AV modded Famicom no picture... Broken??

[Bad Idea]

I got free one AV modded Famicom, but when I turn the power on it doesn't give picture. But it does give strange buzzing noise...

As you can see the AV cable is hardwired:



And inside it looks this:




So... Is the mod probably made wrongly or could my Famicom just simply be broken?

The buzz is usually for controller 2 mic,also did you try and hook it up with rf.

I don't have rf switch.

buy the RF switch online, from what I have seen they are really cheap

I tested my Famicom one more time and now it did give picture, but 5 seconds later picture suddenly vanished and it started making again that annoying  buzz sound.

oh
i recognized the few actual reasons of hot glued things:
1) improper wire's insulation removal. Some of copper cores damaged ugly and broken. Forgotten wire tinning.
2) bad soldering with a lot of oxidation at joints
3) very very nasty topology and component's layout design

so that non-hot glued OLOLO MOD breaks down even if you'll just breathe out on it
