After installing a new fly & HOT,this unit is blowing the Q410=K1917 at turn 
on.The HV is way too hi,31kv.I see this for a second before the fet blows.The 
Collector of HOT,Q407=BU4522AX,is 63vdc.
Tks to William Braell for telling me this is probably a Viewsonic,made by Jean 
Co.He also sent some pdf's & gif's but they are[through no fault of his] almost 
impossible to read.
There is also a single ''green wire'' that goes to M403 on the mains & I can't 
figure out where it plugs in,if anywhere.On the M403 pad of the mains  are the 
following components ;
C424,C425.There is 63vdc on this wire.This is not the loop wire that clips to 
the top of yoke assy.
Any assistance on the above is appreciated.
BTY-I do get a good pix for the brief seconds before the fet caves in,even with 
the HV at 30kv...........TIA.....
