Question about Mitsubishi WD-73837 73 in. HDTV
TV RESET USING CONTROL PANEL DOES NO GOOD.NO ERROR CODE.CODE IS 1-2.
Sounds like corrupted firmware. Contact any service technician. However, try a reset to this set, and check before doing a firmware update. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option.

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.

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.
