Been troubleshooting this ColecoVision for a while, only outputs video if I have the channel switch in the wrong position and short certain points to ground. I think the LM1889N is bad, will find out in a week or so!

Looks like I was right, the LM1889N chip in the RF box was bad! Put a socket in, old chip in the socket gave same results as before, swapped in the new chip and it fired right up once I had the switch on the right channel! Now all I need to do is remove my troubleshooting rainbow bridge and put it back together without breaking anything.
