DUO RX emits buzzing/humming sound from speakers

[dave_van_damn]

My Duo RX emits quite a lot of buzzing from the TV speakers when playing games. No audio skipping or anything like that - just a constant hum. It gets noticably worse when the screen fades to white or there's a white background on the screen.

Compared to my Breifcase set up, the hum is much louder. I figured it was a capacitor issue but I've searched the forums for info but people are saying that DUO-R/RX don't suffer from capacitor issues. Any ideas, gang?

Thanks again!


EDIT - Tried a bunch of different cables and eventually found one that doesn't have this effect, so I gues it was due to a cheap cable. Sorry!

is this system by chance RGB modified? With an RGB modified system this is a sign of a poor quality cable

No, it just uses the regular AV cable. I have 3 in total, 2 made the humming sound and the 3rd (which was of noticably better build quality) was fine. Although I've since noticed it's not outputting in stereo

its probably a genesis 1/master system cable if its only one channel coming out.

also what power supply are you using?  an original or a cheap aftermarket one?  you could try a genesis 2 or ps2 slim power supply if you are using a cheap one.  the power supply could be what is causing the issue.
