Hi all,
I have a Samsung led Tv model UE405300AW. Some time ago it started to smell like burnt plastic and it started to show the "smart tv" pixeled icon without receiving any remote control demand. After unplug, opening it, I detected that one led was burnt, I changed entire led bar, but after I had no image but all leds working, including the remote control (for ex. I was able to hear the volume sound modification). At this point decided to search the runtk, and by error, did a shunt, and I lost the volume sound... Finally, changed the runtk and mainboard, but in the end I still have the same problem after changing the led bar: I have remote control, backlight but no image, I have sound of volume changing but no image... Some advice?
