Tried to replace USB port, broke motherboard connection

I have Samsung a Galaxy Tab S 10.5" with a bad USB port (was flaky, then stopped charging altogether). I ordered the part and tried to replace it myself. Sadly, I managed to break the little tab that fastens the ribbon cable onto the motherboard (rookie mistake). So now there's nothing to hold the ribbon cable to the board. If I plug the tablet into my PC and press my finger on the ribbon against the motherboard connector , I get intermittent connection. So it could be working but obviously not viable way to go.

Can this be fixed without replacing the mobo? Will a little soldering do? I don't have a solder or any soldering experience. I may have to take it to a local shop. I would like advice either way so I don't get robbed by repair guy. Thanks in advance

Do you think you can repair it? thanks

dearbart sounds like you broke the connector itself. Post some images of your damaged connector etc. with your question. Use this guide for that. That way we can see what you see and possibly find a replacement connector. Most likely you will have to get it soldered. Once you have the part and you take the logic board to someone with some microsoldering experience, the cost should be minimal but it will depend on who does it. You should always consider the cost for the repair should not exceed the cost for a replacement board etc.

Update (01/06/2016)

dearbart, the broken connector is Samsung part number 3708-003187 and it is readily available. Cost will vary depending on your geographic location, with ~$15USD being the average. Now it will only be a matter of finding someone to solder that part for you.

sorry, I should've done that before. images added per request.


Where can I order this part? I just did the same thing and was wondering if you got the part? Did you get someone to fix it for a reasonable price? Thank you, Regina


Same here! I was replacing the battery and was a little too rough on the motherboard connector of the charging port when removing old battery! Is it an easy repair job for a local phone shop
