Thanks Don.
At one point I actually reseated U1 just to be sure so I think I'm good
there.
Checked out U5 as you suggested. Here is what I found:
Pin Spec Meas Pin Spec Meas
1 1.39 0 << 5 4.44 5.8 <<
2 1.39 0 << 6 5.57 5.7
3 0 0 7 4.96 5.2
4 4.44 5.8 << 8 5.62 5.8
So this sort of implies that U5 is shot as well, no?? Do these readings
suggest any thing else I should check into?? (These results also got me
looking downstream from pins 14 and 22 on U1 that also read abnormal.)
I am guessing I should request a new U5 too?
Any other insights??
Thanks for all the help. It is appreciated.
