Question about Sherwood S-7100a Am/fm Stereo Receiver Very Good

1 Answer

Is there a way to repair my Sherwood S-7100A Stereo Receiver? The On-Off-volume dial switch does not click on or off. Could it be the fuse (which visually appears OK)? Or does the switch itself need replacing? Is there any one who can do this for me, or can I buy the part somewhere?

Your best bet is to find a tech who can repair it; it is possible. Or buy another one on ebay--it might be a cheaper fix. These receivers are among the sweetest-sounding ever made and are well worth fixing.

Hi,

After doing all this troubleshooting on your receiver, Check if master volume on the surround levels are too low. Adjust master and surround level.

There may aIso incorrect selection of the input source. Select the correct input source.

If after doing this the problem still continue, it means the sound ic in the receiver is damage. the sound ic brings out the sounds from the receiver. You will have to open the receiver to locate the sound ic in the receiver and use the multimeter to read capacitors and change the damage ones.

Thanks for using Fixya.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections as a root cause for intermittent shutdown.

I have a Sherwood audio/video stereo receiver S-277OR CP. Why would it work but not put any sound out?


Check speaker selection switch. If set properly then perhaps the amplifiers are blown - check for fuses that may be open.

Shut up stereo protect mode?


Protect mode is on because something in your speaker wiring is wrong, or you have a broken speaker, or it\'s too late and you already fried one or more of the amp\'s output transistors.



You gotta fix the problem. Not remove the safety guard and carry on with a busted machine.



Look for wires touching between the speaker terminals or on the backs of the speakers. If you done a half-ass job of wiring up then this is the most likely cause.



If you can\'t find bad/frayed wiring, then disconnect all the speakers out the back of the amp. Switch the amp on. Does it trip out? If no, that\'s good. Turn up the volume. Is it still okay? If yes, that\'s good. You haven\'t yet killed the output transistors. If it goes in to protect though, ut oh. It\'s Repair Shop Time.



If the amp is okay, then power off and add one speaker. Power on with the volume down. If it trips either at no volume or when you increase the sound, then you got a bad speaker and you just found it. Repeat the process, adding one speaker at a time. Make sure you put Vol to minimum and power off each time before adding the next speaker.

Does the sherwood rx 4105 receiver have analog or digital inputs


Unfortunately the RX-4105 is a stereo only receiver with only analog L/R inputs. You will have to find a stereo output & go in through one of the stereo inputs.

The loudness knob has suddenly stopped working. The knob just spins, won't turn on the receiver at all. Any ideas?


The knobs are usually connected to a potentiometer; basically a variable resistor circuit with a long shaft that the knob attaches to. The knob could be secured to the shaft with a plastic grommet, which can be stripped. It could be attached by a small screw on the knob, and tightening that would fix it. Or, it's possible that the potentiometer itself broke, and would need to be replaced.

If the "pot" is broken, a repair shop should be able to fix it for less than $50. If you're handy with tools, you can take the 7100A apart; hopefully read the specs from the potentiometer; and buy a new one. Replacing it shouldn't take more than a few screwdrivers, some pliers, and a soldering iron...

Good luck!

Hear sound but cant get any real volume even at full blast


I was playing around with my Sherwood RD 6513 and adjust the the output level to its maximum, amongst other settings. This limited my output on the amp to a maximum volume of 65 not 90+.. Anyway i pluged in the microphone and done another 'auto setup' of the volume levels and distances, and this allowed the volume to exceed 65 again!

Also if you have an external source such as a DVD player - i would assume you have already checked its output volume setting?

Sherwood rx4105


you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
