Hi all I have some questions.
I did not notice a repair section for hardware, did I miss it?
If so please throw this in there.
Now that that's out of the way, I just got in a roland sc-88.
it has a few scratches and dents but overall looks ok, but it is non functional.
I know someone has opened it before me so that's strike 1, I did a once over and noticed bad caps on the main board.
there were 5x 10uf at 16v and 1x 100uf at 16v, after replacing them all no change.
So I looked at the power / analog board, all the caps looked good but 2 voltage regulators had bad solder joints, repaired them still nothing.
I checked the voltage on the top left pins, all were correct.
also I checked the battery because I saw a post on that about sc-55's. it was good.
and lastly reconnected the plugs for all connections, did not fix it.
so right now I'm a little stuck, I was going to go through the daunting task of checking each chip but I thought I would check with you guys.
