Ribbon cable for the earpiece!? Possibly, but check the manuals on Link removed - no longer valid
I wrote a piece a while back for the TyTn (not the same phone I know, but similar). Have a read here:

Now that front speaker directly contacts the m/board and the spring contacts can bend a little. Easy to fix if you are happy to dismantle.
Mike

thanks
the phone was closed when it fell so not sure on if it is the ribbion cable. also r u sure that the speaker is atached using the spring contacts, because i have the tools and the abiltity to take it apart just dont want to void my waranty if i still have on i have had it for more than 2 years.

I agree, if you have a warranty then use it.
If not, then I am puzzled about this earpiece ribbon cable. There are ribbon cables of course but not to my knowledge one for the earpiece. Can you post a link to the item on ebay?

i believe my phone is out of warranty but i might be able to reason with the people at the store. but if it is just reseating the contacts that is not hard fro me to do myself

i found this i think it is the cable listed on page 17. but as rthis is rather expensive i would rather be sure before i purchase

Agh I see what they're referring to now. The flex cable connecting the top daughter board. No - I do not believe it's the flex cable because that would likely mean the top buttons would not work either. Even if it is, the cable, it would just be a matter of re-seating it's push on connector.
In the picture the speaker is the darker object on the left side.
It looks an almost identical setup to the TyTn link I gave above.
Unfortunately it's a fairly major strip down, not just a case of popping off the back casing. The TyTn Service Manual would be helpful. Very occassionally the earpiece speaker is broken (rare - it's normally just the spring contacts), but there is a Motorola equivalent that will fit if you needed one. (The OEM speaker is not easy to source).

thank you both of my upper buttons works so im gusing it it not the borad. do you think that it is that much of a tear down because i have taken apart many apaches xv/ppc6700's and it was not that much work. also to reseat the contacts i just push on the speaker.

If you have some experience dismantling then it should be ok. The flex cable between the two halves of the phone may have some sticky tape holding the connector in place - that is a little bit fiddly, but not difficult.
To make the speaker make better contact with the board, you need to bend out the gold colored contacts just a little. (When the phone gets a knock / fall it can bend the spring contacts in and so it no longer makes contact with the board) The pics on here for the FRONT speaker show the contacts I'm speaking about. http://forum.xda-developers.com/show...27&postcount=5

ok so the speaker is just sitting on the board or is it held done by anything.

It is between the casing and the board. Normally the springy contacts make this a firm contact. After a knock the contacts get a little bent and it then rattles about and does not press on the board.
It is NOT soldered on, just pressed against the board (normally)

wow. I have buy a second hand device and I have the same problem. For sure my screen was changed. I have open the phone from the video here:

Antena it's in up-left when you watch on phone.

I am almost sure at the left side directly under the volume button .

It won't be in the upper portion of the phone, as this increases the strength of the radation the head is exposed to. I believe there is a law prohibiting it from being too near to the skull. Which is why all antennas in modern phones are internal and not placed by the speaker at the top of the phone.
Although this seems to not apply to GPS, Bluetooth and Wi-Fi, which is what those wires by the speaker at the top of the phone are.
Class 1 Bluetooth devices can cause exposure to radiation similar to that emitted by a cell phone if they are operated in the immediate vicinity of
the body. Bluetooth devices are designed to limit the radiation power exactly to that actually required. When the
receiving device indicates that it is a few meters away, the transmitter immediately modifies its signal strength to
suit the exact range, which reduces the total emitted radiation and signal interference (IT'IS 2005).
A study commissioned by the Swiss Federal Office of Public Health (FOPH) measured SAR for several Bluetooth
devices, including two different class 3 hands-free cell phone headsets. The headsets tested had SAR values of
0.001 and 0.003 W/kg, which is 34 and 12 times lower than the SAR of the lowest-emission cell phone currently
available (Swiss Federal Office of Public Health 2009a).
The article can be found here.

