Good day everyone , i need some help with my tv Here's the case my tv suddenly went a little bit dark than before right after i accidentaly update the software at first i suspect it was the update that causing this but after a friend of mine put my mainboard into his H6400 tv with the exact same picture setting as mine and surprisingly the screen are very much bright its not dark at all after that we wonder if its not the mainboard then which part that has a high possibility creating this issue

What do u guys think? is it the T-con , Psu , or Panel? Thx

What we want is a photo of the picture you see on the TV screen. Post this up as soon as you can. Then we would know better what we are dealing with. Thanks.
