As above. Is this an upgraded model? Seems to have Wifi and optical inputs.

Okay, need help/advise on M50W.

No power to the subwoofer/control module. Replaced the fuse (2A) at the transformer end, still blow when I turn it on. There's a "boom" sound from the speakers.

What would be the next step? Try a higher fuse?

The treble part and the bass part each have their own fuse (on the PCB), the fuse on the transformer should be the primary side. Can you remove the fuses on the PCB / remove the connectors from transformer to PCB and see if it still blows?

Thanks for your response. If I get it right, I’d remove the 2 fuses on the PCB and connectors from Transformer to PCB. This is to test if the PCB is working? The fuses on PCB is glued. How do you suggest to remove it?

Removal of the fuses is just to see whether the transformer fuse still blows. Do not operate the board without fuse by shorting in place of a fuse.

It's glued but the glue is not necessary for electrical nor mechanical connection in the fuse holder, so just take it out.

Noted on that. I don’t get what you mean by “operate the board without fuse by shorting in place of a fuse”

I see. Oh my question was how do you physically remove the glue (hot gun?) that’s holding down the fuses.

Just pull it out. The glue is not hard.
