Couple things.
1 Are you actually using a power supply and not just the horrible battery pack the thing comes with?
2. Check the ratings of the power supply you're using. IIRC, the stock one for the PowerJoy is something insane like 7v 350mA. A real Famicom (and thus Famiclones based on it) use 9v and 800mA. I have discovered with my Powerjoy power supply wasn't enough to run some Famicom games because there just isn't enough amperage in the stock design. Try using a power supply from a real Famicom or model 1 Sega Genesis. (NOT nes)
3. The NOAC might be failing. If so, there's nothing you can do about that.
4. If all else fails, open it up and take a look for anything that might be problematic.
Also, I love that the related video is my Supaboy review lol
