Need advice: broken speaker

Hi,
The speaker on the outside of my universal (the onw you hold against your ear with when the screen is on the inside) is broken.
That started as something like a bad contact (if I pressed the phone against my ear it would work, otherwise not). Now it is not working at all.
The speaker on the LCD side is working fine.
The advice I want:
I took a look at the service manual PDF I got and disassembling the phone to reach that speaker is a lot of work. I do have experience with diassembling electronic devices and even do some soldering, etc. However, my doubt is this: I have a phone which does work, but the way I like to use it to make calls does not work.
Question 1
Is it worth the trouble to diasassemble the whole device just to check if it is indeed a bad contact due to i.e. dirt? Or will I actually risk breaking something off, which will render the complete phone useless? Looking at the service manual, one needs to use a plastic tool to actually open the phone. How easy do the hinges break off?
Question 2
Has anyone had a similar problem? Was it easy to fix?
Thank you!
Cheers,
vma

you dont need to disassemble the whole phone just disassemble the screen . It isnt that hard to do, just remove all the screws from the screen . The screen casing is difficult to budge at first but once you have freed part of it open, the rest follows quite easily.

Hi,
Meanwhile I couldn't resist and opened it...
...and I found the guilty part.
It seems that the outside speaker is actually attached to the case and uses a contact connection to the PCB. This connection is made by to metal plates, which are tiny and folded. They will compensate the varying pressure made on the case (i.e. when you press it) and I guess with time they tend to break at the fold.
This happend to one of the two contacts. First I tried to fix it, but the truth is that it is so small that it is quite impossible to do anything about it. I considered soldering a small wire, but that would require to solder the other end to the pin on the PCB, which then would mean, I could no longer use a regular replacement speaker, if this one had any other fault (unless I could clean the contact again, but trying that, I could break something else, also).
This means: now I am not able to use the outside speaker anymore...
Question: where can I purchase a replacement one? Would anyone sell me one from a broken Universal (for a symbolic price - anything over 10 Euro is too much, as I would prefer to just buy a another second hand Universal)?
And as I was figuring this out, I used the occation to fix that loose stylus!
1) Open the underside case (4 screws, then open the case all around with some thin plastic).
2) Roll a little bit of celotape and place it between the case and the pin that fixes the stylus in position.
3) Try it out until it is OK.
4) Close the case and that's it!
Cheers,

Hi buddy, in fact I did have the same problem that you're having some months ago, my uni fell and since then the problem just got worst, until some day a couple months ago I opened it and fix it.
It's just like you say, the little golden plated contacts wore off, then the little speaker's metal plates just were too high to make any contact against the pcb, it's really simple, just pull the plates gently away from the little speaker, do clean both sides of the contacts (pcb and speaker's plates), i did this with a little xacto knife (be very gentle), and that's it! It worked just fine.

The problem is that in my case one of the metal plates broke off.
I tried to fix that, but it is to small for me to achive anything.
Cheers,

[Q] HTC HD2 weak wifi signal

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

HD2's innards: Attempted vibration motor fix gone horribly wrong.. HELP!

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.

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...

No sound after screen replacement (solution?)

So my poor Moto X is now on its 4th screen (dropped and cracked, split screen static thing, etc. ) and I ran across something tonight that may help others.
I have taken the phone apart many times now, what with actual replacement of the screen and trying the old ribbon cable adjustment trick. (which rarely helps).
Tonight I popped in the new screen and was pleased that it fixed my static split screen issue. But a few hours later I noticed I had no sound! Practicing my Google-Fu I found several instances of screen replacement killing the sound but no solutions. Searching the forum here I couldn't find any help either. WTF?!
After taking the phone apart several times with no success I put on a long You-Tube video with sound and started squeezing and pressing on the back of the phone and I got a small squawk from the bottom speaker. I continued squeezing and put in a few screws on the ends and as I tightened them much more than I normally am confident in tightening I got crackling sound from the top speaker. I put all the screws back in and tightened them as much as I dared and now I have sound, better sound than I have had for a while.
I think most of the eBay replacement screens are probably factory seconds and maybe the threaded post inserts on this one and others are a gnats ass longer than they should be or something.? So if you replace your screen and the sound stops, try tightening the screws a little more.

I remember getting the same problem when I replaced​ my screen. I don't know if it was a fluke or not, but those black speaker screen covers block the the magnets from the screen. I think the speaker magnets and the screen interferes somehow.
I forgot to place those black screen covers, and it didn't work. I reopened and put them on, it worked. Give it a go, doesn't hurt to try

One plus 5 Camera and flash light notworking

Hi ,
My speaker at ear was not working due to oil went inside ear speaker. I removed the speaker and cleaned and put it back. Now the issue with speaker is fixed. But Camera and flash light stopped working. Error is "Failed to open " camera. Also YouTube app stopped working.
I tried keeping back side open of and It is working when screws are not inserted. While inserting screws it stops working. What may be the reason for that

Right, I spent the last few days wracking my brain over this problem and similar, so hopefully my solution actually sheds light, and I think in your case it might!
I needed to replace my screen so had to do a full opening. I thought maybe I damaged the motherboard or something as I stupidly had to remove the screen first (not good) so thought the heat I applied did something to the camera module. Nope. Basically, when I put the phone back together the following wasn't working: Camera, Flashlight, YouTube. The camera would fail in safe mode, it would fail in the *#808# hardware check, I did a factory reset multiple times, flashed different stock ROMS (my phone is vanilla and not rooted, so I only used official ROMs)... not a single thing helped. I realised very few posts complaining about the issue actually transparently say they opened their device, for embarrassment or ego, or I dunno, but it was super vague as if the camera/YouTube failed all on its own, which is odd to say the least.
Anyway, in my case, do not tighten the screws tightly when you reassemble the phone. This is part of the problem. Screw enough that it catches and then leave it. Don't screw it any more. Next is where yours might relate to mine in terms of camera. There is a tiny wire that trails from the motherboard (near the vibration motor) down to the loudspeaker. In my case, that wire was getting pinched when I put the loudspeaker module back in place. This is what caused my issues for the most part. So check the wire is seated in the frame outlines where they should be.
TLDR: Check the very thin wire from mobo to speaker - that might getting pinched during reassembly.
I really hope this helps you because it was getting on my nerves that noone suggested it. And if it does not help... I'm sorry... I hope you find a solution soon!
