Does the neck glow on the tube? and have you checked the video input plug where it joins the chassis.
I used to have one of these cabs, really nice cab to play on.

Re: NeoGeo 29 black monitor with sound !!!
you need id the actual issue first, and a lot depends on the monitor make/model to where the issue may be
the easiest solution is to send the chassis for repair if it is indeed faulty or buy a refurb replacement

Re: NeoGeo 29 black monitor with sound !!!
maybe something is loose like the neck card or a connector- difficult to say without being there

That’s what mine was, and it looks the same in your pictures.
Do you have a volt meter? I imagine as Grant does something has come loose in transit, you need to check all the connections and any loose wires and defiantly the neck pcb board.

It's definitely a GMK-29. Funnily enough, I think I just fixed one of these yesterday. New HOT and caps seem to have done it.

Either something is loose or there is a fault with the monitor chassis. If there is a fault you will need to discharge the monitor, remove the chassis and send it for repair.

I had this issue with a bad PSU. After Grant recapped it, I got picture back.
