that diode could be done for, this component is a SOD323 - C1 / A6 Tvs Diode it's mostly for circuit protection you can find a replacement here: https://www.mobilesentrix.com/hdmi-control-components-c1-diodes-for-playstation-5-ps5-sod323-10-pack
the 1pf cap you can test with diode mode on a multimeter if you get oL across the cap it's disconnected and if you get a voltage drop of 0 it's short-circuited any other reading/ changing readings is normal
I'd recommend reflowing the legs of the HDMI connector using a micro pencil iron and a generous amount of flux.
based on your symptoms there is a broken or shorted connection in the hdmi area check over via microscope inspection and redo your work as needed.
