Solved my RC73 Remote Program for SHARP LC-43Q3000U TV using Hisense Codes
I tried the Hisense codes at the recommendation from another member for our new Sharp 43Q3000U TV we just bought from Sam's Club and the remote was programmed to support the TV on the first attempt. Evidently, Hisense is manufacturing TVs for Sharp Corporation.
Press MENU on your remote.
Select Settings & Help > Settings > Remote Control > Program Remote.
Select/Type (HISENSE) as the name of the device you wish to control with the remote.
Select "I don't know the model number"
Test the first code by adjusting the volume and see if it works (my TV worked on first code)
I SPENT ALL DAY TRYING TO PROGRAM MY NEW SHARP TV TO THE RC71 REMOTE AND EVEN WITH THE TECH SUPPORT IT WAS UNSUCCESSFUL . THE TECH PERSON TOLD ME THAT SOMETIMES THE TV AND REMOTES ARE JUST COMPATIBLE, ESPECIALLY WITH SHARP BRAND TV'S. SO YESTERDAY I DECIDED TO MAKE ONE MORE ATTEMPT AT CALLING THE TECH SUPPORT CENTER BEFORE RETURNING THE TV TO BEST BUY AND I FINALLY GOT A TECHNICIAN THAT NEW WHAT SHE WAS DOING. SHE TOOK THE TIME TO GOOGLE SHARP TV'S AND PROBLEMS WITH PAIRING DIRECTTV REMOTES . THE SOLUTION WAS SIMPLE . APPARENTLY SHARP IS NOW OWNED BY HISENSE. SO INSTEAD OF ENTERING SHARP WHEN IT ASKS FOR THE TV BRAND YOU ENTER HISENSE AND THEN CLICK ON "I DO NOT KNOW THE MODEL" AND THEN PRESS CONTINUE AND IT PAIRED ON THE VERY FIRST TRY . I JUST WISH ALL OF THE TECHNICAL SUPPORT TEAM COULD BE AS GREAT AS THE LADY I HAD YESTERDAY.
