There seems to be some confusion as to who responsible for what when it comes to the "Smart Televisions". Roku puts their software in the back of almost every television made these days. It allows you to watch some free content from the Internet (like YouTube) on your TV, as well as subscription content such as HBO, Netflix, and Hulu, and Sharp (in my case), and other major brand televisions put in the rest. The "rest" in this case is the "power-boards" and "main-boards", which turns the televisions on and off and control things like the "light-strips" that are needed to provide the picture. I have spent months and months researching this mess as I tried to fix my Sharp 58" Television, and this is where things get even more confusing. Apparently Roku doesn't care about the fact that they are tied in to all of this because all they will tell you is to unplug the TV for 30 seconds and all will be right with the world, when in fact in the vast majority of those posting here know that it wont work. And if it doesn't work, Roku's response is "Call the television's maker". Again, in my case it is Sharp, and if the TV is past its 1 Year Warranty, all Sharp has to offer is "Good luck, we cannot help you". If one thinks (like I did) "Well heck, I'll just order the boards and replace them myself!" That's a great plan because anyone with a screwdriver can pull the back off and replace the bad board... BUT THINGS GET WORSE ON THIS FRONT. There are several "power-boards" and "main-boards" that will fit in the back of the televisions (as I found out), but only certain ones will work with the rest. For instance, if you put in the wrong "power-board" that don't get along with the "main-board", in your television or vise versa, nothing will work (I found this out as well). The boards in the back of my TV are marked with the Sharp name, but that does nothing to negate the "board" compatibility problem (i.e. different size screen seem to have different boards within any given brand name. I, too, own a Vizio that is still running strong after years of working without a single problem. It irks me that this is happening again and again, and nobody from the television makers or Roku (who also make some of their own televisions by the way) will come forward with information on how to fix their televisions that people paid good money for, only to have them go bad in 13 months, which is almost to the day when my Sharp/Roku went dead while I was watching it. Like everyone else, this didn't make me a happy camper, and I will do my best to never purchase another Sharp/Roku television, or any television that is made at the Hisense plant in China where it (and many others) was made.
