Ok, first of all. The story is began from a trigger spring broken in my PS5 controller. So I notice that my controller R2 spring was broken. I go to Youtube then watch the guide for how to tear down this controller. I was found a broken spring at the R2. So I try to take out one trigger spring from PS4 controller but notice that the PS4 trigger spring is different from PS5 trigger spring.

So I try to remove the L2 spring too to replace all to PS4 trigger springs. Ok, problem temporary solved but the PS4 trigger springs not as tight as PS5 original trigger springs. So I order from shopee and wait for it arrive. After a week, finally get my PS5 trigger springs. I can easily install the spring on R2 trigger but the L2 trigger is far more difficult to install because it is heading inside.

I do not tear down the motherboard complete to install the L2 trigger spring. So after that gg, I scratched the LR conductive film ffc. So I was ordered from the China seller in shopee then wait for another week then arrive at yesterday. So I happily go back home to replace the new LR conductive film. Finally it gets work but the L2 motor not working. I guess both L2 motor and the left vibrator motor are not working.

So I tear down the controller to check again and I found the orange ribbon was broken (item from picture). Which is caused by pull out and push in the ribbon too often. There have 4 pins disconnected due to the cable being torn out to half (broken).

So now I am looking for replacement. The problem is this specific cable is not able to find in the market. I am now trying to figure out and seeking for recommendation.

Can I replace to this type of cable?
16-pin 0.5mm flat flexible cable

Thanks anyway, I manage to take out a 20pin flexible cable from a used damaged laptop. Then cut down 4 pins on both sides, so make it became 16pin. It works!
However, about the question on some of the wires inside the original FPC have different thickness. I was now replaced to a standard FFC, all the wires inside have the same thickness. (Ignore this sentence if you not understand what did I say)
I can noticed that my L2 button has more solid than the R2. The left L2 button has more tactile than R2 but the L2 vibrator is lighter than R2.

Looks like u already manage to fix ur dualsense. But I found this FFC on Shopee but not sure its the same or not

My suggestion is getting the 16-pin from here. 5cm is long enough for the left trigger (actually 3-4cm is the perfect length for left trigger). I think it is suitable for right trigger too.

just sent for warranty la

if not MY set cannot claim warranty lol

Better to just get MY set.

Well as for me lucky got the 1st batch. Others sometimes didn;'t want to wait so get the JP n EU set and hard to claim warranty

Today I was received the 5cm length 16pin (0.5mm) flat flexible cable. There have no different by comparing the Sony stock flexible printed circuit.


I remove the stock FPC of right adaptive trigger then replace both left and right trigger to FFC.


I decide to replace the right R1/R2 trigger conductive film to the new one which I previously bought in Shopee.





There have two different types of LR conductive film. Which are "42" and "38". The one with "42" usually are using by Sony stock controller. However, if replace to "38" LR conductive film, vibrator has more silent and solid on vibration. It is hard to explain, just look at the picture below.
