Hello everyone.
The first thing I want to do is to apologize for any grammatical errors that I will do during the writing of this article. English is not my native language so I'm hopeing you will forgive it to me.
On my HTC M8 I had water damage. After the damage it was cleaned with alcohol. Cell phone was turned on but touch screen was not responding. I replaced and touch chip on the motherboard without success. Afther that I bought a new screen. Without success. Now I bought a new motherboar, with which the phone works fine, but only while it is connected to the micro USB.
When the battery is charged external, afther a few minutes the mobile phone say that it is 100% full, but after a few minutes battery starts to drain dramatically. Even when the phone is connected to the charger, in the options menu it's showing that the battery is discharging. I tried to replace the battery, but the same thin happened..
When I switched off cell phone and connect it to the charger, orange LED for a few seconds is a solid, and then show the battery warning and start blinking.
I noticed thaton the replacement board very quickly warmed processor and power chip. I also noticed that it's missing a protective aluminum cover.
Can the lack of this aluminum cover cause overheating problem power chip?
What would you recommend me to do?
I suggest you trade in your phone for a new one, because once these things get water damage (of any sort) they always start to show many sort of problems. And...yes, the aluminium cover is very important, because since the cover is metal, once it is sealed, there is always the chance that the peeled wires can touch that cover and make some sort of shortage.

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!!!!
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)...
I sold a Galaxy Note 2 on amazon and it was returned with the water indicator positive on both the battery and the phone itself. Unfortunately, Amazon overrode my decision on not to refund the customer, so now I am stuck with a defective phone.
I took it apart and left it in rice for weeks and bought a new battery because the one in there had blown up like a balloon. The phone powers on and charges and it appeared to be working fine up until I attempted to use it for a day. It crashes and the battery drains from 100% to 20% when powered back on. Is there any way to fix this device?
Thanks.
First of all im sorry to hear about your loss, The thing you have mentioned seems like there is still moisture in the phone. You have already mentioned you placed the phone in the rice, I hope you have airtight the packet as well ?? What is the temperature there? If you have a country like sun shining and hot weather then you can place your phone and battery at the car dashboard. Which will warm the phone internally.
If you have a short circuit and motherboard then you need a technician. But as you mentioned phone is working fine and only problem is draining of battery than it looks like phone have moisture.
Hi all, I dropped my tablet today and for a few hours later it worked fine but suddenly the touch stopped working and it doesn't charge. Everything else is ok the LCD the buttons even the screen rotates until it shut down due to empty battery. Now battery doesn't charge and I don't know what to do.
Any idea what happened to the tablet?

You can open the back side. Carefully remove the power connector by prying up with a small flat blade. Once removed, let it set for 10 or so minutes, then reconnect and assemble the case cover.
Connect your charge cable and wait a minute... it should show the battery charging image. If not there is damage to the device.
I use a rubberized case cover. A few times I have dropped my tablet fairly hard, and have not suffered any damage.
Hi
Got a water damaged nexus 7 2013 over here, as soon as it was dropped in water, I turned it off and dried it off before taking it apart and letting it dry out. After putting everything back together the tablet worked wonderfully and the only remainder was a little bit of water under the touch screen and I think I made a big mistake by ignoring that.
After about a week, the battery was dead and needed to be charged, I plugged it in and the led blinked 5 times which is normal so I just left it. After coming back I noticed that the tablet was pretty hot near the cpu and of course, it refuses to turn on, it doesn't blink 5 times anymore, my computer doesn't beep anymore, it's totally dead.
Things I've tried so far:
Connecting it to my pc without battery and screen connected (I know it should blink 5 times as well if no battery is installed) and nothing
Trying to turn it on without daughter board connected (should still show google screen, I have done this before) and again, nothing
Trying to turn it on without screen or daughter board (I know I had a notification that made it beep when it turned on) and nothing
I took it apart again and noticed that the connector on the actual lcd was very corroded and I just assumed the screen was causing this but apparently something else is broken as well.
Anything I can do about this?
Thanks
Hi, I'm sorry to hear about this unfortunate accident.
Firstly an advice to anyone reading it -- in such situation, turning it off is not good enough and one must disconnect the battery ASAP! That's because the power switch is actually only like a standby control and unable to completely cut off power supply. While off, full power is still available to all mobo's voltage regulators as well as LCD's backlight converter and its local power regulator. And then accelerated water corrosion and damage starts...Remove all metal shields from the motherboard and clean up corrosion residues. The LCD is gone for sure, so test it out again with the mobo and peripheral boards only, looking for the notification light's blinks. If it works, check if you can get picture over SlimPort connection.

I used a multi-meter to test the battery and the cells are @ 3.4V not sure if that's enough to turn the tablet on tough... I'm letting it charge for a while now to see if my computer picks it up
EDIT: the battery voltage when not connected to the board is 3.4V, the battery voltage when connected to the board is 0.34V. That can't be good
EDIT2: the cpu is mildly warm but the PM8921 battery management IC is burning hot after leaving it to charge for a while
