Sometimes a large black rectangular area appears on screen and will go away for a few seconds if I push the volume up or volume down button. Turning off the TV for a few seconds doesn't seem to change anything, but turning the TV off for several minutes usually makes the prolbem go away. Any suggestions?

Sorry, but I don't think a shorted yoke could produce this symptom. The symptom is not a diagonal line, but is a large, completely filled-in black rectangle that occupied approximately 40% of the screen area. the black area dies not extend to either side, nor to the top or the bottom of the screen, and is mostly in the bottom half of the screen.
