Weird Problem With Power. Pioneer D503s

I own a Pioneer receiver VSX-D503S. When you push power button it has no power. I opened it and checked all fuses. It seems like they are good but for some reason power does not get to the transformer or out of it.Please can anyone help?? Thank you

Re: Weird Problem With Power. Pioneer D503s

This unit has a standby supply with a separate, small transformer on the PC board. Check T751, D752, C752, and R752 first. You can find the schematic at the bottom right corner of page 15 of the manual available on this site. I am assuming the standby indicator on the front panel doesn't illuminate???
