I have broken connector on my i-mate and main board circuits are damaged after break and i need to find circuits chematic to repair board connectivities or use cable as a jumper. :roll:
Does anyone knows where to buy the antenna connector cable for our device?
I have broken the cable when i was replacing my screen...
I took my TF700 apart last night as the digitizer was not working following a drop and assumed that a cable had come loose.
Anyway, made a mistake while doing it.
I could not disconnect the cables between the LCD and digitizer and the connectors.
I since realise that there is a small white bar that you flip up. I presume I have "broken" the connectors or something as the tablet works fine when plugged into HDMI, but I cannot use the digitizer and the screen does not come on.
Any suggestions? Most that I have found have suggested "throw away and buy again as spares too much", but wondered if anyone had a bright idea.
I have found why the digitizer was not working, there is corrosion over the SD card and around the top connector to the digitizer nearest the SD card slot. It looks like mositure/drip got into the slot and may have shorted something? I have cleaned off the surface debris as much as can.
Anyway this would not impact the LCD which still displayed (until connector concern.)
Following that, is anyone getting rid of their TF700 and would be interested in selling it at a sensible price?
Thanks
If you didn't pull that white bar off or break it, it could possibly be that you have not properly inserted the ribbon cable and fastened the connector. I would open it again and check this before I did anything else.
Most of them work like this:
Open it by pulling at each end of the white bar until it moves foward a little, then gently lift it to about 45 degeres and the cable slides out with a slight tug. Putting the cable back in is the reverse. That bar has to be loose and at about 45 degrees to get the cable back inside the connector. Make sure the end of the cable is in straight and close the connector. Cable should be tight and not come out if you gently tug it.
The OP here may be willing to sell a likely brick:

Thank you for the suggestions, I have tried that, but none of the 3 connectors (2 for digitizer, 1 for LCD) respond. I connected it to the HDMI, but cannot see the screen respondin to my finger (maybe that is broken also ha ha)
Is it more likely the connector, or cable is broken? I suspect connector pins to be honest. Abit small for me to see though.
Digitizer or Ribbon Cable or ZIF socket ??? How to tell ???

Greetings!
Just curious how this problem worked out? I too have a TF700 with a working screen but no digitizer. Some time back during my first battery replacement (another story) I tried (we ARE a curious species you know) to open the ZIF socket for the digitizer cable (has twin, gold ribbons) and accidentally flipped the wrong side... needless to say it did NOT flip open. The black plastic top of the socket broke off exposing a little of the ribbon. Everything still worked fine so I counted myself lucky and closed her up and all was good.
Unfortunately I'm never willing to leave sleeping dogs alone and I attempted to replace the 2nd dud battery with yet another one (don't ever trust those "Brand New" eBay batteries)! This time I must have accidentally pulled on a ribbon cable a bit too much. When I closed up the tablet I ended up with a tablet just like yours... everything works great... just not with my finger! I opened it up AGAIN... to replace the original battery... you never can tell you know... while I was in there I tried reseating the digitizer cables (both sockets)... no luck.
So... now what... I'm hearing that some folks had their digitizers fail after about a year anyway... mine is two years old... so my digitizer COULD have just failed... or it COULD have been my messing with the ribbons and/or ZIF connectors. How to tell ??? Is there ANYTHING one can do short of ordering a replacement ZIF socket PC board ($25 eBay) and / or ribbon? With a two year old device I'm reluctant to spend much on repair... ASUS wanted $184 to fix it... and buying an eBay digitizer or ZIF board on the blind chance that one or the other is the problem seems a bit risky.... to say nothing about the chance of mucking up the heat separation of the LCD/digitizer! What's a digital explorer to do???
The only thing I was unable to determine was where does the forked golden digitizer ribbon cable GO on the glass end. Does THAT end ever come loose? How does it attach to the digitizer? Anything I could "fix" on that end?
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.
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.
