damyansi debana since you already replaced the power board (integrated T-con board) and you made sure that the backlight comes on, the only other thing could be a bad main board (after that it’s the panel and there is no replacement for that. You are 100% you have a good power board and you tested all your inputs to make sure that none of them worked.
