I have this Xperia M, used it for about a year and I love it a lot. I bricked it somehow, wonder what is damaged.
Few weeks back it fell on the floor from about 15 inches. I saw some gray lines on display and than it istantly went off. I coulndt figure out if I bricked it for good or if its just screen, especially because LED acted wierd, it was blue even if I pulled the battery out.
Today I grabbed my loved Nicki, connected it to a charger, turned it on. No wierd behavior. Heard the vibration, than LED turned yellow - it was charging. I pressed volume rockers and I heard volume setting beeps! Now the LED is green, so I guess everything works well, only the screen is black dead, and oc no backlight at all.
I used CM12 on it and I assume flashing any custom rom or stock ftf wont work. Am I right? Is graphics chip dead?
Thnx for your help
If it was going haywire before, it's probably your motherboard, the best thing you can do is send it to service.

The notification LED (Red when charging, red blinking on notification, blue when fully charging) is always ON in RED. Regardless if the phone is on or off. It will obviously turn off if I pull the battery, however as soon as a put the battery back in, it turns on and stays on. Doesnt effect anything on the phone that I can notice, but its just always on.
Any ideas?
Possible water damage. Are you using a rom other than Stock? When did this problem start? Try and think back to when the problem started.you may have an App causing you Led to stay lit.

I bought it used. So water damage is a possibility, although the stickers that turn pink when they get wet are still white and the phone is like brand new, not a scratch on it.
Its running the Sony XPLOD rom from the ROM section here. It was doing it back when it was stock though. I assumed it was a possible rom issue, so I rooted/CWM'd/installed a diff rom.
Same deal tho, RED light is still on. Turns purple when fully charged tho! (Blue comes on while red is already on)
I know you said it was "stock" when purchased but did you do a full wipe prior to or after flashing your current ROM? Worth a shot if not.

Sounds like it could be water damage to me. You can buy new stickers, so those don't mean anything. I think there are also stickers inside the unit.
Sounds like the red light is stuck in an ON position. If this happens with all roms, its a hardware issue.
Does it come on as soon as you power on the device? If not, than I would think software.
I'd use one click Odin return to compete stock ek02 flash, run it for awhile and see if the problem happens again.
I say hardware problem same thing happens to mine aswell. I cant code but if we can get someone to develop a script or something that can disable the light that would be great because im sure it causes battery drain
Hey there guys,
I was repairing an HTC One X for someone i know, (she dropped it and broke her glass) but since i got it (ofc) i tried to turn it on.
No succes. So hey, why not walk to the charger and plug it in? No charging light.
Opened up the phone and checked all the connectors. they were fine.
During an hour or two charging, i was googling, and some people reported that holding vol +&- and power button would revive it. no success.
I'm not replacing her glass untill i know this isnt a hardware problem
Please, share your knowledge

UPDATE: Suddenly the hox's led started to blink, idk anymore what i tried and buttons and power combinations but lets leave it going. fingers crossed then.
UPDATE: No boot after the blinks (just faded away again), put another battery in it and boom, it booted. only nothing on-screen lol, lets replace that screen.
I dropped my HOX and I got another HOX with working mainboard. I replaced it and everything worked except for very faint backlight and flickering. So I disassembled the phone and put it back together again. Now I can't start the phone anymore and the solid red led burns when connected to the charger....after I connect it it flickers one time, very fast. Does anyone have an idea what it could be? So pissed of right now...
Hi, if you don't have any power at all eg no vibration or lights on three bottons at the bottom, it could be that the power connecter is not properly plugged in. follow cabble down from power button, plug is hard to get at unless you unstick power button from cassie.
If you have some power check lcd is working by using a bright light near the screen and closely checking to see if you can see anything, could be backlight not working.
just my 2cents
feel bad for ya!

Okay, I have experienced the same thing and I'll tell you what I did to fix it. I dropped my HOX after owning for only a few days and the screen was cracked. I ordered a replacement LCD/ screen digitizer part and took it apart. One of the things that I found was that there was adhesive everywhere, including adhesive on the connection to the battery.
After it was taken apart, I attempted to test the new screen. It was then the LED turned solid red and the phone would not power on (even after 10 minutes of charging). What I did was remove the adhesive from he battery connector and disconnected the battery completely. I plugged it back in 10 seconds later and it turned back to flashing green (which is normal because I had several missed texts).
So my solution was just to unplug the battery and it worked just fine. The hardest part about this whole process was putting the cover back on, especially on the side with volume buttons! Hope that helps.
I have exactly the same problem. The difference is that now that I took it off charge, the red light is flickering on and off. I cannot get the display to show! Please please help.
Hi folks,
My Z1 Compact has died a few days ago, and I was running Resurrection Remix (CM mod) ROM.
I was playing some music and I put it back on the charger dock with the screen facing backwards, and there was a little chirp coming through the speakers after which the phone was dead.
I figure I must have bricked it by turning it around, I had no idea it could damage the phone.
When connected to the charger it just gave a blinking red light. No sign of life otherwise. Cannot be turned on regardless of key combinations, and does not respond to hard reset button next to the sim card slot.
It's still under warranty so I sent it back for a repair, but the repair center refused it because it has a custom ROM.
Is there any way I can flash the stock ROM when the phone is like this? They're obviously able to reach some part of it because they see the software versions. (they sent me a screenshot)
I had a similar brick two days ago.
Z1c was playing music and suddenly became death. No response to anything, even charging led. I press power + volume up and force reset was done, with blinking led and three vibrations.
But didn't boot.
PC didn't recognize it. Nothing.
Yesterday I connect to wall charger while pressing volume up and it displayed charging status (from 75%) and the It booted.
Now my battery has this status.
Edit: can't upload screenshot. By the way battery staysed at 50% for hours then dropped.

Well I think I bricked mine when I put it the wrong way on the charger dock. I was afraid it would have burnt the circuit board, but since the repair centre can see the phone details over USB I guess it must be ok, so my next guess is that the battery is dead.
They're sending it back to me today and I have nothing to lose by trying different things.
The phone doesn't vibrate though, when connected to the charger the light blinks red. It doesn't react to any button being pressed.

You probably have the battery drop problem that is discussed on the help section...
If you mean this thread here:
http://forum.xda-developers.com/son...ttery-reporting-phone-dying-suddenly-t3095120
Then it's definitely not the same issue.
I cannot switch my phone on, I cannot reset it, and I cannot charge it.
To be honest I'm more interested in getting the custom ROM off it so that I can send it back for repair, if it had stock ROM they would have replaced whatever died.
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.
