Kou" Subject: 2nd SUMMARY on 4/280 problem To: suns-at-home@harbor.ecn.purdue.edu, sun-managers@eecs.nwu.edu Hi, Our problem with a Sun 4/280 server started after the Northridge earthquake. The problem appeared to be with the memory board(s) or the MMU at first since the server would work for a few minutes at first then it would just shut itself off; i.e., no activities on the CPU LED. As if the power has been turned off. However, it is not the case, since everything else is on; i.e., disk drives, all the fans(including the power supply's fan)and the power switch light(the power switch "knob" has a light so it acts as a power indicator) is on too. [Lengthy tale of woe deleted. Much of it is in the archives if you want] [to see all that Roger went through until he figured this one out. --ed] So we voltmetered the 5V. And guess what. The 5V comes and goes at random. And when it goes, the machine dies. I talked our our local Computing Services support staff about our discovery. He told me that it's very unlikely that would happen; i.e., only part of the power supply fail. It's either all or nothing, usually. But guess what, it happened. To confirm this, we loan a power supply from him. And the problem goes away. So finally last week, we ordered a power supply for it. And it's working fine now. We think that it's a heat problem. Although, not because of a fan problem. We think some capacitors in the power supply are damaged. Although only marginally. (we took the power supply apart, and didn't see the tell-tell sign of a blown capacitor: black top on the capacitors) So when the capacitors heats up, they failed to absord charges; hence, power dies. And the machine crashes. But when they cool down, they would work again. Anyhow, I hope this can help someone who might have the same problem as we had. I guess the moral of the story is that: 1) always check the least expensive item for fault(best case) 2) always check with your local people for resource and help first before you go for outside assistance(usulay cost $$$), get a loaner from your local people(usualy free) and test the components in question(voltmeter it or something) best, -RK ------------------------------ Date: Mon, 21 Feb 1994 16:17:58 -0500 (EST) From: hkatz@NUCMED.MED.NYU.EDU (Henry Katz) Subject: RGB potentiometers on GDM-1955 color monitor To: Suns-at-Home@ecn.purdue.edu Could any one please send me a little schematic as to where the color pots for this monitor are located.

My approach is just to power down the whole system, wait a while, and then power up. This has always worked for me (so far!). Unfortunately, I don't have any more technical solutions, but if you find one, please post it.
