That's exactly why I'm lieing and telling him that it won't work if you leave them floating.

It works floating on some consoles, but not recommended. All my american consoles when left floating boot to american mode.. But I highly advise AGAINST activity like that..

[BlockABoots]

It won't boot with all of the pads cut. You need to bridge JP1 and JP2 for NA/60

Actually the internal flip-flops will have a default region even if those traces are gone. IIRC it's set by default at 60hz, can't remember if the default region is Japan or English. It's probably Japan. You can see some remnants of the traces. Just add small wires where the traces would go and you're ready to go.

Ok i have 2 conflicting suggestions here, Robivy says to bridge JP1 & JP2 but then villahed says to bridge JP1 & JP4!?

[evildragon]

On all my Sega consoles, american models, with all traces cut and nothing pulled low or high, it defaults to 60Hz ENG. Just saying.

[BlockABoots]

Yeah i have tried bridging JP1 & JP4 and all i get is the red screen still, and bridging JP1 & JP2 i get not video display what so ever

JP1 and JP2 will set your console to american region, but this is a japanese console.

[BlockABoots]

JP1 and JP2 will set your console to american region, but this is a japanese console.

Yeah JPN region is JP1 & JP4 which I have tried bridging and all I get is a red screen on turning the console on

[lumclaw]

Did you bridge JP1 & JP4 (right) or JP1 to JP4 (wrong)?

[villahed94]

Did you try with different games?

[BlockABoots]

Yeah tired with 3 different games from 3 different regions

If you used an NES regulator, the 7805s are most likely gone. The NES regulator outputs AC, while those 7805s use DC. Replace them and use a DC regulator.

So will any of the 7805s on ebay work?? 5v 1.5a?

I saw those when I took apart the genesis, I don't think it will be too hard to desolder the old ones and solder some new ones in, but is there any guide out there for pointers?

[villahed94]

Yes, that 7805 will work just fine. I recommend getting either ST or Motorola 7805s.

I found a Genesis model 2, a/c, rf, 2 controllers, 32x, attachment cable, and 3 32x games at the goodwill today.

After a bitch and a half mixing and matching parts with my other Segas to see what works and what doesn't here is my problem.

The model 2 Genesis doesn't seem to recognize controllers being plugged in. I tried 3 different controllers and none were usable. The contacts seem fine, and the controllers aren't the problem. The plastic bits in the ports that the contacts stick out of seem to be a little warped or loose (like the past user yarded on it a few times to get a controller out). Any idea what I can do?

Do you think it would be the same problem and solution I found here? :

Or do you think it's just the plastic getting in the way?

Thanks in advance.

[villahed94]

I think the controller ports are bad. The ports can be replaced, though.

[lumclaw]

The connector itself is obviously generic, bajillions of uses. Finding one to fit nicely might be tougher.

[kennerguy66]

I think the controller ports are bad. The ports can be replaced, though.

Should I open it up and poke around to see if that's the problem? Anything I should look for?

I was planning on just flipping it on ebay, so if it's not an easy fix I might just sell it as a parts/project Genesis. I don't want to waste much time or money with a fix.
