The issue is as follows:
I replaced my LCD, connected all cables and connectors, put the battery in, turned the phone on. Success. Then I replaced the rear cover and all of a sudden the phone froze and turned off. I soon found out that it was one bit of the back cover causing it, the bit closest to the power button. This made me think that the power button might be pressing down, but that wasn't it because it was working fine for a few seconds. I took the back cover off and pressed on the motherboard. The phone froze.
I soon found that these tiny gold contacts were causing the phone to freeze whenever they were depressed. I don't know what they do or how to fix it. The case itself is pressing these contacts down and causing the restart.
Any help would be much appreciated.

Hey all, I'm new to the forums but I can't wait to get my 8125 working. I bought a replacement screen on ebay and a broken 8125.. on receipt all I got was a white screen, then last night I replaced with the new screen and got the cingular logo and the windows mobile "touch anywhere to set up.." message.
Well, touching it did nothing, and the keyboard didn't work, so i opened it up again.
Somehow when I opened it up, the power switch button circuit thing detached from the mainboard (and it looks like the owner before me had actually crazy glued it on!!) .. and now the thing won't power up, won't show a charge light... nothing at all when plugged in or attached to my PC. So I hope that detached power button is the culprit. Upon further inspection I saw that yet another had detached but I can't seem to find where it landed... this one for the little button next to the slider, I don't really know what it does yet.. .
.. so I guess first step is to solder that power button back on and see what happens. Does it sound like a missing power button circuit thing would cause the unit to no longer power on at all (even when soft reset when connected to PC, which used to power it on?)

Argh.. well, i'll give it a go with the power switch.... do you think it will affect the phone to be missing the comm manager switch off the mainboard too... or will the phone still function without this piece soldered on?

Yes, the power on/off button being broken is the reason why you had a white screen, and only getting the splash screen after replacing the touch screen. If you're a good assembly man, I'd suggest try to solder the button back ln place or replace the device. As for the button by the volume slider, that's the comm manager button. If you can ever get to the homescreen, the comm manager icon to activate the comm manager (bluetooth, WiFi, etc. is in the system tray at the bottom of the homescreen.
It sounds to me the new screen was replaced improperly, accounting for nothing happening when you tap it.Try re-installing the replacement screen.

Hello there guys!
Recently my M2 power button stopped working, there is no click whatsoever. I checked it up and it seems that the small metal piece fell somewhere inside the phone. I found this dissasembly video : http://www.youtube.com/watch?v=BUXSmlwUC9Q
Now here is my question : it looks like while dissasembling you are ripping the phone apart, is there any permanent damage when trying to dissasemble? I could do it by myself, pasting the metal piece inside but I m a bit concerned about damaging the phone.
Thanks
Strange Milestone 2 power button problem
Hi, I have a strange problem in the power button too, but it's very rare (may be rare just for me)
The thing is that the power button suddenly stops working. If i take off the battery and put it again the phone boots without pressing the power button, and it still not working. Then after some time, it suddenly starts working perfect there is no need to press it stronger then normal.
I can't find out any patterns in this behavior. Another strange thing that happens is that sometimes the button works intermittently and delayed. Example: I do a long press of the power button and nothing happen, then the shutdown dialog shows 2 seconds after. And some times (the most) it doesn't
I'm a little bit confused about it, any ideas?
I've new info: i can't get into bootloader mode (the phone turns on but i get a black screen with no text)
Think I am getting the same power button problem now. How did your repair go?
Same problem here now, dunno if its really related to the power button or something
completely different is going to break down soon.
I will try to replace the whole flex cable with the buttons, but shipping needs some weeks.
I recently got my G2 D802 wet in rain. It was in my Rain jacket's pocket, and got a little wet, i turned it off and cleaned it with tissue and put in a plastic bag. when i came back to home i sucked air from speakers grill and turned it on. it opened fined except touch was not working in certain areas, then I opened its back casing (its easy) and used hair drier to dry it for over 1 hour, i dint put drier too close in case phone gets too hot, but im sure i dried it well, then i turned the phone on and it worked fine, untill next day when its power button started acting weirdly. power button works fine, it turns phone off, unlocks it, only problem occurs when it doesn't turn off screen when phone is unlocked. like when screen is on. i have tried locking and unlocking in recovery TWRP and it works fine there. just having problem when phone is on. any suggestions? im on Cloudy Rom 2.1.
thanks.
PS: i just check again, when phone is locked and screen off, and i press and hold power button, it displays power off menu and also opens QUICK MEMO, so i guess when screen is unlocked , power button acts as vol up and power button?
Probably some water short circuit your buttons. A good manner of dry wet phone is:
Disconnect battery
Put the phone in rice for almost 24 hours
Reconnect battery ......Pray... And turn it on

Hey!
I have an S5 Neo at work, and earlier on Friday morning it worked great, but then the screen started to go black, first it was only random and it would go back on again. But soon i had to try remove the battery and restart it, but nothing happend. After waiting some time the screen was back on again.
So when I got home I tried my best and got the screen working, did a backup and factory reset. I was super happy and tought that it had helped, because the screen come on right away. But as soon as I put the backcover on the screen started to flicker and then turned all black again.
I managed to get it working by pressing quite hard from the rear around the camera and the simcard holder. But only temporarily.
One other thing that does seem to work is to remove the battery, hold the power button pressed for some time and then start it back up, but as soon as i press in the upper corners the screen flickers, and if i press pretty much straight on the samsung logo it goes completly black and wont turn on, until I have had the phone turned off and pressed the power button for some time.
I understand that this must be something wrong with the display assembly(loose flex or solder joint in flex) or maybe even motherboard, is there anything I could try and do at home, or is my only option to send it away and get it fixed?
Hey all,
So my dad dropped his phone and the screen appeared damaged. Tore apart his phone and it turned out the plug for the screen was just loose. Fastened the LCD plug down and put a tiny dab of super glue to keep it in place. Works great now! Cool, I thought
I cannot for the life of me put the case back on and the power button stay in place. I have no idea why, but it seems like I push on the edge of the power button and it goes into the phone, the other edge comes out, and the power button falls out.
I've watched multiple videos and the power button looks exactly the same. Anyone have experience with this or advice?
I don't know what I did but it seems to have worked. I still don't understand what went wrong the first dozen times I closed the phone up because the power button would not stay in
