Help Needed with Pinout Reverse Engineering For Xiaomi Redmi Note 5 screen
I am trying to get the pinout of a Xiaomi Redmi Note 5 screen. I have been able to identify 14 GND pins, 5 differential pairs, and A K1 and K2 (for the backlight) I also found a pin that will short with GND for a second then flash off then back on, and then another pin that shorts with GND, but will also short with a bunch of the capacitors and resistors on the flex PCB.
If anyone has any ideas or tips on how to figure out what the last 11 pins are, I would greatly apricate it! I have no clue what to do from here.
Here is my current list of all the known pins.
| 1 | GND |
|---|---|
| 2 | |
| 3 | GND |
| 4 | |
| 5 | |
| 6 | |
| 7 | GND |
| 8 | Saying GND then flashing off then Back to GND over and over and over again. |
| 9 | GND |
| 10 | GND |
| 11 | |
| 12 | |
| 13 | |
| 14 | GND (Shorts with Resistors and capacitors) |
| 15 | GND |
| 16 | A |
| 17 | |
| 18 | K1 |
| 19 | K2 |
| 20 | GND |
| 21 | GND |
| 22 | Differential Pair |
| 23 | Differential Pair |
| 24 | GND |
| 25 | Differential Pair |
| 26 | Differential Pair |
| 27 | GND |
| 28 | Differential Pair |
| 29 | Differential Pair |
| 30 | GND |
| 31 | Differential Pair |
| 32 | Differential Pair |
| 33 | GND |
| 34 | Differential Pair |
| 35 | Differential Pair |
| 36 | GND |
| 37 | |
| 38 | |
| 39 | GND |
| 40 |
