Maybe you can try to play your DVD disc on a computer? 1. Insert your DVD disc with the disc drive. 2.Play the DVD disc with a DVD player software. There are many out the market you can choose from like VLC media player, 5KPlayer, PotPlayer, Windows Media Player, etc. If it works, then your DVD disc is in good condition. If it still doesn’t work, maybe there is something wrong with your TV and DVD player.
