| TAM screen gone blank |
Posted by: jdlanza on 2020-12-19 11:51:30
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!? 🙂

Reset PRAM, press CUDA switch - replace PRAM battery if < 3V

@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!

Perhaps because it's CMD-OPT-P-R?

Perhaps because it's CMD-OPT-P-R? Which is, of course, what I meant!

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.

Chiming in wayyyyy late but recently had an issue like this. If you push on the top left of the machine near the lcd/speaker area and restart the machine it may fix it. You see there is the LCD cable there. Sometime it gets knocked loose, even the slightest disconnect can cause this issue. Not saying that’s the issue here but it’s worth a try or part of the troubleshooting process. |
