Hi, sorry if this is in the wrong place.
I just replaced my digitizer but now the damn phone won't switch on, I had it switched on and working perfectly after the screen refit but when I powered off to put in my sim card, it wouldn't switch back on,
When I plug my charger in the LED will not even come on.
I read that some people had the same problem with ipod screen refits, and the solution was to short the battery terminal, I really don't understand how to do that, plus it is a different thing altogether.
Has anyone had experience in this?
Thanks for reading
When I say the LED won't come on, I mean the LED that usually comes on when plugged in and charging.

Hi all, I've had my Desire since they 1st came out, so about a year and a half now.. Had the same rom on there for about 10 months..
Last night I was sat at my desk and the phone just slides out of my pocket onto the floor, no big deal and it's not a big drop at all, I pick it up and go to turn wifi off and the phone just turns itself off, I try turning it back on and it stays on the pink logo for ages.. about 5 minutes before it reaches the lock screen but I cannot go any further because the touchscreen is no longer working.
The charge light doesnt come on, the battery icon is red all the time and the big battery appears on the screen saying please plug in charger, if the charger isn't plugged in then the phone just turns itself off.. Battery is 100% full and I even charged it on my partners desire and also tried her battery but it's the same.
I can access the bootloader but I cannot select anything as when i press any button the screen just turns off, and when i press any button again it comes back on. The phone will stay running in bootloader mode from the battery for hours and hours so maybe this could help pinpoint where the issue is as when the phone is on the lock screen it claims the battery is dead when it clearly isn't.
The phone still has reception and even H is connected still but I can't do anything at all.
I'm hoping somebody will recognize these symptoms so I can perhaps buy the correct part to fix this.. I'm pretty sure the fault is not the screen.
I have the phone layed on my desk now, I've stripped everything away and just left the screen and board, attached battery.. Same issue.. Detached screen and plugged in charger with battery attached, no charging light..
Two weeks ago my galaxy just stopped working. it was at a decent battery; just stopped. I tried charging it but the phone would vibrate. phone would come on, then shut off. I tried it multiple times and same result; a few times the phone would make it to the samsung startup animation, sometimes it would just flash the samsung logo, once it compleley got to my screen start before shutting off.
I brought my phone to get fixed. It took a whole week and the guy said my phone was just not fixable. It would work for a few hours then shut off again, according to him. I suspect he didnt work much on it though as hed rather fix phones with easy problems as mine was a tough one.
I've had to replace my phone with an iphone now, but right now, out of curiosity, I completely took my phone apart, and started using tweezers to play the power on button. The camera part just broke off (not the actual camera) but now my phone is actually charging! The red light is on, and click the main button, it shows the battery being charged. This has not happened ever since the phone broke.
Am I bricked? Is there hope for this phone??? Please tell me there is lol.
EDIT: My phone seems to have restarted! Turned it on and it's asking for my simcard what is GOING ON LOL

idont know what you did there, but it worked plus you gotta be more specific to how the phone broke and could not boot-up to screen

It just randomly shut off. It was if someone would constantly be turning the phone off as soon as I turned it on. But then I couldn't even charge the phone. No red light, no screen, nothing, just vibration. I would try to turn it on sometimes it would get to the boot up, sometimes not, sometimes nothing, just a vibrate.
I literally took tweezers and lifted the green board out from around the power on button (it's an actual tiny white button on the inside). and then it randomly started working again

Could be a power button failure. Happens somewhat often.
Could be battery related too, a cheap replacement battery could strike that off.

agree with what he said, it could be a problem with the power button or battery is not working
off topic did you really get 176Mb/s download or is it fake
if its real then was it WIFI or DATA , i have never topped 50Mb/s both wifi and data) but DATA seems to be 10x faster than my wifi
I replaced my HTC One X screen because it's cracked. I am pretty sure I did everything correctly.
I followed this video:
https://www.youtube.com/watch?v=f3wxy4wUlRw&list=PLv54VHJgYuodvmY7ySEUEjOZcbptZtmG7&index=4
I tested the new screen out mid-way, like the video, and it worked fine (I'm using the SHARP variant, as it was identical to the cracked one).
I then placed the screen into the housing, and connected everything back up. Put the screws back in, but before putting the back cover on, I tried testing the screen. It wouldn't turn on. The capacitative buttons light up on reboot, but the screen does not. When plugging it in, the notification LED lights up a constant orange, and it comes up on my computer.
I've read some people having this problem, but I'm not sure what to do.
I took the screen out, and put the old one in (the cracked), and it too no longer lit up! Same problem as the new screen. So how do I fix this? The Flex cable is 100% in the jawbone connector, so it's not that. I don't think it's a short circuit, although it is a possibility.
I spent $90 on this, so it's quite disappointing if it's all gone to waste.
UPDATE:
I found out that the screen is working, it's just extremely, extremely dim. It's so dim that I needed complete darkness in my room in order to see the screen. I only glimpsed this once, and I haven't yet been able to get it to turn on again.
What's strange is that the screen doesn't even light up when powering on, there's no HTC boot animation or anything. Is this a hardware, or software issue?
I'm going to fully charge it, and take the battery out for 3-4 hours, and see if it fixes it.
I think it might be a shorted 220 coil, that's the only explanation I can think of to cause both screens to not light up.
Does anyone have any experience replacing the 220 coil? As I'm not sure how to remove the 220 coil. Do I just pry it off?
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.
Hi,
Having some issue's with my M9, I replaced the battery as the phone was unusable in that you could charge it to 100% and if turned on, if you unlock the screen it will turn off and act like no juice left in battery, put back on charge and starts at 0% charge then after a short while, jumps up etc, but of no use.
Now with the new battery, it plugs in, red light at the top to indicate charging worked, the charging icon and percentage on screen works, however the phone will not turn on, any ideas what this could be as been googling to no avail, seen different reasons for lack of power, but nothing really in regard to a result of fixing this issue I have now.
Hope someone can help.
Regards,
V4mpire
just as an update, I found out that I had broken the cable going to the power buttons, luckily I have a M9 from when I was in the US and took the sd card tray/power buttons cable and put it in my phone and it works.
