Guys, I bought and replaced the charging dock from my N9005, because mine got damaged in a tragic accident involving me, the charging cable and the phone itself... Now, after the replacement itself, I have noticed that my loudspeaker does not work at all (missed my alarm this morning, thought I overslept, but I had later on the phone in my hand and it rang... but without sound.
After a bit more tinkering, I have noticed that if I just put the back panel (the one that contains the speaker) on top of the phone and press gently, it works, but if I put in the screws and push it properly, it stops working.. So my option right now is to either leave it flimsy (too flimsy for the back cover to be put on top and still function), or to not have a speaker at all. Any suggestions, what I did wrong, or which one of the two components you guys think might have been the one to break? The new charging dock, which also contains the contacts for it, or the speaker's connection itself? I took as much care as I possibly could when I did it, but still... Help, please?
help?!

Hello People,
I've got a little problem with my hd2 ^^
Since several weeks, the plastic from the LED's was pushed inside the device and so the vibration alarm wasn't really silent anymore (since the vibrator is behind the led plastic and it touched it inside).
So now I decided to open the device an push the plastic back in it's place.
Opening the device was really hard because of the massive glue they used^^
But after some minutes I got the electronics out of the body. I cleaned it a little bit up, fixed the plastic an put the device back together.
Starting it, confirmed that the vibration now works silent again, but my screen stays black...
I really don't know what happend there , but I never touched the screen or openend the device more than I had to.
So maybe anyone has an idea?
THanks a lot.
First thing is that i dont understand where you finded "massive glue" if you just opened your phone to place back leds cover/zoom plastic. They dont use glue, only adeshive stick tape. But this is just interesting for me.
Second thing is: are you used some minimalistic bead when you placed back leds cover/zoom plastic? If you didnt, then it can drop again to inside.
If your screen is black then maybe you just acidently touched connector and ribbon cable, where lcd connects to motherboard. You must open your device again and recheck. This connector attached with ribbon cable at lcd must be sealed with yellow tape.
Hello,
sorry a meant adeshive stick tape ^^ I was just hacked off when I wrote this
yes, I put something on the led plastic.
I checked all the connectors and also watched a video where the disassemble the entire phone in order to see where I could have damaged or removed something. But as far as I can see, there is nothing loose or missing. I didn't remove the mainboard; I just took the device out of it's outside cover.
Hmm, i dont have idea whats wrong then.
I opened mine phone not once. Also replaced more 5 HD2 digitizers and lcds. All time dont had this probelm.
Are you sure you dont had static electric on your hands?
yes, I was protected against static electric.
maybe I'm gonna disassemble it totally and see if something else is loose.
Turning it on works, because the vibrator triggers once.
And I just realized that the power led does not work when I'm plugging the device in...strange
Hey i installed gingerbread android 2.3.7 on my phone again but this time im getting really weak wifi signals... i'm only 5 feet away from router. It was not like this before so i do not know whats going on ( i only dropped my phone twice)
can you guys help me? is it a software issues or hardware?
happy thanksgiving
I would recommend installing a few different roms (that are known to work with wifi) and see if anything changes/improves.
If nothing improves, maybe flash back to winmo 6.5 and see if wifi improves.
If nothing improves then, you may have damaged your wifi antennae when you dropped it then hit up T-mobile!
Best of luck mate.
Possibly knocked the wifi coax loose from the mainboard. It's pretty easy to open up an HD2 and reattach that cable, I've had mine come loose before and that's what I had to do.
I'd definitely try the steps in the above post first just to make sure it's not a rom or kernel specific issue. And if it's still under warranty, don't bother taking it apart and ruining your warranty, obviously just return it to t-Mobile.
hey can you explain in more detail how to push back the wifi coax cable your talking about
Remove the battery cover, battery, sim card, and sd card.
Remove the 4 torx screws that are under little round stickers under the battery cover.
Using an old credit card or a plastic knife, slide between the screen and the housing to release the little plastic clips one by one which hold the housing to the phone's chassis.
Take your time and be careful not to scratch the housing or stick the card/knife in too far, damaging the fragile stuff inside,
It helps to put a little pressure on the back side of the screen wth your thumb while orying with the credit card (back of screen under battery)
The wifi coaxial cable runs from one corner of the mainboard, up along one side of the chassis, is taped together with some other wires, and leads to another small board up near the top of the phone.
Check the connections at both ends, making sure they are connected firmly and are in straight.
You might want to unplug them, just to be sure and hear/feel them click into place.
