Switch OLED - USB-C D+ \ D- OL

[GBAn00b1e]

Looking for some help to see if there is anything I should be checking on an OLED for OL readings on the D+ and D- lines. Bought a OLED off ebay that needed a port replacement, but after replacing the USB-C port the D+ and D- lines are showing OL readings. Any help would be greatly appreciated.

D+: #1 should equal #2
D-: #3 should equal #4

if you have value on #2 and #4 but not #1 or #3, replace the choke filter in between

I assume I would need to measure in diode mode?

Looks like that choke is bad. I could have sworn that I checked that choke before, but I guess not. Any idea on the size of the choke filters used on the OLED switch? It doesn't seem like they are the same size as the ones on V1\V2 or Lites and I would like to order some and not have to depend on donor boards.

As an update in case someone stumbles across this thread. I was able to grab the same size choke off of a lite donor board. I also found them on Ali and purchased some. https://www.aliexpress.us/item/3256...st_main.9.53781802Z1gB5i&gatewayAdapt=glo2usa

Thanks to jkyoho for his help. My issue appears to now be resolved.
