Plastic cable, eh?  Those things seem to disintegrate over time, so that could even be where the problem lies.

 

Just wondering, if you unplug the Adam board, will the CV part work as a ColecoVision?

I doubt it.

[Coleco ADAM TMS-RGB Mod Possible?]

Here is my board.

I socketed some of the chips (such as the VDP chip right before I added the RGB mod board.)

I understand that but you have to rule out any possibilities that the RGB board you installed is the culpit especially since the system was working before you installed it and for a short period after.

 

Remove the RGB mod, remove any expansion cards that might be installed, disconnect the Data Drive and Keyboard, connect to a TV via RF and then power on the system and see what you get. If it works, remove the RF cable and connect a Composite cable to the Monitor port and test again. If it works, reconnect the Keyboard and test. If it works, reconnect the Data Drive and test.  If everything is working using these steps, then reconnect the RGB mod being mindful that you don’t create any shorts or damage any traces.

 

Be extra mindful of the plastic ribbon cable that joins the Adam board to the CV board and that it is snuggly connected.

 

if you have an ADAM Printer to power the system, I would also consider disconnecting the internal power supply if you are still having issues. It looks like Jim Walters performed this mod and I know he thoroughly tests the whole system out, but you never know especially since you opened her up to perform the RGB mod.

 

i know all too well how much this sucks, how time consuming this all will be as well as aggravating, but at this point, there is no good alternative.

 

Good Luck.

 

 

Sadly, I do not have an ADAM printer. By the way, what if it doesn't work after I remove the RGB mod?

@NIAD The Adam was working fine with the mod right before it has the black screen issue.

This power mod I didn’t work on.

 

 

Basically, this is the ADAM I bought with the pre-installed power supply mod.

This power mod I didn’t work on.

If you press the CARTRIDGE RESET does the ColecoVision Bios screen display?

I tried, but it doesn’t show up at all.

[Coleco ADAM Black Screen Issue]

Hi, I have an ADAM that is standalone, but I have a stupid black screen, so any ideas how can I get this thing working again?

[Coleco ADAM TMS-RGB Mod Possible?]

I tried to clean and reseat the chips from the ADAM board, but I still got the black screen.

 

 

[Coleco ADAM TMS-RGB Mod Possible?]

I guess the ADAM board chips need to be reseated to fix the black screen.

[Coleco ADAM TMS-RGB Mod Possible?]

It was working fine until I get this stupid black screen with humming audio.

You sure it's not an issue with your cables? A loose connection or badly-shielded RGB cables will do that.

I doubt there’s something wrong with the RGB cables. I also don’t think there’s nothing wrong with those regular video cables either.

You need to be more specific.  From the pictures above, it sounds like you already installed the TMS-RGB, but now you're saying you are preparing to install it?

Listen, I decided to give a VDP chip a socket, and then I install an RGB mod.

[Coleco ADAM TMS-RGB Mod Possible?]

The ADAM was working fine in the other day, so I have socketed the VDP chip just in case for an easier replacement before giving an RGM mod.

[Coleco ADAM TMS-RGB Mod Possible?]

Guys, I got a black screen with the humming audio issue on my ADAM, so how do I get it to work?

[Coleco ADAM TMS-RGB Mod Possible?]

I think the 24 pin to 28 pin adapter could make the no delay bios chip work on the standalone ADAM.

[Coleco ADAM TMS-RGB Mod Possible?]

Coleco Adam from XRGB mini via Composite vs Coleco Adam with TMS RGB on the PVM monitor!

 

 

[Coleco ADAM TMS-RGB Mod Possible?]

I found a solution for the audio, I tried to use the gscartsw switcher, and I got the audio working.

[Coleco ADAM TMS-RGB Mod Possible?]

I got some bad news, I got no audio while the ADAM has the buzzing audio while the RGB mod works on the ADAM.

[Coleco ADAM TMS-RGB Mod Possible?]

It is possible to do an RGB mod on the ADAM via the TMS RGB.

 

 

[Coleco ADAM TMS-RGB Mod Possible?]

I doubt the no delay bios could work on the Adam stand alone version because it doesn’t have the extra few holes for the chip, so it won’t be possible.

[Coleco ADAM TMS-RGB Mod Possible?]

Also, is it possible to do the No Delay Bios mod for the Adam, or it could only work on the standard ColecoVision?

[Coleco ADAM TMS-RGB Mod Possible?]

Despite Adam has a TMS9928A chip, it has a composite output without any modifications. I think.

I'm pretty sure they have the same TMS - 9928A chip.  Thus, it SHOULD work....never tested... lol

I bet it could work, so it should have the same VDP as the regular Cole  Vision.

 

Coleco ADAM + TMS-RGB + Virtual Disk Drive + Internal Power Supply Mod = Ultimate Coleco ADAM!!!

[Coleco ADAM TMS-RGB Mod Possible?]

Hi, I have an honest question about the standalone ADAM computer. Is it possible to do the TMS-RGB mod on the Coleco ADAM? I am not sure the VDP is the same as the regular ColecoVision’s VDP or not.
