ps3 DS3 not functioning L1 & L2, defect cannot be traced

[gameRPG]

---

I need expert opinion regarding sa possible defect ani akong controller or some of you in the same situation before. So annoying if wala ni nga function in playing FPS games...So ako na lang jud giukban although naukban naman ni before sa original owner...i found out ok ra ang rubber ok pa kaayo, dili sya stuck, wala pa juy gisi...ako pud gicheck ang ribbon, ug limpyo ra pud wala man pud maputol ang connection...I'm wondering unsay guba jud ani...or asa ang defective...I tried using the controller nga naka on ang pressing the L1 & L2 using the screw driver to the rubber but wala juy effect...I tried sa functional R1 & R2 pero ok raman, same manner of pressing it...HMMM......DAKO BA UG CHANCE NGA ANG RIBBON NAGUBA ANI? murag wa jud koy laing mapasanginlan.. possible ba pud ang PCB board ang defective? I need expert here ug thanks for reading...any opinion well help...thank you...

im not sure ha sa PS3 controller.

but i have opened PS1 and PS2 dual shocks and some controller has flex connector between main PCB and the L1/L2 PCB. and some do only have one pcb. the whole is a flex PCB.

wala pa jud ni sir masulbad gahuwat ko sa sweldo para maparepair ko ni i think jud sa flex ni ang defect...or maybe buy na lang ko ug new...@ X, yup boss very familiar pud ko sa ps1 ug ps2 controllers...most likely basta walay flex kay class a jud na nga controller...
