I have a set of 6.1 sony speakers (no sub-woofer) left by the previous owners. I hooked them up to the receiver and there was no sound at all. When I measured the impedance with a ohmmeter, the readings were 20-30 mega-ohms for all of them. Are these speakers broken?


Thanks for your help.

Did you test the receiver's speaker level output with a volt meter?

Not yet. Since the receiver was new, I assumed it was speakers' problem. But it's worth a try. I might have got a DOA one. What is the normal output level I should expect?

If they all read open, then you're doing something wrong, or they're all broken.
That's why I posted my question here. It would make more sense to me that only one or two speakers are not working. It's hard to believe that all of them are broken. But I could not figure out what went wrong. I hooked up the speakers to the receiver, turned on the receiver, switched the sources to the built-in FM radio (I also tried TV, connecting using HDMI), adjusted the volume, but did not hear anything. Was there anything else that I missed?

As in many cases the terms are used interchangeably by some. Obviously if the OP is using an ohmmeter he is looking at the DC resistance of the speakers and as many see the "8ohm" listing they assume it means resistance. Natural error.


I would suggest that the OP be sure to get a zero ohms reading between the meter leads FIRST, then with the meter set at the lowest scale, read the DC resistance across the coils. It is highly unlikely that all the speakers are smoked.

Well... you either have 6 bad speakers, a DOA receiver, improper connections or bad settings in the receiver. I suspect the last two.



When you tried the FM tuner, did you hook up an antenna? Most FM tuners auto mute with poor reception.


HDMI output from the TV? Probably not unless both the TV and receiver support ARC.


Does your TV have analog audio outputs (red/white)? If so, connect the receiver to test.


Reviewing the manual(s) may also be helpful.

Another question, and this is a stab in the dark, is there any sort of speaker selector/volume control device associated with this installation? It could be improperly configured, damaged, or disconnected - which could explain some of your problems.


Barring that, follow Gizmologist's advice, and then Ratman's advice.

Thank you all for your help! The problem has been solved. The speakers work well. It was the HDMI cable causing the problem. I used a HDMI cable to connect the TV and receiver (both supports ARC). There was no sound sent to the receiver from the TV. Somehow the FM signal was poor and I didn't get sound from the radio either. That's why I thought that speakers might be broken. Although some people claimed that ARC worked on any HDMI cable, it is not the case for me. After I used another HDMI cable (comes with my BDP-93) to connect the TV and the receiver, the problem was solved. The first cable I used is cheap but it works fine except for ARC.
