No sound after screen replacement (solution?) - X Style (Pure) Q&A, Help & Troubleshooting

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

Touch screen stopped working :-(((

Hi,
The touch screen part of my universal has ground to halt to the point that it won't work.
There doesn't appear to be any cracking and I don't recall dropping it or sitting on it.
I work a fair bit outside and can get quite a bit of dust and dirt in my pockets and am wondering if it could be due to dirt getting into the connect on the hinge.
Has any one else come across problems with the hinge?
I'm reasonably adept with a screwdriver - are there any things to watch out for when disassembling to check it over?
Hi..
If u can open with the Universal guide posted in the forum then try clean ing the connectors on the Right and Left of the Clamp Shell part with Iso Propyl Alcohol.
Before opeining you can try pressing mildly with yr fingers, at all the forur corners..it can start working..else do the above...
Hi,
OK, the screen seems to be working OK this morning, however I seem to be getting a sort of ghost effect where it appears as though the phone icon and the volume icons are getting pressed resulting in the volume controls and the phone/flight mode popup appearing on screen.
I guess it is all down to dirty connections.
Do you have a link to the thread about dismantling the hinge, I can't seem to find it.
Thanks.
re isopropal alchol
only use 99% alchol to clean contacts anything below that can cause corrosion on printed circut boards and contacts.
any progress yet.
mine stopped working today too.
but when i took off my screen protector, it worked for a while.. now its dead again.
I think the screen protectors may cause this problem, as I too had this problem with a screen protector; but when i took it off it would work and and off. I cleaned the screen up and after a few hours my screen was working again!
being in Australia I go to the beach allot. with my jasjar.
the sand gets stuck in the sides of the screen putting pressure on the screen and disabling any input. just a thought that it could be the same with u.
hope u sort it out, otherwise claim it on warrenty sooner than later.
The problem I have with the screen is that occasionally the touch screen side of things appears to stop working and also the the volume, wifi and phone dialogs keep on appearing as if I am pressing the relevant icons in the top bar.
I'm guessing some dirt has got into it somewhere or there is a loose connection, but am struggling to open up the screen's case to inspect it.

i took off my screen protector and it worked an hour...
got home, prepared to go to the T-mobile store.. then cleaned my screen ( without protector ) with a small cloth and it was working again.. so weird..
lets wait and see what happens ..
It's not really that weird: If some dust, or something equally small gets between the screen and the plastic frame, it can put enough pressure on the screen, and so the touch screen takes it as a constant (or intermitent) input, invalidating any other action on the rest of the screen.
I just received my Aquapac waterproof (and sand/dustproof) to use my Jasjar hapilly in the beach! :lol:
oh so annoying, my volume sliders keep popping up now..., as if some one keeps tapping, cause when not in Land scape mode when i open the "START" menu. it scrolls down, the same input/tap as wher the volume is in Landscape mode
There must be something wrong ... my screen still isnt working properly
one possible solution for touch screen not working
guys.... although I dont need to register onto this portal and it took me 15 minutes to register (fault of my own) but I got so much relieved with the solution that it deserved 15 minutes of my effort ;-) I hope it helps someone...just like it did help me....
I own a P835 Asus mobile and from past 2-3 days was having problems - start menu continuously appearing and my taps not getting recognized. Since yesterday my screen suddenly stopped responding to any taps or scrolls altogether.... buttons were working fine but not the screen..... i spoke to the facilities centre this morning and was about to take it to the shop but due to my laziness...didn;t go.....
Thanks guys.... what you mentioned above is very correct.... it was just a tiny molecule of dust that the screen was interpreting as my input and finally refusing all my taps..... I just cleaned the screen and the speaker side with the mere stylus n things started working.... thanks a lot.... more than laziness was this worry cause I just bought this piece a month before....
so people...before takin it to the shop....try this one too.....huhhh.....

Attention with clicking screen and dust under it !!!

