Pinout of WIFI Flex cable?
I'm looking for a pin out for the WIFI flex cable for this iPod. I have 3 or so that I think I could fix with this info.
Here is the story on it so far...
Bought 6 touches from ebay, all won't power on. First one I grab I plug in and boom it is charging and worked fine (lol). The rest was no luck. Checking voltages etc I noticed the batteries are all dead and when plugged in, very little voltage is going to them, something around 0.6 volts. I removed the batteries and I get similar readings.
One of them I was messing around with the WIFI flex cable and pulled it up a bit much, I saw it ripped the wires, so I just took it off the rest of the way. Tried to turn on via charger again with no battery and it powered the screen, but did the inf reboot loop on the apple. So I throw the battery in it. As soon as + and - are connected I see a small flash and notice about the 6th or 7th pin from the ear phone has a burn hole in it. I use the charger to wake the iPod up and it powers up fine. Did a restore and everything works fine for what is connected.
I messed around with another one with the burn mark already on it and ended up pulling the flex cable off it also. Same thing happened except it has a pass code lock. I took the 2nd one's WIFI flex cable and cut it down so all the pins were at the end of the cable. Then I scrapped off some of the plastic off the ribbon to expose the copper at the end. I cleaned/tinned the board and the ribbon and soldered it back on. Good news is... all the buttons work fine, powers up etc. Down side is, the touch screen does not pick up the touches. I have double checked my soldering and it appears good, I have the pins lined up perfect and I have touched up the solder to make sure it is all connecting.
So basically to get back to my question, I would really like to get a pin out of that connection so I know where everything goes to the board to check connections etc. It appears like that area of the connection is a direct connection to the battery's + and -.
Also if anyone has came across this in the past, please explain anything I'm missing to help solve this puzzle. I have a 2 or 3 more I have not touched yet due to this common problem.
Couple things to note with this, the power and ground on the wifi cable of these are picking up as shorted, I have yet to trace what is causing the short. When the cable is disconnected from the board, the power/ground is no longer shorted on the flex cable. But in either case, the positive and negative of the battery is never shorted.
Sorry for the long post, but I hope someone will know what is going on.
Thanks for the help!
Is this a good question?
