no idea what going on?

I am trying to set up a 3d 1h detected exp in solid. working on 700 MHz spectrometer,with a 3.2 mm probe. normal zg on 13c, is good ( so sample is fine). the problem occurs that i have two cp( cross polarisation) transfers steps in my 3d exp, I am not able to get 1D 1H signal out of 3d exp.the exp with the cp works well on 600 MHz spectrometer though. is it a probe problem or a magnetic field inhomogeneity? any clue will be appreciated.
