Hi
I hope there is someone who can help me.
I have a ZP120 that flashes orange and white.
It will not play music, but if I hold the mute button for a few seconds, I can make it light dimmed white and I can play music.
But only for 2-3 minutes, then it pauses again and starts blinking orange and white again.
I have had it apart and there was a little corrosion on the print card, I have cleaned the corrosion and I could not see that something was wrong with the print.
Does anyone have an idea of what it can be?

Really great documentation here, well done!
Couple of observations.
-if you are getting the 3.3,8ish,15 on the secondary then the bias converter PWM is working correctly.
-The reason you are seeing 0V on the transformers pins is because you are looking at AC with your meter set to DC. Those biases measured in the logic card say to me that the bias converter is running and the output is making its way to the logic card. Good sign
-I can only think of one thing left to do, and that is measure the output of the buck converter on the bottom of the logic card. There is a inductor with a (normally) yellow electrolytic cap. Solder a wire to the striped side of the cap and put the card back in and plug in. You can put the red lead on the wire and the black one to chassis. Should have 1.5V output.

Do you know much about reading serial (UART) from a computer? You may have noticed a 4 pin header under the EMI shield that you removed. There may be some diagnostic clues coming out of that serial headder.

The one I am working currently has a confirmed good power and riser boards and shows up in the Sonos app but when you push play I get orange and white blinking leds. Wanting to read that header and see if it can give me a clue as to why mine shizes the bed when I push play.

i have 4 amps, that goes flashing orange and white when play is pressed. have you got any luck on that issue???

Blinking orange and white is fault mode. The Amp is either too hot, or there is a short. Make sure there is adequate ventilation and check that the wiring is not frayed or sticking out, causing a short.

Toden,
The flashing orange on mine was due to a bad driver IC on the logic card. It is a 14 or so pin IC.
Mine would flash orange and white when i push play, the app keeps playing like nothing is wrong yet no sound from the amp.

@brumster, yes those are thermistors part# SCK-054. Also hard to find here in the US.. I’ve found those on AliExpress as well. Any chance you have a part number or a alt part for the large 1000uF storage caps on the front end? Thanks!

I have for sale, 3 Connect:Amp power boards with chassis and bottoms (wifi antennas and white plastic pan) that are tested with a known good logic board. I can send you videos of them working with a pair of JBL towers.
You just drop in your logic card and your in business.
Message me at gruv2ths@gmsil.com if your interested.

you wrote about a bad driver ic on the logic board, you succesfully have replaced.
just to be sure, witch card is the logic board. the one with ethernet or the one rising from the powerboard
