Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Can you tell me the full model number of the tv (Printed on back)?Also are you using just a basic cable feed (cord from wall to tv directly) or is there a cable box being used?
this is going to be a comcast issue then, meaning a function of the box.
Grab the comcast remote (not lg remote) and look for a CC or subtitle button. If you don't see that go into the comcast menu and you should find it there in the options.
