All kidding aside we changed all modified cords as a CYA step. They
are redundant as everything is plastic. No effect on operating the TV.
BTW some chassii are hot either way......

As for doing a B&W first just get your set to be as good a B&W first
then worry about color.
Series string sets to find open filament do this.
Meter on AC, ground one lead. Go along pin 1 & 12 til you find one
with no AC on one pin.
BTW you will measure 120VAC all along the string. That will not match
the data. Its because with the open there is no current so no voltage
drop along the string.

I've done it both ways. Many times you can't get at the entire bottom of the chassis or PC board. The PortaColors are a classic example. I usually go for the higher voltage voltage tubes in the string, but that isn't always true.
BTW, those PortaColors sure are nasty to totally disassemble to replace the CRT.

Areas covered with plastic, especially GE's, were why dikes were invented !
Also found damper most likely followed by a tuner tube. For the tuner
part of string find the brown wire ( most sets ).
Never did a jug on a PC. Only ones changed were under warranty.
GE had a way of "pouring" parts into a set without a care in the world
that someone would have to fix it some day. When the started building
some great stuff they were soon gone.........
