This U5000 rev E board started "flickering" every (3) to (7) seconds about a month ago. See video link below. Note, the video shows pole position, but this chassis came from operation thunderbolt . .same symptom with both boardsets.
I've recapped, reflowed, and swapped the flyback and have gotten the same results. I did not replace the filter cap in the ps section. B+ voltage is 118.8Vdc.
My question is if the flicker is an issue with vertical deflection, sync, or something else entirely.
TIA.
