|The RC00161P seems to be the remote and not the TV. Most TVs have several different input options--antenna/cable, DVD, maybe an AUX. Maybe you unintentionally changed the input to something not connected when you clicked the down arrow. I'd check things like that first. TVs have gotten a lot more sophisticated than the black and white RCA Victor I watched as a kid. You may need to consult its manual.|
If you think the remote is the problem you can pick one up on ebay.
Also check things like cable connections. Maybe unplug the power cord and plug it back in.
