Customer Question
Merry Christmas! I bought...

Merry Christmas! I bought a house with a Russound CA6.4i. It hasn't worked. All zones (except 1) will turn on/off but no sound. One zone stays green regardless if there's anything plugged in for keypad/speakers or not.

Technician's Assistant: What is your speaker connected to or paired with? Are all cables connected tightly?

Russound CA6.4i. All connections are confirmed tight

Technician's Assistant: Have you tried a different audio source (e.g. another TV, computer, or CD)?

Yes, tried multiple input sources

Researched showed because of the age of the unit some capacitors could have caused to leak in the power supply / protection circuit. In particular it has a problem with protection IC 10 (uPC12370). Check the Cap C28 (2.2uF/50V). If you read any AC
Volatge on that Cap, it means Cap is dry. Replace it with 4.7uF/50V.
In other words the unit unfortunately needs repair. Average repair on the unit for this kind of issue should run between $85-$120. Let me know if you have any other questions. I'm more than happy to answer them for you. Sorry I don't have an easier fix for you.

I've read that post from another thread & have replaced the C28 capacitor. I still have a green light on one of the zones.

That is the only issue I have seen on this unit. Otherwise it could be a control circuit issue, which I have not come across. I will opt out in the hope that another expert has an idea for you. Good luck.
