RAR archive of roughly 18.4 MB related to AOC LC32D1320 and LC42D1320 LCD televisions, the 32 and 42 inch models of the same line. The name does not list the contents, but material grouped this way usually covers service documentation for both sizes sharing a common design. Extract it with WinRAR or 7-Zip and review what is inside before use. When matching any diagram or firmware to a set, compare the main board and power supply labels on the actual TV with those referenced in the documents.
