[Q] LED Torch/Vibration problems after falling - HD2 Android Q&A, Help & Troubleshooting and Genera

Hello guys, so my phone fell of my hands yesterday and landed on it's screen. It's cracked but still working, so im waiting for the ebay replacement to arrive. I've already disassembled it, and put it back together, just to see if it was hard. After all that the vibration motor is too loud, i mean, really loud, it was much quieter before.. And the LED Flashlight doesent work, says torch is on but no light.. Could something get damaged or disconnected when i disassembled it? Thank you.

This has many possibilities, and one cannot judge without seeing the actual device. The falling could have damaged it, the dis-assembling maybe .. maybe you stretched, ticked or disconnected something. And I have no knowledge in the device's hardware so I couldn't tell where the issue(s) could be from, and I'm quite sure neither could you. My suggestion is take it a repair shop, let them see what's wrong.
Just my 2 Halalas.
Edit: This thread is now cursed.

Qtek 9100 - Mic & speaker dead, for the 2nd time

Hello all!
First, thanks for an awesome forum! It has both helped me tweak my Wizard, and also get help when I have needed it.
Well, I have no choice now but to ask here. Last autumn, my warranty was almost up, and a wierd problem presented itself. The mic and speaker suddenly just stopped working! The sidespeakers still work, I think, because the phone rings when someone calls me. But the caller can't hear me, and I can't hear the caller. And there isn't a hint of sound in it, no static or noise, there simply is nothing.
As there were only a few days before the 2 year warranty was up, I ran to my dealer and turned it in. A few weeks later, the phone returned, working again. But now that I come to think about it, I don't remember if I got a replacement or if they actually repaired it... It looked a little like they handled it rough though, maybe it was another phone... Well, that's not important right now.
The same thing has happened again! Summary:
1. Mic & phonespeaker dead
2. Stereo speakers work under certain conditions
3. Wired headset that came with the phone works, both for calling and media
So it seems like a hardware problem. Please note, although I downgraded the phone to original, official Swedish Qtek 9100 ROM, it has been thoroughly tweaked and upgraded to a number of different WM6 ROMs - but all that has been working beatifully!
Still, what are the odds for the mic&speaker dying twice in a row, on different phones (i think the present one is a replacement)?!?
Question: Does anyone recognize this? Is there a possibility that it is software related, and maybe fixable? I have searched both the web and these forums but haven't really found any information on it.
ANY input would be greatly appreciated!
Additional information:
Qtek 9100 (Swedish), G3 model, WM6 upgrade successful (unlocked)
EDIT: There are no system sounds, which is wierd, because the phone can still ring. I thought the system sounds came from the stereo speakers on the sides of the device?
Hello all!
It is a glorious day to be alive!!! Or to have a fully functional Wizard, at least!
Lol - my topic isn't very old, and i reply to it myself with a solution (?). I Googled after the Wizard service manual, and found it right here on Xda .
In all honesty, i didn't do all that much. I just followed the disassembly instructions of the wizard about half-way through, to the point where you get down to the back of the motherboard. I poked and fiddled enough to locate the mic assembly, only to discover that the mic is soldered to the mainboard of the phone. So, i figured i'd just leave it be, because if the mic is really broken the motherboard needs to be repleaced, or a replacement mic needs to be soldered on there.
After removing A LOT of dust in there (honestly, i think the service center that had my device last time wasn't very careful with anything, even a screw was missing! ), i reassembled it. The flat cable running to the keyboard was also a little skewed, but that may have been me, anyway i corrected it too. Same with the speakers.
Long story short, after successfully reassmbling the phone, i fired it up, called my home phone and voila! I works!
Not much of a fix, as i don't really know what i did exactly, but dust, dirt and some bad connections/soldering may have benn the culprit.
All in all, i'm very pleased with my afternoon here. Thanks for stopping by .

hi epatnor,
I think the problem with your phone was a stucked microswitch in the 2,5 mm connector for the headset. I read about it here in the forum. Sometimes the switch stays in the closed position and the phone still thinks the headset is connected. Thats why all the sound is sent to the not connected headset and therefor your phone seems to be not working (unless you connect the headset)...
But removing the dust is for sure not a bad thing...
For the next time: I think there was an easier solution for this problem than disassembling your phone...
regards
huibuh_1
Thanks huibuh_1,
Yes this was probably not the smoothest way of "fixing" it. That said, the stucked microswitch theory would actually fit my problem well - I can see now that the exact problem I was having would arise if such a switch was indeed stuck.
However, I think that the problem would be more intermittent since I actually use that port now and then - especially since it's the only way to talk (besides using a bluetooth headset that is). And since I connect the wired headset now and again the switch is used and moved, I suspect that this would result in the speaker/mic coming online again maybe..? Temporarily at least?
All the same, thanks for replying - this might happen again and with your information I'm better prepared for it!

My HD2 Vibration Not Working Any More...

