So I have a PS4 sitting on my bench this time. The jack was definitely damaged almost beyond recognition so I swapped it out with a new one. The joints didnt come out terribly great but after following some of Andrew Paul's videos I was able to test each and every pin and had continuity without issue.
Problem is that I still get a black image and no sound when the device is powered on. Im using a monitor that auto cycles through inputs if it reads no signal but it will stay on the HDMI input so I know its getting at least that far.
I've checked for missing components near the port and the encoder ic chip and everything looks good. What values I could find I tested and didnt have an issue. Proper continuity across all four of the coils near the encoder IC chip. I also havnt been able to find any shorts, but I could be simply overlooking a few key components due to lack of a schematic.
So at this point Im starting to finger the blame on the encoder IC chip itself. Ive read that this can be a common failure along with damaged HDMI ports(though I dont know how a damaged HDMI port can cause issues to the chip like that. Maybe its a heat issue during replacement of the port?) I do not have a known good chip to test and I would highly prefer not ordering a new chip unless totally necessary. The rules of the company I work for makes it so if we have to pay to order a new chip in then its gunna go on the customers ticket regardless if it fixed the issue or not hence I really dont want to have to charge my customer for a new encoder chip if it turns out not to be the case, though this may be what I have to do anyways.
So what I really want to know is how can I test the chip to see if its at fault? And is there anything else I ought to rule out before the chip itself?
