I have been doing so voltage checks around the PLL and things aren't =
good.

U4
p1 2.1v=20
p2 2.4v
p3 0v
p4 2.3v
p5 0v --should be 5v
p6 5v
p7 5v --should be 0v
p8 .1v
p9 5v --should be 0v
p10 5v --should be 0v
p11 5v --should be 0v
p12 5v --should be 0v
p13 0v --should be 4v
p14 0v --should be 5v
p15 0v --should be 5v
p16 0v --should be 5v

U5
p1 5v --should be 0v
p2 0v --should be 5v
p3 ok
p4 ok
p5 5v --should be 0v
p6 4v --should be 2v
p7 ok
p8 0v --should be 5v

U6
All voltages ok

Q19
G 1.45 --should be 0v

Anyone have a suggestion where to look next?
