How can you tell a bad LCD panel?

My TV started having yellow vertical lines through the entire screen. Sometimes it looks like you are viewing TV through a window screen.

It sounds that it might be a panel problem. But, before make it sure, it will be best to contact any service technician. If you wish to get more details about defective LDC panel problems, check the site linked here. It has screen-shots to that. http://electronicshelponline.blogspot.com/ Pull up previous posts there, either by type in the model name to your set in its search box, or view it in Timeslide / Mosaic option.

SOURCE: 40 inch lcd blue line vertical

The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

SOURCE: Thin Yellow Vertical Line - Samsung LNT4665F LCD TV

Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

SOURCE: CRACK LCD TV SCREEN

I had one broken a few months ago. I got a couple quotes.. it was about $200 less then a brand new one. I'd just buy a new one.
For the new TV I'd pickup a screen protector for it. My son threw a toy at my TV the other day and I nearly had a heart attack from the flashbacks. Thank God I picked up one of these a few weeks earlier. It stopped it. LCD screens really break easily as you know. http://www.tv-armor.com

It sounds that a loose contact to its flat wire connection that goes to panel from T'Con board. Re-seat it once and check. If you wish to get more, check this link.

You can either use test equipment etc or start guessing----most likely board would be main board that controls screen and all information viewed there.
