Dead tweeters?

[stevo1210]

I just got this one off a friend today. It's a Sony BH-850CD mini HIFI system probably from the late 1990s. Everything works on there except CD. I don't really care about CD because I'm using the AUX line for computer speakers. The system has mediocre sound quality, that I am ok with for now. What I don't get is why the mid range and the tweeters of both speakers don't work?! I've tried pressing the buttons S-sub and DBSS and it hasn't changed anything. The speaker cables are the standard average joe red and black cable, there's no other special data cable or fancy crap like that.
This unit was dormant for a few years in a lounge room and was covered with dust.
Anyway, is there any way to get the mid range and tweeter working again? For now, I can only hear sound come out of the big speaker at the bottom of each speaker unit.

Thanks.

Can't find any mini stereo named BH-850CD: are you sure the name is correct?
Anyway, have you checked for oxidized/fake contacts and bad solderings? Is your computer volume high enough?

Sorry, my bad. The model is FH-B50CD. I was very dizzy yesterday whilst writing the post so that may play a part in my misidentification. At the moment, I am diagnosed with some crappy virus in my ear that alters my balance and makes me dizzy.

At the moment, I am using extension cables to extend the length of the audio cables. But even without the extension cables, the tweeters and mid range don't work. I can't get to those speakers because it is a sealed sepaker box unit. And my computers volume is up on full. And I also turned the volume on the hifi system to 50%+, but I still don't see any changes.

Thanks.

Sorry for your ear: sometimes my right ear's eustachian tube gets filled with mucus and this feels like listening to a mono record on the left channel with headphones. It drove me crazy the first time I got it ...

I think there are issues with the amp or the crossovers inside the speakers: if you have another pair of speaker, try connecting them to your Sony ministereo to diagnose which is the culprit. If you can use another amp, test those mini speakers too.
