I have this sub that broke years ago which gave me an excuse to get a new one. I didn't get rid of it because I was hoping I could repair it. I used to get noise from the sub when nothing was playing. Then one day it just wouldn't turn on. Today, I took the amp board out and took some photos. It doesn't look good, but I was wondering if I could replace some items that look scorched.
You can see the names for the components in this photo. The scorch marks make me feel like these components are toast.
This photo makes me think the board is actually cracked. I'm wondering if it would even work if I did replace the resistors and transistor on the board. And finally, here are the main filter caps (3300uf, 80V) and diode bridge rectifier:
You can also see the fuse in that photo, but it looks fine and not burnt out. Am I crazy to try and fix this board? Thanks for the help!
