Replacing defective lens part in Sony s3700 blu-ray dvd player

Sony smart blu-ray dvd player s3700 had issues of not playing any dvds and we found a similar one and bought and replaced the dvd drive part of the other player and that simply fixed the fault. later on we opened the dvd part and found a small screw in it which was an easy fault to find and fix. the dvd drive is easy to open aswell.
