SOURCE: PROBLEMS WITH VERTICAL ROLL

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

SOURCE: Picture is Rolling..stops after some warm-up

I have seen this many times. There is a 9 volt regulator on the small signal board that causes this. The regulator goes bad and the 9 volts starts dropping, especially at start-up when the regulator is cold. If the voltage is below 8 volts then the picture gets dark and the vertical becomes unstable, with the picture squeezing down and/or rolling. As the regulator warms up the voltage starts rising back towards 9 volts and the symptoms start clearing up. There are 3 regulators in a row on the board and the regulator in the middle is always the bad one. Replacing that regulator should cure your problems but it should be replaced by someone experienced in servicing Mitsubishi projection TV's because pulling the chassis out is quite tricky.

SOURCE: Rolling picture

Not likely. They probably just need to be cleaned and re-alligned. Rates vary, but our shop charges $20 to do that.

Why my telefunken picture keep on going down not stable?


Vertical rolling. Instability in vertical sync: circuit. Contact any service technician. Sounds like an IC fault. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Tv roll


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.

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.
