Nintendo 64 Troubleshooting
Nintendo 64 Game Screen Not Displaying Properly ¶
The power light is on but the television screen is black, flashing or does not look right when turned on
It's Dirty ¶
Most Nintendo 64 problems can be solved by cleaning the game cartridge or by cleaning the cartridge slot.
Reseat the Jumper or RAM pack ¶
The Nintendo 64 won't boot all the way without a Jumper or RAM pack properly installed. Open the little cover on top of the console, pull the expansion pack out a bit and then pop it back in.
Problem with RF or AV Cables ¶
If cleaning the system does not fix the problem there may be an issue with the RF or AV cable hookup to your television. Verify that the cables are hooked up properly. Also verify your television's compatibility with the type of cables you are using. If this yields no answers, swap the cables with another working set of cables to see if this fixes the problem.
Nintendo 64 Won't Turn On ¶
Turning the power on yields no results
Problem with Power Cord ¶
A bad power cord could be the cause of your Nintendo 64 not turning on. Verify it is hooked up properly, then swap the cord with another working power cord to see if it fixes the problem.
Bad Motherboard ¶
If your console does not respond in any way when the power is switched on it may need a new motherboard. Most of the unit's parts are attached to the motherboard, so replacing should provide a good all around fix.
None of the Above ¶
If none of the above remedies the problem with your Nintendo 64 your best bet is to replace the unit. Fortunately, it is an out-of-date video game console and thus available for a very reasonable price.
