My daughter's HK695 is blowing fuses. Not real fast but after a few hours of playing, even at low volume the fuse will blow.
I want to open up the woofer (which contains all the circuitry and controls) and take a look.
I removed all the screws in the base but I can't seperate the base from the shell.
Thanks In Advance,
Pete C - I had the same issue, and the same frustration.
The key is-> the floor bumper on the back side has a hiden screw under it. Remove the bumper, then stick a hook in the hole to pull out the plastic plug, then the screw is accessable. Good luck on finding anything inside.
I got one HK695 and faced exactley the same problem opening the woofer.
First remove all the screws down under the base then remove the safetynet and then the element. From there it posible to seperate the base from the shell after the screws are remowed.

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.
Maybe. There should be a fuse. It will prolly look like a black knob on the back of the sub. Unscrew it and check the fuse. Replace it with a good fuse. If it keeps blowing the fuse, the problem is likely in the speaker. If the problem is inside the sub, you may need to repair/ replace the circuit board inside the unit. If you can't get one you will have to replace the speaker as it will keep blowing fuses.
the noise is sometimes caused by dust in the volume control.
i would suggest blowing the dust out around the volume control if there is a manual control on the unit. use a small can of compressed air.. buy it at local walmart or computer store.
Did you have to replace the fuse? Was it opened? Sometimes there is a THERMOfuse INSIDE the transformer [xfmr].Before it blows because of too much heat ,it may blow the 2a 250v external fuse.You must check the power supply [the circut attached to the fuse] input should be 120 a/c in and around [+] or [-] 12 v thru 15 v DC output. Look for filter capacitors & resistors that look like tiny cement blocks(they are thermo type fuse resistors) BE KILEFULL !!! (CAREFUL) the voltages are low but the current could be high. Could stop your heart!!
