I've got an Emerson PC6 5 inch color TV that i am trying to bypass the tuner on. Found the video out from the tuner IC:7530AN (Pin 16), but when i cut the trace and feed my video signal into Transistor Q101, i get either no picture or a black and white picture, depending on if i send it direct to the transistor or through the filter connected to the transistors base.
I have attatched a schematic from the service manual, is there an easy way to inject video with color?
Could it have anything to do with the video signal being at 4.4V from the tuner?
Here's a bigger version of the service manual.
