FYI - the CRT bias control is fed with +200V which feeds through a 220K resistor, then the pot, and finally through a 39K resistor to ground. I'd check the wiper of the bias pot for a varying +30 to +100V. If no voltage, then the bias pot and two resistors should be checked. If this is good, check the 3.9K resistor that feeds from the crt bias pot to the CRT G1.
Hope this helps,
