TAM screen gone blank


Recommended Posts

Hi all - I have a TAM that was working fine until, as these things go, it wasn't.  My PM 6100, PM 7100 and IIsi all reported that the TAM had unceremoniously departed the AppleTalk network.  Restarting the TAM results in the satisfying "bong," but I get nothing on the screen.  It also does not reappear on the network.

 

Thoughts?  Thoughts other than recapping the TAM!?  :)

@Byrd, thanks for the thoughts.  I smacked my forehead when I read "Reset PRAM."  Did that, and got to the screen that said the Mac hadn't been shut down properly (you think!?) and was checking the disk.  The TAM hung there.  Powered off and on.......and got nothing.  Now the PRAM won't reset, either.

 

I'm assuming the HD has gone and needs replacement, but the PRAM behavior is odd.  Any ideas why CTRL-OPT-P-R wouldn't be working?

 

Thanks!

It happened to my TAM previously with a bad HDD. It will chime with black screen. Unplugging the ribbon on the TAM will work. Try it.

I will suggest removing all peripherals and cards and booting with a minimal setup, had this issue once, was a card preventing the full process. 

 

Can also be a screen issue, but as you are saying you lost also the network, probably more something else.
