Famicom modded, black screen

[zinho]

This is a AV modded Famicom that has a hum. Video shows black, did have some sfx when I tried before, somehow I feel like it’s a simple fix

How come your account is older than mine, zinho?

Post pictures of the console otherwise no one can help you

Probably something simple like the video is sorting to ground or shorting with another signal, like the audio.

You'd have to visually inspect the video and audio wires from the PPU, through the transistor mod, to the eventual output connectors. Pictures for us of those things would help with diagnosis.

Thank you all,
Sorry but I’ll wait for a new set of cables. Will attempt to report after
