Hello all,
I just registered on this forum and hope that someone might be able to help me. I am trying to repair an older B&W Zeppelin for my parents. The status light is blinking red which according to B&W means that it need a repair. I searched a little bit around the internet and the power supply of this product seems to be a common problem.
I decided to open it up and take out the power supply. The first thing I noticed was that all the caps seems to be of good quality. Rubycon on the dc side and Panasonic on the ac side. (Excuse my terminology I am very much a beginner here).
However one of the caps a rubycon 2200 uF 16 VDC seems to slightly be bulging. Also there seems to be several burned spots on the backside of the pcb.
So as I see it there are two options:
- Replace some caps?
- Replace the power supply board for a new one (expensive)
Replacing the whole power supply will be quite expensive however might be worth it if this is where the fault lies. But how sure can I be that it is the psu? Also I have never replaced caps before at all so I am very much a beginner. Please keep that in mind.
I have attached some pictures of the board. Any help will be appreciated. The name and make of the psu is Abletec ALP0050-0000-H. Specs: +25V max 1A continuous 2.2A FTC/+5V max 1.5A continuous.
