Recapped My Predicta Tandem, I don't know what to do

So I was playing with the adjustments a little more and the picture got slightly better then all the sudden went completely white. I started to play with the tuner and the TV showed no reaction. I swapped the tubes on the tuner, and even unplugged the rca lead it had no effect at all. So I slid back the boot on the plug for the tuner, I think I lost a cap somewhere because now I have no voltage on the white wire. Here is what I found. I wasn't able to check the black wire in the center but from the diagram it looks like it's just power for the dial lamp and that is nice and bright.
Orange 207vDc
White 0 volts ac and dc
Green 0 volts DC 98 Volts Ac
Red 0 volts DC 90Volts Ac
I thought they should all be DC voltages am I wrong?
