Chosen Solution

Hey people sorry for asking so frequently about ds4. But after my last question about stick replacement i finally replaced my analog stick, but i found out after i reassemble the controller together that its not working right.

(the replaced stick is stuck to the left, the R2 & L2 is pressing on its own *not physically). After that i dissasemble it again and check the potentiometer with a multimeter and its all in a normal range(i don’t really know what the numbers meant but it’s the same as the original one). Any ideas what causing them? I have a theory because i also found out that the 12-pin ribbon cable (from the back casing to the board) is messed up

is that the source?

Sorry but as said before the ribbon could be the cause. Also, no offence but those solder joints are really bad. It actually looks like some aren’t connecting the the board which could also be your issue. Did you use flux? If so do them again and go slowly. If not buy some flux and them do them again.

The ribbon cable is probably the problem. You will have to replace it. Try connecting the controller to a computer running a program that recognizes controller inputs after you replace the ribbon. You will have to either solder the old one or replace it with a new one and you may have to solder that.
