My screen has a line on rt. Side its a color line from top to bott.

This is a tcon board or lcd issue.

The whole screen or what is called the panel will need to be replaced. the panel comes with all the circuit boards less the power board and main board.

This problems ur tv have can't not be fix by adjustment.The tv have a problems known as convergence problems,it dead.Tv have colors lines R,G,B mis alignments,have colors shadow pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts on the tv convergence board,must be replaced to repair the tv convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

the ysus board is the problem .this is the board on the left .check the conecting ribons first.normaly its the one that conected to digital board .

If still under warranty, I would suggest going that way as this is a bad matrix driver....

left or rt side

My LG RT-42PX11 after a few minutes the screen starts to flicker and colors go psychedelic and after some time no picture at all

your screen got dead pixels you can do this but this is not a perment solution

rub the screen gently at the end of the line (both sides that is top and bottom) the line will disapper but it may come in near future

Hi,
Is the 3 colored lines always in the same location? Top to Bottom or Side to Side?
The plasma panel is bad if it is from Top to bottom and the 3 colored lines are always in the same location.

The Z Sus, Y Sus and Y buffers are suspect is the lines are not always in one location and it is from side to side.

Repair cost is about half of your purchase price if the plasma is bad. I hope your unit is under warranty. Best Regards
