C5, C6, C7 and C8 are all part of the RF filter and need to be pretty exact value wise. I doubt my meter is that precise, and accurately measuring 0201 components is about as much fun as trying to put a leash on a flea. Best thing to do there would be to get any of those parts from another board.

Thanks! What if I make a short circuit instead of replacing the capacitor C5?

@ Dzrn - Never short circuit where a Capacitor was, ever.

@West4it - There is no easy spot to solder a jumper wire. You will need to solder the wire from the lead of the POT to a Via.

i thought motheboard had pins from both side and i can find another place for solder. why they do this "pins" not normal roads....
anyway, thank you , works fine  :clap:

Hey guys, is c37's value critical, if so, does anyone know it by any chances?? Amazing work by the way, thanks for putting so much efforts in doing something that should be required to be done by the manufacturers, but is not, because filling their pockets with pieces of paper and chunks of metal is so much more important than saving the planet... :clap:  :tup:

C37 is 10uF and that one I would replace.

Nice, thanks for the reply, and yeah it's shorted and now my controller will only work while plugged, was gonna order a battery but decided to swap batteries with my other controller first just for fun, but it was still the same, decided to check the voltage and both batteries where fine outside of the controller, but they drop to 0.3v when i plug them in... so yeah, if it happens to anyone else, i'm pretty sure that C37 is the culprit since it's the only one i found that's shorted!! So thanks again, i'll order some caps and post back here to confirm if it's the case as soon as i get the chance to swap it!! :yess:

I have a jdm-055 with D-pad "Up"and R1 always on. Once in a while L1 also stays on. This is the case with flex cable removed (bare board connected via usb). I checked on the flex  connection area J5, i am getting 1.6V on pin 6 and 2.3V on pin 15 (i believe they should be 0v in idle condition). Didn't get any voltage on pin 2 (as L1 problem comes and goes; not continuous issue). All other buttons, analog, L2 R2 etc works fine.
Is the ic MT3610 the issue as there is no other component to check as per schematics?

There are Pull-Up Resistors built into the flex board, PU1 and PU2, and with that thing not in circuit like that the L2/R2 lines are floating and the controller can do all kinds of weirdo things. If you are wanting to run the board alone like that, then you need to install a couple of Resistors on there to mimic the flex board being installed and then see if it has any issues. A couple of 10k will work fine for that.

I tried another good working flex cable. Still the same.

Didn't say flex cable, said flex board, the one that has all of the button contacts on it.

Do you have the controller all together or not?

the button flex ribbon cable was cleaned with dry cloth and board was cleaned with IPA. It didnt work so i tested with a flex ribbon cable from a known good controller, still the same. During all this steps, controller was put back together with all screws and the casing was snapped together for proper pressure / contact.

As it didnt work and now knowing something on the board was the issue, I used flux and ran soldering on all pins of MT3610 and S2PG and it WORKS now. I dont have the skills to lift MT3610 IC and resolder it to the board (it has 2 rows of contacts which is a first one for me). But finally if nothing worked i would have done that. Glad it worked. Thanks for the help RDC.

Welcome. That piece of foam in the top half of the controller that keeps pressure on those contacts can come out of place, or need a shim behind it so it puts a little more pressure on the contacts when things are back together.

Yes i understand. Foam seemed to be in good shape and I never changed it. After reheating pins and adding flux, the pins have become white. Almost all pins were dull and dark. Maybe corrossion? I don't know. Anyway it's working great for now.

I have posted another question in a new thread about jdm11. Its very old controller but I'm really bumped by the issue.

Hi, i did short something in area 1 and now i have 0,37v on the 2 area. Did i short ICC chip, or maybe this one on the back of the PCB which is right under the battery outlet?

The chip on the other side under the battery connector is for the 6-axis, doubtful that's the issue. If you have 0.37v at the battery connector, then either that battery is bad or something is getting crazy hot in there and that's the bad part.

The battery is fine. When the battery is 4v it reads 0,4v; another battery 3,7v it reads 0,37v it drops by one decimal place. What could cause this? Does ic chip could be damaged??? but how it drops right away on the battery outlet????

Nothing is going to make the battery voltage drop 4v and nothing gets hot, unless the battery is bad or your meter isn't setup right.

Meter and battery are fine. On the same meter setting battery alone shows 4v. After plugging in it, drops to 0,4v. Tested on 2 different working batteries.

Hallo guys, does anyone know the value of the C41? There is also an capacitor on the same spot at the left analog for which I need the value too(https://imgur.com/a/GGeKIcz). Thank you in advance for your help!

Both of those are just on the 3.2v rail for decoupling, the value is not critical. They could be anything from 1nF to 1uF, and it will still work fine without them.
