I have an Onkyo Integra Home Theater Receiver that refuses to power up at all. The model number is DTR-7.1. I have done at least the very basic task of trying different power cords (it uses a computer style heavy 3 prong cord) but has no ground wire in it to the outlet.
There is no smell of burnt components even after taking the cover off. It was plugged into a UPS during its life so that should have taken care of most, not all surges and conditioned the power going into it.
Visual inspection of the unit does not show any signs of melted or discolored PCB's. I have found 3 fuses that "look" good but I am going to replace anyway.
I am not so much as getting light from the little red led showing that it is getting power from the wall, let alone anything when pressing the power button.
I just got my first DMM and would like to know how to do some basic tests on the power switch (to make sure its working) or the components between the plug in the back of the unit to the power switch to see if anything has failed.
I am hoping this is a simple fix because I hate to throw the unit out for something stupid that could easily be fixed.
This is a link to the manufacturer's page about the device:
