Default Re: Sony OLED TV 4 red blinking lights

could you show us here photo of one of them with this thin line ?
you can located it on the ribbon if its on No 1.2.3 or 4 and with tape hide the suspected line by measure how many line at each ribbon X4 and measure the distance of the line location on the nearest side of screen to know which line or at least with couple of line... then check if the set keep on with black line on screen
