No power in Z-5500 logitech speakers
The logitech z 5500 digital is very sensitive to power peaks. One of the most know problems is that the fuse breaks because of these peaks. I´ll show you how to replace the system´s fuse.
First of all, you just need to write down the specification of the system´s fuse. The system´s fuse specifications are printed in the back side of your subwoofer, right next to the subwoofer´s on/off switch. In an european system it says: "T2AH250V (Time Delayed)". If you use another power voltage (120v), it may say something different. Anyway, write it down on a piece of paper and go to an electricity store and ask for a similar fuse (It is very cheap. Not more than 1$)
-The best way to get a similar fuse would be by bringing the broken fuse with yourself to the store-
In the back of your subwoofer, using an screw-driver, un-screw the fuse´s cover and remove the broken fuse. Replace it with the new fuse, attatch it to the cover and screw it back again.
If you turn on your system now, it will probably work fine.
