un65ku6290fxza samsung 65 inch from 2018.
TV stays on fine unless you press a button on any remote. Volume, channel, pause, settings, etc. The TV turns off then on again. The red light, standby light flickers/flashes rapidly.
Called Samsung and they said it needs to be serviced on my dime after 20 months. :-(
