Well, the schematic does show 2v at the cathode so I'd expect the first grid to sit somewhere around 0 or something negative. If the cathode is low, I'd suspect the cathode resistor and bypass cap. If the grid is high, look at that integrator or the 15k resistor next to it. Also check the voltage at the sync clipper plate and the resistors connecting it to the vert tube.
