The picture (http://ajgelado.eresmas.net/shots/pict1814.jpg) shows a series of ordered horizontal scan lines of regular width, so I think the analogue board (with its horizontal and vertical sweep circuits) is working correctly. It must be a logic board problem. I'd try the standard procedure: to take out of the logic board all the SIMMs (both RAM and ROM, if it's present), cleaning its edges with a pencil erarser and reseating them. If you have known-good RAM SIMMs at hand, you could also try them.
I'd also try to power on the SE/30 with both the hard drive and the disk drive unconnected from both the logic board and the power. If you get a bogn and then a flashing disk, you know that the problem is in one of the drives (or their controllers). If nothing solve the problem, I'd try to adjust the analogue board's voltage regulator. If you need further instructions on how to do this, I can give them to you. In the worst case, there's a (small) posibility that you have touched the logic board while being charged with static electricity, and that have "fried" one or more chips. In that case, the only possible fix would be to get a replacement motherboard. Good luck!
