Gary;
I don't want credit...just makes common sense.
All Tech's that have serviced TV's are sure to know the difference.
If I put out a search for help, when I say vertical, I mean vertical. Have
been know to say vertical line, but then when someone tells me, in
directions, turn north or south, I would rather have turn left or right.
Farmers always give me those type of directions, on Service Calls, (turn
south on the 6th line)..hehe.
