VECTOR: black widow xy monitor problem

  I have been trying to get this monitor up and running. But still have 
a problem with the picture only showing a dot in the middle of the 
screen. If I turn up the brightness on the HV, the dot gets bigger. I 
can here some chatter. There is an lv2000 installed. Checked all 
transistors on chassis , checked out good. Checked HV board replaced 
1.5k resistor that was burnt but it didnt fix the problem. After 
resistor was replaced I forgot to plug in ground on HV board from 
brightness& focus part of the HV transformer. It made aloud squelling 
noise. It then stopped when I plugged it in. I saw some smoke but 
couldnt see anything burnt. Could I have hurt something else?
Any ideas,
