    I read some previous posts and tried to help myself before I posted my question and already checked the R1300's. I've gone over some of these things so many times I am getting to have them memorized : ) But here is what I have: R1300 (3.3) on both R1301-1 (3.3) R1301-2 (3.0) R1302-1 (3.3)...

    Ok, sorry about that. I have been seeing a sine wave, now I am seeing a square wave.

    I'm not too sure on how to calculate this correctly. But I got 3.25 divisions per cycle at 5ms. I don't see a 1kHz reference output.

    U1900 is good if I have 3.4 on pin 13 & pin 12 has a signal? I have both.

    Little bit of liquid was near clock, U1845 (changed), C1020 (short to ground or low resistance to ground? .007). Everything else is pretty clean.
