It's possible that the T-Con board or the screen is damaged, but it's difficult to say without further testing. However, based on the symptoms you've described, it sounds more likely that the screen is damaged. Covering a pin on the ribbon cable from the T-Con board to the screen driver board is not a typical solution for this kind of issue, and the solarized colors you're seeing are indicative of a damaged screen.
If you have the necessary technical knowledge and equipment, you could try swapping the T-Con board and see if that fixes the issue. However, replacing the T-Con board is not guaranteed to solve the problem and may not be worth the cost and effort if the screen is indeed damaged.
In general, handling a flat-screen TV can be delicate and cause damage, especially if proper precautions are not taken. It's possible that you damaged the screen while replacing the backlight strips. To avoid further damage, it may be best to seek professional assistance if you're not confident in your ability to repair the TV.
