Optical drive no power

maybe you nicked a cable going to the drive , or its a software issue

Most laser assemblies ship with a shorting solder connection on the ribbon cable to prevent static damage. Look carefully at the cable on the optics assembly itself for a small “bubble” of solder. Remove this and the laser should work. Since the assembly won’t attempt to spin the disk unless one is detected (laser lights and detects the reflection if a disk is there), it may appear that the assembly has no power. Check for the short and update this with what you find. If you can, post a few pix of the assembly from different angles too.
