Usually, a color TV needs only slight touch-up adjustment upon installation. Check the basic
characteristics such as vertical size, horizontal size, and focus. Observe the picture and check for
good black and white details. There must be no objectionable color shading: If color shading is
present, demagnetize the receiver. If color shading persists, re-do purity and convergence adjustments.
