I have problem with a disk system (actually  two, maybe it's the same problem).

The little screw that supposed to be seal with red stuff, it is a bit loose so it can be turned. So since nothing else seems wrong, I have turned it a bit, but it hasn't helped and I'm not sure what to do next.

How sensitive is that reading head? If it has been moved a bit once, it is possible for a person like me without a micrometer to set it straight?

Edit: I seemed to have fixed it a little, turns out that I had placed the reading head in the exact opposite position that it should have been, and now it works (some of the times). So I suppose the position of little red screw isn't hyper sensite.

This is the board of my av modded famicom
For some reason, the video is all screwed up: wrong colors, distorted picture or like occupying the upper half of the screen, appearing cut off.

US NES or SNES controllers have pretty long cables with the right amount of wires and a very similar look & feel. You could get a pair of trashed controllers for cheap to cannibalize their cables.

You can also buy multi-core cable at an electronics store, but most of the time it won't  the right color or thickness to match video game controller cables. YMMV.

Hi guys,

Extended the controller wires but when i put everything back to test them i think i might have shorted an ic, the ground wire from the av mod most have come lose and when i had a look the ground wire was connecting two pins of the 74ls373  Cry

All ic's are getting 5v, could this have shorted the chip as there is no video or sound and i've replaced the transistor, resistors and cap  Sad

Does anyone have a basic list of troubleshooting steps for the original famicom?

I've got an FC that displays a different colored screen depending on the cart I throw in.  Sometimes I get  random display of letters on the side of the screen, matrix style!

Any thoughts here greatly appreciated.

Well, I think it is broken.  Undecided

You could try opening it and give everything a good rub with alcohol or some other cleaning fluid for electronics.

I think it's dirty, check both your cart and the pin slot.

Hi Guys,

Having a problem with hyper sports and hyper olympic on my scopian 8, i can select player but controls don't work on ether game, it just seems to be these games, is there any known problems with these games on clones?

Cheers

i'm pretty sure the Famicom versions of Hyper Sports and Hyper Olympic both need the special Konami controller. your best bet is probably to find a pirate cart, the US Track & Field (which combines both games and doesn't need the controller) is really really common on multicarts. I'd imagine even pirates of the Japanese versions would be hacked to use standard controllers.
