65 in sharp roku tv turned off completely fine last night.. tried to turn it on this morning and it flashes SHARP roku in white/grey color but never completely turns on. The red light indicating it’s on flashes red as well. We have tried unplugging it from the wall for 60+ seconds and it didn’t help. Tried taking the batteries out of the remote and that didn’t help. Any ideas on how to fix this?
Have you tried contacting Sharp Customer Support to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
