Do you suppose it needs to load the operating system from the cd disc before anything more?
Does the cd drive spin if you have a disc in the drive?

Thanks for posting pics,etc.
There are so many great product ideas in all fields of endeavor that didn't make it in the market ,sometimes for reasons unrelated to the product's merits.Usually it is lack of marketing or other capital shortages.

I'm inspired to dig out my CDTV.

Maybe one of the CD32s as well.

YOu didn't happen to find any SX32 in that stash?

I'd guess CK means ClocK  and is low voltage 60 cps so the system can sync the video to your tv .

SF MIGHT be "signal from" or SaFe ,or ?,something that tells the power supply its OK to send power.

Put an oscilloscope probe there to be sure.

There also has to a ground or return lead or trace.
I'm also wondering if there isn't a +12vdc .
5vdc is standard TTL IC power supply voltage/
CMOS ICs often use both +12 and -12vdc(which can be derived from a 9vac source .

If the electrolytic  capacitors leak the goo is generally crumbly white and nasty;many assemblers evidently glue the larger capacitors to the boards.I have no idea why.
