Beolab 5 weird behaviour

Hello all

My right Beolab five has started to demonstrate a strange behaviour.

Today was the third time so I thought I would ask your opinion.

On a few occasions I have come home or got up in the morning. Once the right Lab5 was just off with no lights on it. I unplugged it and it was fine after the PIN number.

Second and third time when home from work the led was just red.

Turning the source on does nothing, pulling the Pl cable and putting it back in does nothing.

Switching the mains off and on after a few minuets and it’s fine after it has the pin entered.

Anyone experienced this?

Any idea what the cause might be?

Does anyone know a good place to diagnose and fix it?

Cheers

Hello All

Today the speaker was just RED LED again, went home for lunch, speaker didnt turn on with the others.

Does anyone know of a great repair shop or is it time for a new chassis?

Long shot - but take a look at my post https://archivedforum2.beoworld.org/forums/t/50149.aspx 

I replaced some capacitors in one of my speakers. Capacitors are generally the most likely electronic part to fail in any electronics...

If you're competent, you could take a quick look, as I did, but my BL5 did not exhibit the same issue. It's possible that if the capacitors fail in one of the power supplies, the unit could shut down.

Other than that, it's probably a new chassis, and as I have experienced, I would expect the other to fail in relatively short order. If the serial numbers are close together, then they will have been made at the same time and have had the same lifetime of usage.

Today I have ordered a new chassis for my Lab5 a few weeks of waiting but hopefully the problem will be resolved.

Hey mate, where did you order the new chassis from? I'm in the same boat from sounds (pun intended) of it and need to source a new chassis.

Hi there

I contacted a local dealer and asked for the service engineers number.

They quoted me a price to come to my home and install.

Cheers Sean - I tried my local dealer, but will try ringing around a few more places. Please let us know how you go. 

Just a quick update on mine. I managed to source a DSP board (PCB 5) and a ICE 1000A amp for the upper woofer (it previously had an intermittent crackle). After replacing both parts and transferring the speaker calibration settings IC (IC304 on PCB 5), all is well in the world again!

My replacement chassis is due second week of Feb, I have no idea what boards this is or if it’s all of them.

Currently the Lab5 is switched off waiting
