I have soldered a little wire to C8's via, which seems to have done something to cause this problem, and it's not SimasiMac because there's no video, period. I mean NO VIDEO, as in no raster, no activity from the CRT, nothing. Just the startup bong, and then nothing else happens.
I know it's not the analog board/CRT, because I recently got another SE/30, and this same board had the same exact symptoms when installed in there.
The other one (I have two, hence this topic's title) is in worse shape, so I'm not even going to bother with it until I get this one figured out. What I learn with this one will most likely apply to the other one also.
I do have a couple of questions I would like answered: First, would sticking a wire through a via and soldering it there (a naive mistake on my part) cause this kind of problem? If so, is there a way to fix it?
I hope I can get this figured out, because I kind of like this machine.
And also thank you for your "success" photo! I aspire to do such things, but I don't quite have the experience, yet. I did try it on the newest SE/30 (I got it for Christmas) however, and, fortunately, it was a success as well. It was a very satisfying experience!
I look forward to your reply.
p.s. I will post a picture of this "sick" board when I learn to put pictures in here (I am new to this whole forum thing).
