Hi all, I have an iBook G3 Clamshell Tangerine that I just took apart and put back together with an SE (366MHz) logic board and an SSD. When I put it all back together, I get the boot chime just fine, but instead of seeing a Happy Mac (or, the ? Folder, since the drive is empty), I just see the blank screen that it usually appears with. I've tried holding Option to get a boot menu, or booting in to Open Firmware. but nothing seems to work. When I put a bootable CD into the drive, it spins up as if it's trying to boot from it, but nothing appears on the screen. All parts were working separately before I rebuilt it.

Any ideas what it could be? It seems unusual that I get the boot chime but nothing works after that, I'm not sure what that usually means. Thanks!
