After "marrying" two partial SEs to form one complete machine, I am now trying to troubleshoot the result.
It powers up but there is no startup chime and the screen is a checkerboard pattern. In searching for a solution, one suggestion I found was to remove the RAM and ROM, clean the connections and re-install. I don't have a tool for removing the ROMs, but I did remove, clean and re-install the RAM. It didn't make a difference.
One possibility is that the ROM connections need to be cleaned, but I am not sure how to remove them without an appropriate tool. For what it's worth, they look clean and are firmly seated.
Another possibility is that the RAM is bad. I don't have a working SE to pull RAM from to try. What other models would have comparable RAM? I do have an SE/30 that, until this afternoon when it decided to give out, was working and presumably has good RAM.
And, if it's not the RAM, what else could it be?
