I bought my ROKU TV from Walmart in 2018
Sharp 65? Class 4K Ultra HD (2160P) Roku Smart LED TV (65Q7300U)
First I contacted SHARP support to get the firmware, they sent me to HISENSE, then HISENSE asked to contact ROKU.
TV keeps restarting. Any solution would help. Is there any place to get the correct firmware?
Dont know if its too late... I'm currently at work and just came across this.. I have the exact same problem... going to see what this does.
