Sceptre U550 (And likely others) direct input codes figured out!

After some fighting with my U550CV-UMR and my Harmony system I got all the direct inputs figured out and wanted to pass along my findings.  If support can add this functionality to the IR database for some of the Sceptre TVs I think it could save some people a lot of frustration.

If you want to get these codes now, ideally you'll have access to two harmony systems so you can just learn the IR codes into your Sceptre TV device.  Otherwise you'll have to settle with having these buttons as part of an activity to call the correct codes. Start by adding a new device to your configuration and use the Sony model(s) I've listed below, you really only need the 'KDL-55XBR8' model unless you want access to direct input for HDMI4.

Here are the Sony models with the needed IR commands, and then the mapping of the Sony name to the function on the Sceptre:

--------------------------

Sony KDL-55XBR8 :
Input PC -> HDMI3
Input Video 1 -> TV Tuner
Input Video 2 -> AV
Input Video 5 -> HDMI1/MHL
Input Video 6 -> HDMI2
Power On -> Discrete On
Power Off -> Discrete Off
Picture -> Freeze Image

Sony FWD-50PX2 :
Input 1 -> HDMI3
Input 2 -> HDMI4

Sony XBR-55X900E :
Audio -> MTS / Audio stream select

--------------------------

Of note, that FWD-50PX2 is a monitor but it's one of the few Sony devices I could find that has a 'RGB 2' input which is what HDMI4 is mapped to.

For the engineers in the house, these are all Sony12 protocol, Device 1 OBC Codes.  Functions: HDMI1=72, HDMI2=73, HDMI3=67,HDMI4=68,TV=64,AV=65,YPbPr/Component=69,USB/Media=99

And if Logitech engineers see this, please fix the dash button for my model at least!  That's the same protocol and device as above, function 32.

If you have access to a tool like IrScrutinizer then you can easily pull up all the functions for that protocol and device, there are plenty of other codes in there that aren't implemented but I think the most desirable ones are the discrete power and input codes I've listed above.
