TV is showing "No Signal"

Hi


Thanks for using FixYa. Two things that will cause the “No Signal” message to come up are - no data available for closed captioning and a weak signal input. With that being said it seems that your TV is in the Closed Captioning Mode. To turn it off simply bring up the on screen menu and scroll down to the part that says closed captioning and turn this function off! With the closed captioning block displayed and the program being viewed is not sending out closed captioning signals the TV will display, No signal! Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee
