Some time ago i got this Samsung as a not working tv to try to repair it, the problem was at the Y-main board, someone had tried to repair it before me and there was missing parts off the board including missing heatsink, i had few attempts at fixing the board but were unsuccessful so i got a new board from Aliexpress and the tv is now working but it has rally bad noise in the upper and lower parts of the screen, its especially bad in the upper left hand corner of the screen. Can someone tell me if this is fixable or the panel is done for. Thank you!
