Hi,
Repairing a Sonos Amp - Diode D2 appears to be shorted.
Markings are LSC0665SD2. I believe it's Liteon Semiconductor, but I can't find a datasheet or exact match for it. I've attempted to use OnSemi FFSD0665B as a replacement but the power supply doesn't work properly - secondary is a 48v PSU, it comes up to around 40v then appears to reset (nothing gone bang!).
Closest "LSC" device I've found by name is LSC06065DW.... but the pinout is nothing like the FFSD0665B I've fitted...
Picture attached, any help appreciated.
