Popping noises are not a good sign; I suspect the sound came from the catastrophic death of an electrolytic capacitor or worse, the death a a power semiconductor.Open the lower cabinet and using a good light, look for a smaller, separate board with fairly large parts on it; some cylindrical in shape, others block-like that may have copper wire showing.If, as common, this board is plugged with connectors into other parts of the system, you may be able to swap the failed board out for a replacement bought from a Mitsubishi service center.Expect to pay $100-$150 US if the set is no longer under warranty.

7.1 surround sound will not work with a coax connection OR Composite (yellow video with Red and White audio). You either need to use an HDMI cable or the Component connection (Red, Green, and Blue connection along with the Red and White audio or the optical audio connection).

I'm sure it's nothing you did wrong. I maybe a blown fuse inside causing the problem or a bad power supply. But, I wouldn't open up the TV. It may void the warranty by playing around inside.
Best to take it back and exchange it for another one. Tv repairs now and days cost an arm and a leg. Use warranty to full advantage.

The lamp is not enabled possibly due to the colour wheel motor not turning. Any broken glass jamming it? Or the lamp ballast has failed due to an old/worn lamp.
