No Sound (2005 XJ8VP)

On my 05 XJ8VP with premium sound & navigation, I suddenly have no sound even though the head unit works fine. I have checked the fuse for the amp (good), but the amp doesn’t seem to be getting any power. The small fan on it is not running. I tried another amp & the same. HELP!

try removing the headunit fuse (from fusebox). Leave over night and reinsert
