Did you try just the beolab 8000 without the masterlink?

Is the beomaster set as a master? Is it in option 1 or 2?

Yep, that capacitor certainly doesn't look happy, and the one next to it looks like it is bulging too (although it may just be the way the light is reflecting in the photo).

The electrolytic capacitors are the usual culprits when the BM5 is shutting down randomly or refusing to turn on. They can be replaced, but it's not as easy as it might seem - it's a multilayer PCB and at least one leg of each of those caps will be connected to the ground plane which acts like a huge heatsink, drawing away all the heat when you try to desolder the old caps.

It's an easier task if you can pre-heat the board, but this maybe a little outside the scope for a lot of DIY soldering setups - without pre-heating it can be a real struggle to clear the holes without damaging the pads or through plating.

Totally agree with you. I have had lots of troubles with my BS5/BM5 in the first times; now it works fine, but I need to replace the original HD 1 Tb capacity with a 2 Tb, if possible.

Let's keep in touch

Hello Martin, I think you did an excellent (and corageous) job.

I need to do the same, so I hope you will help me in case of trouble.

Regards

It seems like there are 2 more capacitors which are not ok, just on the other side of the cooling unit.

I am going to give a try and to replace them, I mean if it‘s the reason why the BS5 screen is going to be black and the music stops than I‘ve no choices - repair the installed mainboard or replace it with the Epia EX 1.5GHz because it looks like it works more reliable. But first I try to repair the capacitors.

If you haven't already tried the replacement you might consider trying to cut the existing capacitors out whilst leaving as much of their legs protruding from the pcb as possible, then solder the legs of the new caps to these. This will probably mean securing the new capacitors to the board on their side with some silicone - this will mean you don't have to worry about desoldering the existing caps and avoid any potential damage to the plated holes (be sure to use neutral cure silicone if you go down this route though, as normal silicone releases acetic acid which can damage the pcb and nearby components during curing).

Kind regards,

Martin.
