The Verizon FiOS set-top box acts as the control center for your TV service. Problems with the set-top box's configuration, the FiOS modem connection or other settings can disrupt the reception from your TV service. Reset the Verizon router and set-top box if the channels are unavailable to return your TV service to a working condition. Resetting the set-top box will not affect any of the on-demand titles, favorite channels or personal settings.
Check to ensure the coaxial cable in the rear of the set-top box is securely attached. Loose connections can disrupt the available channels.
Unplug the power cord to the Verizon router. Leave the cord unplugged for at least 15 seconds before inserting it back into the router. Wait for the router to reinitialize before checking your TV service. Reset your set-top box if the channels are still unavailable.
Remove the power cable from the rear of the Verizon set-top box. Leave it unplugged for at least 15 seconds. Insert the cable back into the set-top box. Wait for the time to appear on the front panel of the box.
Press the "Power" button on the Verizon set-top box to complete the reset process and restore the channels.
Contact the Verizon FiOS Customer Support if you need to reset your set-top box frequently.
