Subject PINCHED WIRE HARNESS (LB)
Model LC-42DH77E/S/RU
General There were cases that the LB-wire harness (QCNW-H853WJQZ) was pinched between the rib of the
cabinet-B and the VESA angles.
If the LB-wire harness was damaged, the unit may exhibit some phenomena below.
･ Inverter shuts down (indicator shows error)
･ Screen failure (bright and dark horizontal stripes appears when brightness is low or high)
Servicing When the unit requires service due to the above mentioned defect, replace the pinched LB-wire harness
(QCNW-H853WJQZ) with new one, and make sure that the LB-wire harness is dressed correctly.
Also when the unit requires service for other defect, visually check if the LB-wire harness check is pinched
by viewing from the grids of the back cabinet of the unit at the same time.
If the LB-wire harness is not pinched, it is not necessary to replace it with new one.
