Well, if you are skilled enough to get the laser out to get the part number from it OR if you can obtain somehow the part number without taking it out, THEN if you buy a new laser AND send that to me I will replace that for you no problem, just pay for the return postage
I finished 5 year Uni and have 2 Diplomas in IT and microelectronics and electronics, but it stayed like that till today as a hobby. I do this all the time just for satisfaction really and to keep me in shape
Blurays, dvds, cdroms, whatever, its not a rocket since if you know what you are doing.
To change the bluray is less than 1hour taking it easy with no rush, but it doesnt really matter if this is dvd bluray or cd as they all are same, same design, just different lasers, but same shape and size.
CDrom, bluray, satnav, dvd, ps3, xbox, cdplayer, they all have same construction and function, press eject, place the cd, press load and job done.
If you like doing stuff your self you may even do it yourself, it really isn't difficult
