Strange video issue w/ SE/30

[Ralphieboy]

Hi again.

My SE/30 (as everybody knows) equipped with 128 Mb of RAM, ROMinator2, SCSI2SD, RJ45 ethernet card, Daystar PowerCache 33mhz, recapped and analog board checked is developing a strange video behavior.

Some “snow”, “noise”, “white interferences” appears quasi each time I use it (see video).

Usually I hit the machine on its side and the result is: a return to a normal video behavior or a totally plain white screen.

I first thought the problem came from the analog board but this one has been checked recently.

My conclusion: I am despaired (lol).

We had some different snow like artefacts some time ago that were related to UE8.

Can be Bolle, but hitting the casing on one side won't be able to solve the problem, even temporary.

The Logic board was recapped a couple of years ago, and the Analog board was checked a few weeks ago (some weak weldings, all of them were cleaned and welded back again, even the small board on the CRT's neck)

I will see when the SE/30 will be at home, problem is... i never managed to see the problem myself.

Bolle, that’s definitely not that kind of artifact.

I was wondering; I am a violin maker and my SE/30 sits on my workbench close to gouges, metallic tools and other ferric stuff.

Could it induce some kind of magnetic disturbance that can manifest itself in those artifacts I am experiencing?
