ok the hv sweep set up did nothing so now i took voltaqes off the video output tube pin7 is to be 230 v but i only get 152 v pin 8 140 v but i get 133 v and pins 3-9 is supposed to be 5v but im getting -0v so i am really lost here and i did try another video out tube. i also check the 6fq7 horiz oscillator tube voltages, pin 1 is 20v right on, pin 2 -.1v i get -.238 v and pin 6 245v i get 248v.

What is pin one of the video out tube? Does adjusting the contrast change these numbers?
Are you using no signal? The brightness and contrast control will move those voltage a bit. Maybe C3 is shorted, leaky or in backwards? Maybe theres something up with C40 and the blanking isnt working right? or the resistors in that area.... Im sure you replaced C3 (250uf) just because its new doesnt mean its good.
