ok i found the problem, there is a 20mmf cap off t-5 that was bad however the parts chassis i have has a different cap, colors are not the same but it works horizontal oscillator is right there now but i dont know what value this cap is because i am alittle short left to right on the horiz size so this cap must set the frequency and must be right to have the right size on the screen. next is the verticle, maybe another cap as i think there are 2 or 3 in that circuit, non stop rolling but i can put a resistor from ground to the .004 can and stop the rolling but temporary. that cap is at pin 2 of v12 and this cap sets the oscillator in motion and if it dont run i learned that it will take out the horizontal size pot very quickly. this capacitor that went bad is a dogbone type and im wondering if a ceramic disc 20 pf can be used in place of this 20 mmf .
