Question about Marantz Audio Players & Recorders

Left channel static

I have a 2238B with static coming from the left speaker. It is present regardless of source and there is more when I adjust the volume or balance. It is present when there is no source signal as well. It goes away completely when I use mono. Any help would be greatly appreciated.

I have seen dirty switches or pots cause constant static. I would get some contact cleaner and try spraying it into all switches and pots, and work them to clean the contacts. Also, check to see if there is static in a low-level output such as the one for a tape recorder.

SOURCE: No right channel output

Feed the amp with the left channel preamp to the right channel input on amp and check output. If you get output from amp then pre amp nedds to be checked out if still no output then amp is suspect. Randy

It is most probably a dirty speaker protection relay. gently tap the relay(the one that engages shortly after turning the amp on) when the fault is occurring and see audio returns. This should ascertain the problem. Replace it if it is a sealed type, or if it has a "lid" you can get off, burnish the contacts with a white business card, and give it a spray with contact cleaner/lubricant. Good luck and a "fixYa" rating would be great for my profile :)

Hope it may help you;;

I have a marantz 2238b receiver and a magnasonic dvd 824-2. . where do I connect the cable to watch movies?


To play audio from your DVD player through the 2238b, you will need to hook the RCA left an right outputs from the DVD to the Aux IN on the back of the 2238b. Then you will need to power on the 2238b and place the selector switch to the Aux position. Lastly, adjust the volume to a level you are comfortable with and that should be it.

Thanks

How do you get the RX icon to turn off? The unit just has a contant fuzzy buzz.


RX represents "receive" This indication will be present whenever the speaker is producing audio. The "buzz" you're talking about is probably static, and is technically audio from the speaker. To silence the "buzz" adjust the squelch just until the speaker falls silent. The RX indication should be off at this point.

It is important to note that the squelch is designed to keep the speaker silent until a signal is detected. You adjust the squelch based on the level of static at a particular time and at a particular location. The static level may change depending on those variables. If you adjust the squelch well beyond the point that the speaker is silenced, you may not be able to hear transmissions or calls to you unless the caller's transmitter is physically close to you. This is why the squelch should be adjusted only until the static is stopped and the speaker is silenced.

I hope this helps and good luck!

I would recommend checking your speakers polarity ( + on the + - on the - ). Also check to make sure the wires are not touching each other where they connect to the speaker or amp. Also check your input connections if you are not using HDMI or Optical. Worst case is you have to send it in to get serviced. Hope this helps

If you have checked the speakers and wiring, the right channel has a audio driver or output problem, which explains the low volume, static, and distortion. A service technician will be required to fix the receiver so it will balance the left side.

Only get sound out of right side both a and b


Good day sir, Hi, your Philips receiver trouble can be any of the ff:
  1. your receiver left fuse is blown, check if it has a user fuse at the back. or
  2. your main IC amplifier for the left channel is bad. you need to replace that IC, but check first the wiring of the speakers.
  3. Check your receiver left speakers if it is producing a soft hum, to do this turn down the right channel, or adjusting the balance knob to the left, or simply remove the speaker connection of the right channel. place your ears on the left speaker as you adjust the volume up and down, do you hear a soft hum that goes up and down also? If yes the problem is on the source section before main amplification, usually the pre-amplifier stage, If you hear no hum at all. problem with the main left amplifier. The main amplifier is usually a single IC for both left and right channel, OR one IC amplifier for the left and one for the right, in both cases, replace the bad IC.

Left Channel does not work. Subwoofer and Right Channel work fine. The plug needs to be plugged into the brown jack on the front of the computer to work at all.


Sort of sounds like there's a PC in the mix.

Can you swap the left and right speakers to isolate the speaker from the source as the problem?

Have you tried switching the various plugs around to isolate if anything comes out to the Left Channel, ever or if any other speaker plugged in as the Left works at all? Turn the volume down and bring it up slowly at first because if you send Subwoofer programming to a speaker not designed for it you may damage it.

If nothing works when plugged in as the Left speaker, maybe the sound card is the problem. Resubmit a question with the source or the PC as the problem

Yamaha RX-V596 main rigth channel problem


The right or left (side) output channel has blown out. If it uses discrete transistors you'll have to replace two of them (one PNP and one NPN) along with several resistors that are part of the circuit (I'm guessing the static occurs on any input source).
Now , if the static happens only on certain input, then the problem should not be in your amp.

Terrible static on left side of all channels


Hi...

Unplug all the inputs to the amp.

Does the problem go away?

If its only the left sometimes, it sounds like the speaker selector switch or source selector switch needs a good cleaning with some de-oxit and a small brush

Monster MPA 5150SS


Might be a failing semiconductor component (usually an old transistor) in the amplifier's front end. This caused by the oxidation through the component legs or pin. I usually touch and move each transistor's body to exaggerate the noise. You can research also what kind of noise is it producing- intermittent, static, etc.
hope this helps..

Speaker problems


You've probably tried this, but when you do the channel test you can turn the volume up or down on whichever speaker is currently being tested (the static). Maybe your speakers have been adjusted somehow.
