Beolab 7-2 thermal protection issue

[Senyo Heimann]

Got a used beolab 7-2, as suspected from its 30€ listing price it didn’t work. The diode under the rubber cap in the back of the unit shows a red light when plugged in, then switches to orange immediately when power link cable is connected. So I measured the resistance of all the speakers, and found that one tweeter showed a 0 ohm reading. This would likely be the culprit- but as this is a very low cost situation I would like to verify this before ordering a new tweeter. The orange light persists when the tweeter is removed- I am not sure if this is normal- or if the unit should be able to turn on without a tweeter connected.

I am not very savvy when it comes to electronics, so forgive me if I am making any obvious mistakes- but if anyone has some advice that could help me confirm that the the tweeter is not a secondary casualty to a bigger problem it would be greatly appreciated.

Aaight. Nobody answered (in 24 hrs) which is not really something to complain about. But for the sake of internet searches and troubleshooting on this issue in the future I find it pretty antisocial not to post the fix to my initial issue.

So-

The tweeter had shorted- measuring at 0 ohms. (Real bad ChatGPT told me, when I was super specific about the problem) but the thing is- the thermal protection light will stay on- (orange light=paperweight) also when the specific speaker, in this case the tweeter is disconnected from the unit.

But listen up noobs! Yeah! I’m a retardo when it comes to this crap- but empirical evidence doesn’t lie-

the freakin’ light turned green when I connected a shitty Sony speaker (thrifted it today for 2£ to test this brain fart) instead of the messed up tweeter.

the answer to my initial question of how to make sure that the speaker is the only issue is= use any crappy speaker that will put up a resistance of 6 ish ohms- and the green light will confirm your if this is the only issue.

I would like to dedicate this discovery to all of the gatekeeping autistic douchebags that feel the urge to point out how obvious this is.

nobody bothered to write this- and I KNOW that I’m not the only idiot who had this problem. So if you think that this answer is obvious: shame on you! – there is about 50 million (approximately) posts on the issues- and zero guidance on this rather lo-iq solution.

 

and by the way- the beolab 7-2 is insane. Even with the shitty Sony tweeter as a placeholder, well worth the frustration of coupling and fixing- and the thought of these things just getting dumped as the sidekick of the outdated TV it was originally paired with makes me queezy.

Gatekeepers suck- post the fix or choke on your own hairy nutsacks.

Anyways- hope this helps someone.
