Just bought a 1994 50" Mitsubishi Model # VS-6071. When I bought it worked fine once I got it home and set up that was a different story.... The picture comes on but has picture rolling.. I have the orignal remote but not sure how to work it yet. Is there anything on the remote that will let me adjust this??? I know some models have a Vertical and Horizontial knob on the backs that you can adjust didn't find any on this one... Anything anyone?? Or do I need to call a tech in to fix it?? I didn't pay that much for the TV so not sure as to how much more I should spend?? Thanks...
