A few years ago, Rachel bought me a fantastic Christmas present; a Logitech Z5500 5.1 surround sound system from Insight UK. It was great for gaming, films, and music. Earlier this year it suddenly died on me – everything seemed to be functioning correctly on the display, except there was no sound.
Fast-forward several months, and I opened up the control pod to take a look inside, and the cause of the malfunction was immediately obvious; the Cirrus Logic CS42526-CQZ had blown – DOH!
A quick search on Google shows I’m not the only person with the Z5500 suddenly dying (for various reasons), and here’s someone with exactly the same problem as me.
I wonder if Logitech is aware of this problem? Additionally, perhaps it might be possible to get it repaired under the Sale of Goods Act: “the key time span is six years. That’s how long goods may be covered by the Sale of Goods Act.”
I’ll contact both Logitech and Insight to see what they say, and report back here.
Finally, the IC itself costs less than £10, so of the above fails, perhaps I can find a friend with the tools and skill necessary to replace surface-mount components.
[Update: It's fixed!]

Iestyn, my dad uses a company to repair PCBs. You can send them a mobo and they part test every component and replace anything that’s damaged, I think it costs him about £40. He’s had his washing machine mobo repaired a couple of times now – still more economical/encironmentally friendly than buying a new one at the moment. Drop me a line if you want the details.
Hey Will, that company never replied to my email
Got it fixed now though
Hi,
Can you supply me with the replacement part numbers please?
Seems another dead z5500 Down Under…..Logicrap are no help what so ever!
Cheers J
Hi LB,
My post here links to the replacement part on Farnell. Hope you fix it!
I changer my blown chip yesterday and everysting work fine except the analog imputs.It seems that if i connect the audio jack to imput 3 i have signal not only on channel 3 but also on channel 2. (direct imput 2 and 3) and the sound is weak and with problems.The guy that installed the cirrus logig IC told me that is strange that 2 pins of the IC are in short.
DOes someone have a scheme for the hole PCB of the z5500 pod?
