Nigel, thanks for the info. I too have never seen both resistor open Beyond 2M when color bands indicate 120K 2% (tested out of circit), and frankly it's been 10 years since I have even worked on a TV. Yes I did twiddle. But the set had zero volts at the blue drive pot. R and G had about 5V. Once I changed out the resistors, Boom, blue now present. Now that you said the replacements need to be exact, I'll change them out to the exact as I did not have, and used "close to". And yes I checked the color drive transistors (both OK). I have run the set for 24 hours now, still working.
