CTC187AB; I forget how to access the service menu in this set. I have a vertical height problem (pic streched top to bottom). I touched up the tuner grounds and posts (was needed)but picture remains the same. I would like to view the vertical setting, but forget the button sequence, unless this chassis requires the PC hookup.
