Respuesta a "Why is my TV blinking?"I have a similar issue with a Samsung UN60J620DAF that was flashing the picture on and off on it's own, but sound remained. I ordered and installed a new LVDS and TCON board that match the serial numbers from the original parts. I installed TCON board and new LVDS, picture is back, but now the picture is blinking rapidly, slightly lighter and darker. Turned off ECO mode, reset TV, turned off, turned back on, updated software, checked TV source, HDMI source, and still rapidly blinking from lighter to darker picture. I ran picture tests but it's blinking during the tests. Someone suggested it may be faulty backlight strips, but I haven't looked at those yet. I also tried the original LVDS with the new TCON but the results were the same. I've also tried different power outlets with power strip. Any help is appreciated!
