Hello everyone,
I've got a bricked LG G4 H815 mainboard lying around. Recently, i've noticed that there are 5 empty connectors scattered across it

In the service manual they are referred to as RF connectors (Part number: EAG63772101, location number: SW1002,SW1005,SW1101,SW1102,SW1106).
Since they say "RF", it seems likely that they are Antenna connectors (?). Does anyone have an idea, what they are used for?
Thanks
For external antenna

Hi everyone,
I just bought an sprint GSIII logic board of ebay and it said working condition. I swapped the board into my phone and it won't boot then I take a closer look at the board turn out there is a missing IC with all the pad pull off. Look like they was trying to replace the chip with screw driver lol. Anyway does anyone know what the chip is? just curious Thank!
the missing IC is in the middle of the picture.

After countless of hours diagnosis and doing trial and error in order to rectify the faulty touchscreen issue where a certain part of the touchscreen area is not working. My solution for this problem is by putting a piece of paper or hard cardboard underneath the digitizer ribbon cable just after the connector.(refer the circle part in the picture below)

Hope it fix yours.
I replaced the logic board of my LG G3 with another one - because of a CPU issue. I realized that the phone did not have any touch input signal. Nothing at all. The new board is not defective - I tried another one just to make sure.
I am very confused right now since I don't know what the problem could be, I just removed the connectors and then put them in place again like they are supposed to be. I didn't do anything at all with the rest of the phone besides exchanging the logic board. What could be the issue and how can I fix it?

I have an 8.3 that has its wire cord broken. For reasons, I need the exact cord replacement. LG does not sell it. I can't find one while googling or maybe I just have weak google-fu. Can anyone point me where to buy it? Does anyone here do?
Photo below is a screencap from a site selling the tablet with this cord.
