Hey everyone,

This is my first post here.

I'm working on a PS5 Digital (EDM-020) and need some advice.

Short backstory:
It had no HDMI output, after that the port was replaced by somone else.
It had a signal for a short time when i was testing it, then it was only sporadic and now nothing.

After looking at the board it seems all pins of the hdmi are connected.
Components near the hdmi port are missing. (100nf cap near hdmi pins, 71 zener diode, backside). Others look burned.

I moved to the HDMI IC and noticed that a Diode? looked different from the others.
After measuring it with a Multimeter on the board, the Multimeter was beeping periodically and showed a resistance of 20.0 Ohms in forward and reverse direction.


Is the component near the HDMI IC a Diode? And what are the specs so I can replace it?

Thanks for reading!

That is normal and it is a 22 ohm resistor.
the 27k ohm resistor next to the big diode seem not siting properly.
ANY diode reading on the hdmi port?

Okay, thank you.
Yes, there are Diode readings on the port.
