get no signals
For me, I was unable to get the phone back to its working condition. So I sold the phone as it was.

By inserting the battery in reversed position you probably caused some sort of short-circuit. You probably didn't burn only IC, but many different parts. When the part is damaged and short-circuit exist in it it heats up very very quickly as the current on this part (any many other parts that are connected with it) is very big (this also causes very quick battery drainage). So it means you had probably burnt the mainboard even if the phone switches on, so getting new mainboard is the only sollution to get the phone fully working (as I think you aren't proffessional who can diagnose and repair it. Neither do I ).
I hope this helped somehow.

Hello all I too have an xperia r800i play with the same problem or better the battery under the battery becomes very hot in a few minutes, and drain the battery quickly. Moreover, even when you plug in the charger not charging? only shows the loading icon but then not charged and only the LED flashing red?
And you can not start the phone FASTBOOT? because the LED flashes blue and then turns on a second phone in the normal
how can I do to fix?
thanks
Hey,
i have the same problem.
i tried isolating a pin from battery (the midle one) and i got it to work without heating, i thought it was fixed but then i took the battery back out and overheated again maybe theres something wrong with the pins any alternatives?
i did the same thing my phone is in the fridge now i boosted the battery by usb with bare wires got it started up hoping to get to 50% charge then try a reflash see if that works

Please help me with my X-Play r800i prob.

Hello you there. I have a problem with my beloved xperia play and i think this will be one of the best places where i may get any advice with my problem. It all started when my Play fell of my hand and the digitizer glass has broken. Although it the glass was broken the digitizer was working just fine. It is obvious that broken glass is nothing esthetically nice so i decided to buy new digi. and replace it. And so i did it. Unfortunatelly something went wrong. Play was booting, vibrating, and recieving the calls BUT there was no visual. The lcd was not working. I was 'playing' with the phone for two days trying to guess what the heck is wrong. I even managed to update the software (baseband etc) with pc companion thinking the problem lied in software. Nothing more false. The software was ok. I decided to go with my phone to the nearest phone service so they can check what has gone wrong. They told me that there was a tiny (possible to see only though microscope) scratch on the flex cable from the lcd and that it has to be replaced (whole lcd). I was really despareted because i needed the phone a lot. It serves me more like a tiny pc rather than ordinary phone. I found a small shop/phone repair center where they had this lcd. Without any hasitation i've bought and replaced it. But my xperia didnt turn on! Moreover it didnt even turn on when i pluged it to the charger. Neither of my three computers found it properly after connecting via usb cable. It just prompting the message 'unknown device'. Instead the red light was constantly flashing (not 3 times in a row, but all the time). As i browse the internet i found that it may be battery issue. And so i wend to buy third part - a new battery. After insterting the phone has booted and it was working. I thought that it is all ok but no. The battery was draining realy fast. I mean realy by from 100 to almost 0 in about 6/8 hrs - of cource with wifi turned off, as well as gps, 3g etc. Well the other option was that the battery has to be calibrated properly. Unfortunately one night i fell asleep and didnt plug in the phone to the charger. When i woke up it was turned off. I couldnt turn it on again. The battery was drained 'below' zero so even with pluged it into charger it didnt boot. The red light was blinking the same as with previous battery. Neither taking the battery off or charging it for 5 hrs and more helped. yesterday i took it again to the phone service center. Today thay said that it is a problem with motherboard and it has to be replaced eventhough the phone boots up when the battery is charged with external charger. It still drains the battery a lot and didnt stop draining till battery level reach zero, the phone turn off and it could not be awaken without external interfere. I thought that it could be because of the update. I've found many posts on the internet about some faulty working sony devices after updating. But the guys from the phone repair told me that this is not a problem and the only problem is the motherboard. I mean - c'mon -replacing lcd, replacing digitizer, replacing battery and now i have to replace my r800i motherboard. I hardly believe that i am such a bad luck. Maybe you can give me some hints what to do with it. I really dont see me going to the other phone repair center and paying for another part. It is to much for me. Is it possible that it is only the usb /entrance/ fault, or is it the software problem. Please help me!!!!

[Q] Nokia lumia 900 damaged by water

My nokia was damaged by water. now as I plug it it just blinks ones vibrates, and it repeats all the time in period of couple seconds. As I think battery is dead, I removed and connected 3.7v to the pins on motherboard, phone is doing somthing like booting or smht. but screen is not working as it is damaged by water too.
So what can you recomend me what to do, how do you think phone is booting or not. do I have to spent money changing the screen? or maybe someone have used working screen and battery to sell?
Hi there,
it is always the wrong way to switch on your phone, after it fell into water...
Because if there got water inside, you'll destroy your phone by switching it on, as you are causing "short circuits" on the motherboard.
The only thing you can do now , is selling i would say.
If you have a water damage on your phone, do NOT switch it on! It's best to totally disassemble your phone, and remove the battery!!
The you should dry all parts of the phone (might take a couple of days)...

Sea water in my Lg G3

Hi everyone, I need your help.
Sea water entered in my Lg G3 while it was in my pocket and a big sea wave hit me while walking on the sea side. When I opened it I found some salt on the motherboard. The device went dead when I install the battery I see the Lg logo for 1 second and disappears. After that the notification led goes green and blue spontanuously. I took it to a repair shop he told me motherboard is gone and they don't have it.
Now my issue is if it's really gone why I can see Lg logo when I install the battery even for 1 second? In addition if this is true , from where I can get a motherboard? because the cost in the dealer is around
U$ 200.
Please help me
I had same problem with my old phone.
I suppose that you made it completely dry before you tried to turn it on.
Leave phone for few hours or try to use something to be sure its completely dry.
After that try to change battery. If something die, i think that battery will be the first. Try to use other battery and try to turn it on while is on charger.
When this happen to me, battery just gone crazy. After few circles of charging, its back to normal.
Maybe there is some residue of sea water (salt) on the PCB.
You could try to flush and clean the device with destilled water, then letting it dry completely with back cover off. It may take days for all the water rests to disappear.
If you are lucky it could still be alive....
Forgot to say that I tried another battery and still same result 1 second of logo lg then it turns off. Also this happened 45 days back and when I opened it myself I found sea salt on the board.

need help with charging problem

Hi,
Even after I fell into some water with my phone in my pocket (dumb, I know), after a day of drying out, the phone came back to life and seems to work fine - except.... it won't charge when the phone is turned on. If I leave the phone off, it charges. Turn it on (recovery mode or regular mode), and it won't charge. Anyone have any ideas if this is fixable? Should I replace the small PC board with the USB port on it? Or replace the phone?
Thanks!
I think the phone will not be replaced as it is water damaged
