I am surprised to hear of a problem with BL1s. Guessing you have swopped leads and proved your power point is working ?

Hopefully someone else on the forum has been inside one of these.

I have checked the power and changed the cables....one thing I did not see before is that the standby light is actually on but very very dim so it is very difficult to see.It is not bright like the other speaker and does not go to green when the music flows.The speaker remains dead. I also changed the powerlink cable from the woofer but still dead.

What happens if you connect the Beolab directly to the Beocenter? Just to rule out a fault with your Beolab 2.

Thanks. I'll try that. In the meantime I had a response from Detron in the Netherlands who handle vintage repairs and fixed my Beosound 9000 at a huge cost but have said that they cannot fix a Beolab  1 speaker cus no spares. That is unacceptable . I'll talk to B&o directly on that because the initial cost of these speakers means they should never fail/ or be repairable in a seamless manner. Quad speakers have a seamless/cheap repair process and that is how service should be. I have everything B&o from phones to surround to TVs and my view is that if you make an expensive commitment to a design brand that is a lifetime reciprocal commitment. Let's see.

B&O doesn´t work like that, unfortunately. Some spare parts you can get, some parts you can´t. The CD-mechanism for the BS9000 Mk1 for example, you can´t get anymore.

Your Lab 1 has a power issue and perhaps it time to open it up for a look. The problem may not be a failed component,  It could be something obvious.

Hi John.

Is simply. The red light works? 

If not, is the electrical componnent inside. It is not normal in this type of speakers. We never have this problems.

Also, if you need to send to any service, get out he plate base support. This is half or weight from the speaker. Send to Italy or Spain B&O Service.

I will send one email with the details contact.

I have downloaded a brochure on how to dismantle the BL1. However, when you get the front panels off it is clear that the problem is in the electronics and around the LED which only becomes clear when the base is off. So the unit is raised and on its back with the base and the panels off. The area around the LED seemed dirty so I cleaned it gently, connected the power and the solid red standby light came on! So iI connected a power link cable and connected to a B&O source turned it on and the light went green....but only for a millisecond and there was an audible clicking around the area of the LED when it went on and when it went off. So it seems a loose connection of some sort but can a unit like a BL1 fail with a loose connection....or could it be a deeper issue. Any suggestions.

Could be a blown tweeter, swap them around and you will know
