32x rolling color (sync?) issues

[nova1313]

I'm having problems with my 32x. The color rolls/flickers when playing 32x, genesis or sega cd games with it installed. Removing the 32x the color/picture are fine for genesis/sega cd.

I replaced the genesis 2 to 32x link cable with one from racketboy 2-3 weeks ago and the problem did not go away. I was concerned that the sync was maybe messed up.

Today I recapped the entire 32x and the problems did not go away (have spare sets of caps if anyone needs them, pm me and we can work out a price!). Some games it flickers faster, some it flickers slower..

Any ideas what the problem could be?

Wow that is trippy, did you slip something in my drink? I really don't have any answers for ya, I hear a lot of people talking about the ribbon cables but I don't think it was the same problem.

I've fiddled with the white cables but no luck. oddly the more I twist the main board up at an angle the slower it seems to roll. I've tried re-soldering the connections between the main board and the card board but no luck.

I'm about to call it a day and just get a spare off ebay next week. My only hesitation is that it could possibly be the sync off my genesis since the composite out doesn't use that without the 32x connected. A spare genesis 2 shouldn't be hard to come by though if that is the case.

Wanted to follow up on this. I picked up another 32x and experienced the same problem. I took the 32x up to a tv instead of the receiver to projector hookup and don't see the problem there. Something with the 32x signal and the projector/receiver is messing it up. I have up-scaling turned off and pass-through on both but still see the problem.

My projector composite input doesn't seem to work so I don't know if it's the receiver or projector at this point.

Projector is Optima and receiver is Yamaha.

Now you mention that, I bet it doesn't like the 240P signal.

Interesting.. adding 240p to my google searches pulled up a ton of issues. I'll have to check if the Sonic 2 special stage (480i) works okay via 32x.

If it fails, my receiver won't take S-video so I guess I could convert all the systems to SCART, get an external scaler then go composite to the receiver.

[bryan_65]

So is it the receiver or projector that does not like the signal? Does the projector have any inputs to use? Maybe only use the receiver for sound.

[nova1313]

Can't be sure.

My projector (Optima HD20) was refurbished and I never tried the composite input before now. The composite doesn't seem to take input from anything I give it. So I can't be sure if skipping the upscaler on the Yamaha receiver would fix it.
