Samsung Plasma TV Rescue - PART 1 to 4

I found an abandoned Samsung Plasma TV PS-42S5H on the roadside, and decided to see if I could rescue it. 

The TV was in a completely unknown state, along with its remote control, so I had to do a complete troubleshooting cycle on the TV and its remote.  

Watch as I systematically move through the stages of troubleshooting towards an (ultimately) successful resolution.
