I have a GO5-802(Asteroids 19"), the monitor died, so checking things out, found fuse F700 blown, and resistors R705,708,714,and 718 fried and Q706 bad on deflection PCB(issue 2 version). Found 1 bad "bottle cap" transistor bad on side frame. I replaced all Items listed above, and also replaced Q707. Also should note a cap kit was installed along with new "bottle cap" transistors a short time ago. After replacing all parts, reinstalled, and right away R705, R708,R714, and R718 went up in flames! Any ideas what I missed, or could be a problem??
Thanks for any help

Replace the burned resistors again, check the transistors again and this time replace your ZENER diodes @ ZD 100 and 101.
 
Thanks for the reply, could you help point me to where ZD 100/ZD101 are on the deflection board? I am unable to find them(or there value) in the manual, or on the PCB.
Thanks for any info
Aaron
