20 Most Recent Sherwood RX-4109 Questions & Answers


I'm am not certain, but it could be a safety circuit that is tripping the power. It will require investigation of the power supply to determine if it is good. It seems to me unlikely that it is the switch itself to blame. I think it would be rare for the locking mechanism of the switch to act like that.

Main board fault. Shorted component/s at its audio output section circuit. Most common fault is with its audio output transistors. If any one of them get shorted [collector to emitter short]; this kind of fault can occur. Check 2SD1510 / 2SB2510 transistor pair at this section circuit for short. If found shorted, check all the other components related to these transistors and make sure that all are good; otherwise, the replaced transistor too will get damaged in no time.

Confirm that the audio balance is not set to the left but in the middle!

Swap speaker connections to make sure the problem doesn't follow the speaker indicating the wiring to the speaker or speaker is bad.

Need to confirm that the input to the selected device is OK. Swap input RCA Red and White connections from the source. If an optical confirm that the source balance if the setting is available is set to middle

On many upgrade receivers as this Sherwood there is a test feature that confirms with an audio beep the speaker balance and connections. Look for a "Test" button.

Beside swapping the speaker connections left to right swap the speakers between the A and B speakers. See image for connection detail.

Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.
