This is indeed a repairable problem, and fairly common. I suggest you find a Technician though, as the back of the TV will have to be removed for the adjustment. On the neck of the Picture Tube is the "Deflection Yoke". This needs a slight twist after loosening a clamp only a few degrees. In most cases this will align the geometry problem. I would advise against doing this job yourself unless qualified as the high voltages used in TV's can be lethal.
Good luck, Peter.
HAVE TILT CORRECTION TO +5 AND PICTURE STILL NOT STRAIGHT.IS THIS A REPAIRABLE PROBLEM? IS THEIR AN INTERNAL ADJUSTMENT? VERY NOTICEABLE IN LETTER BOX MOVIES AND SPORTS TICKER TAPES.
