Default sonos connect amp

hello
I bought a faulty SONOS connect amp, with a fried TC2001 (tripath), I don't care about the amplifier, so I removed the (remains of the) chip, managed to conect output lines (line level), and the unit works !! but it is in the "fault" mode, flashing white and orange, this conditions prevents to use the volume slider at full volume, it always backs down to about 60%.

anybody has experience in such units ? maybe a (parcial) schematic?

thanx !!

Al

Haven't tried it, but a new tc2001 costs about 3 usd on ebay...

Indeed, the solder paths are all burnt, due moisture and heat of the damaged chip, besides this chip is a driver for larger chips, i don't want to repair the power section

Thanx

Mmm as far as I could see, the amp section is fairly separate from the rest. I don't think the tripath does anything other than giving a 'fault' indication to the main processor.

But I am no expert...

Was reading this thread because I have exact same issue with the Sonos AMP.

It goes into Fault mode (orange-white blinking LED).If you turn it on, after booting, it runs for a minute and then goes into faulty mode.

I have feeling the TC-2001 is faulty because it's the only thing left in all honesty.
All voltages are there and there are no faulty components found.

Seems like the it goes into "sleep" mode for some reason, the voltage of power amp goes from 36V to 18V.

Problem is on the main board for sure. I exchanged the other print boards from a working AMP and problem stays.

Any advise or info is welcome!

How about seeing if a move to the Class D forum elicits more response.
