This has been driving me nuts over the past weeks.

The problem: audio buzz (gets louder when there is a white screen and when volume is turned up)

Consoles affected: snes, neo geo aes, megadrive 2, ps1, saturn

When using a pvm 2130 with original ss-x6a speakers, there is this buzzing sound coming out of the speakers. I'm using RCA's coax rgb cables, which made the buzzing a lot less i/o using my old rgb cables, but it's still there. When I use my samsung lcd, the buzzing becomes almost a screetching which is very loud (nintendo switch is silent on this lcd).

Any ideas how to fix this? I'm using a stepdown convertor 230V - 50HZ, AC 110V - 100W (is this too heavy for consoles mentioned?)

What's your cabling setup like? is your console's SCART cable plugged directly into the monitor, or going through a switcher?

A good way to tackle this is to ALWAYS breakout the audio from the console's SCART cable, wether it's with a SCART audio breakout box, or a SyncStrike.
