Aion FX Cygnus PCB - Burnt up LED Copper Pad - Any way to jumper power to it?

[laundryman]

So I was confused by the Cygnus Build Documents (https://aionfx.com/app/files/docs/cygnus_documentation.pdf) at the LED and soldered it on backwards, then toasted the copper padding trying to desolder it.

Hoping there's a simple way to just run a jumper to it from another component.

The cathode of the LED that I destroyed is circled in red:

Placing a jumper from the FX Out on the mini-board to the cathode of the LED does power it on, so I know its not burnt out.  However doing that makes the LED stay on regardless of whether the footswitch is activated or not.



Thanks!

Welcome to the forum.

It would help if you told us which pad - or highlighted it on the drawing. Pics of the damaged board would be very useful.

Oops, sorry about that.  I just edited the post.

Thanks again

That square pad gets the long lead of the Led - if you haven't cut them.  One side or the other of the "LEDR" should get the long leg of the LED. So take a look at the traces.  If you've cut the legs off the led already, look for the little flat surface along the bottom edge of the Led.  (This would be the short leg side.)This flat side goes to the round hole.

Thanks, gonna try to fix it up tonight.

This is the part that confused me.  The PCB itself and the build documents had conflicting labels for the LED, and everything I looked up online said that the flat side of the circle & square is the Anode, but the PCB itself had a square symbol on the full circle side.

Thanks for the help.
