Anyone with a working Quadra LC 630, Performa 6200-6300?

Hi,

Can someone with a working Quadra LC 630 or Performa 6200-6300, please tell me if it will still post without the front LED/infrared/volume control unit plugged in?
I just wonder if mine has developed a fault.

Thanks.

oh wow, my 637CD, 6214CD, and 6300CD all have their original caps (to my knowledge with the 6214 and 6300)

Thanks a lot for that. I was hoping for an easy fix but, it looks like the failure is with the main logic board.

I have a spare logic board you can have. Just pay shipping. Even recapped. In canada

speaking of spare things, got any spare 68040s? I want a full 68040, not an LC or EC, 33MHz or higher

Thanks for the kind offer, I actually managed to get this going now. It turns out there was some corrosion on the contacts of the Cache Rom slot which I didn't initially see. This slot sits directly below the fan/enclosure, which had a bit of rust on it, so might explain where the moisture came from.
I sprayed some contact cleaner on the slot and inserted/removed some thick cardboard 30+ times which seems to have cleaned it up. Now the machine posts.
