Hi All, One of the professors on the floor has an SE/30 (w/ internal HD) with a peculiar problem... Upon plugging it in, and turning it on, the screen displays a checkboard-like pattern (looks like 4x4 pixel blocks, alternating black and white, with with a middle (vertical) band (1/3 the screen width) that has every other white block turned black. Now, I know that Diagnostic Sound Sampler was designed for the Mac II, but I figured this may help in this case, so read on... At the same time this very bizarre pattern appears, the "sour" chord plays, followed by three increasing tones. Digging out "Diagnostic Sound Sampler", I determined that the first chord is the "Failed Initial Hardware" sound, and the next three are the ones plaued for "Test Monitor". Now, the text that appears in Diagnostic Sound Sampler when you click in Test Monitor is "This sound indicates that the Macintosh II has entered the Test Monitor". It sounds like "Test Monitor" is some sort of mode that a technician can enter to do something (maybe test monitor consistancy?)... I don't know, I'm not a technician.... But, does _someone_ know what this means? Is it something repairable (like, "hit Option, Clover, Shift, Tab, Enter, and roll the mouse in counterclockwise circles while double-clicking to exit Test Monitor") Obviously, the CRT is fine (unless the display is supposed to be all white :-) )... Also, _there_is_no_other_sound_played before the 3 tones (which would indicate a RAM failure, if DSS is correct!). Please, Please, Please send me direct E-mail, since I have millions of newgroup articles to read, and won't get to the new ones until at least Monday!!! (Vacations are a bummer!)... I will summarize if I find a working solution, and post to the net...
