LG 55 inch tv vertical lines, ive replaced the t-con board and cleaned the ribbons with use of an eraser and the lines continue, what is next thing to check?

The TV is about 15 months old so just outside of warranty and ive pulled it appart and cleaned the ribbons attaching to the tcon board with use of a new pencil eraser and reattached and the lines still continue, The lines seem to follow the color that appears on the tv.

LG 55LM4600-UC LED TV I have was squirted with a squirt gun. Would replacing the t-con board fix this tv? Please read further details.


when water shorts out something it overloads a lot of other components so the best advice is to take it in for a proper diagnosis.
you just replace a board but another board is damaged it might just blow the board you replaced and that would prove nothing

I have vertical lines showing up , I opened up the tv and I wiggled the connection ribben between the t-con and main board and the lines seems to be better but not 100% fixed what you suggest me to do?


Try one more thing, remove all the connections to t-con board the and clean the terminal of the wire. you can use an eraser for that. with the eraser rub the contacts on the end of the wires. do not use eraser on the sockets which is on the boards.you have clean only the wire. after cleaning connect it back and check. if then also the is lines there is line then you need a new t con board. There is also a chance of panel fault but it can only confirmed by replacing the t con board.

A black line running verticall down the middle of


There is no invertor board on a plasma tv. The fault is the X address buffer board. This is located on the bottom of the screen and runs horizontally the whole width of the screen. If you remove the heatsink plate that covers the x address boards and you need to look at the screen ribbon at the same position as where the bar is (in the middle).Vary gently lift the Xbuffer ribbon lock and gently take out the ribbon.Clean the contacts very carefully with a fibre pen or an electrical cleaning fluid.Insert ribbon back and heatsink and check.Here is a picture of the board and ribbon

a 1 inch bar is associates with 1 ribbon fault. So if the bar was 3 inches in from the left of the screen, the faulty ribbon will be 3 inches in from the right working from behind the TV. If cleaning dont cure the fault, then the Buffer IC will be blown and order a new centre buffer board (you can buy off Ebay)
