mic gradually died

Please, help!
I recently replaced the screen (both LCD display and digitizer+glass) on my AT&T HTC One X. Everything was working for 1 week. A week later people I called started hearing heavy noise instead of my voice. Sometimes they could barely hear my voice through the noise. Redialing and occasionally rebooting fixed the issue. But over the last 2 days the issue got worse and worse. I started testing with gTalk voice and video calls, and with voice recording app. 1 out of 10 times my voice could be barely heard through the noise. And sometimes it was complete silence. There is no problem while using headphones with integrated microphone.
So I took the phone apart again. I found that the bottom, main, microphone is on the flex ribbon cable with navigation buttons and their lights and the plug for the vibrator. This is the part http://www.globaldirectparts.com/HTC-One-X-Navigation-Light-Flex-p/htc748178.htm. (Note that it is very different from the international One X)
When replacing screen I never touched that flex ribbon, it is still glued to the frame; I never unplugged the vibrator. I did unplug and later re-plugged the flex cable to the motherboard. Both navigation buttons with lights and the vibrator worked and are working just fine. But the mic now seems to be dead. And I cannot find this flex ribbon cable anywhere.
1. How else can I test the mic and make absolutely sure it's a hardware fail?
2. Is it possible to replace just the mic and not the whole flex ribbon cable?
3. Where can I buy the replacement mic or ribbon?

This isn't a q and a section.

If I understand you correctly, you are suggesting to steal. No, thanks.
Also, I purchased the phone with cracked screen from a stranger, then replaced the screen myself. So it's safe to assume the phone is out-of-warranty.

I tested the microphone with the app Z - Device Test = complete silence.
Using speakerphone during a call makes the phone use the top mic, and it works just fine.
My next step is to factory reset. If mic doesn't work, then I'll flash a custom ROM, to ascertain that the problem is not in software/OS/drivers.
If nothing helps, then I'll have to replace the whole navigation light flex ribbon cable. I found it here www.etradesupply.com/oem-htc-one-x-navigation-light-flex-cable-ribbon-at-t.html for $21.62 + $14.99 shipping = $36.61 Ouch!

I installed CyanogenMod 10 stable -> mic is still dead. I also found out that CM does not switch to top mic when in speakerphone voice call, as the stock Sense does.
I unplugged the navigation light flex ribbon cable from motherboard - button lights stay off, as well as the vibrator. I re-plugged the cable -> light and vibrator came on, but the mic stays dead.
I cannot think of anything else, but to replace the navigation light flex ribbon cable.

i am in the same boat, i found 2 other sites beside the etrade...:

Argh! I already ponied up $37 to eTradeSupply. I got the order confirmation email and 12 hours later the following update:
Your order # XXXXXX has been
Processing

(long overdue follow-up)
I received the flex ribbon cable with navigation buttons from eTradeSupply. I successfully replaced it and had the mic repaired. However, I bend the (freshly replaced screen) so much that I ruined some connectors - now the left third of the screen shows black and the other two thirds and much darker. Hard pressing the bottom left corner fixes the screen brightness for 1-2 seconds only. I don't want to invest in this phone anymore. If anyone wants it for parts, PM me.

You should donate it to the S-OFF thread. Sales are not allowed on this site but I don't think donations have been banned.

Broken lcd screen/digitizer

So, a few weeks ago my phone started acting weird. When I would open the keyboard, my screen would turn off. It did this for a few days, then it got worse. I couldn't even use my keyboard. Then, my screen would randomly start flickering... and now it just won't come on at all. The phone comes on, I can see the notification light blinking, but the screen won't come on at all.
I'm going to buy a replacement part for it, but I'm not sure if it's the digitizer or lcd screen. Anyone know which one it would be?

