Line, faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent.

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

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.

Thanks.

the power supply is defected a capacitor filter is leaking.have a tech repair your tv.good luck.

does this only occur with one input and/or does it occur when using HDMI/component cables.

if so, try getting a new HDMI cable. I have the same problem with PS3...and im about to order a new HDMI cable.

This is caused by dead pixel sensors. There are hundreds of pixel sensors at the edges of the screen, when they go out it will cause a line varying in size depending on the amount of sensors that go out, and the line can vary in color, red, blue, green, white, and black. Unfortunately, the only fix for this is to replace the screen.

If these are thick black lines, this is most likely line frequency noise entering the set. you may have a leakage from the DC ground on the secondary side of the powersupply to the AC side, or a bad filter capacitor(s). Most of the time it is the filter caps that give these types of problems. If you are connected to cable TV service, or an outside antenna you can also have this problem from an AC ground loop return. Also if there is a device such as a VCR connected to the TV and it has problems, it can cause this as well...
