Old School RCA Monitor/ Reciever......come inside and have a look!

Robert Wallace · Oct 25, 2003

I bought this Old School RCA Monitor/Reciever at Goodwill for $40.00 a while back.

Its has decent composite output but when I use my JROK on this thing........the composite video sucks big time! There is no S-Video Options with this TV/Monitor but.........I see it has RGB capabilities!!!

Anyone know how I can wire this up for RGB? I'd like to ask here before I try it myself.

Im going to snip off the ends to a RCA Stereo/Composite cable for hooking up the Red Green and Blue......but Im not sure about the HSYNC and Ground.

Suggestions, Info, Help.....Welcome!

Almost forgot......Im going to hook it up to a Jamma Harness unless someone gives me a better idea.

Does anyone know if I can add an S-Video Input on this Monitor/Reciever?

Forget the s-video. Connect it properly using the JAMMA edge.
Use the true rgb and enjoy it the way it was meant to look.

If using mvs, connect top pin #12 for red, #13 for blue, bottom side #12 for green and bottom side #13 for sync.

Please, do not use the jrok composite out. I too have a monitor I use with my 1fz in true rgb and nothing else comes remotely close in terms of quality.

Robert Wallace · Oct 25, 2003

If I can add the S-Video Input........I'd really like to add it for my DVD Player and other stuff.

Yeah I would like to use the RGB but where do I connect the ground and HSYNC on the back of the monitor?

Magnaflux · Oct 25, 2003

I spy that rgb and sync under AUX 3 there on the back.
Just hook up the 4 leads and enjoy. I never used a ground for video, I just hook up the rgb and sync.

Can't say much about how to daisy chain such a device, but surely you can hook up that player via composite or something else while using the rgb for the neo?

Horiz. Sync? The boards output composite sync: connect that to the Video/Sync jack in the aux 3 input section. RCA jacks have two contacts each. Most likely Red, Green and Blue are the inside contact while the external contact is ground (you should be able to check this with a multimeter).

Robert Wallace · Oct 26, 2003

I have now wired this up to my Jamma Harness using the obvious Red, Green, Blue, and Sync Jacks.

But I dont get any picture on the screen, its just a blank White screen.

I did try hooking the ground wire to the Enable Jack on the back of the TV, this did nothing for me except for turning the screen black.

So I removed it and now the screen is just back to the white screen.

Anymore ideas to get this up and running?

I will take some pics of my wiring when my batteries finish charging.

:help:

Robert Wallace · Oct 26, 2003

The Screen is White, even before I turn on the power.
While the power on the MVS board is turned on it remains in the white screen.

You cant see it very good because of the tinted cover over the screen but the picture is all white.

Robert, my suggestion above was to connect the video ground to the external part of the RGB jacks (assuming the signal themselves are the internal contact), not to "enable".

Robert Wallace · Oct 26, 2003

Yes I have already tried that...... I tried a few different possibilities before taking any pics and posting here.

I tried the RGB with and without the ground wires hooked up.

Then I tried the RGB with the SYNCH plugged in and unplugged.

This is fairly similar to hooking up my Comadore 1084 Monitor to the Jamma Harness. The only difference is that Comador Monitor hooked up through a 5 PIN Din (or something similar) and this one hooks up through RCA jacks.

Here is the Comadore 1084 Cable I spliced to work with my Jamma Harness:

MKL · Oct 26, 2003

OK. So is it correct that the external contact of the RGB jacks is ground as is the case with the composite and audio jacks? If it is, then the key to get it to work must be that enable jack.
It may be worth noting that on scart TVs you enable RGB by connecting one pin of the scart connector to voltage (1-3V).

Robert Wallace · Oct 26, 2003

Yes the external surrounding on the male and femal RCA jacks is the ground connection.....its the same way with Stereo Jacks.

I wonder what that Enable Jack is for? Mabey Broken or Supergoose knows something about RGB via Television Sets?

I edited my last post with the picture from my Comadore Cable for reference.

BUMP

Well, this may seem like a longshot, but on many video processing IC's, they have an enable pin. You have to run a logic high signal to it to enable it. A simple 5VDC line might get it working. That's what I'd try. Hook up all the RGB and Sync signals, have the TV on, and a 5V wire ready to plug in. Have someone else look at the TV while you hook up the 5V signal to tell you if the video comes up or not. If it does, congrats, it works. If not, then you might have to try something else.

I can't seem to find anything relating to the RGB input for this TV, but you can probably order a service manual online somewhere.

Robert Wallace · Oct 27, 2003

Is there any chance of destroying the electronics inside the TV by doing that?

I dont want to blow up my TV. :loco:

I'll try a search on RCA Colortrak 2000 Monitor/Recievers, this is an older TV from the 1980's.

Well, it is slightly possible it could cause damage, but unlikely.

I searched for that model TV on the net for about 30 minutes, but couldn't find anything relative to the RGB input.

Hmmm i found this...Interesting read. Perhaps that set doesnt accept analog rgb?

Thanks for the link, that is the exact same RCA Model TV as mine!

I tried the Enable Jack with +5volts and I did get a picture on my screen but it is only black and white.

The picture quality was pretty good even if it was not color, I was using a 2 slot MVS running View Point.

At least there was some progress made, it should be something simple now......

I have tried several different connections for the ground wire for each of the RGB/sync/ and enable inputs.

The end resuld was the same: black and white picture. I'll post some screen shots of this soon.

This TV is in great working condition as far as watching movies and playing video games through composite or RF connections.

:help:

Reznor007 · Oct 31, 2003

Have you tried putting the RGB color signals on the outside of the cables? By that I mean attaching the color wire to the ring of the cable, instead of the center pin, and putting the ground on the center pin, much the same way coaxial SPDIF interfaces work.

Robert Wallace · Oct 31, 2003

I just tried your suggestion and it did not work.

Here is the picture I do get when the Enable has +5 Volts added.

The picture looks at home than in the post here, its not as blurry and dark.

WTF??? :help:

Reznor007 · Nov 1, 2003

Do you have any other JAMMA boards to try out? And have you tried adjust any of the picture adjustments the TV has?

It may just be wanting digital RGB instead of analog RGB.

Yeah I have a few Jamma PCB's that I've tried using: 2 Capcom games: Super Puzzle Fighter, Puzz Loop 2, and an SNK game: Search and Rescue, plus I have several 2 and 4 slot MVS boards.

The TV has plenty of knobs and switches on the front, none on the backside, Yes I have tried all of them.

I have tried many different grounding locations and everything else........

Now that I think of it Im going to ask JHendrix, I think he went to school for electronics. Afterall he is the only one I know who built his own RGB to NTSC Encoder for his supergun.

Does anyone know of another Tech fourm online?

Reznor007 · Nov 1, 2003

I built my own RGB to NTSC encoder. I ended up using a JROK though, as it was more convienient in the end.

You might check online for how to convert analog RGB to digital/TTL RGB.

Pocket Man · Nov 2, 2003

maybe 5volt on the enable line is too much i know that european tv use a line on the scart connector that switches between 16:9 and 4:3 and other modes maybe 5volt turns it into 50 hz rgb

Robert Wallace · Nov 2, 2003

The only power source I have is a Jameco power supply and it has +5 and +12 volts.

Well I think I have tried nearly everything I could to get this to work. Im probably going to give up on this for now.

It would have been great to get perfect RGB from this TV, mabey its just too old.