The cell antenna is the strip on the bottom below the battery door,the wifi antenna is at the top right (if looking at it with the screen up),and the gps antenna is at the top left. There is a white cable that is supposed to run from the gps antenna to the bottom side of the main board,and a black shorter antenna cable that is for wifi that plugs into the top part of the board. I have a pretty strong feeling that the person that fixed your phones (whether that was you or someone else) probably didn't plug that cable in the right way.
<EDIT> By the way,if either of you want one that works the right way/for parts,I have one for sale that the volume buttons don't work and the lcd is cracked,but everything works other than the volume buttons.

Anyone ever have any antenna issues without taking apart the phone? my phone just developed issues with dropping wifi unless im close to the router, im guessing an antenna cable is loose. and for those who have fixed the antenna issue, how hard was it?

according to the HD2 manual, the antenna is the bottom 1/5 of the phone

The WiFi antenna is located at the right of the camera watching the camera in the back panel. If you watch this video, http://pockethacks.com/category/service-manuals/, you will see that the Bluetooth/Wireless atennas are located together and connected to the main board with a coaxial cable.

What this guy said +1

I find myself in a similar situation to nedko76. I had to take my phone apart but just the case away from the screen circuit boards etc because the plastic led shield had come lose and was touching the vibration device causing a strange noise.
So i managed to get the phone apart (which was not as easy as shown in the video) i didn't touch the screen part at all, put it back together again and switched it on. To my relief it switched on, all looked good, the noise had gone from the vibrator however the only thing that is not working is the wifi.
I'm hoping someone has resolved a similar issue without the need to reopen the phone again as i can't help but think i will do this and see nothing wrong. Which would either mean i've somehow damaged the wifi circuit board or something else.
I use wifi alot and will miss it loads if i can't find a way to fix it.

As already mentioned, WiFi antenna seems to be feeded by a tiny cable, it is probably using some tiny coaxial connectors, those are usually relatively easy to accidentally disconnect. I would start from looking at those and making sure they are "wedged in" properly.

I have taken the phone back apart and checked all wires are pushed in and everything is connected from what i can see. But still nothing.
Wifi switches on but just stays at scanning. Now does that mean that the wifi is working but the antenna is the issue.
I'm just wondering if its a software issue somehow. As i never touched any part of the board, or antenna etc whilst it was apart and like i've said i couldnt see anything out of place or loose.

Dude,
There are 2 brass clips on the top right of the motherboard which attach to the rear case antenna. Make sure these brass clips are correctly functioning and working. There are 2 for the gps at top left big ones from memory then there are 2 at bottom for radio antenna and two at top right for wifi.
Make sure these are all ok...
If you can post a detailed photo(s) I can give you more assistance. Zoom in the motherboard and the clips if you do provide pictures.
Good luck

Yeah i saw these when i took the case back off yesterday, i looked at all them to see if there were any differances, any broken off etc but they all looked fine. I did lift the ones for the wifi and bluetooth just a little bit to make sure when the case went back on they would be in contact. But still no luck.
I find it difficult to believe that just taking the case off pushing a little bit flashlight plastic back into place would really stop the wifi/bluetooth from working.
I'll have to keep searching the web to see if anyone has resolved the same issue and what it actually is. It would be interesting to see if people take their cases off then just put them back on again if they have the same issue or whether somehow i've messed something up.

Dude, show me a pic of motherboard to see if all your connections coaxial are ok.
Otherwise, your hardware maybe fubar. I have opened mine several times and no probs.

Right I took my phone apart again this morning to double check everything. I noticed the cable attached at the bottom as mentioned in previous post. It lifted off a bit too easily, so I positioned it correctly and pushed it back down, my WiFi now works. So that was my issue.
So my advice would be if both your Bluetooth and WiFi do not work, it is more than likely the cable is lose. (more likely if your phone has been a part obviously)
Thanks for everyone's help and advice on here. no fubar hardware here thankfully

I'm also experiencing this after changing a smashed screen... The accident it self did hardly cause this since I used the phone with full performance for about a week between dropping it on the ground and draging my sorry ass to the retailer. Since I don't intend to open this stuff up I guess I'll have to go back there. I will refer to this site if they try to indicate that their sloppy disassembling isn't the reason... Please, feel free to boost me with more cases like this...

