In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

How to decrease the width of the tv screen
I am not familiar with your particular TV but I have sets from 3 different makers that all handle the problem you describe a little differently via the remote provided with the TV. One uses a Format button that allows you to go through each picture type as you press the button until you find the one you like best. Another has a Pic Size button that uses a pop-up menu that allows you to use the arrow keys to scroll through each type. The last one and most limited in choices requires you to go into the Menu from the remote and make changes through Settings or Setup to change the picture. Hopefully this may help.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

How do I get my TV to reset it is a 47 inch flat screen
Sounds like fault in its main board. 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. 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.
