As you can see in the video I will post a link to I had a Samsung dvd-n501 that had a disc error, then it just would not stay closed, it just acted like there was no disc there at all. After some reading here and digging up service manuals I decided on a Samsung dvd-m101 as a donor dvd player to try a swap out. The 2 service manuals showed identical parts list on the drive. I found the drive looked identical when I got it, so me and jy son attempted the swap. Really simple. I don't really do tutorials so I just recorded the process and added some info to the video through text screens. I sped up the repair part so it would not be so long. Me using a screwdriver is boring. lol. Whole process took 20 minutes. I want to say I had to remove around 6 screws from each machine anda couple wire connections. I actually removed more wires than I needed too, but it made things easy to deal with. The thing works perfectly. dvd-m101 andc dvd-m102 dvd players seem reasonable cheap so are good models to chose when doing a swap. Back to being able to play Tempest on this machine. Youtube video.
