    30" Apple Cinema Display

    Yep, I've seen the posts you reference, and understand that Apple has never acknowledged the issue. My display is now over 10yrs old - still working fine otherwise (amazing in itself), and 4-5 of those years with the problem we're discussing here, but was hoping one of the electronic wizards in this forum might have an idea about what component in the monitor might cause this behavior... Thanks

    Nope. The status light on the monitor does the following. Display on - status light off Plug in either USB or Firewire to host computer - Display off - status light off Put computer to sleep - status light on (solid) I also have a 2nd monitor attached to this computer - a 23" Cinema Display, and status light action is consistent on both monitors. USB & Firewire from the 23" ARE connected to the computer, and work fine.

    30" Apple Cinema Display

    I have a 30" Apple Cinema Display that works fine until you plug the display hub connector into the computer. When you plug either the USB or the Firewire connectors into the host computer, the display goes black. Unplug them, and the display comes back on. I have had 2 different power supplies - same thing happens on them both. I believe others have seen this issue with these monitors, but I have not seen a solution. Any ideas about what may be causing it? Capacitors somewhere in the display? Faulty power board in the display? Would love to figure out how to fix it - it's a great display otherwise.

    Apple 30" Cinema Display Monitor

    Has anyone ever figured out a solution for the USB problem described in the first post here? "The only problem it has is the USB hub causes the screen to black out when it is connected to a Mac." I have a 30" that I use daily -- it has this problem. Could it be caps on the USB board?

    Color LaserWriter

    And that's the reason that I asked the question here before pulling the board. I checked the service source first, and there was no mention of a battery so I assumed that it would not have one. Luckily on most Apple printers, the controller board is fairly accessible. I know all the LaserWriter IIs, Personal LaserWriters, and this Color 12/660 have controller boards that just slide out for upgrades & such. My 16/600 and 8500 are bit more trouble to get to, but not THAT difficult. I'll be checking all the printers I have around.

    Color LaserWriter

    I should have pulled the controller board before I asked the question. Did so this morning, and there sat a dead, but intact (thankfully) red Maxell 3.6V battery. Have ordered a replacement and should be good to go.

    Color LaserWriter

    I have an old Color LaserWriter 12/660 that I'm trying to get going again. It has sat for several years, plugged in, but not turned on. It still works, but it no longer holds any configuration settings sent to it after a power cycle. Does anyone know how/where LaserWriters store the config/IP address information sent to it? Is there a battery in it that just needs replacing? Are the configurations stored in EPROM somewhere and could that chip have gone bad???

    Flaky ethernet on SE/30

    The problem ended up being the ethernet card itself. Bought another MacCon ethernet card off eBay, and though it did not work at first either, after examining it, and cleaning up a bit of dribbled rust on one of the ICs, it worked fine. Switched back and forth, and isolated that my original card must have something hosed on it... SE/30 working fine now with both the Diimo accelerator card and the ethernet card inside. Thanks for all the suggestions. and thanks to Uniserver for a great job recapping.

    Flaky ethernet on SE/30

    Uniserver did the recapping, and word is around these parts is that he does excellent work. But the problem did start when it was recapped. But otherwise the computer works fine, and works fine with only the accelerator card in it... It's just the wierd thing that the ethernet card is seen by the computer when it's in the machine by itself, but not seen at all when it's connected atop the accelerator card... This was the exact same configuration that it was in before I sent it off for recapping - and both cards worked fine then. I don't think it's the cable. I've tried both a standard 4 port 10MB hub, and also an 8 port 10/100 switch.

    Flaky ethernet on SE/30

    Update: So Uniserver has recapped all parts of the SE/30, but still no joy. We recapped the motherboard, the analog board, the power supply, the ethernet card (and it's daughter card) and the accelerator card. But the SE/30 still acts the same way -- with no cards in it, it works fine. With ONLY the ethernet card installed, the computer can see the ethernet card, Open transport loads, and it can send a few packets - I've even printed using it. But trying to transfer a file just does not work. It starts the file transfer, and eventually just fails. When using the Asante troubleshooting tool, it reports random errors with the packets sent. When the ethernet card is installed WITH the accelerator card, the accelerator card works fine, but the SE/30 cannot see the ethernet card at all. Both cards worked well in the machine before any recapping was done, and I know that recapping was needed, but would it be possible that one of the new caps on the motherboard might be out of spec, and might be causing this? Tantalum caps. Any other ideas???

    Macintosh SE/30 without battery

    It was nicely done on the original Mac through the Plus. Had a nice outside door above the AC plug for the battery...

    Flaky ethernet on SE/30

    Thanks, but no -- 3' cable between SE/30 & hub - and it's a proven good cable.

    Flaky ethernet on SE/30

    I've seen that advice. It's plugged into an older 10Mbps hub that is then attached to a 10/100 switch... I've used this before, and the link lights on both the card and the hub look solid

    Flaky ethernet on SE/30

    Have an SE/30 that I had added an Diimo 030 accelerator board and an Asante MacCon ethernet card added in series into the PDS slot. I had lost sound, so I sent the logic & analog boards off to uniserver to have them recapped. I DID NOT send the power supply for recapping. Once I got the logic/analog cards back, I put the machine back together, and re-installed the add-on cards. With both add on cards back in the machine, the accelerator card seemed to work, but the ethernet card did not, not even getting a link light on the daughtercard (next to the RJ45). I pulled them both out, and put only the NIC back into the SE/30, and I got a link light... But when I tried to use the card, it would connect to the web, but downloading was sporadic... stalling often. Asante troubleshooting showed that the card was having errors about half the time. My question is: Could the power supply be causing this? Should I have the power supply re-capped? Or does it sound like some other issue -- maybe with the NIC? My guess is that maybe the power supply is weak, which is why the NIC would not work at all when the accelerator was in there with the NIC. Was wondering what any of you may think. Any advice would be appreciated. Should I have uniserver recap the PS? Are there chips on the NIC that need recapping??? Thanks in advance..
