Have you tried holding down the Write button when you turn it on to enter diagnostics mode? --- In korgpolyex@yahoogroups.com, "eshalsall" <eshalsall@...> wrote: > > I noticed another thing when I turn it on.

When I turn it on the display flashes "88 88 88" and doesn't change to the "HA-800" as said that it should in the manual. I tried to test all of my work after this happened. I replaced the two original chips, desoldered the cpu write jumper and the synth worked fine with the original configuration. I checked continuity on the ribbon connectors. I also checked every solder joint on the hawk board and that the chips were in the right place. > > > > I have the boot ROM v. 1.95 > > > > Please help > > > > Thanks, > > > > Ethan > > >
