How do you take out the fuse on the back of the subwoofer?

I tried to remove the fuse as it may have blown; but am unable to loosen the fuse cover . I tried using a screwdriver on the top slot; but it didn't loosen the cover.

Why isn't my Logitech Z-5300 speaker system no longer turning on at all?


I have a suggestion that you can try. If the unit is no longer turning on and you're sure the electrical outlet is good (by plugging in another device) and the hand-held control panel is on, as well as the switch at the base of the subwoofer, then try replacing the fuse. The subwoofer on this model has a fuse near where the power cord enters the subwoofer. There is a slotted screwdriver slot on the fuse cover. Using a flat-head screwdriver (or your thumbnail), turn the cover about a 1/4 to a 1/2 a turn and the fuse should pop out. Keep the cover. Replace the fuse with a 4 amp, 125V (or higher) fuse that is a slow-blow fuse. There are fast blow (or fast acting) and slow blow (or slow acting) fuses. You can't replace one for the other. You should be able to find a fuse at Radio Shack. If a new fuse doesn't get your system working again, then something else is broken. Good luck.

I have a logitech Z-640 speaker system connected to a Panasonic Plasma TV and the sub woffer has no volume coming from the large speaker.All the other speakers are OK It seems there is no power going


Hi Ray,
if there is no power going thru than,might probably be your fuse in the subwoofer that's blown.What you have to do is remove the wire mesh from the front using a terminal flat screw driver. You will notice that there are screws around the speakers,remove them inorder to take the speakers out.Once you've done that take out the speakers gently so that you dont disconnect any wires inside.Turn the peakers over and you will see a fuse attached to the speaker.Try replacing the fuse with the asme ratings.
Please refer to the image below on what the back of the peaker looks like.
All the best and Good Luck.

I have a logitech x-530 5.1 system that doesn't work. when i pulled the sub woofer apart, all I found was a blown fuse. What caused the fuse to blow? Also,what would be the voltage of the secondary side?


Hi there bud , The Blown Fuse could of been cause by maybe a Power Surge or a Power Trip...If this hasnt happened then it could also be due to faulty wiring in the Subwoofer itself when it was being produced.
What you can do is , take it back to the shop and have them replace it...Dont inform them that you had opened it as then they will delete your warranty...
Hope this helped bud
Happy new year

Need to open my logitech z 2300


On the back of the subwoofer remove all outside screws running the parameter of the metal back. You should do this with the speaker pointing down so the screws face upward. Once you've removed all the outside screws lay the speaker back in it's normal position and grap hold of the heatsink fins and give a slight twist to it to break the seal. That will loosen it from the back, and you can pull it out about 3 inches. Note: wires are still attached but that should give you enough access to get inside.

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.

Loose jack on subwoofer -- fixable?


Hi, since you pinpointed the problem, the correct solution would be to replace it. However, if you want to try a temporary remedy, try using a glue gun to put glue around the jack's outer housing while connected to the back panel. Make sure that the glue dries in the correct position (where there is sound from the satellites). It is possible that the sound waves produced by the subwoofer loosens the connection. It might also be helpful if you lock the cable in place so that it will move so much and strain the jack. Regards.
