This seems to be a common issue observed by many Hisense manufactured Sharp TVs and it started happening effect Wednesday, Mar 30th, 2022. My TV model is 2018 purchased during Thanks Giving Day.
It was playing fine and it went all of a sudden starting this day. I doubt on SW update issue.
TV boot image works fine to bring up the logo but it appears that it does not find Roku Software load on the main SoC, hence fails to bring up the Roku application that shows up system menu ( Roku TV applications)
The root cause of this could be 1) corrupted software or 2) Some hardware issue.
I want to check 1) if it's due to wrong update. Can I try USB based image for boot software to load the correct image? Can someone give me what is the best firmware for my model?
I contacted Hisense customer care (1-888-935-8880), he suggested that Roku owns/delivers the software for my TV, hence i should be looking for Roku support team for this help. Can Roku take the responsibility?
