[Q] Nexus 7 - Very Flaky Headphone Jack - Nexus 7 (2013) Q&A

For the past few months, the headphone jack has gotten more and more flaky, to the point that I have to press down on the jack to receive sound. Does anyone know of a DIY fix? Its not the headphones themselves, as it has this problem with every pair I've tried.

I've had it happen with another Asus model. The solder cracked and the tiny traces broke, resulting in bad connections. What you can do is check continuity between the jack and the circuit. Tedious work, but if you're game, you need a 3.5 mm jack with exposed wires. Trace those wires to the connecting points on the motherboard.
If everything is good, then 2 possibilities: (1) the connecting points inside the female jack (soldered to the motherboard) are worn, causing intermittent contact, in which case you need to replace it. If you can't find one, let me know.
(2) If the problem persists, but varies depending on how much pressure you put on the headphones jack, then maybe it's just dirty. Best is to use high-grade alcohol (91% or more) and clean the inside with a q-tip with less cotton; plus use a toothpick with double-sided tape at one end and swirl inside the female jack to remove impurities and dirt. Good luck.

Thanks. I had a feeling it might just be dirty, but I wanted to know if anyone had any alternative solutions if that didn't work.

speaker not working

my phone speaker has stopped working, can only use on speaker phone. Any ideas or know where i can get spare parts.
i really dont see htc getting spacial custom speakers made for their phones it would be too expensive and there really would be no reason to
so if i were you i would

take apart my device
and get the part nr from the speaker or simply remove the speaker
and take it to a electronic store and get one like it
The speaker on my mini s stopped working shortly after using headphones in the headphone socket.
I googled the problem and read somewhere (can't remember where) that a solution might be to "blow" into the earphone socket.
They couldn't be serious, could they??? So I blew, and blow me, it works ok again. Maybe muck gets into the socket. As I say, it worked for me.
Headset connector causing issues with internal speaker..
Before you start pulling apart your unit (and voiding any warranty left), make sure to try a bit of Electrolube contact cleaner into the headset connector (and a few insert / removes of the headphones).. The little metal ground pin seems to deform and lock 'out' sometimes.. causing the PDA to get stuck in 'headset inserted' mode...
Unfortunately the only way to fix this if the connector is bent is often to bend the connector back into place (open the unit).
Good luck!

External wifi antenna

Hello,
i want to connect external wifi antenna to S620 and i need some small help with that.
I dismantled the phone and removed shields from all ICs.
On picture 2 and 3 are Texas Instruments WiFi chips.
On picture 1 is other side of the board, with some metal piece and connector, which might be external wifi connector.
The connector is at opposite side in left bottom corner if you look at image 2, between PASS sticker and mounting hole, at the corner of large PCB ground pole.
Is that metal piece integrated antenna?
That connector is probably not U.FL.
Anyone know what type of connector is that?
Thanks.
Not sure but follow the link below for the service manual, it may give you some insight:
http://forum.xda-developers.com/showthread.php?t=402998&highlight=service+manual
if you managed tu connect it, let us know everything...
hope you can do it succesfully!!!
Ok, so i looked at the service manual, the connector is diagnostic (RF measurement) type, with switch.
MM8430-2600RA1
Probably will be in all HTC devices. So i will try to search on the forum, if anybody done this on different phone.
See page 9 and 10 for switch schematics and pinout
http://www.murata.com/catalog/o30e8.pdf
There are "probe" cables for it, but the probe connector is too big to hide under the cover.
I have a friend with experience with SMD, so i asked him if he can desolder it and solder pigtail with RSMA.
Cable can be taken out of the phone by using free space around hole which covers the GSM antenna connector.
I verified that by putting the cable in and closing the phone.
I also tried to hold stripped cable on the connector, with attached directional antenna and i picked up the APs in that direction, so it is working. (and really well)
The problem is that ground poles of the connector maybe connects ground to the power button, so after desoldering, it might not be possible to turn it on...
The safe way can be removing that piece of metal (yes, it is wifi antenna) and solder pigtail instead of it.
It should be simple, because under it are only two "paths" in PCB.
However, the best way is probably to solder it on opposite side, there is a PCB path from Wifi chips, going through the PCB, ending on middle pin of the connector.
But that cannot be done, because there is no way how to get the cable out of the phone.
I still prefer desoldering the connector, because it is placed "before" the antenna, so connecting it there would give a bit better results.
Edit: i searched the forum a bit, but all i found is service manual for Diamond, which seems to have U.FL connector. But i will not buy it because of that, only maybe when it will cost 80 USD like S620.

