I recently bought two Onn tvs and connected the first to my Samsung tv, no issues but my second tv is a Blaupunkt and isn’t listed on the screen for the remote setup, so I can’t control anything with the remote. I thought Blaupunkt would be a well known electrical brand. Is there a way to get this setup anyway?
I didn't know Blaupunkt made a TV.
Safe bet that it is a rebranded some other tv maker. Try and look up who actually manufactured the TV, and use codes for that base model. Make SURE CEC is enabled. Does it have an eArc port?
