Hi all, this is my first post here. I recently acquired my 1100U from a family friend, it plays nicely but only with certain discs. Initially thought it only liked “older” discs, like early 90s, but that has proven to be false. My latest copy of Led Zeppelin II remaster from 2015 works flawlessly. After some research I found that the laser might be looking for the first stripe of data in the wrong place, for some discs and not others. Can anyone confirm or deny this? I was told it’s simply the laser is bad, however on some discs it does play flawlessly.
