PVM-20M4A green screen than goes into standby

Hi everyone, I'm a bit desperate and any help diagnosing/fixing this would be much appreciated.

I bought a PVM-20M4A on ebay and I received the monitor today. The packaging looked alright, I just noticed that the monitor was lying on one side in the box.

I have been unable to make it display anything though.
Here's a picture of my cable setup: https://www.dropbox.com/s/shhha0cc8r...35029.jpg?dl=0
The BNC cables are connected to a female SCART connector, to which I plugged my RGB video source (a Super Nintendo).

I also have shot 3 videos representing what happens with:
- no video input, just powering up the monitor:

- RGB video input, without the EXT. SYNC cable (you can hear the sound coming from SMW in the background):

- RGB video input, with the EXT. SYNC cable plugged in:


In all the above cases, the monitor seems to go into a sort of standby mode right after being powered on. It doesn't react to me pressing any button.
I cannot also access the sytem menu at any time.

Thank you
P.S.: I already contacted the seller with all the above info and I'm waiting for his reply.

 

I assume you have the input buttons set correctly as you mentioned no menu access (and s-video would give the same result, most likely). Dropbox pic doesn't seem to load, by the way.

It looks as though the protection circuit has detected a fault and kicked in as a result. Could be a faulty HVR, as that was quite a common fault in these. Sony don't make those any more. You'd need to get it fixed by a competent engineer... although they won't be able to get hold of the parts, anyway.

Ultimately, you're better off just getting a refund.
