What killed it, well after reviewing some PS4 gameplay I noticed that it was having audio issues, like it would allow some sounds but not all. It was almost as if it was receiving a 5.1 audio output but was missing the centre channel. Even though the PS4 was set to stereo.
After trying various cables, configs, and boxes. I narrowed it down to this box. Not sure what killed it, whether it’s just old, or that it’s been powered on for over 5 years straight. But its long service will never be forgotten in the hours of Netflix and Disney Plus it passed through to my recorder.
I see corrosion/deposits by those two leds and the hdmi… rinse it with vinegar, then DI water, then 90% alcohol. See if that doesn’t bring it back to life once it’s fully dry. You also might have to reflow the solder though.
I have another in the setup thats working, but I’ll probably hold onto it though if I can fix it as easily as you say
How would you reflow the solder?
With an iron? Or a heat gun? What would be the best approach for something like this with lots of tiny surface mounts?
Not who you asked but 100% use a narrow heat gun, no question; it saves so much time alongside not accidentally bringing connectors
Would an oven work?
If you have a hot air rework station, that’s one way. Because then it is temp and flow controlled and you can choose a suitable nozzle and direct heat to small spots.
Just curious since you clearly know a lot about this stuff: What are your thoughts on the heat sinks being a part of the issue? Is there a decent chance the device could benefit from replacing whatever adhesive/paste was used to attach them? Or is that even doable?
It depends on how much heat it’s actually making, but maybe if the factory job done was crappy. It’s probably thermal adhesive though which is harder to remove.
This.
I would absolutely try cleaning the board.
I would also spend $8-20 for a new one before I tried to DIY solder reflow various SMD caps.
