Afternoon, Has anyone got any ideas on a data light problem that has appeared on my woz. Basically lights 19 - 27 inc' boards in that string all go out or do not come on from boot up, some times they do sometimes they dont, when they do come on , they go off after 2 minutes. all targets on said boards work with no errors showing up. I have reseated data cables back to the i/o board this worked for a week then went again. Any offers of advice welcome..?
