My NES console gives us a pink screen red blue black orange teal aqua green lime green light green purple then or black the.

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.

SOURCE: Wii Console will not turn off.

try turning it off on the console and not with the controller. turning it off with controller turns it yellow. press and hold the power button on console for 5 seconds it should turn red.

Well those 3 way adapters are bad news then use an offical NES ac adapter for ensured quality.

SOURCE: Does the original Nintendo NES-001 require a certain AC adapter. Cause I doesn't have the original ac adapter with same spec. My console power light is blinking on an doff. can that be the issuept

As long as it's 9 volt and about 500mA it should be ok. Just seen an original that says 9 volt and 400mA.

The current (mA) can be higher than the original but not the voltage that has to be 9.

1000mA = 1 Amp. So anything over 400mA is fine, but not less.

Testimonial: "so If my ac adapter is 12v dc 750ma which is not the same so can that cause powering up issues with the flashing red power light. Or is the system broken "