...at first...no digitizer, no display.
open the phone and check flex cable connection - maybe is poor connected.
If this not help then check flex cable.

yeah i was thinking it could be the flex cable, but i haven't played with it much yet. maybe i will tonight and see if my flex cable is disconnected/bad... but i couldn't find any replacement flex cables (without a lcd display or digitizer) anywhere.
IF it was the lcd, what would the symptoms be?

check flex connection and let me know
Was you photon disassembled?

yessss no problem

i've always wondered if there is actually some way to buy flex cables replacements in case they break... so far, i have only found the whole frontal assembly which costs quite a lot and that includes the flex cables, turning what would have been a couple $ repair into a very expensive (and probably not worth) one

i got an old working photon q that i was keeping myself for spares in case...
if you want a part then PM me. x

need advise

i'm confused how to release replace my flex cable

Is there a tutorial how to replace the flex cable with front camera as selled by parts4repair? Or is it really foolproof?
It seems to me like I'm facing the same issues as described in the start post, only in an earlier stage of degeneration of the flex cable:
1. Suppose, the Photon Q is turned on and in operation. When sliding out the keyboard only some millimeters, the screen goes black. If I press the power button at this stage (keyboard slid out some millimeters, screen black), the phone seems to crash and reboots.
2. Suppose again, the Photon Q is turned on and in operation. This time I slide out the keyboard all the way (no matter how fast). The screen goes black. Pressing the power button at this stage doesn't show any effect. Only after pressing it a second time, the Photon Q is awake again, showing me the lock screen - apparently no crash and no reboot!
3. Suppose, the Photon Q is turned on and in operation. I turn the screen off by pressing the power button once, then I wait for some seconds and slide out the keyboard all the way. When I turn on the screen this time by pressing the power button, the lock screen appears as expected and everything is working fine.
All these scenarios also work the other way round, i.e. you assume the keyboard is already slid out all the way and you perform the slide-in movement. Also, this is not a software issue as it behaves analogously during reboot or in recovery mode. Furthermore, I opened my phone. The flex cable was connected properly and I couldn't see any damage to the flex cable. So it seems to be an internal loose connection of the flex cable.

[Q] One X running CM 10 mic problems.

I just recently replaced my screen/lcd/digitizer on my phone and my microphone no longer works. The microphone flex cable seems to be in good condition as the vibration still works. I'm stumped. I hate to go back to my buddies old phone.

If you're s-off you can RUU to rule out software but it's nearly impossible to tell online what would be causing it software wise. Even if the flex cable looks fine, it can still be damaged. Also, the cable could come loose while putting it back together. These are things we cannot tell from miles away though.

Unfortunately, my phone is s-on. If it is the flex cable, then shouldn't my soft buttons not light up as they are the same flex cable?

That is not necessarily the case. I would S-OFF and RUU though if you want to rule out software.

I have the same problem as the OP. No mic after screen replacement. Unfortunately, I replaced the screen, went S-OFF and to RUU 3.18 all in one fell swoop so I'm not certain if it's a hardware or software problem.
Update: After replacing the Nav Light/Microphone flex, works fine. (AT&T version)

Elimination of Faulty Hardware

Got my one x with a rather ****ed power button ribbon cable. Its mostly operational except for a couple issues. My recent apps button has never been lit up from the day I got the phone and removed the outer shell to inspect the power button. Leading me to believe the pry tool damaged the component directly related to the recent apps button. The button works fine just won't light up. Is this piece easily replaced, and what is its name ? The second issue I first noticed after installing CyanogenMod. Nobody can hear me at all while on the phone, speakerphone or not, headset even. Now callers can hear me when on speakerphone and headset on any sense ROM, nothing AOSP. Not sure how many mics this phone has, what should I look into replacing?

[Q] sensation xe digitizer replacement gone a bit wrong

A friend gave me an XE with broken digitizer so a gave it a shot. Unfortunately I wasn't very smooth removing it accidentaly cut the cable i point to on the snapshot. My problem (?) now is that everything seems to be working as it should and I don't know whether I should spend more money replacing the broken thing, because I dont even know what is not working. Apparently, I cut the microphone cable, but microphone is working perfectly, so what is wrong?
