NTSC NES - Humming noise

80s Synth Pop

Hi all,

I bought an NTSC NES off ebay but it gives an awful HUMMING noise from the television speakers plus flickering on bright screens.

I've read reports tht the PSU may be the cause...

Since the NES takes in 9VAC 1 amp, can I try using a standard PAL power supply on this instead of USA PSU and stepdown converter?

Cheers,
80s

Not to familiar with the insides of a NES but in most cases where you have hum like you describe it would normally point to a faulty capacitor. I am guessing that seeing as you have 9v ac going in that the capacitor is internal, as you need to change you ac to dc. The capacitor should be smoothing out the ac but as it goes bad it lets a bit through giving you ac hum.
Have a look at some of the Randy Fromm videos on you tube to have an understanding of how psu's work

Just in case someone else ever has this problem - it was indeed the power supply

It's a NTSC USA NES but a standard UK/Ireland power supply works fine. This is the one I picked up - http://warnersretrocorner.com/store/products/psu-for-super-nintendo-nes-more-consoles-2-5-mm-jack/

Let me say the NES never looked so good. Perfect image, perfect sound, 60Hz, no borders on a 50" screen with Captain Skyhawk

You could always ask Retr0 his opinion.


Oh, sorry, never mind.......

We could get an ad made,
"for just €5 a month you can help Retr0, this poor retro games player has suffered in relative silence, his plight not owning a Nes and therefore rendering his name Retr0gamer a lie.
You can help, your €5 will be put to good use, buying him a Nes and the training needed to use it into the future, providing much needed retrogaming kudos both for himself and his family.
So, please donate what you can and help, thank you for listening"

I was going to donate until I read this

Seen this recently, Retr0 is the new Burton. He really doesn't like 50Hz

So is the power supply ac or dc, from what you describe its dc and not the ac i thought.

Thought someone had hacked my account there! 60 Hz 4 life.
