Hello
I have a Sonos Play 5 version 1 here. I have already changed the PWM only the diode or transistor with the code F2 is defective. Does anyone have any idea what it is? I also do not find a correct example circuit on the internet to possibly find out for myself.
Ciao

Hello,
What makes you believe is defective? This must be a similar problem with mine, it’s related with the Vcc on pin 7 of the IC. What is the voltage you get on this point (arrow)?
It comes from the 100uF 25V small cap between the big fat ones at 400V.
That cap is the kay to my problem, it does not charge up to supply the power to the PWM chip.
Any details you figured out?
Thanks
