Title: 1537 RB Not Working After Button Replacement
Post by: demuffin on September 12, 2021, 11:35:45 PM

Hi all,

As per the title, I have checked all soldering connections and everything seems proper. I have done a continuity test on the pins of the new button and it works. But the computer does not recognise RB when it's pressed. Any help will be greatly appreciated!

Why was it replaced?

Schematic for that controller is in the 1537 pinned thread. Not too many places it could fail.

During initial testing, I realised that the RB was not reponsive so I decided to change it out for a new switch. Before I did the replacement, I did check if the new swtich is working. After re-soldering back the new switch, I tested the controller on my computer but still no response. I checked for continuity on the traces and all seems fine.

Is the main big chip on the right of "1537 MCU BOARD BOTTOM" prone to failures?

Just about anything can happen, but a damaged trace/pad or bad trace or via from the RB to the MCU is usually the more likely cause.

I had this exact same thing happen to me. It was fixed by reflowing the diode(D3 i think) and the cap next to it

Thank you all for the reply.

I decide to give it a try again while referring to the schematic diagram and I found out that there might be a broken trace from the pin to the MCU. So I tried to solder a jumper wire from the connector pin direct to the MCU.

This was what I've done and it actually works! I was so amazed and I couldn't control my laugher after that  :huh:

Interesting. There is only 1 via in that entire trace from J6p5 to U1p3, and you can see almost the entire trace, minus a little bit of it that is under the RF module. I'd have to desolder the wire and see if it went back to fail mode, meaning the trace or via is the issue or if it still worked, which would mean it was just an iffy solder joint at U1 or J6. Either way good job.

Awesome. Thanks for the help and kind words!  :laughing:
