copy / paste from my reply on the firmware topic :
ever since i updated to the last fw, my tv turned into a total piece of trash ,
although it was not working so well before the update but after that, it is completely useless i can tell you .
wondering how much longer we have to wait for a real fix ...
been facing this issue since may 2018 and it get worse and worse with any new update ...
plz fully test fw before u turn our tvs into a useless pos .
