🔧[BDM-020] R2 Trigger Permanently Activated – Even Without Flex Cable

Hi everyone,
I’m dealing with a ***PS5 DualSense controller (BDM-020)*** that has a persistent issue with the ***R2 trigger input being stuck "on"***, even when ***no trigger or flex cable is connected***.
Here’s a full breakdown:
=== Symptoms: ===
* ***R2 is always registered as pressed***, even without the flex cable or trigger module connected.
* When I reconnect the bumper flex cable, ***R1 works***, but ***R2 remains constantly active***.
* The actual ***R2 trigger module works fine on other controllers***.
* I also tested ***other working trigger modules*** on this board – ***same problem***: R2 stuck.
* I noticed that the ***pins of the flex cable s***eem to ***bend slightly when inserting the cable inside the FPC connector (trigger flex slot)***, which might suggest mechanical damage to the connector.
=== Board info: ===
* Mainboard: ***BDM-020***
=== Questions: ===
* Has anyone encountered ***R2 input being stuck "on" at the board level***, even with no flex cable?
* Could this be caused by ***damage to the FPC connector***, e.g. shorted or internally bridged pins?
* Is it possible to ***replace the trigger FPC connector*** or clean/fix individual pins?
* Any specific points I should ***probe with a multimeter*** to isolate the issue?
I’d love to hear any suggestions – I’d prefer to repair this board if possible instead of scrapping it.
Thanks a lot in advance!
