Default Phone jack woes? Any experts?

New jack has screws for red, green, black and yellow screws. Old
wiring is two reds, two greens, one black, one light blue, one white
connected to six different screws. Can I connect these to the new
jack?

You only need to connect those wires that were (hopefully, still are)
connected to the old jack's red-and-green lugs. Simply transfer those
wires to the red-and-green lugs of the new jack.

The color scheme you describe is partially familiar to me. It sounds as
though your '70s-era home is wired with three-pair wire. If true, there
are three pairs: Blue, Orange and Green. (Blue + White-Blue, Orange +
White-Orange and Green + White-Green)

In a common installation, only the Blue/White pair carries dial tone and
should be connected to the red/green lugs on the jack.

If it appears there are TWO of every color, that indicates that the
house was wired using the continuous loop scheme: The cable descends
from above into the box then back up into the attic on to the next
location and so on. Just connect or "splice through" all the extra
colors (like color to like color), connecting only the blue/white pair
to the red/green lugs on the jack.

Failing this, subscribe to your telco's Inside Wire Maintenance Plan for
a month then have them come and fix it for "free". Good luck.
