CHAPTER 6 – SERVICE
2. Next unplug the Chassis Neck PCB from Chassis Tube Neck of the CRT by pulling back on the Chassis Neck
PCB. You will need to slide the Chassis Neck PCB off to the side to clear the Chassis Tube Neck. The Fly-
back cable that connects to the CRT just above the Chassis Tube Neck will need to be disconnected next.
Be very careful as the Fly-back cable can hold 250volts even when powered OFF. Pinch the gray rubber
flange, and slightly push in to un-hook the metal prongs that hold the Fly-back cable to the CRT, shown by
the arrows in the picture below.
