Pinout of the Click Wheel or LCD to logic board ribbons?

I have aleast 3 Nanos this generation that has click wheel issues and a replacement click wheel does not work. I would guess the actual ribbon cable to the logic board went bad. My question is, does anyone have a pinout of where each pin connects to on the logic board? I would like to check each pin and would help everyone further understand Click Wheel related issues.

On a side note, I have found a few of the pins on the board. I am also looking to get a pinout from the LCD screen to logic board.

Ahh didn't think of looking there, that should be detailed enough for what I am looking todo, thanks a lot!

Do you happen to have any info on the LCD screen ribbon? I know the left pins are related to the backlight power source, but that's about it.

I got the one for the %G video still scouring for the nano. Here is the one for 5G video:Connector pinout pin 1 - nearest the edge of the LCD frame

Pin Function

1 Not Used

2 3.1V Supply

3 1.8V Presumably I/O supply. All I/Os run at 1.8v levels.

hopefully this pin can be set to 3V or 3.3v for 3V IO - I'll wait til I have ID'd the controller, or have an expendable display before testing this!

4 0V

5 /Reset.

6 /CS Chip select

7 /WR write strobe

8 RS Selects command/data register ( called CD in some datasheets)
