Take Apart Replacing the CRT - 1 25
Identifying the CPT CRT
The CPT CRT can be
identified by the plastic
molding on the CRT neck. The
CPT CRT molding has two
holes in the molding.
If the iMac uses the 661-
2465 power/analog board
(with the switch) and the
tube is a CPT CRT, make
sure the switch is set to CPT.