Take your time, set yourself aside a nice little workspace, and if you are unsure of anything, don't hesitate to come back here and ask.
There is a disassembly video here in the HD2 section somewhere, I think it's in HD2 General. It'd be worth it to search for it and watch at least the first part of the video, just to get an idea what you're dealing with. It's not a very hard job, it should take you like maybe an hour/hour and a half start to finish.
This will void your warranty permanently though.
Thank you sir i just followed the steps you did and it fixed the problem my wifi works fine but now i have another issue....
i dont know if i touched something or disconnected something in the process but my sound, vibration and volume button does not work. External speaker is not playing any sound (no music or key button taps) and no sound is made when placing a phone call BUT the other person on the end can hear me just fine so i'm guessing i might of disconnected like the speaker. ( my assumption)
thanks again for your help
Oh and when a call is being placed or recieved the screen automatically turns off and it becomes non responsive i.e if i take my phone off the ear and want to put it on hold the screen is still black instead of turning back on
The screen going black during a call is a pretty common problem with the HD2, and is likely not related to disassembling your phone as long as the screen functions normally otherwise. Since you didn't take your phone far enough apart to affect the light/proximity sensor, I can't imagine how disassembly would have affected it. You would have to take the mainboard and screen out from the chassis to get to that sensor.
The volume problem on the other hand, is probably due to either your volume rocker not being placed correctly during re-assembly, or the speaker contacts not being aligned properly. You'll have to take it back apart and ivestigate what went wrong.
Try going into Settings/Sound, and checking that the volume is not turned all the way down. If the volume is not all the way down, then you should be able to hear sound, so your speaker is probably not aligned properly.
Does your volume rocker feel different than before? If it doesn't make a definite 'click' when you press it, then it is probably slightly out of place. Also look for any wires that could have been pinched and damaged when you snapped your phone back together.
What is a volume rocker? When i start the phone it usually vibrates once then goes through the starting procoess. Now it doesn't vibrate at all. Phone turns on and i click the volume button up and nothing happens. I checked settings and everything is up
I have the phone opened as we speak and the reciever cable is connected and the vibrator cable is connected too. I tried to use tweezers to see if i can unhook it but their on too tight so thats a good thing. The two orange dots on the volume thing.. the bottom on was slightly off so i put i centered it
Still nothing works. no vibrating no sound ( the person on the other line can hear me but i can't hear anything) but the phone works great.
Im so confused
The volume rocker is the button that 'rocks' back and forth to control the volume.
It has to be positioned right in order to push the contacts that lie beneath it.
Since your phone's apart right now, what happens when you hold the battery in it with one hand, boot it up, and press the volume button contacts manually? If they buttons themselves do nothing, then it must be that they lost their connection somewhere, you'd have to trace the wires and figure out where they're not connected. If they do work, then the volume rocker was just misaligned.
As for the speaker, it has to be that it is not contacting the two little contacts correctly. Look at the speaker and make sure it is sitting correctly in the housing, and look ffor any obstructions near the vibrator motor.
No i can't press down on the volume button ever since i opened it it hasn't fit back right. Doesn't make a click sound
and what contacts on the speaker should i be looking for? are they under the speaker itself? should i remove the speaker? Theres no destruction on the vibrator its looks though like its sitting kinda tight between that camera flash being there..the metal spinning thing on the end of it can spin 360 so nothing its preventing it from moving.
I also can use my headset and the sound and call works fine besides the going to the black screen and not responding. i also noticed my camera does not load up either. but that could probably be solved with a clean install of gingerbread nand rom
I'm hoping somebody with some knowledge of the HD2's innards can help me...
My vibration stopped working on my HD2. I found the plastic LED flash cover to be 'pushed in' (with the help of a couple xda threads I dug up). Others said it was an easy fix: Open the case and push that piece of plastic back into place.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the plastic volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But clearly wasn't just the volume rocker that was affected. It doesn't seem that I pulled anything else loose or anything like that...
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas?? Thanks in advance!!!
Snapped a couple quick pics which may help:

Unfortunately when comparing these to other pictures of the inside of the HD2 that I found online, I fail to see any differences, or anything I could have inadvertently screwed up.
Most likely you screwed up(or disconnected from motherboard) somehow your main flexboard, but your picture are not usable for this, you should take off your motherboard+main flexboard from chassis to have a full view!
You probobly just disconnected a small cable. I have no idea of the HD2 innards but did multiple repairs of small stuffs and the flat cables hold in place by a plastic clicker pull out easily - just reopen and check them all, you should be fine.
