Hello Wgodfrey,
No, I never did get my 58" Sharp/Roku television working again. I tried everything that I could find online to find the fix. I had purchased an extended 3 year extended warranty when I bought the TV. When I called to get my money back from "SquareTrade" (a division of Allstate Insurance who handles claims such claims), the agent had me go thru a series of 'resets', all of which I had tried before. To no surprise, this all proved fruitless. She advised me that the main board in the TV had gone bad and she issued me a refund check. (This process was extremely easy and the check arrived in the mail three days later.) Working off that info, I opened up the back and got the correct part number off of the main board. (To add to the hassles, there are several different boards of each of the 3 types in the back that will only work if all 3 match one another.) I ordered the main board online on installed it, only to be disappointed again. At this point, I have a 58" television that is sitting against the wall, and nobody from Sharp/Roku will tell me what I need in order to be able to watch it again. They cannot tell me that nobody at that company has the answer to exactly what part I need given the the information about the dimming red status light. Unfortunately, almost every big screen TV on the US market these days have Roku garbage for their guts, but they won't give that out because instead of buying a new, $500 television they could be fixed by anyone who knows how to use a screwdriver for less than $50. It is a total disservice to the American public who had put our faith in these "name brand" televisions for years, and that stinks. Sorry to be the bearer of bad news, but this has been a three month journey for me that has ended in disappointment over and over again. THANKS FOR NOTHING SHARP AND ROKU!
