Measure the Resistance of the R3 button line there to ground.

I'm so new to these kind of stuff

Can you show me how to do it on the pic please? Just tell me where to put the probs

The soldering pad for the red one is completely ripped off, is it ok to connect the prob to the pin itself?

RDC · « **Reply #363 on:** November 03, 2022, 07:32:59 PM »

Use the pin below it, straight down from the red dot.

Not sure if i did it correctly, but i got 0.05 (the range set on 20k Ω)

Yeah that's not right, that would mean the R3 line is grounded and in that case it would never work. The proper way to test it would be to remove the stick and check the R3 line again, but, and no offense intended, I'd be concerned about more damage happening to it during that process.

Yeah you're right. isn't any other option to workaround the problem? i'm mean without removing the stick

UPDATE
When i touch the red dot with my finger R3 act like this:

Thing still looks to me like the PD Resistor isn't in circuit and that R3 line is floating. You can try putting a 100k Resistor from the R3 line to Ground and see if that fixes it.

You mean that little Resistor you mentioned earlier? I guess you're probably right cause when i touch the board around that area (red dot) with my finger everything works flawlessly
Still don't know how to fix it though

RDC · « **Reply #369 on:** November 03, 2022, 08:41:17 PM »

Put a 100k Resistor between the 2 dots.

Ok i'll try to do that (need to buy that Resistor first) and will keep you updated.

Thank you so much for taking the trouble to help me. I really appreciate it

Semtex · « **Reply #371 on:** November 05, 2022, 08:18:17 AM »

UPDATE
I soldered this Resistor (still not soldered in the pic) to those two dots you mentioned, but it didn't solve the problem, and now i don't know why but my L1 button doesn't work anymore even with the Resistor detached!

I think at this point it's better to give up on this controller

LethalPrime · « **Reply #372 on:** November 05, 2022, 08:47:51 AM »

Doesnt look like its actually soldered on looks barely even cold soldered on

Semtex · « **Reply #373 on:** November 05, 2022, 09:11:01 AM »

^As i said in my post the picture is taken before the soldering

RDC · « **Reply #374 on:** November 05, 2022, 09:33:16 AM »

Clean the contacts where the motherboard and Flexible Printed Circuit board (FPC) meet, just use a Q-tip and rubbing alcohol. Also make sure the foam piece is under the contacts of the FPC as it provides pressure on those contacts. Also the controller has to be together for those contacts to make a good connection or the buttons on that FPC will sometimes not work or do weird things.

Make sure where the Resistor is installed it's not interfering with the controller going back together or it's not going to make that connection right either.

Semtex · « **Reply #375 on:** November 05, 2022, 01:35:45 PM »

I did everything you said and it worked! Now everything works perfectly except the L1, i noticed one of the traces in FPC is damaged so i need to replace the whole ribbon. But everything looks good so far.

I need to thank you again sir, Couldn't done it without you!
YOU ROCK!?

Hallo, may someone give me the values of 2 resistors and 1 capacitor on the jdm 030 pcb? It's next to the right analog. https://imgur.com/a/avku9zp

Mbithi · « **Reply #378 on:** January 05, 2023, 03:03:47 AM »

Will that method work on a jdm 055 with the same issue?

Ivanlakersss2016 · « **Reply #379 on:** January 11, 2023, 03:30:36 AM »

Hello, I would like to know what values of smd capacitors this jdm-001 board model has, where the arrows marked in the photo, where the yellow circle is, were lost while resoldering with the heat gun, removing a movement potentiometer. I hope your help, thank you!

RDC · « **Reply #380 on:** January 11, 2023, 06:51:03 AM »

All of them are Resistors.

Ivanlakersss2016 · « **Reply #381 on:** January 11, 2023, 04:06:26 PM »

resistance 0 is like making a bridge with a wire for example, right?

ZhenyaKa · « **Reply #382 on:** January 12, 2023, 11:44:28 AM »

Thanks for reply. Can anybody help about values of these two parts?

And one more question. Can I short 5V from black front port to usb 5V port for chargin via USB?

RDC · « **Reply #383 on:** January 12, 2023, 01:19:44 PM »

@ Ivan - Yes.

@ Zhen - Both are Caps, 100nF and 33pF, neither are really necessary. No idea what that would do with the 5v.

Thanx a lot. Will replace BD92003 chip.

I have a problem in my jdm-001 motherboard, from arrow number 1 I need a 100 ohm resistor and it makes it impossible for me to solder to the track because it is very small and not
stick my tin, I had thought of a bridge to arrow number 2 with a small fine wire, it is possible that this track leads to that path or I am wrong, I need help @RDC

RDC · « **Reply #386 on:** January 19, 2023, 08:07:56 AM »

Those spots are not connected at all. You have to remove the green solder mask and expose the copper trace for the solder to stick to it.

pingggponggg · « **Reply #387 on:** March 18, 2023, 12:23:27 PM »

Correct me if I?m wrong, but I only see the D-pad R, L, U, D vias labeled for JDM-001. Does anyone have the locations labeled for the four D-pad buttons on all the other DS4 PCBs?

pingggponggg · « **Reply #388 on:** March 18, 2023, 09:49:31 PM »

Specifically, if someone could please help show me the locations of the D-pad vias for JDM-040, JDM-050, and JDM-055, that would be greatly appreciated!

RDC · « **Reply #389 on:** March 19, 2023, 03:50:51 AM »

I stopped hunting for all of the vias ages ago as it was killing to many controllers. I made up the SFX to have much easier and larger places to solder to for all of those buttons, so no more vias had to be harmed during the making of controllers. https://acidmods.com/forum/index.php/topic,44001.msg337947.html#msg337947

The -050 D-pad spots have been added, the -055 is the same. The -040, from a quick look, doesn't seem to have one for the DD, so feel free to strip that one down and find out for sure or not.