Thanks for the input! I figured it's something like that, just one small cable. But I didn't even take off the board at all... The pictures show the full extent of the disassembly... Do we still think it's necessary to disassemble it further?
I checked all visible connections, but yeah, maybe I somehow yanked out something that is NOT visible. I'll try to check again today... In the meantime, any more ideas from anyone else? Thanks!
For al that to be not responding I would assume main-flex damaged or as mention before maybe connection to mainboard got moved during pulling cover !
Volume button can be troublesome, sometimes the little plastic caps come off but if it felt clicky should be good in that respect.
also be very carefull of thin spring metal legs that contact antenna pads on back cover, one near screw above & right of vibro motor looks a to be a bit flat. They bend easily & break easily too ...
Have u tried starting up the phone without the backing? I had this issue when I painted my housing the led cover was stopping the motor from spinning but if i took out the backing it works. So I just trimmed the led cover and now it works.

Click to expand...
Click to collapse
I'm nooby with regard to this stuff; I only attempted the repair since I read in a couple other threads about multiple self-proclaimed non-super-tech savvy people were able to open it up and move the plastic LED cover for an easy fix.
So what exactly am I looking for with regard to the main-flex? Where is it? I thought I wouldn't really see that unless I removed the board which I haven't done... is it still possible I knocked it loose or damaged it? I didn't think that would be possible since I ONLY removed the back cover (though it does take a slightly uncomfortable amount of force to do so, so I guess anything can happen...).
If not the main flex cable, is there anything else specific to look at which may be disconnected? It seems to be all the stuff at the top of the phone that fails to work (camera, speakers, vibration, flash, volume keys). While the stuff on the bottom (other hardware buttons, charging jack, headphone jack, etc).
THanks!
I have given up. After being stumped briefly how to hard reset the device without the volume keys working (I have Android installed), I was able to do it via ADB from the Android dev kit.
To ebay I go...
Hi all. Had to replace my screen and as Nexus 4 is so old, decided to DIY it. All seemed to go fine, but the microphone wasn't working. Tightened all screws up and it came back to life. Now it's gone again.
It's not like it's entirely broken - I can see the sound graph around the microphone reacting to sounds, but it doesn't seem to be picking up enough volume. I've tried wiggling everything that moves to see if it will bring it back to life but it only occasionally works and quickly seems to go again.
Is it looking like I need a replacement charging board?
Hardware Issues after replacing battery, USB/Audio connectors & main board
Need some help, and figured you guys would be the right people to direct me on a fix or at least narrowing down the cause of the problem
Phone - Verizon G2 v980
TLDR - replaced 3 different parts, and now phone display won't show anything - just black.
It all started when I was having some audio issues with the headset jack being loose, and headphones and aux output disconnecting easily and often. It was pissing me off, so I decided to replace it. (I'm no stranger to tearing apart and fixing small electronics but I never worked on the LG G2.
I figured since I was going to open it up, I'd replace the battery at the same time, and bought both off ebay.
When they finally arrived, I opened up my phone following a couple videos I'd found online (btw, no little black screw in mine, as it was a refurbed replacement via squaretrade.)
Unfortunately, through a combo of cheap 3rd party battery with a very stiff ribbon cable, and my clumsy fingers, I managed to destroy the logic board's battery connection port.
So I went on ebay to find a new board... I found a used verizon 32gb (mine was 16gb) board and got it delivered.
When I put it together, something is not working right, but I can't be sure what it is...
I think the board is bad, but am not 100%.
Screen is black
I can connect the phone to my computer, and it will autodownload the LG Verizon software, and show up in my file explorer. There's some files still there, but it looks like it was attempted to be cleaned, but not factory reset wiped (some personal data still there) but the dates are all showing 1970ish....
I have the phone connected up to the original charger, and the notification light pulses light to dark red as it charges up.
When I plug in the charger, I hear a buzz, and sometimes even a tone.
I hold down the power button, and eventually it vibrates again, and the notification LED pulses blue & green, and there's a brief backlight looking light with some vertical lines, another buzz and black screen. I'd think it was shut down, but it still shows in the computer, and the light to dark red pulsing continues (charging?)
knock on doesn't work
Should I return the board?
Saw some other threads about the proximity sensor, so I can check that out, but I didn't touch the screen...
Thanks in advance!
Update
No difference with proximity sensor disconnected.
With the old board in with busted power connector wedged in, it does nothing, except when plugged in, where it buzzes repeatedly.
