Sorry, you can try reconnecting connectors on T-con board (small rectangle board at top center under metal shield)if you are lucky, but it is likely a panel failure. It won't hurt to watch it as it is, if it doesn't bother you

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

Green line down the middle of the screen

Often times this issue is caused by either a loose or damaged VGA cable. You can verify the issue often times by firmly wiggling the cable and watching to see if the line disappears. If that does not resolve the issue you will need to replace the monitor

first make sure it does not come from the signal. If its really from the tv and look like a darker line it can come from the lcd control unit but most of the time its a dfective lcd panel

Green picture

a green screen on power up with retrace lines. At shut down a point appears in the middle of the screen. Sounds like either a shorted G2 grid, or bad flyback. If a phospher flake has shorted the grid in the tube, you can sometimes have luck by using a megger set at 1000VDC, to burn away the short. This is usually caused by the line HV going too high causing the anti-UV protection to kick in so fit a dummy load 40W lamp instead to the line output to allow measurements to be made.

If the set is still in warranty, call for warranty service. If not and you feel comfortable working on the set, carefully open up the back and reseat all of hte cables and connectors. This can be caused by marginal connections inside the set.

Keep us posted on your progress and results.

Sounds to me like its your green tube. Kind of expensive replacement, but easy.
