Last October (I think) I bought a Logitech Z5500, a few months ago they decided to die. To be more specific, the subwoofer died.
Logitech sent me replacement control pods, which didn't solve the issue (before I figured it must be a problem with the sub).
Anywhoo, they sent me a Z906 as a replacement, since the 5500 is out of production. I'm happy that I've returned to hearing sound again, highly dissapointed that the 906 does't match up to the 5500s performance (even though it died).
I still have my 5500 speaker set and was wondering, if there's any support I can get to repair the 5500s myself.
I studied electronics at college, so I'm not a complete noob, I just don't want to dive in and potentially cause more harm.
Is there any further assistance Logitech can give me?
Are there any 3rd party companies that can offer repair services for the Z5500's?
Has anyone else attempted to repair their own 5500?
I have googled and youtubed my eyeballs off, and haven't managed to find any useful tips/ tutorials / guides/ how tos etc.
My initial problem was that my control pod would randomly turn off. Then eventually turnt off completely and never came back on even to standby. Fuse is fine, everything else in my home is working fine.
I do remember smelling something burning in my room one day, but i never figured that it may have been my subwoofer.
So either the power supply, or the amplifier has blown I'm guessing.
Anyone have any ideas of where to go next with this?

Sadly, Logitech (to be fair, almost no one does anymore) repair anything.
Only thing they do is replace.
If you are not happy with Z-906, you could try to sell it, and use that money to buy another set of speakers that is more to your taste.
One *might* be able to find place that repair things, but they are getting harder and harder to find.
Look for generic "Electronics Repair" guys. Don't bother with big names like Best Buy, got to find yourself a real electronics guy (or gal, although I have feeling they are even more rare).
I was in the same boat as you, and Logitech was good enough to send me Z-906. I actually prefer it over Z-5500 (I had 2, now my wife uses the Z-5500, and I am on Z-906). So I lucked out.
I do my own repairs a lot, but Z-5500 was beyound my skill.
I refrehsed all the joints I can get at, and looked for any component that was damaged.
My guess on what's wrong is one of those capacitors, but I couldn't find any that are visibly bulging, or burned.
The op-amps rarely goes bad, but I have no equipement to test them myself.
I did look around to find me a repair guy, but I couldn't.
In the end I gave up.

It's interesting that you mention the capacitor.
Before my speakers actually died, I could play music for around 30 mins more or less, then suddenly the power would cut out.
The control pod would stay in stan-by mode, and some of the pixels in the LCD would remain on. Which suggests that there was still some charge trickling from the capacitors, till eventually (I'm theorising) they have finally blown and hold no charge.
I will continue to investigate my current system, and look for an electritian. I actually have one in mind.
If anyone is following this topic, I'll try to keep updated with progress, if it may help anyone.
