PROBLEMS WITH VERTICAL ROLL

Remove the LVDS connector. clean and replace, then the flat ribbon cables going from tcon to panel. If that doesn't help you most likely have a bad panel, you can replace the tcon but I don't think it will help

Format or color system incompatibility, loose contacts in cable, RC jacks or sockets. Connect a DVD player in that input and try.

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

Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER


Hoping this will help in solving the problem...

There is a capacitor in the vertical circuit that has significantly changed value causing this. If you are familiar with these units, look for a capacitor with the value of around 100ufd that is part of the vertical circuit and change it. That should resolve it. If you bring this to a shop, expect a parts cost up to $10.

Replace Verical IC and componets in same circuit maybe 2or3 bad capacitors. 100uf 35v ,1uf or 2.2uf 50volt. you need to order vertical Kit.

Somehow the TV setting on the DVD player was set to PALS so we changed it to the proper setting.

The problem may be related to bad capacitors on the PIP module. This is a commom fault as vertical sync runs through the PIP board and this is the symptom of the pip board having bad capacitors the TV rolls.

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.

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
