For the white static/images, it is likely that the cable/sat box needs a calibration or a reset. The information in those lines are being sent directly to the television.
Is that happening on one channel only, or several?
As for the scrolling lines, it may be part of the box calibration settings, but is likely a setting in either the aspect ration of the cable box or the television.
A 16x9 picture output from cable box into the 16x9 setting on the television keeps the native resolution from souce to screen.
A 4x3 picture output from the cable box to a 16x9 setting on the television changes the resolution and can distort the picture. Same for vica verca (16x9 cable feed transferred to 4x3 on television).
The Wide View may be causing the issue, and changing that aspect ratio may give you the full picture.
Keep me posted!
