Thanks for your answer nfandres. The whole picture rolls up and down. In the old days I could fix it with a Horizontal or vertical hold button, but I don;t have one of those here. Any other suggestions? Thanks.

Re: horizontal roll on mitusbishi 35" tv
Is this a horizontal black line going up or down? if yes, this sympton is caused by a trouble in the integrated circuit or in the vertical oscillator circuit.
this symptons has 2 variations. one is the intermittent rolling of the picture. this referred to as the "loose vertical hold" the other variations is the continuous upward or downward rolling of the picture

This problems it pretty easy to fix.Just require take the tv apart.Resolders all the holes in the video board that connected to a long CRT tube neck.Should cost $50 -$75 more than that u are being cheated.
the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high current.you need a special setup to discharge the picture tube.
This sounds like a leaky electrolytic capacitor in the unit's video circuitry. You will have to take the unit to a qualified technician for repair, because there are no user serviceable parts inside, & the capacitor in question is about the size of a BB.
