Take Apart Power/Analog/Video Board - 96
LG CRT
Identify an LG CRT by the
black plastic molding located
on the CRT neck. The LG
molding has the LG name at
the top and three holes.
If the iMac uses the 661-
2465 power/analog board
(with the switch) and the
tube is an LG CRT, make sure
the switch is set to LG.
