I have a Sanyo DP55D44 tv and half the screen lights up. Took the tv apart and checked the backlights to see if they were good and all of them function with test with a backlight tester. I saw another post saying it was the led driver board. It showed the part that was replaced and fixed it. Question is, is it wise to take a similar part off another board that was functional and swap or just to order a new one. The main thing is would it be compatible i guess. The last picture is a scrap board from another tv that has the similar part.
