Infinity BU-80 Subwoofer Trouble

[Tod B]

My Infinity BU-80 sub started to make a very loud & fast thumping sound
It would not stop until i unplugged the unit. When i opened it up,
discovered one transistor that had fallen off the circuit board. Th
spot where the transistor was previously attached appeared to have bee
sort of fried.

It is worth trying to fix this

The device is probably damaged and over heated. Normally, they replace the
complete board to service your unit. Contact the dealer for details.

yes, if you know how to. Refit a working tr and find out why it got
fried and fix it.
