Hi everyone,
my first post!!
I'm a service engineer in an audio rental company.
I have a Sennheiser in-ear monitor ew300 g3 iem completely dead, no display, no led, nothing.
In-ear monitor is simply an advanced wireless headphone composed of a transmitter and a receiver called bodypack that drives the headphones you can see in the ears of all the singers and other musicians.
Probably it's a problem with a DC/DC converter, but I can't find the circuit diagram or the service manual on the web and I can't locate it on the PCB.
Could you help me?
Thanks in advance
Simone
