Most television sets broadcast error codes that include text to explain what's wrong. RCA doesn't have a list of such codes, but instead provides troubleshooting codes for its customers. When you have a problem with your RCA television that's not accompanied by an error code, you can troubleshoot by entering codes into your remote control or changing the TV's settings from its menu.
Front Panel Buttons
If the front panel buttons on your RCA TV don't work, they may be locked or disabled. You can unlock the buttons by pressing the "Menu" button on your remote and selecting "Parental Controls." If you have Parental Controls set, you must enter your password before you can reach the Parental Controls menu and select "Unblock" or "View," based on the model. To enable the front panel Menu button, you can use your remote control to go to Parental Controls menu, select "Channel Block" and then select "Off."
If your RCA TV has a picture but no color, or the color isn't right, you can fix it by pressing the "Menu" button on your remote, selecting "Picture Quality," and "Picture Controls." The arrow buttons on the remote let you change the brightness, color, contrast, tint and sharpness of the TV picture.
If you can't select the "Picture Quality" function or your RCA model doesn't have that menu option, you can press the "Menu" button and the Channel arrow buttons to select "Video," and the volume buttons to change the settings. If this doesn't work, pressing the "Menu" button repeatedly will help you reach the "Adjust" menu. After pressing the "Channel" button to highlight a picture setting and the volume to adjust it, you must press "Display" or "Clear" to leave the TV's main menu.
Guide Plus System
Some RCA TVs utilize the Guide Plus or Guide Plus+ Gold system to display cable TV channels and what's playing. If your system has the wrong list of channels or incorrect programs, you can select "Guide Plus+" from the main menu, followed by "Setup." After replacing the current entry under ZIP code with the code "99999," RCA suggests exiting the menu and turning off the TV for 10 minutes. When you turn the TV back on, you must return to the Guide Plus setup and revert the ZIP code to the correct code for your home address. Following the prompts on the screen will allow you to verify the accuracy of your cable programming.
Missing Cable Channels
If you don't have Guide Plus on your RCA TV but you're missing cable channels to which you've subscribed, you can fix your cable settings by pressing the "Menu" button on the remote before selecting "Setup" and "Auto Program." After selecting "Source," you must enter "Air" for over-the-air broadcast signals or "Cable" for cable TV. If you select "Auto Program," your TV will automatically go through the channels to discover those that you can watch and program them into its memory.
