Hi to All,
Hi Mbates14,
Found this illustration of the Sony CX22011 PWR control IC in my archives.
Unfortunately, spec sheet searches yield nothing and i've never had a full Sony data sheet, even in 2007.
Also, there is no Theory of Operation in the KVX-370 Service Manual so it's going to be a difficult task to assess what voltages & how many the CX22011 supplies.
Note: this parts search co. claims/MAY have a spec sheet but requires inscription (which i won't do):

Sorry! not to be more helpful,
Best Regards