Today I noticed that my HD2 vibrates strangely, it sounds like a shaving machine when vibrating
I performed many soft resets, hard reset, then I flashed an offcial ROM, SPL, etc. but nothing works. I guess the problem is related with the vibration hardware.
I will be sending my phone to HTC service tomorrow, and let you know about the results.
Anybody faced the problem? Or any suggestion before sending the device to service?
Thanks...

I remember (2months ago) that my vibrate works strangely, i hard reset and it works again perfectly!
There was some issue posted a few times where the camera flash was pressed in, and was interfering with the vibration somehow.

I think I have the same problem, my camera flash seems to be pressed in (one side of it).
Is there an easy solution or should I hand it to the service?
Thanks...

I am trying to find the older posts you mention, but no luck so far. Can you post the links to those post, I might be searching with the wrong keywords or something like that...
Thanks...
Vibration seems to be a big problem. I had the same issue. only solution: warranty repair. my phone was replaced by 02.

Can't seem to find them... anyway, the flash housing is nearly directly over the vibration motor thing, and if the plastic flash cover gets loose it could very well push the flash housing down (it's not very secure, pretty soft metal actually) and block the motor.
Just check if the plastic flash cover is pushed in from the rest of the body.
E: If it is, then get it repaired by warranty, as it's not worth opening it up to fix yourself and voiding your warranty.

This is exactly what happened to my phone. The lower part of the plastic flash cover looks pushed in (I checked with another working HD2).
And yes, I handed the phone to the service today. I hope they do not break other things when trying to fix this issue
Thanks...
Vibration lost

Hi,
My Leo stopped vibrating. I saw your posts and checked the camera flash. It was indeed pushed in. My warranty was not valid, so I tried to fix it myself. It was actually very easy. I followed a video showing how to disassemble the Leo . As soon as the housing is removed, we have access to the flash plastic cover. I've just snapped it in very carefully et voilá: the phone is back to its own self!
Many thanks for the tip. I would never have guessed it was related to the flash cover!!

I am glad you fixed your problem easily.
My phone is still not back from the service
I have my phone back...
Finally, I have my phone back. The service report tells me that they have changed a part responsible for vibration. I checked the vibration functionality and actually it is working fine now. One surprise however is that the flash cover still appears to be pushed in.
Same problem
My TMobileUS HD2 is having the exact same problem - no vibration at all, even after hard reset. I also see the camera light's assembly is no longer correctly positioned in the body as it should be. It seems that the lower end is pulling into the body of the phone.
I treat my phone very gently, so I'm sure this didn't happen from rough treatment. Given that it's happening on a number of contiinents, this looks like a design defect.
TMobile demanded that I send it in for warranty service.
No Vibration Either
I have a TMOUS HD2, and I may have been the cause of this happening after reading this. I have no clue what you're talking about, but I have dropped the phone a few times and though the problem didn't happen right after a drop, it was just odd how it started. I had it set to vibrate when I pressed any keys, and then I was texting and it stopped. So... the only thing that I've seen that is a case that I only seem to have, my phone vibrates AT WILL, but when it does, it's very raspy and sounds very 'sick' and loud. So, I am not about to open my phone. I'm tech savvy enough, but in no way have I ever tinkered with hardware. I got my HD2 back in May, so I'm hoping that I have a warenty through HTC at least. I haven't contacted anyone about this, so is it my best bet to just send it to HTC or contact T-Mobile? And I have insurance, but I purchased my phone from Walmart. lol. Help?
I just came across this thread....
my vibrate function has been broken for several months and I've been delaying sending in for repair because I'm afraid of how long it will take (plus, it is the Australian version so I dont know if HTC North American will actually repair it under the current warranty)
I noticed that the bottom part of my flash does in fact seem to be pushed in. I'm considering doing what Maria did (opening it herself and popping the flash back into place). Does anyone have a sense of how long the repair takes from HTC?
Thanks
VIBRATION and FLASH PROBLEM
i'm having the same problem... lower part of the flash is pushed in. and vibration sometimes functioning sometimes not... but worst my FLASH NOT WORKING AT ALL...
Now having the same problem. This is a design flaw if I've ever seen one.
Same problem here, vibration was not working, but I just fix it!
I bought this T-Mobile HTC HD2 off eBay, and turns out that the vibration was not working!!
Once I found out this thread and the information about how the flash cover was blocking the vibration motor from functioning, I was able to confirm this was exactly what was happening!
So, I decided to open up the phone. I did not had to extract the entire screen piece out, I just had to unscrew the four screws and use a "shower suction thingy" on the screen to help pull it out but just the top part (in other words, half way out), because I only needed access to where the flash cover was, and then I was able to use a thin screw driver to PUSH back the flash cover to it right position. Then, after putting everything back to its place, the vibrator motor started to work!!!
Maybe I will put some "super glue" on the flash plastic cover to secure from being accidentally being push in in the future. Anyways, thank you everyone here on the forum for sharing your ideas!
As a late follow-up to mine... I called HTC and got an RMA number. Put off mailing it in for 3 weeks while I backed it up and arranged a temporary phone.
Mailed it on a Friday. Had it back with a replaced back on Monday.
I was EXTREMELY happy with the customer service on this one!
Missed 3 calls today... realize phone is not vibrating. Check different things that should make phone vibrate... nothing...
Flash lens is not pushed in this time... I'm about a month out of warranty now. Wonder how this is going to go over
I had this exact problem occur a few days ago, and I opened it up and simply snapped the light cover back into place carefully. But my phone still wasn't vibrating, so I opened it up again and I saw that the black rubber around the vibrate motor was causing the part that creates the vibration to get stuck. I simply just snipped a bit away so that the it was free and ta da! However the vibration is still weak compared to before so I don't know how to fix that? hope this helps you, and if someone knows why the vibration might be weaker than before the problem started any help would be great. thanks

