Vertical line down the screen about 2 inches thick


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

HOPING THIS WILL HELP TO SOLVE THE PROBLEM....

I have vertical colored lines and cant read menu on my l32w761 envision lcd It seems to be shutting its self off also and the light blinks an orange color in place of the usual green


Hello,

On all the plasma tvs there are control boards on the lower part of the screen that control the vertical images. If one of the chips on one of the boards fail, have a bad connection, or no ground it will result in a thick black line down the screen.

Tv is about 4 years old. Suddenly developed two


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.

Vertical Line started on left side of HDTV, and now


This problem is down to the actual LCD or plasma screen, if this shows as the screen warms up and stays on then the screen will need to be replaced, you should go back to your retailer (not manufacturer) and report this problem, depending on the store and how long you have had the tv, the tv can be replaced for a like for like tv at store as this is not a cheap standard repair.

Black line on plasma tv


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

Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use


On al the plasma tvs there are control boards on the lower part of the screen that control the vertical images. If one of the chips on one of the boards fail, have a bad connection, or no ground it will result in a thick black lne down the screen. Seeing as the tv is new I would get the warrantee repair on it. There is a possibility that there is a problem with the screen itself but more than likely its the boards.
