Interesting. To be honest I wouldn't know where to start but if you manage to get a replacement flyback, I'd be interested in hearing if you have the same issue

The one that gave me a ton of blooming was a HR 7533, the one used in the 1084S-P1. I think the HR 7506 wasn't as bad, but did cause that ringing issue on the left of the screen

Nice. The ol' dead test is more of a curiosity these days. Like let's see what dead test says, oh black screen what a surprise

I thought we all moved on to using touch screens

You could always steal them off another Famicom for a test. Or swap the two on the board around and see if it changes behaviour

Nice resto! I'm not super familiar with the twin Famicom but I'd would suspect one of the 40H368's. Looks like they're labelled IC101 and IC102. They handle buffering & inverting the inputs from the controllers and exp port. A bad one could explain what you're seeing (sort of). 74HC368 is equivalent

And just for fun I added a little colour to the tuner LEDs.

The originals are a size that seem impossible to find so I had to improvise a little. Also used a little 240 grit to rough them up and diffuse them a little. Once again the camera makes them look a lot brighter than IRL.

I ♥️ this thing
