Samsung SM-T677 schematic collection in a 9.45 MB ZIP; this model code belongs to the Galaxy View 18.4-inch tablet with LTE. Samsung service schematics usually split the board into PMIC, charger, processor, memory, RF and connector pages, with net names that make cross-referencing easy. Technicians use them to follow charging and backlight power paths, find fuses and test points, and narrow down a short on a main rail. Unpack and open with a PDF reader. Check the PCB revision silkscreen against the drawings before replacing parts.
