The Control center on my 5500 keeps dropping after a few minutes..Sometimes it powers up and immediately goes off..Or with some jiggling will stay on a minute or 2. Then I hear crackling or static from the speakers and it switches off at the control center, I called Logitech and they will not sell me a new controller. They will only sell me a complete new system... It's only a little over twoyears old..WHat a waste. The speakers are perfect, the S/W appears to be fine. I dont know if the short is there or in the controller. I suspect the latter. Logitech dont want to know. Is there anywhere I can send it for diagnosis? Wonder whats causing this....
same one but i can not see the value od the diode if someone can please help me outsame one but i can not see the value od the diode if someone can please help me out

It 's not the fuse!!!! THAT fuse is only for SUB !!! if that fuse was the problem he wont have power at all.THE problem is with control center .I fix my control center changing 2 diodes ,but a friend of mine have exactly the same problem comming from some transistors with is located above that 2 diodes D700,D701(so he says) --- surf check google and you ll see a lot of customers with exactly same porblem AND THIS PROBLEM I THINK IS SOME DESIGN ERRORS THAT AREN'T FIX BY LOGITECH BEFORE SELLING THIS SYSTEM!!!!!!!!!
Take out the fuse and check it out... if you see the metal disconected then its the fuse.. the fuse should be in the back of the sub some where if im not mistaking.. you will need a butter knife to take it out... look close for it.. its not a acual screw its like a black peace of plastic with a grove in it to put a flat head screen driver..

Try pulling the power from the unit for a few minutes, the reconnect. Make sure you've got the surround settings correct. If that doesn't do it, you've likely popped the amp or the amp's power supply in the sub box.
if there is no light on the control, check the mains fuse on the back of the woofer box, if blown, you may have an amplifier ic (tda7294) blown (there are 6 on the big board), replace the ic, if still no sound, mute may be blocked in on position, on small side board there is a transistor (2n4401) connected to a white wire going to the big board, replace the transistor (you may use a bc337)
Logitech does not sell these seperately.. not in my country anyhow. You should also be aware, that there is several (at least two) revisions of these controllers, so you cant just just use any controller.. Check eBay.. and try to get one that has the same sticker on the back of the stand as yours. EG, mine is R750. Good luck!
Well you have some options, you can either live with 2 speakers and change the settings back to default. Im assuming the colors you have are orange black and green. black= the surround sound speakers. orange= center and subwoofer. green=right left front
Now if u want true surround sound then you need to buy a new card that had all the ports for your speakers.
To troubleshoot a speaker system where sound is not issuing from all speakers, please do the following:
Verify that all cables are plugged in correctly. Make sure the rear
and/or center/sub audio cable is plugged in to the correct port. On
most surround sound cards, the rear audio port is black, the front
audio port is green, and the center/sub audio port is orange. If you do
not have a surround sound card, make sure you obtain the proper adapter
(discussed in the next paragraph) or use surround sound emulation if
your speaker system offers it. If you are not sure if you have a
surround sound card, please check with the manufacturer of your sound
card for details.
Make sure your sound card supports the same amount of channels as
your speaker system contains. For 4.1 systems, it should have a front
and rear speaker jack on the card. For 5.1 systems, the card should
have a front, rear, and center/sub, output. The card should be properly
installed and configured. Please contact your sound card manufacturer
for details. If you do not have a surround sound capable sound card,
you can use the source selector switch or the M3D button on the controller unit (if available). You can also use an
adapter to split the signal for the front and rear speakers. This type
of adapter is a 3.5mm male to 2-3.5mm female jacks. You can purchase
this adapter at your local electronic store. Please refer to your
manual if you do not know if your speaker system can emulate surround
sound.
Try connecting the speakers to a portable sound device such as a
walkman or portable CD player. Plug the speakers into the headphone
jack, but make sure the volume is lowered so the speakers are not over
powered. You can do this for both the front, rear, center/sub speakers
to verify that they work. If the speaker system works on the walkman,
then you are experiencing a configuration issue with your sound card.
Please contact your sound card manufacturer.
Check the system Volume Control located in the System tray. Make
sure that the volumes are at a reasonable level and are not checked for
Muting.
Hope that helps! Should you have any further questions,
please feel free to post them here.

Hi Nick
As you talk I remember a spair speakers I have a long time ago, brand Creative 5600, has a bad resistor inside the speaker SB, or board, you also check for bad cable at the back or static.
another thing is your volume control, sometimes if you down a few notch you may ...not feel the hit or beep, but check things first.
good luck
same one but i can not see the value od the diode if someone can please help me out
