Pioneer cd/cdv/ld player model CLD M301 information?

Just got a Pioneer cd/cdv/ld player model CLD-M301

The cd's play well,
But the Laser Discs will play fine for a while (like 3 to 6mins)
Then the LD's will skip and then just stop playing. The display lights will dim and I can hear it trying to spin up. The skip or FF buttons dont work while this is happening just the stop button. But if I hit play it will start up just fine and it will happen again in a few min's. So.......

Are there adjustments or cleanings than can be made, How much does adjustment and/or cleaning service cost?
Is it worth my while with this unit?
Also looking for a user/owner manual for a Pioneer VSX-9700s?????

Thank You, Maxx
