There is a capacitor C493 that is 1000uf 16V on the mainboard that seems to go bad in 703 and 704 units. It is the largest capacitor toward the front. It will also blow the ICP-N5 fuse on the board closer the the outside. This powers a video IC and some other stuff that is not used when playing CD’s. CD playback only requires the digital audio section to track the CD. LD requires the video signal path to track. You only see this problem playing LD’s.

This scenario is only valid when CD’s play fine and LD’s spin up but never lock in and play.
