I have changed my defect display and my right coax connector is broken .
What is the function of this connector / cable
There is a second connector could I use this connector
If you broke the PCB Connector, you need to get to a proper repair shop and have it replaced, if it had a cable and you broke that you need to get it and have them make you a new one. But since it's a phone I would guess it's the PCB antenna. Also those are the antennas for the GSM combo module, WiFI/Bluetooth combo, so you will either have reduced or no signal from your operator or you won't be able to connect to WiFi/Bluetooth reliably or at all.

Anyone have a broken XT720 they are willing to part out or maybe already started to part out?
I replaced my digitizer glass today (boy was getting the glass removed a pain in the ass!) and when I was reassembling the phone the white antenna cable end broke off that pushes down onto the mainboard.
You can see the cable at the 5m mark in this disassembly video (not mine):

(The video is good but unfortunately stops before taking out the digitizer glass)
I initially thought this may be for wifi antenna (same antenna cable found in laptops on wifi card) but I still have good wifi signal, but I am unable to register on network so it may be going to cell radio and not wifi radio.
I may try and make one out of an old laptop cable, but I would have to cut it/solder it to get the right length (and thats if the connector is the same), so I am hoping someone is willing to part with one!
Thanks!
Look around
Alright; so the connector where you plug in the ribbon cable for the mic, the white fastener that
acts like a breaker decided to fly off so my mic doesnt work. If I put solder in the area where the
fastener was; will that make the connection work and therego make my mic work again? I really
don't want to buy a new mobo, I just bought a new lcd and digitizer...... response asap would be
greatly appreciated!

Not unless you can solder the individual cores of the ribbon cable back onto the right place on the motherboard, no.
I am hoping to salvage my wonderful nexus 5. When replacing the screen I partial pulled the 3g antenna connector off of the main board. Now I randomly have service. Sometimes pushing on the back of the phone works to reestablish service, normally it does not. I was curious If I could get a custom antenna wire that would go from what i believe is the antenna test point to the normal connector on the bottom. If you think this would work any suggestions on where I could get that type of connector made
Hello,
So I have the following Samsung Multimedia Dock, which was working fine since a year or more. It was used pretty much regularly with Galaxy SIV (either with stock or extended battery ). I guess after prolong usage and atmosphere condition the solder point on the micro USB connector internally got dry and got detached. Hence it stopped working.
Hence when opening it to have a look inside, I lost the sequence of 8 wires connected to the micro USB connector on both sides (4 on each side). The pins on the micro USB connector are marked numerically 1-8 , however I cannot see the same number on the main PCB, so I am at a loss to understand how to get them solded again , in which order and sequence.
It is I guess a 11 pin micro USB connector because the dock had HDMI, Audio Out, and USB in (OTG) connections and power charging all at the same time.
Case cracked open and the main PCB and micro USB connector are apart.
Close up of the PCB
PCB and microUSB
MicroUSB connector call it side A (4 small pin out number from 1-4)
MicroUSB connector call it side B (4 small pin out number from 5-8) (I was able to see which wires were connected on this side so I marked this side with a blue marker and did the same with the 4 wires loosely held on this side after detachment)
PCB wires close up. Total eight wires. Starting from right the order is Black->Yellow->Green->Red->Yellow->Black->Red->Green, each of the wire needs to go to a pin 1-8 on the micro USB connector.
I know there are no published schematics for this PCB and 11 pin Samsung connector, however I am relying on the electronic expertise of the gurus around to help and guide me.
Thanks for your guidance.
Hello good people of xda. While I was disconnecting the gsm antenna wire I damaged the ever so freaking delicate connector so I obtained a new one and fitted it but.. Still no data signal. I noticed on the motherboard that there are two connection points that connect with the rear cover.
One appears to be damaged. Do these contacts have anything to do with gsm antenna.
I wonder if there are any other points on the motherboard that I can connect the wire to?
