Is My Onkyo Receiver's Tuner Dead or Just Playing Posum?

No sound or a bad signal? Does it have a setting to mute weak signals? In that case none of the stations in your new location may pass the threshold. Anyway, I would not worry too much. These days internet radio is at least as good as FM, and a Chromecast Audio used with the TuneIn app will give you thousands of stations in often pretty good quality. Not as good as CD Red Book, depending on a station's bitrate, but on balance, and with different strengths and weaknesses, usually better than FM, which really is a pretty outdated compromise technology. We still have a good FM tuner in the main system, but to be honest it sits unused now that we use a Chromecast to stream internet radio (and from all over the world).

I'm getting silence -not static or "white noise" (both AM and FM). The Onkyo tech says the nature of the tuner is to give silence if it can't find a healthy signal. The tuning dial finds stations if I cycle up or down (never get a "stereo" lock, however).
Good idea using internet radio! I was hoping to get WFMT in Chicago (great classical radio) but I guess this will be on the internet.
Just doesn't make sense the tuner going out on a $1200 receiver (close to ten years old). Thanks for the help...

So it does have an automute if the signal is not strong enough. Next time you visit a friend or family member in a different location with known good FM reception, take it with you and see what you get there.
Or just move over to internet radio. Internet radio is not perfect, but neither is FM. The deficiencies are different and therefore hard to directly compare, but I think on balance for most internet stations with somewhat higher bitrates internet radio is now superior. And it is only getting better: with more bandwidth by the year, bitrates continue to go up. A Chromecast Audio is only $35, and the inbuilt DAC is more than good enough for internet radio.

It ain’t muted, is it? The outboard amp is on, right?

Its an analog source so every zone should receive anything the tuner captures.

Is it set ONLY to HD?

Ant connections tight?

On both ends? Ant & receiver? Winds and critters can unhook it from the ANT.

Only other thing I can think of is what band are you on?

My TX SR 805 has either 3 or 4 bands. 10 presets to each band. I forget as it only takes a minute of FM for me to remember why I quit listening to it.

Pressing the AM/FM or Tunner key…repeatedly , can’t recall which, but one for sure, until you reach the band where your presets are. Otherwise it will appear to be muted. Pulling in no channels. Or it can be done from the drop down panel on the front of the unit.

Sometimes I lay the remote down and a key gets pressed accidentally or something. Who knows.

Durect access us bt pushing the #8 or the key to the right of the zero, (_it says which on the remote itself) and then inputting the exact ch number. 99.5 = 9-9-5.

Anywho.. hope you try that and it helps. Or it magically returns to operating just fine.

Best…

I did a "factory reset" few days ago just to be sure some obscure option wasn't accidentally engaged. Checked most of your suggestions (blindjim) and the dang thing just doesn't work. I have the receiver set up next to my (brick) fireplace. Not sure which direction signal is from. Why does my $40 portable radio work and the Onkyo does not (if weak signals)? I'll just use internet radio...
