G3260 Can't print yellow. Did two cleanings and a deep clean.

Hi there! 

G3260: Nozzle check is not showing yellow. Tank is half full. Cyan wasn't showing, but is now after two cleanings. I performed the deep cleaning too, and still no yellow. What should I try next? Flush?

Since the deep cleanings didn't resolve the problem you have nothing to lose by trying one of the YouTube cleaning methods.
