[comp.sys.mac.hardware] RasterOps 264/IIcx display problem

johnwl@kean.ucs.mun.ca (07/17/90)

  I have a hardware problem that I hope someone could enlighten me on:

  I have a brand new RasterOps 264 card that I just put into a new IIcx
to drive an Apple 13" colour monitor.
  The machine boots fine, with the gorgeous RasterOps startup screen, but the
disply remains VERY dim.  It also flashes between bright (normal ?) and dark
light levels at odd intervals and eventually fades to black some minutes later.
  I have tested all connections, tried the card in different slots, tried the
monitor on another Mac II (it works fine), fiddled with settings on monitor
and Control Panel: all to no avail.
  I have yet to put the card in another Mac II; I guess that would be the acid
test ...
  Has anyone had/seen/heard of this problem ?  I am just borrowing this machine
for a couple of months (it has AppleCare), and hope I don't have to send the
card back for repair/replacement !

It sounds like you have PYRO! INIT up. If so - take it out.
