Colecovision with power supply - experiencing video artifacts

[jeremysart]

I listed my Colecovision for sale on eBay, as it has been experiencing video artifacts/ glitching for some time. It powers up, and games are partially displayed, but as a garbled mess. Not sure what the problem is, could be something simple like a capacitor, but I don't know enough about electronics to diagnose or fix the issue, so I am selling the unit at just the value of the power supply.

This is not a huge loss for me, as I have a Coleco ADAM and another working CV unit.

Same thing, twice the price, different seller? Although this one has a box and three games. May just be coincidence with old CVs.
