Right speaker does not work on both A and B - Technics SA-DX930 Receiver

Does the right front speaker need to work in order for the whole speaker system to work?

The whole system can still work with or without it.

Here is an additional tip how to ..... Computer Speakers

Adding on again: I have interchanged speakers, if i connect any speaker on the right front channel it will not work. When I do a automated speaker test only right front channel does work.

Let's name the product and use FM for troubleshooting. Are you saying you have the Right Front and both rear amp channels/speakers not working? What DOES work?

Reconnect all the wirings of the speaker set. Left and Right sound connectors from the subwoofer properly.

To locate the problem...a) Cable
Test if right cable is ok, by interchanging the rt/left cables.

b) Test Bose right speaker
Connect the Bose right speaker to HK's left channel. Works? Then Bose right speaker is ok.

c) Test HK's right output by connecting the left Bose speaker to HK's right output.
Does not work?

if u have experience with the soldering of the terminals then you can open the speaker casing of the sub woofer and then solder the right speaker input wire.

dont do this if you have no previous experience and DISCONNECT THE POWER SUPPLY before doing any work inside.

hallo i have N78 its right speaker not work now its dont work at that time when i play song at that time i masg i reseve that at that time right speaker not works plzzzzzzzzzzzzzzz answer me

1ST.-The right jack could be damaged!!
Usually, there is a [+} posaitve & [-] negative input\output to speaker connections. Not all [-]neg. is ground.Sometimes the [+] pos. is grounded. [The exception to the rule is that u SEE the black wire going to ground] the reason I am letting u know this is that u can test the INSIDES of the sound system.
If u can get inside of the unit. Cut the left speaker output [+] posative from both outputs. criss\cross wires.Place left speaker output to right speaker jack[ that does not work!!] & visa versa.If the [LEFT Output] stops working after u plug in the speakers,the internal RIGHT output is damaged. NEEDS TO BE TESTED
If nothing nothing changes.The left still works & the right still does not work, then it is the jack (shorted ?, opened internally ?)

Can you swap speakers and see if the left working speaker works when plugged into the right output?

If it does, then your right speaker is bad or the right speaker cable/plug may be bad.

If the working left speaker doesn't work on the right output, then I would suspect a problem in the right channel audio amplifier.

Please let me know if I can be of further assistance to you.

Good luck!
