I was doing a led replacement for a UN40H6203AF and ordered replacement strips, but the middle strip didn’t match. These series of Samsung LED TV’s use 3 strips with 2 angled strips and a middle straight strip. Part number is LM41-00001V for the angled ones and LM41-00001W for the straight one. When I installed the straight strip, the holes didn’t match. I noticed there were 12 leds on the strip and I needed 13. Though the angled strips were the same part number, the straight strip was different.

For the 13 led straight strip, the part number is D3GE-400-SMB-R3
