Nanao 2934 geometry & convergence issues

Hi guys,
as you can see in the photos my Nanao 2934 has some convergence and geometry issues.
I'm not a technician, what can I do to try to solve them?
Thanks in advance for reply!

check a different power supply, vga cable for a start
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? :(

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.

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?

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 minute...
