I have not had a lot of trouble with disc players but some.
After a lot of use my Revox CD player failed. This was an early player bought in 1984. I just put it away and bought a Marantz CD player which is still part of the system here. A member joined looking for one of those Revox players. The problem was the drawer motor had failed. I sourced the part from the retired Revox service manager, who still had two tucked away. So I repaired it, and sold it to the member for a good but fair price.
I had a Panasonic BDT220 fail. I had two of them, one in the family room at our lake home, the other at our Eagan townhome. One of the Lasers failed in the one at the lake. A new drive was available online so I bought one and installed it, but could not get it to work. Of course there was no service manual available. Anyhow I phoned Panasonic and they told me that for security reasons a code had to be entered. That is corporate BS of course. Anyhow I persuaded them to send me a code and instructions of what to do with it, and it worked. I still have these, and one is in our great room and the other in my storage pile.
I also have an Oppo player, it is a fairly early player. It is a BD-83. I was planning to use it in the AV room here, but it would only give a mauve picture via my Marantz 7705 and my LG OLED. So I moved it to the family room here were it still works with the older Marantz AVP 8801.
I already had the Panny BD9000. However that does not play SACDs, so I had to replace the OPPO in the AV room with a Sony top line player. Both the Panny and Sony had issues orionally, which got solved with firmware upgrades. Then I have a cheap Sony to play PAL discs of which I have number.
So that is my story with disc players. Overall nothing out of the ordinary, but two would not be working without my service interventions.
