Well, after 4+ years with my nice 4.1 system it has finally bit the dust. Should I bother trying to fix this or not? Below are some pictures of what has happened. Has anyone else see this before? Before I finally found the fired circuits I browsed the forums and everyone said to check R12, R26 and the bosh board but they were all fine, my fuse was blown so I replace it and tried firing it up again but all I heard was another loud pop. Both the circuits are blown I only took pictures of the one because that one shows a whole and one leed completely burnt away, the other is just cracked. The sub was not connected to a surge protector, so I am pritty sure I know what happened. But why these ciruits and not just the fuse?

hey i have a 220v set with the same board appears in many different BASH pc speakers, including the klipsch promedia 4.1 series. my (very old) Creative megaworks speakers seem to have the exact same Indigo 640023 rev1 power board in it. Can measure what component values are for R16, R17, C11 and D4. These seem to have fried on my board and need replacing however the data on the bill of materials for this board seems to be very hard to get my hands on!
