I'm having trouble getting the closed captions to display on this TV. It has a few different options. It says "Caption Service' and then lists CC1, CC2, CC3, CC4 AND TEXT1, TEXT2, TEXT3, TEXT4. Another option is "Digital Caption Service" and then lists Service1, Service2, Service3, Service4, Service5, Service6. My husband and I had the settings at CC1 and Service1 and it worked, but only on one channel. Do you know where is needs to be set to have the closed captions work on ALL CHANNELS? Thank You
