Hi All,

I have some 2008 Beolab 5. One of them started off being distorted. Now it crackles on and off and when it's working it sounds horrible! 

I spoke with a repair dealer, who says I need a refurbished chassis.

Now I'm wondering if I could do a DIY repair. I am familiar with electronics repair, having done quite a bit of it in the past, but I'm concerned if it's feasible or practical to do.

My initial suspicion is that it's as simple as a dry joint, probably due to lead-free solder cracking up. The speaker is fine when stone cold, but gets worse as it warms up, and the symptoms have been getting worse over time.

Any thoughts?

Thanks,

Andrew

From experience I can tell  you that your suspicion is not correct. If you start looking for these, you will waste your time. Causes are located inside the semiconductors on the UPC/sound board and/or ICE power related.

Quite a challenge to achieve "Less is More" while having the Beovirus.

Ah ok! Thank you so much!

Think I'll get a refurbished chassis fitted properly then. I can't afford to do it at the moment, sadly, so they'll be out of action until I've finished a few other projects.

The other one will probably fail at some point too :-(

I still love them - the best speakers I've ever heard.
