The DualShock 4 CUH-ZCT2 was announced in 2016 to replace the CUH-ZCT1 controller released in 2013. This controller is similar to the previous model.

Question about damaged JDM-050 motherboard

Hi,
I got an old DS4 motherboard that has been scratched badly. The previous owner told me the controller worked before he tried to fix a stick drift problem, hence the scratches. I tried to assemble the parts together and get some LED blinking, but the controller did not work.

I'm quite inexperienced in this, so I hope someone could help me take a look if this board could still be restored to working condition or if it is totally dead. I found that a component next to the left thumbstick (zoom-in pic with arrow) might be deformed/melted. Maybe it is also a problem?

Many thanks :D

So...you have what looks like at least 3 vias that are destroyed. That component in pic 3 looks like a diode and yeah it looks toasted. Also in the first pic, right side see the golden number 4 in a circle? If you go a bit up from there it's hard to say for sure but looks like there might be a damaged trace.

Diode replacement, verifying and fixing that trace, bypassing/restoring those vias.......all doable, but definitely not a job for a beginner. However!!! She's dead at this point, therefore it's the perfect place for a beginner to start learning! Nothing to lose.

I'd start with watching some videos on running enameled wire to repair the via's. If you can manage that part the rest will be easy.

did you try to inject 3.6v from the battery side ... in my controller jdm 050 i found the problem next to the tc7736ftg capacitor and resistor, but the big problem is that i don't have now idea about the resistor and capacitor value , and there is no diagram or data sheet for the tc7736ftg ...
