retrocat:
good info.
i'll pull the c36 and check if its ok. what should i do if its bad? replace it like this http://www.thegleek.com/bobroberts/csc.html and keep the one on the bottom as well?
Zebidee:
Brownie caps don't fail often like electro caps do. If it is bad you can replace with a single cap of the same type and same combined value (you'd need to read and interpret the cap codes, add the values, replace with cap of that total value or as close as possible - there should be a little wiggle room).

i got it!
replaced the voltage regulator, c37 and c38, all tested bad.
c36 and c69 tested ok so i left them alone.
now i have a new issue, i cant get the vertical position right. it doesnt want to take up the whole screen, and its getting squished at the bottom as well if i move it down too far.
Zebidee:
Well done!
Check pots (vertical of course). May as well check your B+, as you've changed that voltage regulator. Also check voltage to your vertical deflection IC. If it is wrong then you might have a failed or failing support components (resistors, caps) nearby.

and give the 50/60hz pot a little tweek
