The cable of for the PVM monitor has a direct connection, so it works fine with other systems that have RGB mods like the NES.

[ColecoRGB Help]

The Scart plugs into the PVM monitor with the Scart to BNC connector cables.

Here are the voltages from the sync output with the different options.

 

[ColecoRGB Help]

I wasn’t talking about your question, I was talking about something that has an extra potentiometer that was pictured.

[ColecoRGB Help]

Look at this picture.

The citrus3000psi RGB board’s sync doesn’t have a pot.

[ColecoRGB Help]

Ugh, it doesn’t work. -_-

 

I tried to replace the R11 and R24 with the new 15k ohm resistors, so their code is 18C.

18C = 15k Ohms

 

BTW, I don't know the 153 and 18C are the same thing for 15K Ohms or not.

 

[ColecoRGB Help]

Yes, both R11 and R24 are 18 , so I have to replace them with 15K.

[ColecoRGB Help]

I was right, 153 is basically 15K Ohm resistor SMD.

[ColecoRGB Help]

Besides, they have to be 15K Ohm resistors to get the sync to work.

 

BTW, I wonder what they look like? They are small that should have the resistor code, 153.

In your other thread, R24 looks like 18 ohms.  It should be 15K, according to the diagram and schematic.

Well, do I have to replace it?

[ColecoRGB Help]

I don't know this'll work for the Sync fix for the RGB mod.

 

By the way, I have a composite mod like this.

 

 

[ColecoRGB Help]

I am trying to get the RGB mod to work, I got full RGB, but how do I fix the sync?

Unless something has changed in electronics labeling I'm not aware of...5.6K and 5K6 are the same thing. Just two different ways of writing it with the 5K6 being more correct.

I can tell that they’re the same thing.

[New Coleco RGB board?]

I got it working on the PVM, but the sync issue and all green, so any ideas how to fix?

 

[New Coleco RGB board?]

On the bright side, I did fix my ColecoVision after the 5v mod, but I am still trying to get the RGB mod to work.

 

 

[New Coleco RGB board?]

I tried to check the voltage.

 

 

 

I did the other side of the SMD.

 

[New Coleco RGB board?]

The R23 has the SMD resistor code, 562 which is 5.6k Ohms. While the OSHPark says 5K6.

 

 

[New Coleco RGB board?]

Didn’t you see my work about the mod board I install? Did I do it right?

The CV and Adam have a 9928.

I see.

[New Coleco RGB board?]

Oh yeah, that would work.

 

I think the Coleco’s vdp chip could be either TMS9918 or TMS9928.

 

”2” takes YPbPr while “1” takes composite only.

Possible to use the SNES styled out connector for the RGB mod?

Cause if it is, it can be used because the SNES multi out takes RGB.

[New Coleco RGB board?]

How do I adjust R23 because my RGB board doesn’t get a sync.

 

Also, is it possible to use the SNES styled multi out connector for the RGB mod?

[New Coleco RGB board?]

I was trying to test before mounting the RGB output connector to be safe.

The bright side is, the grey scart cable works on my RGB modded 2600.

I'd highly recommend an 8pin minidin breakout board

though it works with a different style minidin than what you have.  Also I'd recommend getting proper individually shielded premade cables from retro-access or retro gaming cables uk.  The cables you want are mainly used for NES RGB mods.  Those gray 8 pin computer cables will have lots of buzz in the audio lines coming from the RGB lines.

 

So, I guess the grey cable sucks, and I need a different SCART cable?

Did I install the board correctly?

[New Coleco RGB board?]

I am having the hardest times to get the RGB mod to work on my ColecoVision. I got no sync at all.
