I'm trying to use the 34 pin RGB input port on the rear of this monitor.

Unlike its later counterparts, this monitor looks like it needs to have some pins tied high or to ground to configure the mode (analog/digital RGB) and enable/disable overlay.

Looks like I'm going to need the pinouts of the port and the truth table for the mode pins.

All I'm trying to do is drive it with RGB + composite sync from a video game.

Thanks in advance.

From memory the RGB/NORMAL pin on the Multi connector needs to be tied high to enable the RGB input (pin 33). From memory the RGB input is always analog, the external adapter to connect a CGA PC to these monitors contained a circuit to convert TTL RGBI to analog RGB.

I've uploaded the service manual for the KX20PS1 (the euro version of this monitor which has the same multi input) to my web space. PM me for the link if you (or anyone else) need it (I'm not posting the link as I don't want it ending up in google).

Google for the KV-1311CR, KV-2011CR, KV-20XBR, or KV-25XBR. They all have the same port (the 1311 lacks a few pins) and I know they have been discussed on some news groups and web sites. I use the RGB input with a component to RGB converter to deliver an excellent picture from DVD, or satellite.

Here are some shots of the KX-1901A owners manual showing the pinout on that. I hope the photos are OK, but if it's hard to see in the photos, I can manually type it.

Cool, thanks!

I remember reading that the euro version was multistandard as well? All of the later profeel monitors I've owned except the 2030 and 2530 I use on my bench were multistandard.

Did the euro version have the super fine pitch tube?

The euro KX20PS1 and the 27" KX27PS1 are both multistandard (PAL, NTSC, SECAM) as are the PVM2130QM (I'm watching one now) and PVM2730QM Profeel "cube" monitors. The differences in the models numbers are due to the way tube sizes are quoted, the US 2530 and the Euro 2730 use the same size tube.

My KX20PS1 is in storage with a problem I haven't got around to fixing yet, I haven't had a good look at the CRT yet.

Wasn't the name "Profeel" only referring to the KX-4200, KX-1211HG, KX-1901 & KX-2501? I know that the KV-25XBR which replaced the KX-2501 wasn't called Profeel... Not sure about PVM series.

In the USA, the PVM2030 and PVM2530 had the name "XBR Pro" (and I think there was later a 32" version, too). They may be the best NTSC CRT monitors ever made. I have a couple of the 25s that I want to sell, but I haven't figured out how to attempt to do that yet. They are in great condition; maybe I should try Ebay? Shipping would probably be expensive to anyone out of my area.

My PVM-2530 (Canadian model) which I've owned since new had a black label across the corner with "Sony Design -Cubic Profeel!"
Don't exactly know why they used the "!"?

It seems they carried the same design/marketing plan with the 2030 and 2530 they sold over here, since it is NTSC only. A production change on these about half way into their production gave them a S-VHS connector on the input board.

I was relieved when they went to the PVM2950Q, which was sold here, was multi system and had plain old 5BNC for RGB. There sure is a lot less inside these compared to the 2530.

In the USA, they had a similar label but it just said "Sony Design".

Hello to All,

Very interesting this US 34 pin connector!

Here in Europe we have the SCART plug with 21 pins.
(see picture)

It was invented & made mandatory in France for all color TVs having screens above 5" from the mid-70s onwards. It was then standardized pan-European by the EEC in Brussels.

That connector was only used on those few Sony monitors as far as I know. Here in the USA, we never had any standards for A/V connectors, just what the manufacturers supplied. SCART would have been nice and convenient, one cable for input and output audio and video. Also, then maybe we could have had RGB as a standard instead of the silly "component video" (YPrPb/YCrCb) that has become popular.

Thank you for the complete SCART diagram.

The RCA CTC-140 from the 80's had a connector that looks the same a a SCART connector. Does anyone know if it has the same pinout?

Was the CTC-140 made by Thomson? Every Thomson set that I have seen has a SCART connector, including some sold under RCA badge here. However the model numbering for RCA sets sold here is different. No RCA that I have seen here has a CTC-xxx model number, so they could be entirely different sets.

While the 21 pin SCART connector is a standard not every manufacturer that used it followed the standard pinout. Some manufacturers changed the functions of a few pins here and there. Some Euro model Sony's (including the KX20PS1/KX27PS1) don't play nice with standard SCART RGB cables. Some manufacturers used a couple of pins for data to control their matching VCRs. Some used the RGB/composite switiching pin to switch between 4:3/16:9. Most cheaper sets don't have an RGB input at all.

Some domestic Japanese gear uses the same connector with a totally different pinout (this has caused endless confusion for European gamers playing with imported Japanese systems). That pinout is here: http://www.gamesx.com/avpinouts/rgb21pinj.htm

It was instorduced just before RCA was bought by Tomson, then continuted by Thomson. It's the only US set I've ever seen with this connector.
