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.

I assume this is an LCD tv that you have? I would think a fault has developed on your inverter board with one of the components having burnt out & shutting off the drive to the backlights hence the smell & lines on the picture. It would be advisible to take it to a repair centre to have it repaired to check the burning issue as a matter of safety

Locate the button on the remote that came with the TV labeled "ratio" or "wide" or " format" not sure what yours is labeled different brands call it different things, but press it multiple times until you get the picture the way you want it to look.

Hello, it sounds like you need to replace the inverter board on this unit. I would recommend opening the unit from the back cover, get the part # for the inverter board (long green board normally running accross the edge of the TV) and go to www.shopjimmy.com, they should have it in stock and if not you can try www.invertercentral.com, they should also have it.
