4.1.10 Exchange YBU, YBL and YM board - 50” HD w1

Unplug all of the FPC connectors of YBU (Y-Buffer upper)
and YBL (Y-Buffer lower). See “Photo 1”.

Unplug the connector CN5412 between YBU and YBL.

Loosen all the screws of YBU, YBL, and Y-Main.

Remove the board from the chassis.

Remove the YBL and YBU from Y-main.

Replace the defective board.

Re-assemble the YBU and YBL to the Y-Main.

Plug in connector CN5412 between YBU and YBL.

Arrange the board on the chassis and then screw to fix.

10. Connect the FPCs.
11. Supply the electric power to the module and then check the

waveform of the board.

12. Turn “off” the power after the waveform is adjusted.
