Much easier to replace the whole transport/laser than just the laser.
4 screws, a push on power plug and push on ribbon connector.
I’m fairly sure it uses the old DSL-710A laser/mech complete, which are cheap to buy new still under $100, take the top off yours and see if it’s like this

If you can use a screwdriver your almost there, should take 30-45mins, maybe 1hr if your slow.
