What to do about vertical lines ... already changed out t-con board

Hey I have replaced t-con board and ribbon, and still have coloured, vertical lines appearing on screen. What should I check next?

Also, any tests for that particular t-con board to verify it is not defective - tv model number is LN46A530P1FXZC.

Any help is much appreciated!

B P that will depend on what those lines look like. Post an image of what your screen displays with your question. Use this guide Adding images to an existing question for that. Besides the T-con board you can get lines from a bad main board as well as TAB failure. Tab failure is where the bonding of the ribbon cables from the driver board to the inside of the panel have failed.

check the ribbons that go from the tcon to the lcd panel itself, to do that you will probably need to take the bezel off and rub you finger along the ribbons
