PS5 HDMI Issue (NOT the port itself)

[agehuntsville]

I've got a PS5 HDMI repair in front of me. After installing 2 ports (largely on the assumption the first one was defective or whatever), I tested the pads themselves after removing the second HDMI port. Pads 15&16 are shorted together. I know that's not normal. Where do those go to, so I can further diagnose? They run to nearby vias and disappear. The system itself seems to fully boot, as the light turns white, but obviously not displaying anything. Any help would be greatly appreciated.

Does it even stay on?

EDIT: It can be the Panasonic chip

these go string to hdmi encoder, so it's faulty.
take panasonic chip out and short should be gone, if that's gonna happen then u must replace. Ps5 won't turn on normally without working hdmi encoder

PIN15 &Pin16 goes to those test point and straight into HDMI encoder.

Weirdly, yes. It fully boots to white light and chills. Having one hell of a time getting that chip off the board, though. Even hitting it with 450C and a gallon of Amtec flux doesn't budge it.

Did you ever get to the bottom of this? I have one here with the exact same issue

The short on pins 15 and 16 in my case are caused by these 2 diodes that have shorted, thanks @jkyoho for the original picture.

I've removed them and the shorts have gone, but still no display, could it be that the Panasonic hdmi IC has gone bad due to the shorted pins?

Anyone know what the values are for these diodes? I would have thought they are protection diodes and the console would output an image without them.

I checked my EDM-010 donor board they are same marking code on those pin15,pin16 diode with pin18 diode like picture shown below. So they would be part# CDZT2RA5.6B

Just an update for anyone else who has the same issue, replacing the 2 diodes and the Panasonic IC has fixed the console
