Help with Genesis 1 RGB on Commodore 2002 monitor

When I flip the RGB switch on my monitor I get what looks like a scrambled cable channel for a split second, then black screen. I can flip the switch back and forth to get the same result.

I'm using the following cables with a gender changer.

Any ideas? Thanks

 

I don't know if it makes a difference but sounds like you're trying to use a 32X cable adapter, without the 32X.
Console RGB is analog. Make sure the monitor isn't set to digital.

Video resolution could be an issue too. Commodore 2002 is rated for only 200 vertical pixels, less than even the NES outputs. Let alone Genesis.

Those two cables were recommended so I could add a 32X later without needing a different set. Do you think I was misinformed? From what I understand, the 2002 is basically a 1080/1084 and those appear to work with the Genesis. Analog RGB is set on back of the monitor. Thanks for the monitor PDF also.

 

Does anything happen on composite?

 

Yeah composite works great. I just had NES hooked up to it.

 

It appears the fancy cable I ordered has Csync wired to ground.

 

never had a 2002 but have dealt with some 1084s models, some of them need c-sync instead of composite as sync to display right image

 

I painstakingly wired each pin (R,G,B,Csync,Ground) with the same results. I'm suspecting bad caps.

I just confirmed Composite is working on the monitor and I'm going to dig out my Genesis RF adapter to test that. I also know audio works from the Genesis headphone jack. I've tested all the cabling I ordered and I'm pretty sure that all checks out.

Here is the best video I could shoot using the crappy camera on my phone. What you can't see is that you can actually make out the SEGA logo screen and everything but there is just too much latency on the camera to tell. The colors all seem there but sometimes it has a yellowish tint.

Any help is appreciated Thanks!

 

More updates.. So I just ended up splicing Composite and Ground into an RCA and testing that way. It looks horrible as you would expect for Composhit.. but it works. I noticed toggling the Comp/RGB switch seems to wiggle the screen like maybe something is wrong with the switch. I wonder if this could be somehow messing up RGB mode?

 

Wiring directly with a spliced CAT5 cable but using pin 8 (H/V?) instead of 7 on my monitor made it work. The colors are dark with no resistance. The cable I bought had all the internal components but when I swapped pin 7 to 8 at the DB9 end it didn't work. So now I need to find another cable.
