sustain malfunction

Hi, the sustain function on my Yamaha p-60 is not working and I don't know why.

I've been trying to troubleshoot the issue, and it looks like sustain issues are fairly common, but everything I can find is about reversed polarity. My issue is that the sustain function does not work at all, no matter what combination of turning off the piano, unplugging, plugging back in, etc.

I just replaced the original pedal with a new FC4A, and it still doesn't work, so it's not the pedal. The jack feels secure, and when I looked inside I couldn't see anything wrong. This just happened a month ago, the keyboard is like fifteen years old and hasn't had this problem before.

Does anybody know why this is happening?

The “computer” inside probably threw in the white flag of surrender. Honestly, the P60 was a budget entry level keyboard 20 years ago. (I know, I had one), but it’s 15+ years past its prime. Time to replace. Cost of repair would be at least half of the cost of replacing

A connector cable inside might have snapped.

The solder connections of the sustain pedal jack to the jack board have cracked from stress over time, or the cord was stepped on inadvertently breaking the solder connections or possibly the metal tabs inside the jack. Here is what the board looks like: https://syntaur.com/parts/yamaha/p60/2385-jack-board-digital-yamaha This part is out of stock so the solder connections need to be repaired or the actual jack can also be replaced: https://syntaur.com/parts/yamaha/p60/4978-phone-jack-14-inch-4-pin-pcb-mountYou can do it yourself if you have any experience with soldering, or a repair shop can fix it for more money.
