RasterOps Clear Vue GS30 for me SE/30 died...any ideas why?

Recommended Posts

Hello all,

     A few weeks ago I had the good fortune to pick up a few SE/30's with video cards, including one with a RasterOps Clear Vue GS30.  So I put it into my main SE/30 to test it out.  It worked well for about a week, having the ability to display 256 shades of grey at 1024 x 768.  And then one day I heard what kind of sounded like a ticking sound, and then......nothing.  The video card no longer displays anything, and doesn't even show up in the monitors control panel anymore. 


Also note that the same mac still works fine with my RasterOps Colorboard 264.


     Is it possible that one of the clock oscillators is bad?  Or is their something else I should take a look at?


Thanks for any ideas that anybody has!

Welp, so far I replaced the 80mhz crystal, transistors, voltage reference, all of the electrolytic capacitors, and two muxes: the CD74ACT153E (below the 50mhz clock) and the 74HCT139n.  And after doing all of that, I got.....nothing.  Then i replaced the 50Mhz clock, and finally I got a something- a blue screen that barely displays anything.  But at least something is being displayed, and the card is once again showing up in the monitors control panel.  But as you can see from the pictures, it's still not really usable:

here is the screen trying to display a picture:






And the closing screen:




Anyone got any ideas as to what I'm doing wrong/what I should try next?  Thanks!
