I need this Trinity part!!

It's the circuit board the keys strike to sense velocity and notes. I accidentally put a chip in mine repairing some keys and now one whole octave does not work. I've been searching and have no idea where to get parts like this for the Trinity. Here are a few pix of what I'm talking about.

Thanks

Ouch!

That would be pretty easy to fix though. You can see the circuit track that's open. If you carefully scrape 1/8" of the coating off of that track on both sides of the chip you can then solder a small guage piece of buss wire to the track and bridge across the break. 15 minutes with the proper tools and you're back in business if that's all that's wrong.

Hmm...I think I'll give it a try. What would be the proper tools for the job?

Thanks.

You need an xacto blade to scrape off the coating, a soldering iron. solder, wire strippers, and some small wire to solder across where the piece is missing.

The following site sells Korg Parts.

If you must insist on doing it yourself, they probably have the part.

Thanks, I never noticed the "Korg Parts List" on the right side of the site before. What is the part called? Could it be the contact board? None of the part numbers pair up with what I have.

Thanks.

Ok I found out what the part is!! It's the upper keyboard contact board. So my next question is will it interchange with the Triton's upper PCB contact? From picture I've seen they look exactly the same with the same connectors and wires. This seems to be easier to find than the Trinity's parts.

Thanks.
