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

Start by confirming the circuit is hot at the wall. Plug in a lamp or something.
Try your generic cord with another device to eliminate it as a variable.
What sort of cord is it?

if you type in your model number on the internet there is a web site that comes up specifically for your model. they are not difficult to do, i hve done my one and I fed all the wires through the leg of the fire surrond.

If you do not have a fire surround the cables can be burried in the wall

You usually have this type of lines when there in a problem with the frequency or voltage.
Can you be more specific as to whether this problem is there always or when u use something specifically with the tv(like vcr, cable, etc..)

i have a white line vertical in the midle of tv

I think what has happened is that your power supply malfunctioned and what has happened is that a capacitor has blown up. I would suggest that you do a complete search of the power supply to determine the location of the blown capacitor, I would advise getting a schematic to aid you in this. If you don't have experience in electronics I would also advise taking the set to the shop or calling a repairman to take care of this issue.
