BeoLab 8000 no Standby light and no function

Reply Contact

Hi got a Beolab 8000 as has no Standby and complete death
The Fuse F1 and F2 is ok
also the thermal fuse is ok
Fuse resistor R64 on PCB02 is ok

So I guess the error is in stand-by transformer ?????

I'm not sure and since I have to order a transformer
I would like to sense if anyone else here had the same error on his Beolab 8000
and can perhaps help me find the error on my BL8000

regards

Jan

I have had this fault and it was indeed the standby transformer. I bought a complete new transformer board.

Thanks Graham for your response, I was not sure with the stand-by transformer and thank you very much for your reply stating that my guess is quite right I'll order a new stand-by transformer after I changed it I tell you if I have Beolab 8000 started again.

The standby transformer outputs to the power supply board via an interconnecting cable. If you have no standby input to the power supply board then the standby transformer must be burnt out.

There was a reason for ordering a complete transformer board but I don't recall what it was. Maybe the transformer alone was not available??

Hi,

I too got that on a supposedly "dead" 8000.

Not so: the white connector in the PSU block had somehow found its way inside the block!

I just pushed it back in place!

PSU: power supply, transformer et al.

I have succeeded, my Beolab 8000 works again. The error was on stand-by transformer.

Have attached a photo from trafon I have opened that you can see that it is burned.

For trafon I paid 45 pounds including shipping.
Next time when similar errors, we know where to find the error.

Regards Jan