Replaced screen and...

Hello Everyone
I have an Acer S200 and I ended up cracking the digitizer and lost the use of the entire display. Not sure how. It was in my pocket.
I purchased a replacement on ebay and replaced it. The screen works just as new. How ever I seem to have done something to the earpiece and mic.
When making a call, the earpiece is silent and the no one can hear me. However if I turn the speaker phone on I can have a complete 2 way conversation.
I originally thought it was my ROM however I have tried a few and finally placed the official one on, no luck.
I have taken the phone apart and put it back together a couple times, making sure that all peices are tight.
I am at a loss
Any suggestions will be appreciated
Thanks
Solved
I was able to solve this issue. It was prevoiusly posted. I did search however I was entering the wrong perameters. Anyways...
The solution is here...
Was not able to post URL...
You can do a search for "Speaker problem"

Recently Water Damaged, now booting - but microphone not working.

Recently my Nexus 6P got some water damage from a canoe trip (even though it was in a water "resistant" pelican case), and was not booting up. Took it to get repaired and the shop cleaned up the corrosion on the bottom of the phone where they said the water damage was. Phone booted up perfectly and everything was working great - wifi, gps, speakers, vibration motor, etc.
A few moments later my wife called me and I answered only to realize that she could not hear anything from my end. The microphone was not working. Took the phone back and they replaced the bottom PCB (daughterboard) of the phone which holds one of the main microphones.
No luck. Now I'm able to use my Nexus 6P for EVERYTHING except making phone calls, which kinda blows. I know I could use bluetooth etc. but that's not really a solution for me.
Does XDA community have any thoughts / ideas about what the problem could be and any possible solutions for me?
Thanks a ton guys!
Nathan
I think your only option is to take it back to the repair shop again.
Shop said that is all they could do for me. The daughterboard is brand new, so if the microphone is still not working, could it be something wrong with the connection to the main board? Would replacing the ribbon cable prove useful?
Thoughts appreciated!
Nathan
Without seeing the device it's very hard to say, but yeah, possibly.
I'm having the similar issue where I went to a foam paarty and got the phone wet. Fortunately everything is working fine except the proximity sensor. Sent phone to Ubreakifix for repair but tjeu couldn't find the part anywhere. Huawei/Google don't provide the replacement part & Huawei don't repair water damaged phone.
If someone could tell me where can I find the Proximity Sensor replacement will be very much appreciated.
Thanks

Help ! Water damage . audio wont work

Hey guys I'm new here. A few weeks ago i happened to not notice that some liquid spilt on my phone while driving and i left it there like that for a while . then When i got a call and answered couldn't hear the other person. Then i noticed water on the fingerprint scanner as i had a spigen case and it had managed to get into my phone. I turned off my phone immediately and disconnected everything. Next morning i happened to removed the board and dry it out as i have done this many times before when i changed the thermal paste. The water damage indicator was red. After ensuring everything had dried out i put it back together and my phone powered back on and it charges well. But when i go to play an audio file. I get an error Sorry, the player does not support this type of audio file. The audio recorder hangs and i camera app also works but when i switch to video it hangs. Phone has been reset to factory. Same issue. Sorry for the long story. Need some Help on what part to replace. Is it the mic and speaker that's busted or some component like the DAC. If so where is the Dac located and how can i go about fixing this. Any part websites you recommend I'm from India.
Any help is nice guys. Please
My first V20 was one I bought on ebay that had sound not working. Also the camera was not working. I though it would be an easy fix, well, hoped actually, but it was not. I didn't pay much for it so I though it was worth the risk. The problem you have sounds exactly the same. Software reset won't fix it.
I did get it to work though temporarily. I put the motherboard in the oven for 10 minutes. It worked for a few days only.
The problem is that the DAC chip is now faulty due to water damage I'd say. You need a new motherboard. I would suggest buying a new v20 and keep the old one for charging your spare battery on quick charge! Or you can buy a new motherboard only on alliexpress for about 50/60 euros.
Thank you. I did consider an industrial oven. Could you please help me with temps you used? Was it the same error you got while trying to play a track?
