Schematic PDF for the TV model TH32A410H carrying the -3 suffix, 6.62 MB in size, the same size as the -1, -2 and -4 copies in this set. Identical sizes suggest these may be duplicates of one document rather than separate parts, so compare page content before assuming anything is missing. Open it with any PDF reader to follow supply rails, backlight and mainboard circuits, and verify the model label and board numbers on your set first.
