I have a ps5 sitting on my bench that is giving no display. I’ve replaced the HDMI port 3 times, along with the Panasonic chip once. I do know the #1 trace on the HDMI port is damaged, but it is still connected (damaged as it’s lifting up).
The PS5 is giving no uart codes before/after Panasonic chip replacement, and post/boots normally. I have tried several hdmi cables and monitors, still nothing. The PS5 has been worked on before me, and they left the HDMI port very messy, but I can’t find anything missing or out of place.
EDM-033 Board with a disk. I have also verified the pins on the hdmi are all correctly connected.
TL;DR PS5 EDM-033 board, no display, no uart codes. Replaced HDMI x3, replaced Panasonic x1.
Diode Mode: Red probe on ground, black on the pins you want to measure.
Resistance Mode: Black probe on ground, red on the pins you want to measure.
Voltage standby: Black probe on ground, red on the pins you want to measure.
Voltage power on: Black probe on ground, red on the pins you want to measure.
Scratched the beginning of the trace near the via on 1 and 12. Got 250k on 1, but still nothing on 12. Ended up just soldering a wire from the via to the pin making pin 1 work again (as stated, it was a broken trace).
So now it’s just 12 that currently missing any continuity.
If the soldering on pin 12 is ok, I would check for continuity at the EMI filter. If you look at the HDMI chip there are eight lines which go straight up to the HDMI port. The most right line is the line for pin 12 at the HDMI.
I would check if the matching pad at the HDMI chip has correct readings and if the line continues through the EMI filter (most right little white square towards HDMI port)
The filter had no connectivity, ended up just being a bad connection on the Panasonic that needed to be resoldered.
Everything currently shows corretly, except for pin 18, on diode mode, it is giving me a reading of .078, although I belive that is becusse of the missing component that usually connectes 18 and 17 together (never had issues in the past with that missing).
After testing, I’m still not getting any HDMI signal out of it, and still no codes. PS5 does boot corretly.
if you are talking about the 100nf cap seat between pin18 and 17, that cap won’t make your pin18 low resistance to ground(.072 diode is closed to “short to"ground”). You might need to check other side if anything goes wrong.
I have managed to get the HDMI fixed, turned out somehow pin #18 was shorted to ground via pin #17 (pin itself). Ended up purposely removing pin #18 pad and just soldering a wire in it’s place. PS5 is fixed now but super weird issue.
