HP 1662C logic analyzer/scope, ROM failure

I bought a faulty 1662C logic analyzer for parts. Now as I got it, it
is in too good condition to not try to fix.

At startup I get ROM test fail message, all other tests pass. Is that
a common problem with this model ?

According to the service manual, there are an ROM for the boot-routine, then there are Flash-memory and a non-volatile RAM too. Which one causes this problem ? Do anyone have a hint how to fix it ?

Thanks for help.
