Any idea, anyone, pretty please?

My first thought would be the cart does not have a good connection.

Have you tried all the tricks you would have used back in the old days.   Cleaning the cart, angling the cart back and forth, I know you shouldnt blow on the cart, but sometimes that works, etc..


My second thought would be that the cart is a different region.   But...  If it is the same game and same system as when you put it away, this probably is not likely.


If the LED is not flashing, these are probably invalid guesses.

I tried looking around to see if others have encountered this problem.

Most of the posts I've read think that the cart might be dirty.  Using a Q-tip and/or a narrow eraser might help to get those cartridge contacts clean enough to see if this is the case.

Another post mentioned the lockout chip.  I don't think the chip would have gone bad, and if it was bad  I think the system would trigger resets over and over, so I probably would not disable it.  (since it involves NES surgery)

I have personally enountered a situation (once) where the RF box (inside the NES)  was bad.  I had a TV, cable and cart I knew worked, and that particular NES would not work using the RF connection.   However my RCA cables did work.   I do not know how you would verify this. 

Last thought is just an incompatibility with the TV.  If you can get access to another TV (preferably an older tube-TV) you might be able to verify this.   I do not personally think this is the case, but its worth a shot.

Sorry I can't be more help.    In my experience I can usually get a NES operational with a lot of cart jiggling. 

On the flip-side,  I often have horrible luck trying to get SNES or N64 systems to work.

I FINALLY TRIED AGAIN AND FIXED IT. ALL I HAD TO DO WAS CLEAN THE GAME CARTRIDGE WITH SOME ALCOHOL, DRY IT AND INSERT IT INTO NES. AND NOW IT ALL WORKS FLAWLESSLY! I HOPE THIS CAN HELP SOMEONE WHO HAS A PROBLEM LIKE I HAD.

THANK YOU ALL FOR YOUR HELP, BYE-BYE!
