It can be fixed by yourself. All you need is some tuner lubricant (available at Radioshack or similar store, or if nowhere can be found you can even try WD40). Pull the knob off so you can see the shaft. Spray the tuner lube onto the shaft (let gravity be your assistant). Replace knob and work it back and forth until it moves more easily than before. Test it and you should be golden.

There is a crackle when i turn the volume knob.


First unplug it. Sounds like you need to spray some tuner cleaner in the pots that are crackling. Pull the knob off and you should be able to use a spray can of tuner cleaner with the straw that comes with them to spray into the potentiometer , then rotate the pot several times while it is still wet. After cleaning them all, wait 10 minutes and then try.

Mackie 450, signal light off, Sound only comes out when amp. turned up above 75%, when usually used at 40-50%. too loud at 75% and UP, does not Work at ALL below 75%. only 2 years old, with 25 uses... i...


Doesn't sound like a fuse. They don't fix themselves when you reach 75%.

Try shaking the volume knob while in the 30-50% range and/or try (with the power off) rotating the volume knob numerous times from 0% to 100%. If when you plug it back in it responds ANY differently, you might have a bad volume potentiometer. If when you shake the knob you hear static or intermittent sound, you have a bad volume pot.

The only other thing I can think of is that the wiper of the volume pot is not in contact with the windings inside the pot until you reach the 75% mark. When the volume comes on at 75%, does it start off kind of "static" then come in loud and clear? Also try this.... adjust the volume pot to 74% (or when the sound just begins to come on). At this point shake the knob. If you hear static, replace the volume pot.

Unplugging it when still on shouldn't cause any damage... in fact it probably hasn't considering it works at 75% plus.

BUZZING WITH NO SOUND


The audio outputs in the receiver are bad, and will need to be replaced.

I have a marantz sr4320 receiver. The volume control knob is not working---I can't get any sound no matter the volume number. "d8" is now showing, too, following the number. I have followed...


Do you mean "db"?

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING. The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Turn the volume down.

While you're squinting at the front panel, find the manual and evaluate every indicator on the face to make sure you understand what they mean and how they might affect operations. Look for Speakers NOT enabled, Muting ON, a Tape or other input inadvertantly selected. If you fail to find the errant setting, treat it like a new install and set it up all over again according to the manual.

Can I replace the stock power cord on my Marantz PM-11S1 integrated amp. with a new high end power cord ?


Hi Nancy,
Yes you can replace the power cord if it is already defective(open internal wire). You may buy on your local electronics store. But if the power cord is in good condition, there's no reason to replace.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Sound from my turntable started going.sounded like a big pile of fluff on it but. changed the cartridge (AT95E). still have the problem plugged it into the aux on amp (marantz pm-44se)sounds ok but have to...


AUX does not have enough gain for a pick up, it will never have volume. Use the proper (phonograph/main/turntable/preamp) input. Check the wiring from the stylus arm all the way to the RCA plugs, one of them might be shorting, or broken. Just test for continuity from the cartridge receptacle to the RCA plug. Turntables have very little sound components to go wrong.

the input selector switches if they are dirty can make the amplifier sound like it has a blown channel.
compare voltages from the left and right channel and make sure they are identical as well as the power supply,typically + and - 65vdc .check the regulators for the pream,they run panel lights off the same circuit + - 14vdc

No output from left channel after crackling sound


Marantz SR 5200/6200 lost audio or crackling on left or right channel except in mode s-direct is now fixed !
The root cause is a defective inegrated circuit on DSP board (the one with digital inputs). To fix it change the chip CS4391 by a new one or better by the improved version CS4392. On my device a capacitor was cut close to this IC : replace one 1uF after changing the IC. For any question search me with my callsing "F5RCT"; i have a spare IC for the one who is able to change it !
I'm amateur radio and engineer
