Infinity BU-80 Subwoofer Trouble
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, I discovered one transistor that had fallen off the circuit board. The spot where the transistor was previously attached appeared to have been sort of fried.
It is worth trying to fix this? |

Infinity BU-80 Subwoofer Trouble
The device is probably damaged and over heated. Normally, they replace the
complete board to service your unit. Contact the dealer for details. -- JANA _____ "Tod B" wrote in message ... My Infinity BU-80 sub started to make a very loud & fast thumping sound.
