Have a 27K7500 from a Gauntlet Legends, image looks good but there is no color. Contrast control has no effect. I have checked the contrast pot and that is fine.

Suggestions?
 
We have a winner

Or as they use to say in the olden days: "WITCH!!!" :)

75K 1/2 Watt resistor was open. Of course I didn't have any of that size on hand so faked it short term with a 56K + 15K (which got me about 70K). Got color back, and some contrast control. Not perfect but enough to show me it is on the right track.

Tomorrow I will cap kit it and see if anyone local has a 75K 1/2 watt resistor on hand. If not I will add on another 5K and see if that gets me better response.

I owe you one Ken,
Thanks
