RCA Color missing

Hi Group, I am working on a RCA TV #F32645, CTC203CH3 it was a dead set, I replaced the flyback, hot, and the vert. output u14501, the set came alive, ok, now the color is missing, it is in basicly black & white, there is some color, but it is very very very very faint, i checked all the resistors, they seem to be fine, when I use the menu controls they don't do anything, the screens are in color, but other than that, I'm clueless @ this point, any help in this matter will be taken seriously, and you will be rewarded with my sincere gratitude, Thanx, Stan...

This is in general: You will need the service manual, and a scope. Check to see if you have the burst oscillator working in the colour demodulator section.

The most simple check you can do is determine if there is proper voltages to the colour demodulator section.

One thing that may have also happened is that there may be a missing voltage from the secondary supply side of the flyback output side. If you look in the schematic of most TV sets, the flyback output goes to some high speed diods and then to some filter caps. This is to supply secondary power to specific sections of the TV set.
