Yes PCBs are much more robust than people think, it's common to use lemon juice to clean up battery corrosion etc, as above the key is proper cleaning afterwards and then fully drying.
Depends on what's wrong with it. I don't know if James (Xian Xi here) is still taking some. If it's a simpler fix, more members can fix itResurrecting this thread as life derails you sometimes.
My Neo has been on the shelf for a while and definitely needs some TLC (clean solder work which I suck at) to bring this thing back to life.
I just got a RetroTink2X and would love to hook this AES up component to my big screen tv.
I've reached out to who I could find online but am asking the community if there is anyone here willing to take a look at this and do some work to bring it back to life 100%?
Thanks
