Hello,
my volume up button does not work, but i think i know what the Problem is. But i need help by identifying some components.
The board on the picture is not the broken board, but one from the same revision.
The red mark shows the position of the broken parts.
Thank you!
My phone also have this kind of problem, the volume-up button is hard to be push but there is no broken thing.
More pictures
I made one more Picture,
and i think that could be some kind of diodes...

After I have changed the broken display on DHD for the new set: Display + Digitizer, the new display doesn't work.
When I press start the vibro works only for seconds, and then I hear the system boot soud, but there aren't any information on the display, I can see only the backlight.
What is the problem?

I dont know too much about the hardware side of phones, but I know a lot about computers so I may be of some help lol
How many wires/contacts are there between the display and any external components such as the motherboard?
If only one, make sure it is plugged in correctly, the right way round, and plugged in all the way.
If there are more than one, make sure that if they have the same connector that you havent got them mixed up, such as the one that controls what displays and the one that supplies power.
This is all I can help with, sorry.
Thanks!
There is only one contact between the display and the motherboard.
I have connected the old broken display... got the same result - no info on the display. ((
Hi all,
I've had some problems with my S3 power button. It's behaving like it's being pressed when it isn't. Just slightly brushing it, without depressing the button, is registering a press. Pressing the button is behaving like the button is being held.
I've read a number of possible fixes. I tried software options, just to be sure (cleared cache, factory reset). But this is almost certainly a hardware problem.
I stripped the phone down and the physical button itself looks absolutely fine. It is interacting as it should with the internal button on the motherboard. The issue seems to be that the internal button attached to the motherboard (the little white button) is registering clicks even when it's not being fully depressed.
The phone did have some water damage about 6 months ago. I wonder if this could be causing the the phone to mess up now?
I even tried a fix that many people seem to think works: smacking the crap out of the power button itself. It had no affect on my phone - I think that "fix" that is for a power button that is stuck depressed and not a power button registering phantom clicks/being hyper-sensitive.
So I suppose I have the following questions:
1) Has anyone else experienced similar problems and, if so, did they get it fixed?
2) My plan is to try replacing the motherboard/logic board and see if that helps. Does that sound like the best fix or is it overkill?
3) If I'm replacing the motherboard, does it need to be an I747 motherboard or will any S3 model work fine?
4) What's the best source for a motherboard? I don't mind if they're used or refub so long as they work.
Any advice you can offer is welcome.
Cheers.

I had the exact same problem with mine, and unfortunately there's not much you can do about it as it's a hardware defect. I haven't tried replacing motherboards or anything, so that might help you. What I did to help with the problem was rerouting my power button to my volume up key so that I can use the power button as little as possible. The only time I use the power button now is when I need to power it on - which causes reboot loops sometimes.

Sucks.
I like the sound of your work around, though. Was it pretty simple rerouting the power button?

Ditto, my power button is borked too. Ended up doing the same thing but I don't use my power button at all. I just use rom toolbox to reboot system/into recovery
Rerouting was simple for me as it's baked into the settings in the rom I'm on (ground zero) as it is with most custom ROM'S I've been on. If you're just running stock I'm sure there's an app in the market that'll work however I'm drawing a blank ATM

I'm running CM.
I've had a look through the routing options. What I can't locate is a way to disable the power button completely. My main problem right now is the phantom clicks. I'd rather that button be dead.
Anyone know of a way I can make that happen in CM?
Nevermind. I just physically removed the power button. That did the trick.
For anyone interested, you can replace a faulty power button on the motherboard pretty easily and the parts are cheap. If I wasn't due an upgrade in 4 months I'd probably do that. No need to replace the whole motherboard.
Does anyone know the app to reroute the button? I too have the same problem.
Hi all,
My wife's G3 power button isn't working. The volume buttons are though which I find a bit odd. In order to turn on the phone you have to plug it in and unplug it during the battery load process to turn it on. I saw a couple other similar threads on this but the lg pc suite didn't work
I did open up the phone and replace the screen. I have also cleaned the contacts and used my power button (I have a G3 as well) to try to fix hers and it didn't work which seems like it could be a software issue or something that isn't connected properly inside the phone itself.
Any ideas?
Hardware
I think you have similar problem like I have . If you opened the phone in that area where the camera is(the front camera flex cable), there are small , very small parts , in my case I wasn't carefuly and one is now missing when I tried to take of the front camera ,I broke one just one little piece(very little) AND THE VOLUME DOWN is not working anymore .Take a look if you have all that parts. And if you are also missing one that's the similar damage. Micro soldering could help in your case. Sorry for my english.
My volume rocker stopped working, but the power button still works. I can still adjust volume with the system settings. Any idea how to fix this? Most of the time it's not an issue, but I wanted to clear the cache after installing the latest update, and that's how I found out it didn't work anymore.
Any ideas on how I can bring it back? If not, does anyone know where to buy parts fix? I've opened the Note before when I replaced the battery last year, so I think I could do it if it isn't too complicated.
thank you
It could be a software issue and might work again after factory reset. As there are two switches involved, volume rocker just becomes unidirectional, normally,when it's a mechanical/electrical fault. I'm not sure, but I think the power and volume switches aren't part of a separate assembly, which could be replaced, but soldered to the main pcb. This requires decent soldering skills, which some repair shops have. For Samsung service, it would mean replacing whole pcb or device.
Basically, I changed my broken screen (LCD + digitizer) with a new one without the frame. After reassembling the phone, the power button refuses to turn on the phone (it is completely unresponsive). When I plug in the charger, the phone charges, and I can also access the fastboot menu if I hold vol - when plugging in the charger. Both volume buttons are working, the screen and charging port is functional (battery appears to be fully charged as well) so I have no idea why this happened or how to fix it. Has this happened to anyone else? It appears to be a hardware problem (I think) but I really need help from anyone who knows how to fix this problem. The phone was working fine before the screen replacement so I'm not sure what could have gone wrong, please help.

I don't think anyone can help you with a hardware problem. I have a software fix that can give you a invisible softkey power button. One SystemUI.apk should put it in the far upper right hand side of the statusbar, the other on the far right hand side of the navbar.

Thanks very much. Well the help I'm looking for is to if anyone else experienced this problem and how they got it fixed.
Edit: well I got the phone to start up, I booted it from fastboot (via a pc). I downloaded the apps and tried installing them but it kept saying they were corrupted and could not be installed, do I need root access?
Hello Propaway did you manage to get your power button fixed? I'm having the exact same problem right now

The power button on the board itself seemed broken. I ended up using an app to reroute the power button's function to one of the volume buttons. As with getting the phone itself on, I used fastboot to power on the phone. Have you managed to fix yours?
