Yamaha CR-2020 suddenly stopped working

Just turned on my integrated amp and it turns on but no sound. There was a brief very low sound of the record playing but then no sound. Changed speakers still nothing. Tried another amp and the speakers work. Headphone plug has no sound as well. All features light up but no sound. Help please.
 
That is what I was thinking. The new unit had work on it about 18 months ago but not to the power supply board.
