Today I opened up my home theatre system to clean the lens on the DVD player with a cotton bud and some isopropyl alcohol as it was beginning to get a bit fussy about rental disks (which tend to be dirty). This was the first time I’ve had to clean it since replacing the whole DVD drive mechanism a while back. It should work with occasional cleaning for a few more months and then I’ll need to replace the whole optical drive again. Or get a new home theatre system.
This is what it looks like inside from when I replaced the drive mechanism.
New drive installed except for attaching the cables.
The old drive before it came out.
