famicom nes

[Curtisloew88]

Hey everyone.  I new to the famicom world.  Ive been working on American nes for a while now.  I just got a Famicom system off ebay.  Seems this system only wants to give me problems. I had to replace the voltage reglator and the Capacitor.  The system worked great for about a week.  I wanted to play it today and it is all fuzzy.(looks like nes when the pin is about wore out, without the blinking)  So i was just wondering if anyone could help me out.  Thanks a lot.
