  • Description: LSU Motor does not work normally. / LSU Hsync signal is abnormal.
  • Remedy: 1) Check if the LSU harness on the main board is connected properly. 2) If it is OK, check that the LSU harness on LSU board is connected properly. 3) Check if the LSU harness is defective. 4) If the problem persists, replace the LSU. 5) If the problem persists after replacing LSU, replace the main board.
