hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

There's a 'data control' and/or 'address' problem that's developed. Pixels depend on voltage, control, and data coming too their designated address.

A digital circuit feature called a 'DATA_ADDRESS_ BUS" are responsible for 3 criteria: Delivering voltage, control, and data to each pixel in less than a second.

1) If voltage fails the pixels don't light up. They appear black in color (their 'off 'state)....numerous pixels that don't light up look like a black line. But their actually individual pixels with no voltage.

2) If control fails then all pixels are white in color (their 'on' state). Without control the pixels can't adjust properly to high or low 'state', meaning brightness and dimness. This looks like a white line vertically on the screen.

3) If data fails then the pixels can't adjust to the proper color at the proper time.
This appears as a line that changes color out of sync with the entire picture.


Have a technician look at the pixel address registry circuits. As well as control and linear circuits....the problem is somewhere in there!

You can change aspect ratio by remote. I hope it will be solve

Are the solid horizontal black lines or colored lines. If colored lines there is a posibility that your Y-main, and upper and lower Y-buffers are bad. If black you have a bad plasma panel.
