Hello to all. Allow me to get right to the point.
I have a Yamaha RX-V520 receiver that starts up, clicks and then shuts down after about 2 seconds.
- There are no loose or disconnected wires
- There is no visible damage to any components (including caps)
- The fuses are good
- There is no odd (burning) smell anywhere
I have included pics, video and the schematics of the unit to assist in the diagnoses.
From my very very limited understanding of electronics I think it might be one of the transformers, but I don't know.
In the photos and video I show the relay that clicks.
In video "1- Display" I push the power button twice and then I push simultaneously, Power Button, Input Mode, FM/AM and Tuning Mode.
When I press all 4 these messages pop up.
PS PRT : 094 B
PS PRT : 095 B
PS PRT : 096 B
Thanks in advance for any help anyone might offer.

Thanks Again for any help.
P.S. I will probably be posting this question in other electronic forums. I hope no one has any issues with this.
