The Denon AVR-1507 switches off and power light blinks red. Its a cool unit and ventilated so no idea what the issue is. This happened when it was off over night. What is the solution. Manual says send to...
Before you send the unit to the service center, check the wiring. Make sure that the speaker wires don't have loose strands that are touching each other or touching the rear panel of the AVR-1507. Check all of the speaker wire connections for loose strands. Since the receiver is minimally used, you could try vacuuming out any dust from the interior of the unit. Note: if the receiver is still under warranty, opening the case to clean it will void your warranty.
If the problem persists, a service center is the best option unless you are very skilled at fixing electronics. Manuals Lib does have a service manual for the AVR-1707, AVR-1507 and other models. However, there is a notation that individual illustrations may not match the receiver being worked on. A Google search can lead you to this manual.
I hope this helps.