Hello,
I got my N1 1 week before, and i'm really satisfied with this phone.
Since the first day that i got it, i tested it by applying pressure to the corners of the screen, just to check if it had any problems of clicking screen like the other users reported, and it was ok, no clicking and everything normal.
But today, i tested it again and i noticed that it clicked near the touch buttons at the bottom of the screen I applied pressure on it, and it seemed like it glued again and didn't click anymore, after several hours it begun to click again
I think i will apply the hairdryer method, before dust goes under my screen.
I just opened this thread to warn the other N1 owners, to check their phone again, so you are all sure that you have no problems with your screen.
Best Regards!
What's with this clicking?! I don't understand where you see the problem
Thats a good point cause I just got the N1 couple of days ago and noticed a clicking sound on the top area. Didn't know this was a known issue. Gonna have to look into it further.
I tried telling you guys in the thread I started (the other one about the dust under the screen), where I first suggested using a hairdryer... that everyone should go ahead and warm up the screen and make sure it's sealed properly. The glue has to be warmed up well to really get tacky so when it cools it will stay sealed since it's porous.

Yeah I did something like that. When I was leaving work I figured if I crank up the heat all the way up and hold the phone in front of the vent it might achieve the same thing and it seems like its good now. I don't here any clicking any more. I actually realized it was clicking from the bottom area as well aside from the top but it seems good (hopefully).
What exactly do you guys do to get that clicking sound? You press the edges of the screen? Applying a lot of pressure, or the usual? I don't seem to be getting anything weird, but I'm not pressing too much either.
You have to press at the corners with a good deal of pressure to hear the clicking.
Hm, I don't seem to be getting any noise. Is it loud, or barely noticeable?
Also, if I start to hear it in the future, is it an indicator that I might get the dust problem? Should I heat it with a hair drier? Won't that melt the plastic parts of the phone?
Press hard then let go and you may hear a very faint click. You have to listen for it. If you hear nothing then I guess your unit is fine.
Hairdryers shouldn't melt the plastic components, but should be hot enough to warm the adhesive up.

Ah, sounds like breaking the glue under the screen or something..
I used the hairdryer and it seems to work for a short time on the 4 softkeys.
Will try the upper part now
Did the hairdryer thing a month ago and its still holding strong
This message was deleted by its author
I am having trouble with this, after reading this thread I noticed the 2 bottom corners of my screen do click when pressing down on them hard, so took out the hair dryer and did each corner for about 2 min on full heat full blast, screen was hot to the touch, applied firm pressure while it was cooling afterwards, and there was no clicking at that time.
Now afew minutes after it is still clicking.
How did you guys do it exacly?
edit: nvm got it, had to hold down harder and right at the edge of the screen.
Yeah Mafi0s0, thats what i did too. I realised my screen clicking again after doing it the first time. Doing it the second time - it required alot of pressure, but doesn't seem to clicking anymore.
Thanx for the tips guys, I also had the same problem, but applying more pressure fixed the thing.
Mine also had the clicking at the bottom, and i have some dust under the screen.
It fiexed for now .. but i will probably disassemble it to clean all the dust if it gets worst.
This hair dryer method hasnt worked for me at all, I have tried 3 times, I just checked then and the clicking is heaps bad, its very loud. I am gonna get dust under my screen for sure if I dont fix this.
How have you guys who have been successful done it exactly?
Today I noticed 2 very small dust particles under my screen. After seeing this thread I did the corner test and it turns out the the bottom right of my screen clicks. I did the hair dryer trick and it seems to have fixed it.

