I have a 46 inch , Sony XBR 4 tv . The past week there has colored vertical lines that appear on the screen for about 10 minutes . Then they go away . What is the problem and solution?

LCD correct?

There are 2 types of lines they may be showing, both requiring the replacement of the LCD Panel.

1. Delamination Lines- they are usually multiple vertical lines that do NOT flow from the top to bottom of the screen. Looks look water dripped down or something similar

2. Single/Multiple Vertical lines - This is normally 1 or maybe a few solid vertical lines that travel from Top to bottom. I belive in some cases they may only travel to the screen center.

In both cases, this will always show when the TV is ON. Even if there is no signal being input to the TV. There are other possibilities but these can be the most common. Both require a new panel.

this is probly the lcd control module unfortunatley it comes with a new lcd panel
change these.

if the line is in the same place all the time im afraid to say that is a pixel problem on your display contact sony they may offer you a replacement display or altleast a way of changing the set.

If it still under warranty, no cost will be there, but if its out of warranty, you have to pay to Sony (might be they give you some discount) because its problem in LCD Panel.

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad

This maybe the symptom of a bad Panel. One Vertically This line is 99% bad panel. Call your warranty provider or SONY tech support if purchased under 2 years.
