Hi @dtroscla ,
Here’s a link to the panel self test procedure for the TV taken from the service manual.
You first need to check which LCD panel you have. Check on the back of the panel for the maker’s name.
If you have a Samsung panel this will help to determine if the problem is in the panel itself or in the signal board.
If you have a Panasonic panel, here’s an image of the troubleshooting flowchart which shows what to check.
Use the flowchart as well if you have a Samsung panel and the panel tests OK.

Hopefully this is of some help.

This is fairly common on LCD and plasma screens. It can be caused by a number of different things; the most common is the connection to the edge of the LCD. If you search YouTube you can find videos that show how to fix. It’s fiddly to get the TV apart, you’ll need plenty of room, and discipline in labelling the screws so that you can put them all back in to the same places.
Be very careful when repairing; you’ll have to run the TV out of its case with exposed connections. I can’t remember if your model uses a cold-cathode high voltage backlight or not; if it does there could be 1000V or more exposed at the edge of the screen.
