Hello my brother had purchased a 55" insignia fire tv NS-55DF710NA21 june2020 date manufactured and less then a year it stopped powering on the red light powers on solid red or slashing but the screen doesnt power on. It has a direct power plug same with a 2012 emerson 320 tv the sqaure red indicator light stays on but when power button is hit the screen doesnt come on. What is usually the problem with these? The 55" power button does make a random crackling noise around the power button sometimes when pressed or randomly. Ive tried leaving them unplugged for days and still just the red light but no screen will come on as well as holding the power button with it unplugged to discharge any stored energy.
