Attached is the waveform from the schematic. It shows 1.4V. Thing is, with the IF module in place, there is just over 6V on the test point and 4V with module removed. Not sure where to go from here as setting it up with the 75ohm resistor and a 75uf cap (negative towards signal side since its voltage is less than the connecting point on the chassis) gave me a very dark image with bad sync.
Also, tried the "new" IF module and it is either not new, or not aligned. When I installed it, the color went full and the color control wasn't functional, or it was but had no affect.
