Keywords: unixpc 3B1 boot Message-ID: <1056@ncar.ucar.edu> Date: 29 Nov 88 03:09:12 GMT Sender: news@ncar.ucar.edu Reply-To: sitongia@hao.ucar.edu (Leonard Sitongia) Distribution: na Organization: High Altitude Observatory Boulder, CO 80307 Lines: 29 System: 3B1, 2Mb RAM, 40Mb full-height disk With increasing frequency, my unixpc shows an intermittant problem in which it wont boot. The screen goes solid green (or bright green with a fine black grid that makes it look like an array of small boxes, but not like the line of small boxes at bootup). Usually this is upon powering up the box, but once it crashed with no messages and showed this symptom. In the past Ive tried the solutions to the "drive doesnt spin-up" problem, shaking the box and cycling the power. Eventually it is revived. Other symptoms are that the keycaps lock LED comes on briefly and the fan works. Since this problem has been occuring with increasing frequency, I sent it in to AT&T for repair. Unfortunately, they want to replace the motherboard and some other board, at a cost of $1400! That's what I spent for it new! So, Im going to have to try fixing it myself. Can you give me a hint on what part of the hardware may be at fault? Is the green-screen consistant with the "drive doesnt spin-up" problem? Sure seems to me that this could be as simple as a loose cable or bad solder connection... Thanks for your help, Leonard -Leonard E.
