Help monitor Nanao MS-2932-S
Hello everyone,
I have an annoying interference problem with Nanao monitor of my Sega Naomi Universal Cab.
Immediately after switching on, white interferences appears, as you can see below.
If I disconnect and reconnect that cable on my hand, they sometimes disappear, but reappear after a few minutes.
When I disconnect the cable you can hear the sound of a switch in the background... what is it? (Degauss?)
What kind of problem is it? Is it solvable?
Thanks in advance for your help!

I have no idea what you are doing, why are you shorting a cable?
What does it look like when a video signal is applied?

It's the degauss switch.grantspain wrote: ↑April 11th, 2019, 10:12 pm I have no idea what you are doing, why are you shorting a cable?

When I turn on the pc inside of my Naomi cab, you see the game... but the interference remains in the background... maybe it's a mass problem?

Hi,
I found out that my monitor is a Nanao 2934-S.
I solved disconnecting CN901 cable on the board (DG IN), the interference has disappeared.
Could the monitor be damaged with this cable disconnected?

DG is degauss, it won't cause any issues being disconnected
