Hi all,
I have a dead B&W ASW610XP Subwoofer. Original plan was to just sell the driver and not attempt to repair it. However while stripping it I found some burnt SMD resistors on the power amp board. They are quite large so I think I can replace them, but reading the numbers is difficult (see image). I think they say R280, but what do you guys think?
I guess these resistors don't go bad like that for no reason. The second image is the other side of the board and I notice there are some MOSFETs close by. Might they be the root cause? From what I've read they do fail. I've read about testing them with a multimeter, do they need to be removed before testing? Or can they be tested in situ?
I'm not an electronics engineer, just a curious guy having a go. I am happy to replace a few components, but that is as far as my knowledge goes. No big deal if I cant get it working.
Any advice appreciated.
Many thanks
