Question about Sony Audio Players & Recorders
I have a Sony receiver STR-D985that is about 15 years old. My main receiver for my sound system, (6 sets of speakers, with a Niles HPS speaker selector connected to them). Worked great for a few days, then I inadvertantly deselected the ''protection'' button on the speaker selector, meaning I was powering probably 2 ohms... and the receiver got really hot and turned off. I waited an hour, and tried turning it back on. The red ''power'' lightcomes on, but no sound, and the digital display is completely blank. Is it possible there is afuse in the unit that blew, or it is unfixable? Which not incidently, is EXACTLY what the JVC receiver that WAS powering the system did.. got really hot, then no sound. When you turn the unit on, you get the red power light, but no digital display.
As a quick test,plug in a 1/4" headphones and tune for tuner radio signal.
I hope you can tune in on a station and check for sound quality.
As long as you are able to tune in on a station and able to listen it will be fine.
The power amp for your Sony STR-D985 is a MOSFET amp.
I would open up the casing and re-grease (White Lithium) the heatsink contact grease first.
Disconnect the Niles speak selector and connect the unit with direct speakers connection.
Please let me know after you do a test with headphone and direct speaker connection..
