Chosen Solution
I just replaced the laser in an old gc, and it’s moving, but the disk isn’t spinning up. Not sure if that was already happening or if it’s a new problem though. What can I try now?
Update: took it apart again to check for that solder ball, and now the disc spins, but the laser doesn’t turn on
Go back over the connections you disconnected and make sure they are all connected correctly.
Did you get rid of the solder that you need to take off?