Fix Sennheiser HD205

I was handed down a pair of Sennheiser HD205 headphones. I had used them a few times before and they sound awesome! However, since I got them they make my music sound weird. For example, sometimes it turns every song into an instrumental version or it is really soft and will get really loud if you jiggle the cord right.
I cut off the jack and found 4 wires inside. 2 copper wires, 1 copper wire painted blue and another copper wire painted red. I removed the paint using acetone nail polish remover and fine sandpaper. Now that I have the exposed wires, I connected them in a new 3.5mm jack from radio shack. I think the colored wires are + and the unpainted copper wires are -. Note these wires are actually bunches of wires with tiny radiuses.
Sadly, when I connect the wires in I still have the distortion problems. It mostly has to do with losing the vocals. If I move the balance on my computer to all right or all left it will sound perfect. If I also connect the former red bundle to the ground of the 3.5mm and the former blue to either the L or R I can get mono.
I am thinking of cutting the wire higher and repeating the acetone procedure and rewiring again. Will that work because I don't want to keep cutting and cutting and eventually cut the whole wire to small pieces!
Your help is greatly needed and most appreciated. I really think these headphones will complement the voodoo sound on my I9000 nicely
187 views and nobody has any idea?? or needs more information for a fix recommendation??
Balancing audio?
I know this is probably a bit late. But i had a similar problem. My Sennheiser HD205 Headphones Started acting weird. They have an excellent sound of them and are really comfortable for someone like me who would wear them for a long period of time. Recently I had to get the cable fixed that went into the actual headphones because if they moved ever so slighty all sound was gone. I got them fixed and then the sound went weird the next day, when ever I played a song with a heavy bass, once the bass part came on the whole song was muted until it stopped and the vocals were distorted, then I was playing around with the sound settings on my computer and i noticed the audio balance was a bit off then usual (Left=78 and Right=78) so I brought them back down to 50:50 and it was all better . I thought maybe you should try that, seeing as nobody else left a suggestion! (If you dont know where to find the sound setting on your comp, go to: Control Panel>Hardware and Sound>Sound, and a window should pop up. right click on the speaker output you use (its called Speaker by default) and click properties then click on the tab properties and balance it to 50% on both sides) NOTE: Make shure your not playing any music (eg. Itunes) while your doing this. it MAY stop the program from working! Good Luck!

Hello,
I had the same problem. Unlike most headphones, the Sennheiser HD205 uses two separate ground wires, these are the two uncolored wires. The red one is for the right (the pin that's closer to the middle) the blue one is for the left (the pin that's further from the middle). The colorless wires both go to the ground pin.
I connected them this way, now I don't have any distortion, and I can hear the vocals loud and clear on both sides.
Sounds like you don't have ground connected to the signal source (jack).
If the jack has 3 connectors (tip + 2 sleeves) the wires go like this: tip - blue, first sleeve - red, second sleeve (furthest from the tip) - ground (usually golden).
Try an connect the two sides separately and check if they work individually. Only then connect them both. If the cable doesn't have any shor circuits it should work just fine.
Good luck!

[Q] Fried Headphone Driver?

So I am having a weird issue with my headphone jack. I have replaced it to no avail.
One day it just started getting all static-y and then cut out in a period of 10 seconds or so. If I wiggle the headphone jack it will come back on. However, without even touching the device, it cuts back out sometimes.
I have tried flashing different ROMS so I know its not software related.
I had not played with any audio software that boosts gain that could have damaged it that way.
As I previously stated, I ordered a replacement jack and replaced it, making sure the ZIF connector is snug and making contact.
It does it with anything plugged into my headphone jack, any pair of headphones, any stereo with a 3.5mm to RCA cable, anything.
Has anyone experienced this? I have a feeling whatever circuitry that drives the headphone jack itself is damaged.
Audio is always fine over the speaker or bluetooth.
Thanks in advance.

It's a common issue with these phones. I went through the same thing you did, ended up replacing the jack multiple times to no avail. Eventually just cashed in on my phone insurance and had them send me a new one. As far as I could find, no one was able to resolve the issue once it began happening, but it would gradually get worse.
Sorry to be the bearer of bad news, but I'd hate for you to chase your tail around as I did. Temporary fix is putting pressure from the front of the phone to the back in a pinch fashion about where the headphone jack is. Goodluck!
Try using a hair dryer on it for a few minutes (medium to no heat with a fast sweeping motion... not concentrating the air on it 100% of the time). There may be some moisture in the connection that might be messing with it (happened a few times with my portable devices and it helped all the time).

I have fixed tons of these on our phones. Common issue. That part is like 5 bucks the you need to replace. Taking the phone apart to do so, its pretty simple. on a scale of 1-10 10 being hardest i give it a 3. I can assure you wont void warranty because there's nothing to void, lol. If you need help advice or want me to do it for ya, send me a message.

What is the part you are referring too? I have already replaced The headphone jack and it did not fix it.
If you replaced the internal jack. Then 1 you ordered a defective one or 2 your main board is fried. If you bought the part from China its probably bad. Edit: did you actually replace the headphones yet?

I ordered it from a US seller. And yes the headphones were the first thing I replaced. The headphone circuitry must be fried. Oh well. Thanks for the help guys.
Did you clean the area with 99% alcohol?

Earphone jack keeps popping out?

Not sure if this is a problem with the particular earbuds I'm using or if this is a common problem. I've already when through cleaning the jack with q-tips and alcohol. I'm using the Sony Earbuds (20 buds). It seems the jack is easy to lose connection and then I have to push it back in with my hand. My fear is that eventually the port will just go bad or become loose.

I have had the same problem for 1.5 years. It has gotten progressively worse and now I just have to use bluetooth earbuds unless I want to hold the earbuds in all the time. I've not seen any fixes available. This must be a common build quality issue.

You are not the only one with this problem I've had 3 of the HTC desire 816 but there is a way to fix it the metal prongs on the inside start to lose there spring I found the best way to fix it is to open the phone remove the motherboard and inspect the jack and see if its the soder or the prongs on the inside hope this helps
Yes I have HTC Desire 816 and headphone plug does pop out. If you have acquired great condition HTC Desire 816, I recommend only using a headphone with a plug that firmly clicks into the jack, or get a small male to female 3.5mm 1/8 inch TRS (TRRS for microphone) adapter from a retailer near you.
