Not Outputting Video From RCA Composite Jack

Hey guys,

Having a bit of trouble with a Nintendo Entertainment System not sending a signal from the red and yellow composite ports. So far I have refurbished the refurbished 72 pin connector and I’m getting a great solid red light when the system is on. I also disabled the lockout chip to avoid issues there.

I’ve tested the system on two modern TV’s. One 1080p and on 4K in the composite ports. I have played other “retro“ systems in these ports in the past.

I just ordered an RF box to test if there is a signal coming from that port, but it’s a week out.

Answer this question I have this problem too

Is this a good question?

Any update on this with the new RF box?
