Extron Emotia GX Operating Instructions

[Beaps]

If I remove the r,g,b grounds but leave the sync connected 14 it looks the same as when I had all the grounds going to pin 14.

You want me to remove the sync one also?

[fagin]

Please.

[Beaps]

Hehe ok back in a tick

[Beaps]

Ok removed the sync ground, picture looks like a 80s black & white tv

[Beaps]

You don't think it's this do you, I am using a 3rd party VGA cable. It works mint on an LCD or plasma tho

[Fudoh]

I have seen this kind of dimm picture before on an Emotia unit. Was a failing one which needed recapping. This is why suggested to try composite video or s-video on a standard TV set first. Just to narrow down what's causing the problem.....

[fagin]

Fudoh - I've seen this as well (I've had the same problem) but it wasn't a faulty Extron issue. However, this can lead us on to another are of investigation.

Beaps,
Try this:

Leave the SYNC ground DISCONNECTED (along with the R, G & B grounds DISCONNECTED) and put a bridge wire from JAMMA edge connector PIN 1 to PIN 14 parts side.

Let me know what image you get and whether or not this image has been replicated before, and under what wiring configuration?

[Beaps]

It's not the extron as I have tried this setup on another unit, same outcome

Ok Fagin let me try that now, oh and thanks everyone for the input & help

[Beaps]

Ok no grounds connected from any BNC, wire added from pin 1 to 14, still the same no image 80s tv

[fagin]

What do you mean, no image? You mean a B&W image as you had with no grounds connected?

[Beaps]

Sorry no image as in just static on the screen

[fagin]

Mmm... that alludes to the fact you JAMMA ground is up the shitter, which isn't good, but not really relevant here.

OK.

Remove the bridge wire and re-connect your ground from the SYNC to PIN 14.

You have a PVM yes?

[Beaps]

Yer but I ain't got any BNC to BNC cables

You think I should try the ground at the other end if the finger board to pin 14 if you think it goosed?

Also what about trying

- sync ground to pin 14 & rgb grounds to pin 1
- all grounds to pin 14 & the bridge wire from pin 1 to 14 also

[fagin]

STOP!!!....... in the name of love!!!

I'm in the middle of trying to repair a power board in a Gamegear, so you'll have to bear with me.

Don't start swapping grounds about.... you do know what is used for what on your JAMMA don't you!?

Please do as I suggested in my previous post (Remove the bridge wire and re-connect your ground from the SYNC to PIN 14.). I'm satisfied you have a ground doing something from your Emotia.

I have plenty more ideas on what to try yet, but (as Fudoh suggested) now is the time to verify the Emotia works. The other units you've tested could also be goosed, so whilst it maybe highly inprobable, we need to verify this either way.

I'd rather us test your RGBs output channels ideally, but since you have no appropriate cables, can you try the svideo or video out to your PVM or whatever?

[Beaps]

Hehe ok I will put all the grounds back to pin 14 & try svideo

[fagin]

Hehe ok I will put all the grounds back to pin 14 & try svideo

NO!!!!!!

I said put the sync ground back not ALL the grounds back.

You're a nightmare dude.

[Beaps]

Oh ok I reconnected just the sync ground lol

Ok so I dug out the svideo cable & hooked it up to my pvm and..... same image as the cab with the BNC sync attached. I tried one of the other emotias I got at its the same image?

[fagin]

OK.

You've removed the BNC connections when testing the SVHS connection?

If you slip the PAL and NTSC flip switch at the front, what happens (whilst connection via svhs)?

[Beaps]

The info on the pvm screen says NTSC then pal, the screen stretches kinda

[fagin]

The colours still all messed up?

[Beaps]

Yer still like they was in the cab (in my last photo)

[fagin]

OK.

Logic so far then is that either your Emotia's are broken or there is a problem with your 360 / VGA lead.

Get your laptop or PC, set the desktop resolution to 640x480 and connect that up to the Emotia.

You should get the LED 3 light up.

Try connection again to your PVM via svhs and report back.

[Beaps]

Ok, let me try that mate

[Beaps]

Balls, laptop won't go any lower than 1024x768, even in 'list all resolutions'

[fagin]

You can force it lower manually, but I'm not sure I can bear that pain of trying to explain it all.

You really need to try another VGA source to establish a problem with your source (which there shouldn't be) or the VGA cable (again I doubt) or obviously the Emotia.

One other thing worth trying..... have you swapped out the Extron PSU for another?

[Beaps]

I tried forcing it but it wont go lower than 1024x764

Any how I though let me hook up my Dreamcast via VGA

I hooked that up and here is what I get.



Yer I tried another power supply for the extron, same image

[fagin]

Have you got an internal / external sync button or menu option on your PVM - make sure it's set to internal.


These are Super Emotia's right?


Sounds like it's goosed based on the testing we've done.

I'm sure you have a sync problem.

One last thing to try - adjust the VHOLD on your PVM and see if it affects the colours.

[Beaps]

I have the sync set to internal and yer, it's the super emotia. Also I don't have a vhold on the pvm.

I guess this is the end of my testing

[fagin]

You've tried different sources and different target devices..... the problem persists. Logic dictates it's something around the Extron.

Try one of your other Extron's in the current PVM chain.

[Beaps]

I have tried one of the other extrons but they all give the same image. They all can't be goosed surely?