I have replaced the screen myself and have the same problem with Wi-Fi only.
I dont know why Wi-Fi run only without the battery cover.
I' m trying to torque chassis for looking if it is a mechanical issue but it seem not.
I've tried also to connect the two little contact they are at the same level with the bottom of the battery looking the phone from its back without the cover.
I've not found yet any relevancy with the presence or not of the back cover related with Wi-Fi transmission.
I remember that when the phone was disassembled, I have slighty lifted with my finger the bigger one of the two lamellar contact of Wi-Fi antenna; anyone know if this could be the cause? Must to touch these contacts chassis or not ?

nothing else ?

Low signal strength

I just recently sent my phone to the shop so they can fix the digitizer, it broke on my pocket when I sat on it. After that the signal strength has gone drastically low, can this be a hardware malfunction or VPN issue? Thanks for the help

have you tried to update radio? its a good place to start. what are your system specs? what rom are you running. there no such thing as to much info when asking questions my friend.

I did not understand if your problem has appeared after the replacement of the touch ..
still looks like a hardware problem, the black coaxial cable that goes inside the black volume button may be loose (almost certainly) his fixation on a snap ring of 1.5 mm.
regards

I think you have broken (or lost connection) one of the four connectors which rely on the casing (which is the antenna on the plastic case)... see picture http://img862.imageshack.us/img862/9258/htchd2disassembled5.png

Poor Blutooth Signal

Last week I replaced my flex ribbon cable because I tore the ribbon cable to the power button while replacing the digitizer.
After installing the new flex cable my blutooth signal has been terrible. When listening to music via S9-HD's when I go to put the phone back in my pocket the audio cuts out just in the motion from texting to placing the phone in my pocket. Also when walking its impossible to listen to any music because it cuts out so much.
What might my problem be? Is the blutooth antenna on the flex cable or did I mess something up when I took apart my phone?

anyone?
bump

We aren't ignoring you dude. I promise. Have you disassembled the phone again and tried wiggling things around?

Finally had the time to take it apart again and wiggled things around. It improved a little bit, but still the range is no where near what it was before I replaced the flex ribbon cable.
Does anyone know which cable is the Bluetooth cable? is it the black one on the left near the white cable or the single black cable on the opposite side? I did notice when I took my phone apart again was a small pinch in the single black cable. Would that pinch be enough to break the wire under the shielding?
I can get pics if needed some time this weekend.

Those types of cables are made of SUPER fine wire. A pinch can easily sever them inside the shielding.

How do i know for sure that the kinked cable is the bluetooth cable? So I can order the right one to eliminate that factor.

Does it look like that?
http://www.cellulardr.com/t-mobile-...y-touch-4g-blue-tooth-coax-cable-tmobile.html

There are two that look like that.
One on the left side and one on the right when looking at the phone with the back open and the screen facing down.
Sent from my Glacier using XDA

Well, there is a white and a black cable. The one in the product photo is black. Provided that is not a generic stock photo it should be the black one.

[Q] Phone damage - GPS

Just looking for some info that I Can't find doing searches.
My note 3 was thrown at a wall. The main impact was the upper right corner, near the front facing camera. The frame was bent and the front screen was shattered entirely. The screen did not even light up at all when turned on.
I've had the front screen / case replaced. The phone now looks as good as new but the following two things do not work:
- front camera (it works but its blurred. Repair guy said it was shattered)
- GPS (cannot get a lock at all, not even sure if its being detected or what)
I have a new front camera coming in the mail (less than $10), but where is the GPS? I know it's located around the impact area, but what are my options / what could it be? The repair shop said the board looks ok, but I only found out the GPS wasn't working when I was trying to use navigation on the way home.
Can I replace the GPS antenna? If so what is the part called as I cannot find it anywhere.
I am hoping that the repair shop didn't seat a ribbon cable or something but I know this is probably unlikely and that the GPS is broke. If this is the case, what can I do to fix it?
Thanks,
