Nexus 5x won't turn on after replacing screen. - Nexus 5X Q&A, Help & Troubleshooting

My screen was cracked and the touch was affected so I bought a new screen online and followed a simple video to replace it. Everything went fine but once I removed the battery I noticed a bet of a puncture on one of the sides with no smell so I thought it is external and won't affect the phone. When I put the phone together it did not start. I tried charging it which gave the red blinking led, should mean drained battery, left if there for a while still won't turn on and it was over heated so I removed the charger until it cooled down then tried again with the same observation. I did that a few times and then, the phone does not even show the red blinking led nor heat up.
Does this mean the battery is totally ruined or there could be another problem? and how can I test what is wrong?

Symptoms sound similar to the LG Nexus 4. Try reseating the battery connection

Thanks for the replay.
I have done that already and made sure the it is fine. Do you know how can I test if it is the battery ?

Help please - XDA IIs keeps turning off

I've had my XDA a couple of years.
It keeps turning off, although all the power-saving is turned off.
It turns off within a few seconds, and comes right back when you press the power button.
It does this when plugged to mains adapter, and when just on battery.
Shows battery 0%main, 100%backup.
Power light (orange or green, top right) do not come on.
Charger tests good and I bought a new battery and both it and the old battery show 3.6volts on a multimeter.
Tried soft and hard reset, but no luck.
Really really grateful for any help ...
or is to repairable? worth repairing? who could do it.
Many thanks.
Did you check the connectors for the battery on the phone? They may be dirty.

Yes and cleaned them with contact cleaner and they seem fine.
What foxes me is the main battery shows zero and the backup 100%. It's as though the XDA is telling itself to shut down because the main battery is at zero, except it isn't...
I said that you got a new battery. Did you get the same problem with the old battery?
In the worst case something died inside your BA...
Yes I got a new battery because I thought it was the battery. Both show 3.6v and both make the "aux" position in the stand glow green, but no green (or orange or red) glow on the xda itself.
So it's the XDA but is this a software problem or hardware, and is can anyone suggest how/where to get it fixed?
Thanks again!

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

Phone shut off, won't turn back on no matter what, blank display/GreenBlue LEDs HELP

Hello all. I recently made this thread where I described the phone, the LG G3 d851 t-mobile variant. randomly rebooting and not turning on without pulling the battery. (http://forum.xda-developers.com/lg-g3/help/d851-randomly-shuts-off-wont-power-t3424458). I deduced it to the replacement battery (supposedly genuine) that I purchased from a seller on ebay. I put my old battery in and everything is fine again, and the seller shipped me another replacement battery (big mistake, i know).
I put in the replacement battery, and a day later the phone shuts down again in the same manner as stated in the previous thread. I pull out the battery and put it back in and.. nothing happens on screen. The LEDS just flash green and blue. I tried plugging it into a charger, just a red LED, no display. If I plug in the phone to a charger without the battery inserted, the backlight activates but nothing whatsoever appears on the screen. I cannot get into the recovery either.
If I let the phone sit for a while, and try to power it on, I see the LG boot screen appear for about 5 seconds. Then the image flickers and fades away to black, and the LED just flashes blue/green.
Am I screwed or is there any way to salvage this phone? I'm desperate for any assistance and I'm totally open to any component level repair you guys recommend (I'm pretty broke :/)
Thanks all!
Current behavior:
Attempt to turn phone on: Blank display, no backlight, blue/green LEDs
Plug phone in with battery in: Blank display, no backlight, red LED
Plug phone without battery in: Blank display, backlight active, red LED
Do any of the above after leaving phone off for a while with battery unplugged: display begins to display the expected image for 5 seconds, then the screen flickers and the image fades until the screen turns black.
I tried the old (working) battery, and no luck either.
[edit] Hopefully solved. please read my latest post for my idiotic but somehow functional solution

It would help if you would say what variant you have (at&t, verizon, sprint). Can you boot into TWRP? If your able to get into bootloader kdz or tot back to stock.

Sorry! I am using the d851 T-mobile model. I can't boot into recovery or anything. the LED just flashes some color but nothing appears on the screen.
Behavior:
Attempt to turn phone on: Blank display, no backlight, blue/green LEDs
Plug phone in with battery in: Blank display, no backlight, red LED
Plug phone without battery in: Blank display, backlight active, red LED
Do any of the above after leaving phone off for a while with battery unplugged: display begins to display the expected image for 5 seconds, then the screen flickers and the image fades until the screen turns black.
Will update the OP
Thank you for the reply.

