On second thought this looks like a HV failure. First measure all voltage rails, make sure they're all fine.
Measure voltage across C34 as well. Should be around +100v.
Measure across R49. Should be 115v.
Measure at pin 2 of J3, the voltage should vary between -15 and +100v depending on the setting of the astigmatism adjustment.
Measure J11. Warning HV here. Report back.
