Does an ohmmeter show them as open or not?

The fuse resistor that didn't blow reads exactly 1.04 ohms (that's an
in-circuit reading).
The fuse resistor that blew reads open circuit....and that is with the
resistor TAKEN OUT of circuit completely.
I figured I could replace the fuse resistor with a regular 1-ohm
resistor and get things working again, but I also realize that that is
NOT safe, and so the deck will not be powered up again until it has a
new 1-ohm fuse resistor in place...and I might even replace the other
1-ohm fuse resistor whilst I'm at it.
I wouldn't excessively fret over not fitting a genuine fusible resistor. The
only difference between them and normal resistors is that they are (a) designed
to fail open and (b) are flameproof. There's still another one in circuit !
If one of those fusibles had failed (as it seems) that's why you have no
display.
