A1534 Liquid Damage No Keyboard or Trackpad. Board damage?

[Melvinzill]

Hi got this A1534 12" 2015 Retina MacBook in for repair after a small spill over the Keyboard. My first ever 12" Retina I've worked on. The Keyboard is completely unresponsive as well as the Trackpad. I was first tempted to replace the top case as these are absolutely notorious for their Butterfly Keyboards failing, but all Keys dead and a dead Trackpad seem to me like it could be a board level issue.... Don't have a second machine to swap the to case with for testing at the moment.

Anyone ever seen this before?

If the spill was over keyboard, tou must start changing entire KB/TP assembly.
There is a complex electronic circuitry.
You can try to clean that small board; also check the flex terminals....
