Vizio Remote Teardown

One day, my friend genpfault came over to build some model aircraft, and for various reasons we decided to teardown my television remote.

The external frame consists of a front and back face, a battery door, and two button grids. The front and back faces are held together with snap clips that are easily opened with a plastic butter knife or a spudger.

Inside we find two PCBs connected with a single power cable. each PCB has its own power filtering capacitor, but as we shall see in a few photos, this is a very simple design.

Remote PCB. I suspect this may be shared with my non-keyboard remote.

Keyboard PCB. This circuit is entirely separate from the remote PCB, except for two wires providing power.
