I have a denon dra 25 reciever that I bought new. I have not used it for a number of years. When I plug it in and turn it on nothing happens. The off/on switch has continuity. There is power going to the power transformer regardless of whether the power switch is on or off. The power transformer is not warm. There is power to both the switched and the unswitched outlets on the rear of the unit regardless of the position of the off/on switch. There is no output on any of the three pairs of wires coming from the power transformer. Help!!
John,
If you have a multi meter then unpug from mains supply.With meter
on "ohms" range check the following:-
Fuse F501 (and F502 if mult-voltage model)
yellow to white on mains transformer this should show some resistance.If you have a mult-voltage model check
brown to gray and orange to white. Both should show some resistance, if not your mains transformer has an open circuit primary winding.....
SOURCE: Denon DRA-435R: First, the "switched" outlet
from your description its should be the switch or a loss connection
if it doean not power on now it could be the fuse
if you can open the unit follow the power cord inside you should see a glass fuse look if its burn if its ok its better to take to service
