When I put a game in my NES there are wavy lines moving down the screen. They disappear after like 5 min of playing but it's really annoying. Any way I can fix this?

Well the reson why there are lines in it becuase its starting to wear out the connections or if you are using the av cables or an rf switch it might need a new av cable or and rf switch then.

The NES is touchy like that, sadly-- your problem isn't uncommon. My NES, and the NES of nearly every friend I have who still owns one, plays this little trick on them from time to time. Here's what we do:

1. Turn off the NES console.
2. Blow into bottom of the game, near the chip that connects to the NES.
3. Wipe away any excess dust from the game itself.
4. Blow into the console of the NES.
5. Wipe away any excess dust.
6. Re-insert the game and try again.

If this doesn't work, try placing the game in more delicately, or with more force. It's just a matter of trial and error, and sometimes it will work faster than others. Hope this helped!

Well it is caused by a broken or a loose connection the so try buying a new rf switch or av cables to see if it works if not then the bad news is that the super NES console is on its way out then. 5
5 STARS IF THIS WORKS.
Or try cleaning the gamepacks out too with qutips and rubbing alcohal.

This is a result of faulty or dying dip I.C.'s on the TV's Logic Board. There are several that span the width of the TV, when one goes faulty it results in a vertical line.. often yellow. The Logic Board is most likely small, containing at least one big chip wich is the micro... Contact you TV manufacturer and try to get a replacement.

Good luck.

Well I think that the rf switch is causing this problem so use the NES av cable to see if it makes a difference then.

Well it might be the carrtiage bay thats broken and it will need a new carrtiage holder then.

thats cause your connector is going bad probably. to verify this, instead of using the RF connector, use the a/v cables and if you get white lines either way then you know the connector inside of the NES needs to be changed.

a 'front load' nes ALWAYS does this, even if the connector pins inside the console are new. the cartriges on a Front Load nes rarely completely seat, as Nintendo redesigned the Famicom very poorly for the US market. try this 1. put the cart in as usual, but hold it all the way down 2. slip an unwanted/extra cart in on top of the metal hoop above the cart your using. this gives a better contact for the cart. try cleaning the cartrige pins as well. some won't read right if there's ANYTHING on the pins.

first off flip your nes upside down and remove the screws to the cover of nes..... then flip your nintendo over and remove the cover.... remember you just voided your warranty for your nes..... then proceed to do the following:

find Chip 3193A and find the 4th pin on the left hand side near the blue coils. Remove or pull back the pin and your NES Will play Pal and NTCS games.

If it's just your power light that doesn't work but the system still t powers on it should be fine. You just have a broken bulb.
