Red line on TV screen.

Have you checked the fuse?

try to disconnect all external devices connected to your LCD TV then try to turn it on again then wait for a minute. if the problem persist you need to get it serviced by Dynex.
hope that helps.

HI,
i think ur component video connection may inter changed. check it. are u connected red to red, green to green an blue to blue. if interchanged the picture will be black and white. also check the video system of ur tv and dvd.
about audio. for that u need a stereo rca chord. connect the audio output of ur dvd to the component audio input of ur tv. if u have already connected the audio cable , check the audio setup of ur dvd. there is selection for pcm audio select it and then check again.
ok

connect the AV cord into LINE INPUT of the TV (yellow> VIDEO, Red & White>LEFT & RIGHT Audio)
Then select which line do you connected., Line1 or Line2

If your TV is still under guarantee then change it asap, if not you have a problem, the panel has failed, in very rare cases the lines will disappear when the set is at its maximum operating temperature, that said it will never be 100% again, sorry

that is probly the closed captio is on get to your menu and turned off..
hope that help

Be sure to remove the dvd from the drive when you want to watch tv.

The unit will have to be serviced, this is a problem on one of the boards

Unfortunately you are right it is the display panel going bad. You can either live with it or buy you a new tv as the panels usually cost as much or more than the tv. Sorry.

If you push menu on tv and red line goes through menu as well you will need to change the lcd panel, I hope you have warranty or extended warranty
