I just cracked my KW-UB435-Q V2 open, here's some of the chips I identified:
Surface mount chips with many leads:
Labelled as a "7th generation tuner": LGDT3305
A very big chip (big here means 9mm square): NXP / TDA18271HDC2
Small chip on reverse side: CeMPIA / EM2874b
And that's it for the microchip looking things on this device. There's a
few larger items that look like voltage converters or transistors, and a few
crystal looking things. I don't know much about electronics.
