Question about Audio Players & Recorders
I have the cambridge extreme 2.1 speaker system, which consist of MC105 x 2, BassCube 821. I have sent it back three times in a little over a year and now they wont fix it for less than $200. I now have the same problem that I've had all three times. The sub blows the fuse and when you put a new one in, it blows as soon as you turn the power on.
Fuses blow when there is an overload. This is most likely caused by the main power amp part of the sub. Or it's power supply. What's happening is that some part is acting like a piece of wire instead of doing it's job.
It's possible that the previous repair people fitted the wrong part and if you are using it at say high levels it goes again. It could also be caused by faulty speaker wiring. So check that after replacing the faulty part. It might be visibly burnt or broken if you look inside it.

SOURCE: no sound
I had the same exact problem, here is what someone else suggested I do:
I had a problem with no audio and I recently found the fix. When thesub still worked and you turn it on you hear one relay click and thenabout 5 seconds later a second relay clicks and the audio comes on. Theproblem I had lies with that second relay. When you take the case apartthere are 4 circuit boards. The big board with the two big bluecapacitors is the main board. Well next to the two blue capacitors is ablue relay. That relay had a pin that came un-soldered from the circuitboard. I re-soldered that pin and the sub works just like new.

Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).

SOURCE: Fuses keep blowing
This particular product has a lot of comments posted on it and I've answered a few of them now so I'm beginning to think you may want to look into weather or not the manufacturer has received any complaints or this is just a freak occurrence. Keep in mind not all commments are the same so this may just be nothing. Either way I can tell you this much, if fuses keep blowing quickly, over and over again-You have a direct short somewhere and will most likely be in need of professional assistance of some sort with the possiblilty of having to replace it. I'm sorry it's not an easier fix but it may not be too expensive.

More than likely the power supply switching transistors have fried. Also check the large caps in the primary side of the power supply. If you don't know what your are doing do not attempt to fix the power supply.. very dangerous voltages involved !!! Send it to Klipsch for repair or purchase a Bash replacement panel http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-750

Hey! So i fixed my problem! This is for the BassCube 10
Like i said before i saw that the circut board was burnt near the diodes ZD3 & ZD4, and the resistor R63. Thanks to Deadly1 and BillRad62, i figured it out. The R63 is a 1200 resistor, and the diodes are 15v zeners. I went with 3x 5.1v zeners to replace ZD3, unfortunately Rip-Off-Shack (Radioshack) didnt have 3 packs of these so for the ZD4 i put a 12v and 5.1v. Which exceeds 15, but seems to work without a problem. Hope it helps!
