Is it truly TCL, at fault, or is it ROKU? or maybe they are in it together and it is both their faults? If the TV's don't fail, then no sales, no sales, no percentage. Roku, for anyone who has owned just their Roku boxes or Streaming sticks can tell you, after a few years, Roku comes out with a new Model, when this happens, Roku gives an Update for the older Boxes/streaming sticks, when they do so, depending on what box/stick you have, problems start to occur! They will load the box/stick down with so much junkware, that it tanks the memory so much, that it takes forever to load their apps, or the apps fail to load at all. Those of you having black screen issues, did you by chance do an update prior to the black screen nightmare? If so, within a short time period did the black screen of death occure? If so, great chance the update is what made your nice TV a a black screen nightmare! Is their a way to remove the update? could be, but chances are some or a lot of the apps will need the update to function correctly! Which means after update, your tv will go black again! My advice to you all is this. If you have to have ROKU! buy a box/stick and attache it to a Good product TV! Not another nightmare Roku TV! It is easier to replace a box/stick, and a whole lot cheaper, then Buying a all in one Roku TV, that is never going to last. this way you get best of both worlds, Just never do updates on any TV, just the streaming box/stick! That said never connect your TV to the internet! Because Just like Roku, These TV compines does the same thing they will give automatic updates to crash your TV's in hope You will buy another one from them! Updates can kill a good thing! and make one pay out their backsides for another. One last note! Just because your screen goes black, does not mean that all black screen deaths are the same, or did so because of update or something else. A thing I learned about those Who make TV's is, that Some of them will stoop so low as to but cheap electronic parts on their boards, so that their TV's will fail after a few years, in turn making you, unless you take it to a repair shop to fix it, buy a new TV, they hope from them! Is this aways the case why some get the black screen nightmare, no, sometimes just as someone repeats over, and over again, unpugging and wait and replug fixes the TV! that can be true, because as I said, all black screen issues is not caused by same issue! Regards!
