Wasn't able to get the standard Sharp codes to work with this model. The setup prompts "do I want to setup the remote for the Sharp TV", so I beleive it is detecting the TV correctly. We have a similar model 43" Sharp Roku and the default Sharp code 10093 works just fine. I'm readling the Hisense makes these sets under licence from Sharp, so maybe I'll run through the Hisense codes?
Try 11756 or 11602 (11756 worked for me)
