[mythtv-users] Report: Watch out! UB435-Q V2 is NOT the same as UB435-Q

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.