*POSSIBLE* fix for Newton Rings

Okay, so lately my screen's becoming more and more out of alignment. I've basically had to use the black frame on the right hand side of the phone to click anything on the right that needed to be clicked.
Then last night my phone froze while rebooting, wouldn't show the boot animation, just the welcomehead image and froze there. Needless to say I thought something's up. Long story short I checked everything that there is to check and ended up having to hard-reset.
While flipping my phone around through all possible dimensions, i noticed the oily looking stain that is the well-known Newtons Rings problem.
I wasn't willing to be without my beloved Blackstone for a warranty repair and was about to jump on eBay to look for a replacement screen and digitizer, when I remembered something that fixed the touch screen in my old Sony Ericsson P900. So here's what I did that has so far fixed my newtons rings and returned the more soft-touch feel of the screen.
WARNING do the following at your own risk!!! I will not be held responsible for you killing your already dead, Newton Ringed screen
* First, be sure you have a screen protector on. I have a feeling that not having the protector on will damage the screen further.
* Grab your trusty $2 Bic cigarette lighter.
* Hold your phone on such an angle that the oily-looking Newtons Rings are visible. The right amount of light, from the right angle will show them up like the dog's proverbials.
* Ignite the lighter and hold it so the flame is lightly touching the area that has the problem.
--You won't see the rings disappear, more like they will start moving--
* Move the ignited lighter until you have moved, or removed, the oily looking problem areas.
EDIT 29-07-2010:
* Try not to hold the lighter too close for too long, otherwise you may end up needing a new screen protector
NOTE: I do NOT guarantee this will work for you, however, in my particular case, the rings appear to have gone, the screen is now once again soft to touch and the alignment seems MUCH better. It has now been approximately 12 hours since I did this, and so far, so good. All problems are still gone, no visible rings, and the screen is still far more responsive, almost like new.
Newton Rings
So did it fix the issue permanently?
Well, it sort of has succeeded. While my screen still has a huge patch of Newtons Rings (approximately an inch and a half long, by about three quarters of an inch across, they came back after about a month or two) the screen is still functioning, the "soft touch" I mentioned in my first post has nearly dicipated, but it still works. Every now and then the screen will act as if it's stuck down towards the bottom of the screen, but simply rubbing it with a cloth and some mild pressure (just like when I clean it) is enough to bring the screen back to working.
At the very least, it has given me time to save up for a new screen. But I won't be replacing it until such time as the next big change pops up in WM6.5 builds and I cook a new ROM. At this point I'll be completely disassmbling the whole phone for a thorough cleaning. While I'm at it I might as well replace the screen and keep the N.R one for a backup.
To put it simply, the screen is still working and I have no need to replace it as yet.
P.S I'm no longer using a screen protector, I don't care if it gets scratched up now, because it will be replaced, but not until it 100% needs it. I will however put a new screen protector on, if I have to do the lighter trick again.
Thanks Swarvey, got newton rings and helped remove the with the lighter, however i will hav to replace the screen protector.
Cool, glad to hear it wasn't just a once-off that it worked.
I never burned/melted my protector by doing it, but you might have different results with the much higher temperature you subjected yours to.
Keep us posted as to how well it works for you.
In fact I know a less dangerous way to eliminate those rings. I was exactly in the same situation with my HTC Touch HD. I just used some Scotch tapes on the screen, pull the screen to me , and with a lot of patience, everything as desapeared.
It works again !!

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:
http://i50.tinypic.com/mmsa36.jpg
http://i47.tinypic.com/sl1kdx.jpg
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...

Having a few problems.

Got my Nexus 7 a few weeks ago...
Here's my problems:
Rear casing creeks on the right hand side of the device (where the buttons are) but only slightly,
Lower half of the touch screen stops responding sometimes,
After exiting a game or app it takes me to the far left home screen instead of the middle one,
It has stopped rotating for some reason (probably an easy fix),
Sometimes there is the odd screen glitch, like flashing of lines across the screen for a split second,
And there is some white noise when headphones are plugged in. And i would have expected slightly better audio clarity, but its fine.
Other than that its great! The novelty of a tablet hasn't worn off yet
My tablet is running the stock JB and is not modified in anyway.
Maybe somebody could help me with some of these problems?
Thanks
To be quite honest mate, I would send it back with that many faults!
I've only got a bit of screen flicker and I'm still temped to send mine back.
Back to what you asked, you could take the back off and tighten a few of the screws up inside. (Theres a thread on here about it). But for the other ones, I don't think there are any quick fixes.
Glad your still enjoying it, personally I still can't put mine down after a month
Still having them problems, but they aren't that bad. Still using my Nexus 7 all the time.
If I open the device, won't that void the warranty?
Thanks
