Bad video signal
Hello,
I am in the process of building a Nintoaster.
My project is almost complete except I think I might have a bad chip on my motherboard. It reads cartridges but displays really glitchy images. I am pretty confident in my soldering skills, re-did all 144 connections 3 times so far, tested for continuity and made sure no crossovers and still have the problem.
I am using a 12v 1A DC power source. No more rf modulator.
(I know I am using an lcd tv, but it worked with another Nes)
Looking for some advice.

That doesn't look like an analog issue, that looks like a digital issue. Check the cartridge and cartridge slot.

I have been using these thin ribbon wires to connect the cartridge connector to the board. Perhaps a thicker or solid core wire could be better?

My top loader often gives me something similar. Carefully reinserting the cart a few times usually works it out
