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.

Hello
thanks
but I already have the service manual of this unit.
I wonder if anyone can help me for repair.
I think it's a power problem

Thanks

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