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.

Why does the sky allways have a teal color ,the sky is almost never like that for real


You may have to halt or stop the light sensor as it may give false reading. If you have room lighting, you may have to turn that off. Lastly try to reset TV.
