I'd check all resistors and caps around V209B, including the brightness control. You do need to have the correct DC bias voltages on the CRT first. Then provided your horizontal and vertical circuits are working, you should see some sort of a raster. You did mention you have 12K of HV, so apparently you have horz drive and your flyback is working...
