Hi all, I just got my first Laserdisc player, a nice condition old CLD 3070. I noticed it's asking me to remove the transit screw , however there is no transit screw. There are two holes in the back of the machine- there was a regular size screw of about 1" in there when I bought the machine. Even with that screw removed I'm still getting the message. The machine plays beautifully, I would just like to know what I have to do to get it to behave correctly. Thanks!
