On my KD-43XD8305 at a time , when I watched a football match , the image has become distorted , appeared complementary colors and a grid with horizontal, vertical and tilted colored broken lines . I shutdown the TV from the remote control , but after I restarted it , there was no picture , only normal sound . The TV performed the boot procedure without displaying the animation and Android logo . LCD panel has backlit only and was light gray . I made the shutdown procedure , removed the power cord for several minutes and restarting several times , as it is specified in User Manual , but unsuccessfully . The front LED was lit normally , with no red or orange error codes and blinked only when a command was made on the remote control . It was possble to switch TV channels , adjust audio volume , but screen still remains black without image or informational banner . Two weeks ago , the TV successfully made a firmware update to version 6.2858 . What has happened and how can I solve this problem myself ? Is it a software problem (maybe a cyber attack , because the TV is always connected to the internet) or it is a hardware problem ? I understand that the Smart TV with Android TV OS can be attacked by viruses and malware , which can cause them serious problems . Has anyone ever encountered such a problem ? Thanks !
