Hi,
I found a Sony HCD-DZ370's service manual. It might be same. SD detect is the s-master voltage descent under 15V (it must be 30V). If your amplifier hasn't got any short circuit, the error must be in the power supply. Probably one or more electrolytic capacitor have got big esr. If you have esr-meter check the capacitors, if you haven't you should change the electrolytic capacitors in the power supply for safety sake. If you're lucky, problem solved.
Üdv,
Oszi
