There is something that very very few people have attended to do, in order to refocus the laser lens manually, with the laser adjustment screws, by try and check, or better with instrumentation. I started a thread once about this very subject, to see if I can fix my Panny Blu-ray player's laser lens all by myself.
I asked the question here @ ASR once, but no one knew anything about.
I also asked @ diyAudio, but without results, and if there's a place on the World Wide Web to ask technical audio questions it's there. ...Even from a laser lens used to read Blu-rays, and not only CDs and DVDs and SACDs. ...Audio/video.
I believe I even asked @ AVForum across the Atlantic ocean, and also @ Audioholics during the "tumultuous" years.
I'm not sure if I asked @ WBF in the past...(edit: yes I did, I checked earlier).
I did ask @ AVS though for certain; I had no positive responses. So I googled around and shared my own findings through some youtube videos to AVS members. I did not take the time yet to do it myself though, but I know that I will. It's quite simple to do for us, for me; I have nothing to lose because the player has been packed for several years now; so any attempt is better than no attempt @ all. I just have to take the time and experiment...
Let me see if I can relocate some...
Two, if you like your Oppo BR player, their technicians will certainly have the expertise and instrumentation to resuscitate its laser lens focus, for Blu-rays, DVDs and CDs. IMO hundred dollars is fair.
