If no 3.3V (standby volts) available on power supply board that means power board is bad and need to be replaced. Please search/ google the power board part number###-##-####to get price info.

47/5000
I can replace sony APS-28A by SONY APS-254

Not sure what is 47/5000

Apparently both boards look similar but you may face fixing screw orientation problem and I would recommend to use the identical power board to avoid any complication/ safety issues.
