On and off commands come from the main board, if it won't shut off you need a new board

Please follow guidelines in operation manual, step by step.

Hello
Check the remote first for its infrared emission. If it is OK, the infrared sensor inside your tV is faulty. It should be replaced with same type and number. It can be located just behind the infrared window at the front panel of your Tv. You ahve to open your TV ot access it. It will have three solder terminals, and will look somehat brownish black in colour. Will look like this.

You can reset your remote control by removing the batteries, pressing all of its buttons, and installing new batteries. Also, ensure that your TV's sensor is clean and unobstructed. If the problem persists, try using a universal remote control as a troubleshooting step. This will help identify whether the original remote or the TV is at fault.

With the remote in TV mode, the input button on the remote should change the source (TV, AV1, etc. depending on the TV).

If the input button doesn't work, try a different code for your TV manufacturer. A code that controls the basic functions of the remote may not control the full set of functions of the TV. For some TVs, you can change the source from within the Menu. (It depends on the TV. I didn't notice if there was a Menu button that will open the TV menu on the RCA RCU600M.)

If none of the codes work, check if your TV has a Source or Input button on the unit. See if that button works.

If you have a different remote, please indicate the model.

I hope this helps.

Hello
You might have a cellphone with camera option. Set the cellphone co cemera mode, and place the remote control at about 1 feet away from its camera lens, and press each button on your remote control. Remote control emits infrared rys as we press each button, but can't be detected by human eye. Electronic cameras can detect it. If there is any infrared ray emission from your remote control you will see its image on the camera screen for each button press to your remote control. If there is image and still the Tv doesn't respond to it, The TVs' infrared snsor inside has damaged and should be replaced. If there isn't any image; check the battery contacts of the remote battery compartment first. Clean these contacts by using a piece of corborandum paper or with the tip of a razor blade. Improper battery contacts, due to rust and dust to these contacts will prevent the battery supply voltage to enter into the remote contro.
Still it doesn't work at all, the remote control is damged and should be replaced. Contact the nearest Vizio Authorised Service Cente fro original remote control. OK.
