Facing TV Problems? Ask a TV Technician.
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I will need to ask a few questions about the situation before I can offer advice, please:
Can you press the MENU button on the TV's remote, first of all, to get into the Menu system?
Have you made previous attempts to adjust the screen size or picture size, before this?
