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

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...

OK.  Without knowing what type of antenna that you have, get a cheap pair of rabbit ears antenna and connect it to the receiver.  You may need to get a connector ... UHF VHF FM 75-300 Ohm TV Antenna Adapter Matching Transformer (cost about $2).   If you $40 portable radio works, so should your receiver.  Try moving your receiver to a different room.
