Need help for my first keyboard build

[MarkL97]

First of all, i have no idea if it is the right place for topic. If it isn't, i apologize.

 
Hello guys, this is my first time building a keyboard (XD60). I soldered all the switches on the PCB and everything worked perfectly. Then, I found out that the left Ctrl, left Fn0, and left Alt switches were in wrong positions. Then, I de soldered them and soldered them into the correct positions. After that, everything went wrong.

All the red keys and green keys have no response when I press them.
When I press a blue key, it will show a green key on the same row. For example, when I press “8”, it will show “5”

This is the first time I have ever soldered anything. I made some mistakes. When I was de soldering the left Fn0 key, I lifted both pads. Other than that, I have no idea what I have down wrong.


Please help, I don’t want to give up on this keyboard.

Thank you.
