I have a grey line on the far left of the screen my left as I am looking at the screen of my Panasonic Viera TH49EX600. It is about 2 inches wide. It covers the content underneath.

The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

If you let me know in which location of the screen is located I can assist with the possible cause since the vertical line can be caused by different items based on where its located on the Screen such as center of screen, or far right side or midle of the right half side of the screen. Reply to this same post with where the line is located and I will assist you with it.

the problem is the panel is going bad. usually not economical to repair. repair usually runs as much as a new one.

Either LCD transistor got moist or the video chipset got condensation. Keep TV on standby to dry it out. Unless there is also mechanical damage to the lcd screen on the edge..

Need to know if the bar is cutting off picture or if the picture is being squeezed to fit the remaining space

Back light inverters need to be replace.

It is either the plasma panel itself or a connection problem, either way it will need to get serviced. Suggest you find receipt and phone Panasonic.
Cheers.

Thanks...

I would suggest to exchange if you've noticed those lines. Do not wait for too long.
Good Luck
