Unresponsive LFO Trig button and patch buttons on Juno 60

[NCChao1268]

Hello everyone,
I have a Juno 60 which has an unresponsive LFO Trig button, does anyone know how to fix it and restore contact to it again? I heard it is just cleaning the rubber where it makes contact? Feel free to correct me.

Anyone know how to fix non working patch buttons (Not the hold and arpeggio buttons that stay depressed)?

Thanks.

tech tip clean the pad area with 95% rubbing alcohol first before reworking.

Thanks for responding, got it fixed using some 99% alcohol to clean the contacts and some graphite powder to restore contact. It was a bit tough removing the springy assembly of the LFO Trig. It was a badly designed part which the left side has the spring assembly and the right side is a dummy part.
