Yes, that will be my first stop. The previous tests gave no evidence of the chroma oscillator working, and I just ran across this note in another part of the manual:
"If the 3.58 mc. subcarrier oscillator does not operate and provide adequate bias voltage to the grids of the G-Y and R-Y demodulators, a picture having an overall yellow-green cast will result." That just about describes that awful color-bar image.
I don't know if you can test a crystal with my feeble collection of instruments, but I have a handful of 3.58-mc crystals left over from previous adventures, so I can test by substitution if I have reason to suspect a bum crystal.
