Schematic PDF, 1.14 MB, named t43_2. The trailing 2 may indicate a second part of a split document or a second version, which the name does not clarify. No brand, board number or revision is stated, so read the title block to confirm what it covers. If it is one part of a set, other pages may be in a companion file. Use it to trace power rails, check signals between chips and identify components during board-level repair.
