This is from a Marantz SR5012. The HDMI output dies (tv goes to No Signal) after about one minute. It works fine until then.
I'm losing my 5v at the HDMI output connector when this happens. The voltage drops slowly (over maybe 10 seconds or so?) From 5.2v and the port drops out around 2v but the voltage continues to zero.
The 5v coming in from the left is direct from the SMPS. The output from the MOSFET goes to the HDMI port.
Will take measurements in the morning but was wondering in layman's terms how this circuit works ? Thanks
