If you understood my last post I said I didn't use the secret code. Someone else posted that and another tried it and said it worked. Why don't you try reading the posts. It's not my fault you broke your tv probably monkeying around with it.
It's been 4 MONTHS! I see "rokudanny" took it upon himself to close an unresolved thread merely saying that are aware and it would be fixed at some point. Shame on this company. If you think this is an OK way to treat customers, power to you. Everyone else, dump this garbage, recommend against roku, block all their ads via blocker dns services, router settings, whatever you can. This company burns through half their warranty period before fixing active issues.
i think meter for signal strength is giving incorrect information on antenna, i have tcl s525 roku tv 43 inch, the picture is normal with no issues, the meter is incorrect. Just ignore signal strength meter for OTA tv.
