Popping and Smoke coming from Famicom, and just other Famicom related questions

[Weisite]

Hello again! I work for a local game store that sells retro games and game consoles!

Today's conundrum is a recently (as the time of this post) traded in Famicom and Famicom disk system! When I plugged in the console, after a few seconds *POP* white smoke coming from the back! This is my first time ever working on a Famicom and I'm wondering what things I should keep an eye out for when cleaning, testing, fixing, etc.

Now as for the white smoke coming from the back we believe it could be a power capacitor problem but if that isn't the case I would gladly like to know! If any of you have questions about the console or the store I work for I'll gladly answer any questions!

Most likely a blown capacitor. I've seen it happen with the AV Famicom model before. I'm not sure if the red and gold model is the same but on the AV there's a big blue capacitor right in the back that can go up in smoke.

That is a blown capacitor, no doubt about it. You can probably find replacements on ebay or aliexpress if you look hard enough.

Here is a list of components the Famicon uses, find the capacitor there.

Please do not buy replacement capacitors on ebay or aliexpress. Look for a reputable vendor in your region. Mouser is a good choice in the US.
