Message-ID: <12163@skye.cs.ed.ac.uk> Date: 7 Jun 91 10:16:20 GMT Sender: nnews@cs.ed.ac.uk Reply-To: nick@lfcs.ed.ac.uk Organization: Sally Fowler Rat Pack Lines: 24 Any other SE/30 owners had the following problem? A sporadic flickering/jumping of the screen: the top and bottom few pixel rows of the screen suddenly stretch, and the stretched regions drift inward toward the centre and then out again. Reason I ask is that my machine has been doing this, off and on, for months. It's been in for fixing three times, this last time for over a week, and the engineers can't reproduce the problem. When I get it back I expect it'll behave for a few weeks and then start doing it again. The problem seems to be brought on by (internal) HD activity - might it be something to do with the power supply and/or my mains supply? I'll try a line conditioner to see if this has any effect. Just wanted to mention it in case anybody else has seen this symptom and can tell me it's not all in my imagination...
