How do I get rid of black square on curtis mathis tv?

try this first. go to menu, setup,close caption,make sure your tv is not set on text, if it is uncheck it. this will cause your problem. If text is not check then your tv is in child lock mode.Go to program,child lock,you will have to enter three numbers to unlock this ,If you have forgotten code enter 777 this will erace key numbers. hope this get you going again.
