Vertical rolling of picture

this was adjusted by the fine tune on the selector It is the picture not being held in place by being out of tune Same as if the picture goes sideways On the real old units there were 2 knobs to make these adjustments.

The rolling is a bad filter capacitor on the signal board in the set---Any Mitsubishi dealer can look the model up and see known faults including this one---some of the sets when cold---vertical jitter in picture or just menu---If the menu is stable you have a tiny bad cap= weak caps when cold act up and when get hot regain capacitance and start to work.

It could just be a resistor or two ,

check for Vert Oscillator Circuit & AGC

Standard CRT televisions have a vertical roll adjustment,usually on the back at the bottom.
It may look like a white finger-knob (about the size of a pencil eraser) with a small screwdriver slot in the end...or it may be a roll-wheel...either way, it will be labeled "vertical" (or just "vert").

Make slow adjustment to the vertical until the roll stops.

*Use a solid signal for the adjustment, like DVD, VCR or cable...a weak signal can cause a bit of roll, too.

this fault is caused by defective electrolytic capacitors in the vertical deflection circuits, they need to be changed out, do this before it causes more problems, there are no adjustments for this anymore.

The sync is automatic. There are no knobs to turn. If the picture is rolling, look first to the source connection and make sure your tv has a solid vertical sync connection. If you are using the RF input then the issue could be within your small signal board also known as the SSB. Good luck.

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.

no control over the remote..but impossible not to have vertical hold control in the TV itself. it should have one maybe at the back.

Are you sure the roll isnt Vertical? as if it is then all you need to do is adjust the VERTICAL HOLD PRESET POT which should be located on the PCB somewhere, its very unusual for TV.S to roll horizontally as then the picture just goes out of sync. and you would not see a picture at all. When you find the pot turn it ( with a small screw driver) slowly until the rolling stops, if it does not stop then you have a faulty component in the vert. sync. circuitry.

many older tv's had a vertical synch adjustment knob which would correct this, but I doubt yours has one thats accesible without opening the case. If you decide to open the case, be very careful of the flyback and other high voltage points, even when it's unplugged. possibly there will be a trim pot on one of the boards silkscreened V SYNC.
