Made by Panasonic, used to work on them and one of the better made units.
Is the disc free to rotate after clamping? If so, more than likely you have a worn/bad laser pickup?--that was the number one problem with that generation of players. sometimes it would only play a CD?
It is not something for an average user to change. In order to do the tangential adjustment after pickup change, you need to have proper test disc/experience. |

Start with power supply voltages. Is raw B-Plus present? Stand-by source(s)? Switched sources?
