I've got a Yamaha RX-A3010 that's acting oddly - looking to see if there's anything obvious I can do to test or remediate before I try servicing it.
The receiver powers on, and displays on-screen through HDMI. Speaker output, though, is a problem. I wasn't able to hear any output through FL and FR until I started some of the steps below. I'm also seeing the "INFO" section display "PHONES" for output, despite no headphones present. I had a Denon once that developed a sticky headphone jack, so I tried plugging and unplugging a set of headphone (after digging for a 1/4" adapter) - no change in display or output. More troubleshooting steps:
- Getting a little more aggressive, I popped the top and unhooked the CB454 connector that carries HP signals. Power on; same display on Info.
- Firmware was 1.6; latest was 1.8, so I upgraded that. No change.
- Performed factory reset; no change.
- Since I had a USB drive out anyway for the firmware update, I dropped an MP3 on it and selected USB input. Nothing. However, upon powering down and powering back up, I hear a series of relay clicks (like, five or so, I think) and with the USB drive in place, I could hear output from the speakers -- very briefly. I'd hear like, one set of clicks, and a super-quick bit of music and then the music stopped with another set of clicks. This repeated through the sequence, but when the clicking is done, there's no sound.
- In the self-test menu, there's a white noise test and a 1k tone test where I can hear output through the speakers, but clicking is constant when running these tests.
Can you think of anything else I'm missing before boxing this up to try to find a repair shop?
