"Valid DVD Drive could not be found"

[JohnBH]

I tried to upgrade my tibook, g4 867, OS X 10.4 with a superdrive to replace the cdr, dvd rom, and something went wrong. When I installed the new drive, and restarted, the drive would not work, and the trackpad would not work. I re-installed the old drive, and it would not work, and there was no sound. Also, the time and date had gone screwy, and I had to reset that. I reset the PMU and the PRAM, but I had no sound unless I disconnected the optical drive from the logic board, and the trackpad would not work, even though I rechecked the connectors. The time and date have stayed OK.

I figured that I had somehow damaged something, but was willing to work with a USB mouse, and a USB DVD drive. The mouse works, but the drive will not. When I connect it and load a DVD Disk, DVD Player comes up, but then I get a messsage that "a Valid DVD drive Could not be found" The drive will work with music CDs.
Do you have any idea what may have happened, and what I could do to fix this?

PowerBooks have small, ribbon connectors which link the motherboard to the disk drive, trackpad, and I believe the clock battery as well. Make sure these connections are firm - you have to pull the latch up from the port, put the ribbon in, and push the latch down. Also, make sure there are no empty ports.

Hi Eric, thanks - Yeah, I checked all the connectors, but that doesn't seem to be the problem. I had to leave the optical drive disconnected, or I don't get any sound for some reason, but since the drive doesn't work anyway...

I'm kind of stumped, so any ideas are welcome!

Also did you follow the setup/install guide at iFixIt.com?

Hi, and thanks, but yes I did follow same procedure. I think maybe I damaged the logic board somehow, because too many things went wrong. Anyway, I'm still working on it.
