Your Emerson TVs LOT [Line Output Transformer] has damaged. It should be replaced with same type and number. Before replacing it, first repace the horizontal output tansistor. This transistor can be located very near to the LOT, screwed onto a metal heatsink, and a black three terminal component. Replace it first, and switch on your TV for a short time, say 3 to 5 seconds, switch it OFF, unplug it from the mains sullpy wall plug, and check the heat of the transistor, by touching it by bare fingers. It may be slight warm but not too hot. If it overheats, make sure that the LOT has damaged. OK.

There are two methods to reset 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 is 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. If you wish to get some details; check the site linked here. Pull up older posts.
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

Had a friend that had the exact same problem. If it is still under warranty you should take it down to a dodge dealership for a dashboard replacement.
