Swapped out the board in my TV after it was having black vertical lines on all inputs and all menus. Installed the new board with no issues and now it won't fire up. It tries 3 times and than all 3 LEDs flash as if I should replace the bulb but with the back cover off I can clearly see the bulb shining brightly with a purple-ish hue just like it did before I replaced the board. I ensured all my connections were seated properly and prior to this the lamp had no issues. Any ideas?
