Can't get my old famicom work

[ouso1999]

Hi guys
I have an old famicom whose model is dy 656 but I lost its cables . I remember I used to use rf video cable to connect tv but that was when we used to have an old tv so how can I get it work on a smart tv now ?
and for the power I used to have a multivoltage adapter for it but I forgot how to adjust the right voltage for it and I can't remeber how to set the polarity too .
here are some pics of my stuff

RCA Audio Video to HDMI converter should work. The other part. I don't have a good answer.

hmmm, i know this is an older post, but i suggest you possibly look into your specific model, like if there is a manual online, or if there is any documentation...  thats all i can suggest as i dont own a famicom of my own...

yours is also a bootleg model, made clear from the "COMPUER GAME CONSOLE" sticker and the blanked out copyright information, so id be careful whe experimenting with voltages, it could just use a standard format for cables aswell, most bootlegs do, but it really just depends on what year your model came out in and stuff...

so take back what i said, idk if your gonna find a manual for this, probably never came with one in the first place,
heres what the bottom usually looks like (on a licensensed one)
