Why does my sanyo flat screen TV have vertical coloced lines on screen with no picture?

Check the ribbons going in between the boards and "work" them to clean up all connections. And on the main board look for possible bad caps.

Your t con board is responsible for all picture distortions but not the vertical lines you described.

My Sanyo 50 inch tv has black line going vertically down , what can I do too fix this problem ?

Hello. I'm sorry, but lines in the screen, either vertical or horizontal, in 99% of the cases is not repairable without changing the panel. Some of the older TVs you could change a buffer or drive board, but those days are pretty much gone.

There are two possibilities.

Vertical line in center

If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.

Vertical line

Hi there!
This is called a frame collapse. The Amp that drives the vertical sync has failed. This could be from excesive voltage on the mains, Lightning in the area, if you had or simply general failure. May also be dry joints( or loose connections) in the vertical amp or scancoil terminals. Good Luck,JUS004
