So, first off.. it's a PAL Coleco. I don't know too much about those.
You can test the VDP, but odds are your getting a signal. (Based on you screen shot.)
Is the a tuneable slug/inductor in the modulator? For channel freq.
The part you have circled is an old shcool inductor.

It's a PAL version. nanochess, so i can connect a composite jack to pin36 (center) and the ground of VDP, external side of the jack (pin 1 may be, i need to search schematic of VDP).

Anyone know the specifications of that old inductor encircled? I want to change it.
