A:AnswerThis DVD Player is very user friendly. It is easy enough for ages 8-80, or in your case 90. My 7 year has no problem turning on and pressing play
A:AnswerI really can't answer your question since we didn't have any issues with the product. Only suggestion I would have is to try a different DVD or double check all of the settings. If it's newly purchased then I'm sure someone in customer service would help figure out the problem
