Why does only 1 of the USB-C ports work?

I pulled the logic board out and inspected it as closely as I possibly could, there are no signs of any water damage or any other type of damage that I can see anywhere on the board. I also took double care when putting it all back together and also cleared the NVRAM and the SMC. Still not charging with the USB-C port closest to the hinge. Is this machine just SOL? Anything else we can try or check? It wouldn't be a bad battery right? Cuz then I would think both ports would have issues.

@barylak - At this point the given ports logic within the logic board would need checking. it’s possible someone with deep logic board repair skills might be able to repair the logic board, you could just live with only one port working, otherwise one could replace the logic board.

This is not a battery issue or anything else

That’s what I was afraid of. It just sucks that the battery drains so fast because of the issue. Makes it a lot less usable as a mobile computer. Thanks

@barylak - What? You didn’t tell us that! So you have a short which is allowing the power to drain. If you have a thermal camera or even use a non-contact thermometer you should be able to narrow down where the short is. it’s likely a bad capacitor.

I mentioned in the original post that the battery drains super fast. I'm assuming this is all connected, the message saying the accessory is using too much power, the one USB-C port not working and not allowing to charge from it, while the other works, and the battery draining even when in sleep mode (lid closed). Definitely seems like something that would be difficult, I don't have a thermal camera, only a non-contact thermometer. So, i would be hunting and hoping that the thermometer picks up the temp difference while the machine is on and the bottom is pulled off?

There is only one controller chip in this series as noted in my answer. Reference MacBook Pro 13" Two Thunderbolt Ports 2019 Teardown check Step 5

The light blue marked IC is indeed the Thunderbolt controller IC and not the USB-C port controller. The issue described by the OP clearly deals with the USB-C and this model actually uses 2 controllers (one for each port) no matter how much one dislikes the answer.

@oldturkey03 - Correct your text as there is no USB-C controllers here. There is only two power delivery chips.

You assume I said something I had not. And again you throw distractions! Follow a logical process, don't jump to the last logical issue (which I did state clearly was the only issue left). Knowing when to stop is also important.

Don't assume people have the skills to do micro-soldering or even have access to the needed tools or even the chip. Someone who is not experienced can easily make a mess of their system. Just because we have the knowledge and skills doesn't mean they do.

So having people dig deep into there system to diagnose the failure is helpful! One also has to also aim people to the better skilled folks that can fix their system. In the same vane you wouldn't hand a loaded gun to a kid would you?

Couch your answers so people don't over reach! Simply say this will require more advanced skills and tool to fix that it might be wise to find someone with them.

Sorry, didn’t see these responses until today, I really appreciate the help being provided. I will try to post the best pictures I can take shortly.

I added a bunch of pictures to the post of the thunderbolt area, and the usb ICs