Possibly bricked plug it into your computer and see what it comes up as.
So strangely enough, I tried heating my phone using the most idiotic method possible by letting it heat in my blanket (I don't have immediate access to a heat gun). The screen began displaying some funky artifacts when attempting to boot with the LG logo but would otherwise revert to the behavior described in the OP (only LED working, no LCD display.).
I let the phone cool for a few hours and I'm actually able to get as far as the dialog box where it asks you whether or not you really want to format, in other words the factory data reset dialog box (when holding vol down + power to get into the recovery) with minimal to no hardware artififacts., and only when I confirm that I do does it crap out and revert to the previously described behavior. But it actually lets me use the vol keys to select an option, so I'm getting a lot further than before.
So this absolutely seems to be a hardware problem. Anywhere you guys suggest I examine before I take a heat gun to the motherboard? Any specific component I should look at?
Thank you guys so much
Take it to certified technician he will fix ur device these phones are dirt cheap nowadays so u will not be charged heavily no more than 50$ worthl
So,
after reading into this more and suspecting loose solder joints (see the various threads about screen flickering problem), I decided to pursue this route and continue trying to heat the logic board.
I'm completely broke and don't have access to a heat gun, and with no other working phone I decided to take some desperate measures. For those of you having a similar problem and reading this, PLEASE DON'T ATTEMPT WHAT I'M ABOUT TO DESCRIBE. THIS IS A HORRIBLE IDEA.
I turned on the phone to get the blue/green LEDs , plugged it into the wall, and wrapped the phone with blankets. I let the phone cook itself for 2 hours.
Yes, just like the infamous xbox 360 "towel trick".
When I went to remove the phone from my makeshift blanket oven, the phone was brutally hot and felt like a stovetop (was painful to touch for the first 30 seconds). The screen was filled with artifacts due to the intense heat.
I carefully removed the battery, let the heat dissipate slowly for a couple minutes, let the phone cool on an AC unit for a another few minutes and turned the phone on.
It worked. Phone boots and haven't had a single problem for over a day.
I guess the problem was cold solder joints after all, and the intense heat was enough to reflow the solder and form a stable enough connection to allow the display to function again.
Even ran a stress test program for an hour with no issues.
Hoping this fix lasts (knock on wood), will report back if I have any issues.
Again, anyone having a similar problem, please don't emulate me. I shouldn't even have to say why this is a bad idea. Get a heat gun, remove the motherboard and heat it that way.
I'm sure applying the proper repair procedure described in this thread http://forum.xda-developers.com/lg-g3/help/screen-flickering-fix-successful-t3397411 would have fixed my problem as well.
So, why did this problem happen in the first place? I'm guessing it has to do with the overheating issues this model of phone has (at least my particular unit). I've been playing a lot of pokemon go, so the phone is running a lot hotter than it used to. The constant high temps (reading upwards of 75c frequently from my cpu) were enough to weaken the solder joints. I also recall dropping the phone a couple times while playing the game, and I guess this was enough to knock the joints out of wack.
I'm currently capping the CPU at 1500mhz and the GPU at 300mhz and the phone is running a lot cooler now. I'm probably going to set the resolution to 1080p, cap the framerate and possibly undervolt, though this might not be necessary.
Thanks for reading and hope this helps someone in the future.

Phone won't turn on nor charge

Hello guys,
My phone suddenly turned off and can't turn on since, the led doesn't show that it's charging either, tried entering into boot menu, with volume and power buttons but nothing happens. The only thing that happens is when I plug the charger into phone without battery, the screen becomes blue...

Sounds like you need a new battery. I just changed my battery last week. If your battery is more than a year old, you definitely need a new battery.

Tried that, nothing happens, tried to connect the phone without battery to my laptop, the screen went blue, the laptop made the sound like it connected but nothing is showing neither on laptop nor on phone, screen still is blue.
If i try to press volume down and power while screen is blue, it shuts off then again goes blue...

warranty still covers? if not...id go with a new phone
Out of warranty for quite some time, found a motherboard from a phone with broken display for like ~50$ as i think it's the mobo. I can't afford right now another phone, so my best shot is this one if it's indeed the motherboard
Hey same thing just happened to me did you fix the problem yet? if so how?
Looks to me like a blue screen of death, in that case need to replace the motherboard

So I lost everything on my phone? Picture and stuff?

Tablet is dead. Disassemled it and the battery is ok. What could have gone wrong?

HI! Mi mums old tablet finally kicked the bucket and I've already ordered a new one (Mi Pad 4), but I opened it to see if the tablet would boot without battery and it didn't and actually the battery is perfectly fine giving a value of 4,2V, so it's fully charged with a nominal value.
The symptoms before death were:
- Seemingly random shutdowns, once happened to me while I was trying to install an app from the store.
- When the tablet automatically shuts down, pluging it to the charger blinked the LG logo for a second or two.
- After a while, a charging screen appears with the battery at 0% and after a while it starts to rapidly increase that percentage, like it suddenly realised that the battery already had a charge.
Now, though, it doesn't react to anything at all. The CPU heat shield gets mildly warm when the battery is unplugged.
Should I give up or do you know how could I revive it? It would make for a nice secondary tablet for the kitchen or the bathroom. :laugh:
Thanks!

I have the exact same issue. Haven't opened it yet though. Let's hope someone knows what is going on.
From the moment I plug in the charger, it keeps showing the lg logo for a few seconds, turning off, lg logo again, repeat...

Yup! That sound about the same. But I don't have much hopes left for little gpad-chan.
F.
I fixed mine! So, I convinced myself opening it up was the only solution. Then I noticed that 2 connectors were disconnected, one completely and the other was just barely touching the contacts. The other thing I did was changing the usb charging cable, but I don't know if that did anything.
My suggestion is to check all connectors. Good luck!
