Compressed picture in the upper corners of my Daewoo DTQ-20U4SC TV

Hello, I have hope on you guys! My 3-year old Daewoo DTQ-20U4SC 20" TV is having a picture problem. At the upper corners the image is compressed like this )( leaving a black "triangle" in the corners. Does anybody know what is causing this problem? Thank you very much for your help. I feel I have such a bad luck.

It sounds like you have a "pin cushion" problem. There is a "pincushion circuit in your set that causes it to make a "square" picture. Some component in this circuit has failed. I am assuming that your set is the "picture tube" type--- not LCD or Plasma. You need to have a tech check it for you. Stargazer
