I captured waveform and paste HDMI circuit as talked on the phone yesterday
The waveform I captured has only TMDS differential signal connection with HDMI TV.
Others signal is dis- connected by remove serial resister jumper.
First waveform as below is captured when system board is without power and HDMI output port connect TV.
And you can see leakage power on 3.3v net.
Second waveform as below is captured when system board is without power and HDMI output un-plug HDMI TV cable instantly. You can see the leakage on 3.3v is drop immediately
(Yellow is 3.3V power supply; Cyan is TMDS signal)
