Thanks guys What I'm thinking... As I've acquired some 5 players now...4 of them Pioneer..I'm thinking its worth me getting a Pioneer Ref disc. Then can attempt scope align/adjust the player (and other players as needed) ...with also the hope the process could hint me if something cannot be adjusted to spec. For ref Dug deep on the forum search and got one hit for the same issue with the same player - seems to mirror my issue with this 2290 (2090). [CLD-2090] Can't switch from analog to digital

Sometimes lack of TOC and lack of Digital Sound happen together. The player checks something as it’s spinning up and if it finds it before the disc hits full speed then you’ll have chapters and Digital Sound but if you have grip slippage or anything else isn’t right at the time the player will just do it’s best to play the disc Discovision style. Slippage will also kill DTS and, I think, VDNR. Sadly I don’t know much more about it myself. When you play CLV discs do you see crosstalk?

Service notes for this model say a defective spindle or (less likely in your situation) poor solder connections.
Since you have an oscilloscope, you can easily see what is going on. Play a CD and look for the eye pattern. It should be very clear (hopefully you have an analog scope- it is harder to see on digital)
If the eye pattern does not look clean, that could be an indicator that it has a defective spindle.
Digital audio is stored at the very beginning (0 to 2Mhz) of the frequency spectrum on laserdisc, before the analog audio (2.3Mhz CH1, 2.8Mhz CH2). This might provide some insight into why you get analog, but not digital. Thanks Again C++ ! Ive checked and both CLD-2090/2290 and the CLD-2590K players do use the same spindle VXM1046 ...for ref seems like a substitute is currently available from PacParts being VXA2107 I do have an analogue scope....I will be getting it out dusting it down and will have a look ...thankyou for the directions.!

If anything, if you can confirm the spindle is defective, I would try pulling it and taking a look inside before ordering a new one (or better yet a donor unit to pull one from). It could be something else. If eye pattern is good, you'll need take a look at the reference waveforms in the SM that could be related to EFM/DA.
