This doesn't make sense, since there is only one laser-sled assembly, and the carousel just rotates until the requested
disc is over that assembly.
Any ideas?
Have you taken the top cover off the player and checked the mechanical operation? Perhaps it is not really rotating or clamping the other discs? If that is the case, I'd be thinking towards belts, assuming that the CD's are in good condition.

Yesterday, I put a CD in just tray #2. The player checked tray 1,
and about a few seconds later rotated and checked for disc min tray 2, scanned, and I got TOC(table of contents - total time, number of tracks),
and played when I pressed play.
_____Where the problems crop mup is when I have two or more discs in
the carousel. If I press the button for, IE disc #3, The machine will stop playing
disc #1, rotate to #3, scan, not detect the disc, and move on to tray #4, all
the way back to #1.
So basically, the trouble occurs only if I have more than one CD in the carousel, or press one of the five direct access disc #s.

Rule out disks - take known readable disk in #2 and move to #3, take known readable disk in #1, move to #2, put new known readable disk in #1. Go through sequence 1 to 2, 2 to 3, and see what happens.
When the carousel reaches the 'bad position' does the system try to read the disk? e.g. sled move? etc.Change the loading belt. I suspect that the additional weight of the CDs causes the try to be misaligned at the other positions. There is little to no movement of the tray for disc 1.
Can you check the signal on the optical receiver?
Am trying to determine if it is a carousel positioning problem or player problem.

If the belt is getting slippery, it won't take much to make a difference. Try the belt as it is the cheapest option at this point.Where the problems crop mup is when I have two or more discs in

That's a thought. But really what is the weight to power ratio of the carousel mechanism for a few CDs? This Is why I keep buying up thes carousels at second hand thrift - so I can simply switch in a replacement when the other one goes.

Belts are known to lose their elasticity and become gummy in Sony carousels. I changed tons of those years ago. I don't know if Sony still sells the belts but you can buy a generic kit on ebay cheap. Depending on the model, there's either two or threebelts in the kit IIRC.
