What channel does my TV need to be on to play a DVD?
DVD players will display on one of the Input or Auxiliary channels. They will not show up on Channel 3 or 4 like some VCRs. Some TVs will label the Input channels based on the type of input, such as "HDMI", "AV", and "COMPONENT." Refer back to Method one if you have a question about which input type you are using.
What do I do if my DVD player won't read discs?
Remove the disc from the DVD player. Use a lint-free cloth and some denatured alcohol or water to clean the disc and remove any dust or smudges that may prevent the player from reading it properly. Reinsert the disc into the player and press « Play » to see if cleaning the disc fixes the « NO DISC » error.
