Re: samsung qe55q7fam no picture
You've got 2 problems, bad ma.bo. settings programming, and bad gate driver on panel, first try to swap 24c eeprom from old to new board, then turn on and keep exit key pressed for about 15 sec, then turn off then on and pray for the image to be visible, next step coming soon..Last edited by Davi.p; 08-29-2022, 06:09 PM.
