I had a friend of mine tried to replace some of mine on a CD player. Well let me Telya it wasn’t that easy just to get the glass front off was a project and then the bulbs were soldered to a circuit board with other circuits on it and I think we overheated the board because nothing ever work the same again. LOL I sold it to the Macintosh dealer letting him know what we happened I’m sure a service tech knew how to fix it but I just gave up on it. It was about a $700 mistake lol
