That screenshot may have come from me. I don't have the CLIP handy right now but it's the same one Shahriar used in his videos. (PLL Unlock) I fixed 2 440x units that had the same fault as in the videos from Shahriar. I verified the problem by following his instructions. (you need a working SA to do this)

I'd have to check my CLIP to see if the is a U54 or not. I came across another SA (4407) with this issue but it was a newer board and did NOT have the div-by-4 counter. :-(
