Hi everyone I'm triyng to repair an harman kardon ts2bq/ts11/I don't know how many name this subwoofer has...
The first problem was literally a hole big such a finger in the amplifer board with shorted mosfet and blowed up capacitors. After having fixed the amplifer board I've tied to turn it on, the results are two shorted mosfet and another problem.
After several tests with the tester I'm stuck, if I put the tips in the positive and negative of the diode bridge for a few seconds the tester tells me that there is a short circuit, after the value continues to rise up to 1560, after a few minutes it goes back to how it was before. I did these tests by removing the diode bridge (to check that it wasn't that) and removing both the amplifier board and the jack board.
What component can have this behavior? Could someone help me?
This is the datasheet
Thanks
