LC 475 - Bomb with X below?
Posted by: arroz on 2026-05-13 06:18:51
Hi,

I'm eyeing a 475 being sold online. The owner says he sold the monitor already, and the Mac is broken, as it showed a bomb. I asked (with screenshots) if it was the system error bomb or a sad mac, but he says it shows a "little round bomb and an X below".

In all my years of using Macs since the Plus, I have never seen this. Is this something specific to the LC 475? I'm trying to figure out if it's just a bad OS on a good Mac, or a HW issue on the logic board.

Thank you,

Miguel Arroz

if I had to guess... it's bombing at the welcome to macintosh screen, and the X is a system extension that didn't load.

Well, I ended up buying it. We'll see!

And I got it. It seems to work! HD and fan are dead, speaker is a bit messed up but the logic board and PSU appear to be fine (all the voltages have acceptable values when load is present). Haven't tested the FDD yet. I just can't see the actual video out, since I thought I had the right adapter but I don't. But if I plug a SCSI disk with I believe 7.1 installed, it starts loading the OS from it after the chime, so, success! 😁
