Question about Harman Kardon AVR 225 Receiver

1 Answer

AM/FM receiver The radio is not functioning properly intermittently. I can some times receive both AM and FM, but sometimes only AM, sometimes nothing at all. There is never any additional static that would be normal. All other source inputs work fine. When I can receive the AM only, I cannot change the station. The display will change when I push the tuning button to another station, and the display will switch to FM when I push that button as well, but the tuner will not change from the initial station.

I can get am station fine get fm barely

The FM and AM antennas are different types. AM sometimes doesn't even need an antenna. Please make sure you are using the right type of antenna attached to the FM antenna terminals on the back of your receiver. Usually a 6-8 ft. piece of wire is sufficient if you're within 20-30 miles of a radio station.

My radio reception is intermittent

Check your antenna and antenna cable. Many devices has switching power supplies with can interfere with the receiver like a computer, laptop, dect home phone, printers, fax etc. Also could be something outside like rf tower. you may try other receiver/fm tuner to see if it has the same recption problems. If you find that your receiver is no good you need to replace internal FM tuner.

FM antenna is not providing reception, despite cable connected to powered antenna amplifier. TV also connected to powered antenna amplifier (splitter) works fine. FM mode produces only static. I purchased...

If I understand your setup, you've connected the receiver antenna terminal to the output of the antenna amplifier. If this is true, I'd suggest trying the receiver using a plain old FM dipole antenna (available at Radio Shack and other stores) or even just a piece of wire hooked to the antenna terminal. You should be able to pick up some local FM stations then.

What might be happening is that the FM is being filtered out by the amplifier. Some amps made mainly as a TV signal booster have an FM trap designed to block the FM broadcast band. In the analog broadcast days, the FM band was right near the sound part of a TV signal, and the trap was there to prevent interference. It may be filtering out your FM band.It may also be possible that you're just overloading the FM antenna input with the amplified signal. Sometimes a signal can be too strong. Using a simple wire antenna will let you test the receiver by itself.

Other than connecting an antenna you shouldn't have to do any setup for FM reception. If you still get no stations at all when using a simple antenna, then the receiver may need service. But I doubt Circuit City would have sold a floor model that was defective, even at the very end, unless it was clearly marked as such and sold "as-is". I'm pretty sure you'll find that the receiver works with an antenna made for FM.

Hi, My LG Home stereo posibly experienced a small power surge (all clocks in house were blinking) and now has defaulted to some odd functions and will not receive radio stations or transfer sound to the...

This definitely was as a result of a power surge but the type of power surge seems irregular you should report the surge to the authorities.
Then as regards the radio defaulting to odd functions most likely the function which your unit defaulted to are the functions with which the unit was shipped from the factory. Usually the settings just have to be made and your unit is back to normal function the advised settings can be found in your user manual.
If after setting the unit still does not receive radio then the surge must have damaged the FM receiver console inside the unit and this will have to be replaced by an expert.
Hope this solution has been helpful?

How do I preset the tuner for radio stations. I've never had a problem doing this with any other stereo. But what I think should work isn't!

Not very specific. Do you have the manual?

The following is from a VSX-03TXH manual. It ain't pretty but it may help.

I'm posting it in multiple parts due to space contraints.


Chapter 6:

Using the tuner

Listening to the radio

The following steps show you how to tune in to FM and

AM radio broadcasts using the automatic (search) and

manual (step) tuning functions. If you already know the

frequency of the station you want, see Tuning directly to a

station below. Once you are tuned to a station you can

memorize the frequency for recall later-see Saving

station presets below for more on how to do this.

1 Press the FM/AM button to select the tuner.

2 Use the FM/AM button to change the band (FM or

AM), if necessary.

Each press switches the band between FM and AM.

3 Tune to a station.

There are three ways to do this:

Automatic tuning

To search for stations in the currently selected band,

press and hold TUNE ?©/?? for about a second. The

receiver will start searching for the next station,

stopping when it has found one. Repeat to search for

other stations.

Manual tuning

To change the frequency one step at a time, press

TUNE ?©/??.

High speed tuning

Press and hold TUNE ?©/?? for high speed tuning.

Release the button at the frequency you want.

Improving FM stereo sound

If the TUNED or STEREO indicators don't light when

tuning to an FM station because the signal is weak, press

the MPX button to switch the receiver into mono

reception mode. This should improve the sound quality

and allow you to enjoy the broadcast.

Using Neural THX

This feature uses Neural Surround™, THX® technology to

achieve optimal surround sound from FM radio.

• While listening to FM radio, press AUTO/DIRECT for
Neural THX listening.

It IS an airborne signal so you can expect it to be affected by the antenna and other electromagnetic interference. Most FM tuners have a selector for how aggressively they accept or reject a marginal signal. Perhaps yours is crossing that threshold periodically.

No volume in TV sound. I have volume in both FM radio, and CD modes.

I presume you mean no audio whatsoever from the TV as a source... If you have the Audio Out of your TV connected with an RCA jack pair to TV Sound In (or any other source EXCEPT Phono) and you properly select that source AND your TV is configured to output its sound to that path, you should have something audible. Perhaps your TV is set to Mute the output when using its own speakers or something like that. My guess is the problem is external to the receiver.

Try connecting something else to the TV input on the receiver to prove or disprove its function.

Tuner Omits No Sound - Onkyo TX-SR605 7.1 Channels Receiver

Make sure your receiver is hooked up to proper AM and FM antennae. Try switching to AM, scan stations. If you hear AM static and/or weak signals the problem could be antennas are not hooked up. FM has AFT which blocks out weak or noisey stations and you wont hear anything without ant.
