Dear Friend,
I had the same problem. The connector you need is from Molex.
Excatcly the same is not possible to buy, because was made just for Apple LG.
I find by Molex the connector has this part number 53780-0670. I purchase it from Mouser electronics under 2€.
I think is the same, just not black but white.
You can replace it or someone who can fine solder. Yo save a lot of money, believe me!
I hope I can help you with this information.
Let me know.
Bye Bye
