im getting a juno 106 with 10 dead keys in a row in the middle of the keyboard has anyone got any ideas what might be wrong , its not voice chips , id be surprised if its dirty contacts what do you reckon? btw where are you jiding the repair section i cant find it feel free to move this

having never seen a juno service manual, so i'm just guessing:
sounds like one of the commons of the keyboard matrix is out/disconnected.

hint: get a service manual

yes i wil,
l i havent got it yet its coming monday i was hoping someone on here had experience of the same j106 prob save me looking

here's the service manual.

on the bottom right of page 10 there's a printout of the keyboard matrix, which is 8 by 8.
(well, only 61 keys, so three unused combinations.)

now, if one of the lines on the right hand side (CPU board connections 5 to 12) is failing, you'd miss a block of 8 keys in a row.

sure it's ten keys you're missing, and not eight?

rip the keyboard off and turn it into a module
