Question The TV looks like the vertical hold needs adjusted. The picture keeps rolling and there is a white line that constantly rolls over the screen. My husband tried to the antenna without success. What do you think and where can I find the vertical hold? The screen is clear on the DVD player Thank You
Answer On most TVs they replaced the old back knobs for vertical and other adjustments by hidden menus intended for the installer.
You usually reach them thru a sequence of buttons pushs.
I am not familiar with this TV in particular and I do not know the sequence.
