G4 Screen very slow to wake / Water Damage - G4 Q&A, Help & Troubleshooting

Hi,
For background...
I have the H815 and had no issues. Until I had the misfortune of it falling out my back pocket into the toilet after doing my business
In a flash I had it out, powered off, battery out, etc. Then being a little too hopeful that water didn't get in too far I tested it, it still worked, but I could see water behind the screen, so I removed the battery and let it dry overnight. Next morning it wouldn't turn on.
The good news is after pulling it apart, cleaning it with Isopropyl alcohol it's up and going.
My issue is...
It now generally takes 5-10 seconds for the screen to light up, regardless of if it's via the power button or knock knock (which now misses 70% of the time, you can tell when it works cause the LED flashes blue, then 8 seconds later the screen wakes up).
Once the screen is on, it often refuses to register any touches, so I can't put in my swipe pattern.
If I'm lucky enough to get through the unlock screen everything works 100%. No issues with the touch screen. No lag whatsoever. Knock off works seamlessly. Everything is fine.
I've tried a factory reset, and changed between having a pattern unlock, to just swipe, to no lock screen.. etc. Nothing seems to have an effect. With the no lock screen option I've had it wake up using knock knock, and then not register any touches.
Should I be pulling it apart again and trying an extra soak of the motherboard in the Isopropyl while the screen sits in rice?
Seems strange that everything works so well, just the wake-up process being the problem.

Screen dead from minor water damage. Help?!

Short story...this weekend I had my Gnex about 2 feet from a hot tub and was periodically changing songs on it, getting drops of water on the screen and sometimes wiping it off with a towel. Fast forward to an hour after leaving the hot tub (with a fully functioning phone) and my battery dies during a phone call. I plug in the phone (powered off) and a few hours later turn it on to see the screen black/white fuzzy like a tv without reception. I restart but see the same. I pull the battery and shove it in rice for a day... the phone vibrates upon powering up but now nothing at all shows on the screen. I dismantled the phone today and saw the water sensor attached near the charging port is pink. Any thoughts on how I can salvage the phone? My computer recognizes the Gnex but the folder appears completely blank. This phone has been through much worse, I can't believe small droplets on the screen did this. Thanks in advance for any advice.

[Q] Phone will not stay booted in OS

Ok, So here's the story. My Fiancee and I had our phones get water damage. Both were soaked on a wet table that had drinks being served on it. My phone was mostly protected as it had a good otterbox on it. hers only had a small silicone case. Mine is ok after a night drying out though on closer inspection of the inside, I'm glad I let it dry for the night. Hers on the other hand wouldn't boot up. I let it dry for another 24-48 hours. Took it apart and there was some major water damage to the board. Ok, no prob. Alcohol swabs to the inside and cleaned all up. Boots up but no screen. Take it apart and clean again. Swap my phone's board with her's and the screen will turn on with my board in there. Ok so its not the screen. Cleaned her board again, and removed the sim and microsd plate, cleaned behind there. But I noticed there were a few, I'm not sure what they are (mabye resistors) they were burn out/crumbled on cleaning. F' me, Right? Anyways, re assemble. Power on, YAY the screen works. Boots up to main screen AWESOME! play with it a min, POWER OFF. WTF!?! Ok no prob just a dead battery. Swap with my phones battery. Powers up... On main Screen BAM, POWER OFF, EFFF. Ok plug it in. Boots up, powers off till I'm Sure battery is dead. Plug it in to a 1A. nothing 2.1A Powers on but dosen't stay on. once off it will not go to Battery Screen. Just power up and then off. I don't mind wiping if it is a Software issue but I would like is the photos off before I wipe. Any thoughts if I can get into it. One thing I did notice is that the computer didn't detect when it was plugged in. So I coulden't get photos off. She/I want the photos off BEFORE we wipe. Any thoughts?
TL;DR Powers on for a min but will not stay on. will not charge. Can boot into recovery mode. Rooted and unlocked, OS 4.0.4 w/ telus.

[Q] Screen not lighting up after screen replacement.

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?

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.

Shorted power button?

My a50 keeps flickering but not in a way that would make you think that the LCD has a problem.
Last night it poured really hard. My clothes were all wet and my phone was in my pocket too. Worked fine until just an hour ago. It's as if the lock button was being pressed at 20 times a second. Whenever it stops and I get to unlock it, it locks itself after a couple seconds and it just flickers over and over again. rinse and repeat. I took off the case and of course, there's moist mostly at the bottom and some to the sides. (not sure if the moisture was from last night though.)
The only way i could restart it is by holding Vol- and Power buttons. Screen is pretty much fine when displaying the Samsung logo, which makes me think it's not an LCD problem.

remove your rear panel, and with the phone shuted off, heat him, and leave at lest a couple hours opened, until it dry totally

I just plugged the phone in to charge it and the problem just went away on its own. I'm just going to assume that charging it "un-shorted" it.
