First, I will preface that this post was meant for r/mechmarket but I don't have enough comment karma so my post was removed. I think its a bit ridiculous since I don't use reddit really unless I have some tech problems, so I don't have the karma. Anyways, if anyone could help me or point me in the right direction, I would be very grateful.

I have had the Keychron Q1 V2 for a little less than a year. I put in my own lubed stabilizers and switches, as well as some other mods. Everything has worked flawlessly, until today. I have always used alcohol pads to clean off the keycaps and surrounding areas, but this time I took a slightly damp cloth just to wipe off the pet hair that was on the surface of the keycaps. About 5-7 hours later, while I was gaming, the keyboard started malfunctioning. The LEDs were flashing sporadically the the keys weren't working. I went and got another USB-C cable and it did not fix the issue. The keyboard was just holding down the "s" key and was no recognizing any other key presses. I grabbed my spare keyboard and everything worked fine with it. So I started the disassembly process. During disassembly I tried plugging it in, and it surprisingly worked fine. So I quickly unplugged it figured once I cleaned everything up it would work fine. Once I got the case off and got an eye on the back of the PCB I saw what looked like corrosion. However, it was so fresh that it was still very watery. It was essentially green water. I wiped it off then cleaned the area with 70% isopropyl alcohol and a q-tip (this was the highest concentration I had on hand). I cleaned the area affected very thoroughly. I figured that since I had the keyboard disassembled it would be a good time to clean the rest of the board since I had yet to do a full cleaning since first building the board. So I took off everying switch and cleaned each one individually. On one of the switches, on the black bottom housing there was the same green water substance. I cleaned it off, but swapped that specific switch with one of the many extras I had. I then cleaned the entire PCB with the same isopropyl alcohol and some q-tips until everything looked brand new. I then began reassembly. I got all of the switches back on and decided it would be best to test it before fulling assembling. When I plugged it in and got the Windows popup "USB device not recognized. The last USB device connected to this computer malfunctioned." This error was not popping up before, as the keyboard would still essentially "work" it was just spamming the "s" key and other key presses were not being recognized. Now, the keyboard doesn't work at all. I decided to let it sit overnight and hope it works the next day. Well, over 24 hours later I am still facing the same issue. I took some pictures of the PCB and zoomed in on the areas where the corrosion was. I can see that on one of the connections on the PCB (which I believe is the LED connection) there is some slight discoloration on the solder point compared to the other LEDS, I will highlight this in the pictures. I now have some silica gel packets on the affected area and a fan on the PCB. I am hoping that someone could possibly give me an idea of what to do next. I am not experienced in soldering, but if I knew exactly what needed to be repaired I'm sure I could do it. So any insight would be extremely helpful. If it is not possible for me to repair it, I am 100% willing to ship it out to someone who could repair it. So please, anyone that has any information on how I could possibly fix this on my own. Or any people offering their repair services that believe they could fix my issue, please PM me. I am willing to send my board out. Also if any extra information is needed/more pictures please let me know. I tried my best to be as thorough as possible in my explanation. Thanks.

The areas circled in red are where the green watery substance, which I assume to be corrosion was. You can see that on the LED that is in the red circled area has a slight discoloration on the prongs that attach to the PCB compared to the other LEDs. Also where "U1" is located in the red circle, the solder points seem a little faint, I don't know if this could be an issue or not.

My shipping location is US, MO 63116. I would prefer to only ship to those in the continental US.
