Vertical IC, caps or the hyper board would be my guess. None of which you can do yourself without some serious electronics experience. You'll need to ESR test the caps in the vertical circuit first, then move-on to static testing the vertical IC. If either of these are the problem it's not too expensive. The Hyper Module is a different story, usually only replaceable as a module but you can also send them in for rebuild to PTS Electronics.

Yeah I have a Sylvania model # SP A2751 106. It is a old **** tube tv. When I go to hook up the the dvd player and switch it to vcr/aux the picture rolls in bars upwards. Its not the dvd player tried it on...

There should be a preset resistor on circuit board of old CRT based TVs, designated as vertical rolling adjust. Try to locate it and adjust a little till rolling stops, while playing the DVD. The set will be live during this process, so be careful. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact any experienced service technician, or the nearest service center.

The horizontal hold

If model number correct (the one posted here) set does not have a horizontal (rolls left to right) or a vertical (rolls top to bottom) control.

Verify model and brand so I may offer some suggestions

Video tapes played through VCR experience vertical 'rolling'

unfortunatly no. the vert hold is set by black bars at the top/bottom of the video signal (outside of the viewable area). it sounds like your VCR or tape is damaged.

Vertical rolling of picture

If the picture rolls while both on cable as well as when you playback a tape or DVD, it could be caused by a bad filter capacitor in the power supply or vertical deflection circuits. If it only rolls while trying to view a picture from a cable/satellite box, then that component is likely at fault.

i know this may seem old-school, but try turning the vertical hold knob. it used to solve all vcr problems with rolling picture.

That is not a vertical roll from side to side, this is a horizontal rolling. if the vertical had a roll it would be going from top to bottom. This is most likely a coupling between the horizontal sync circuit and the sync separator circuit. Good Luck
