Default There are 2 black lines on my LCD TV

When i turn off my cable box and leave the tv on, I notice 2 black lines on each side of the screen that run up and down.. They go away when i turn the box on and the picture comes on.. Is this normal

When you are watching TV, do you watch content that has black bars on the sides, or content that fills up the whole screen?

If you're watching stuff that does have the black bars, you're probably just experiencing image retention, which is normal, and never permanent on an LCD.

Yes they can in fact become permanent over long periods of time. That is why many manufacturers say limit your 4:3 aspect (pillarbox) viewing to 40% (I believe) of the time.

Interesting. I didn't think the technology allowed it to be possible on an LCD.

Btw - I dig the new avatar.

Well you would be wrong. But it is very rare on LCD displays.

Notwithstanding the well documented difference between "burn in" and "image retention".

I am not aware of the potential for permanent "burn in" on LCD panels.

they only show up when i have the monitor on and the cable box off. They are very thin lines that are on the left and righe side of the screen. When i change the screen size, Thet disappear

Ive come to the conclusion that it is the cable box that is causing the issue. Its the way it sizes its formats. When i switch to DVD on a different source, The lines are not there.
