please check some of the thru hole components.
some of the components radial axials on the ex800 had long lengths ,
so long that the way they were bent could have triggered a short/malfunction

Most likely, the problem is with the sequencer
enable switch or with IC33 or IC34.
I would start by checking the switch
using a multimeter. If it is not the switch itself, then
replace IC33. If that does not fix it, then replace
IC34.
