Dead Spot in simetsu ls-32

I modded my Xbox 360 Real Arcade Pro. EX with a simetsu ls-32 now when I play blazblue the left direction (forward from the 2 player side) seems to have a dead spot so sometimes the chracter isnt moving forward until i keep repeating the motion.

It’s also affecting my down-foward.

I checked the quick disconnects and the soldering they are good.

What else could it be???

Faulty PCB?

I’ve had the Joystick for about a year now and I took a look inside to see if i could see anything wrong with it.

However, I don’t see any cracks or unsoldered joints on the PCB.

Is there any other way to tell if something is wrong with the PCB?

check the quick connects on the stick. tighten them
