atarigal Posted May 17, 2011 Share Posted May 17, 2011 Has anyone else had this experience? I tried Googling, and it seems like lots of people ask this question but there are no solutions to be had. I have two Sega Genesis 1 consoles, both confirmed working, both power up when you turn them on but no audio/video signal is sent to the TV. I've tried both units with both a Sega AV cord and various RF cords and different games. I have a Vizio 32" 720p from 2008. Are they just not going to work with my TV? We do run the Ataris, Colecovision, Intellivision, Wii, Flashback, etc on it fine so it's not the cables we're using. Quote Link to comment Share on other sites More sharing options...
Tempest Posted May 17, 2011 Share Posted May 17, 2011 Yep, I had the same problem. I'd actually get a picture on occasion, but the sync didn't last and it would go away after a second or two. Tempest Quote Link to comment Share on other sites More sharing options...
Reaperman Posted May 17, 2011 Share Posted May 17, 2011 (edited) It happens to me too, and I had heard that it's because of certain video modes that genesis uses (specifically 240p). Certain games almost work. Phantasy Star 4 almost works for me except for the cutscenes and the sega logo, but the *vast* majority of games just give me black screen. My solution was to get a video scaler, and run the genesis through that first. I found a deal on one of these, but I'm sure newer units are better. I expect that after about a decade, we'll have to use a scaling device for all of our game systems. I didn't try connecting through a genesis RF connection, but running its composite signal through a vcr first does not help.

Underball Posted May 17, 2011 Share Posted May 17, 2011 It's the TV. Specifically Vizio, and many of the "discount" brands. My Samsung LCD from 2009 supports 240p, so all of my classic systems work with it. Quote Link to comment Share on other sites More sharing options...
Tempest Posted May 17, 2011 Share Posted May 17, 2011 I think my TV is a JVC, I'd have to check. Tempest Quote Link to comment Share on other sites More sharing options...

Koopa64 Posted May 17, 2011 Share Posted May 17, 2011 I feel the need to quote myself here. The Sega Genesis doesn't have a constant horizontal frequency, which can cause compatibility problems with some TVs as noted by Reaperman. Also, just because it's a similar subject, the NEO-GEO (either MVS or AES) has a very odd sync frequency. Where NTSC is 59.94 Hz, the NEO-GEO's video signal sits at 59.18 Hz (approx.). Some TVs (like LCDs) can't handle this kind of sync rate, while typically CRTs are flexible enough to work with it. Your welcome. Quote Link to comment Share on other sites More sharing options...

My Samsung LCD from 2009 supports 240p, so all of my classic systems work with it. My Samsung DLP from 2007 is the one giving me issues, so their support must be a bit mixed. It does everything else that I've asked it to though--n64 works fine, but I haven't tried my neo geo on it. I really think support for old video will get worse and worse until we're all on scalers though. Edited May 17, 2011 by Reaperman Quote Link to comment Share on other sites More sharing options...

Guess we won't be getting one of those. I'll give the system to the kids to take to their dad's as he still has a tube TV. Quote Link to comment Share on other sites More sharing options...

PsychoKittyNet Posted May 17, 2011 Share Posted May 17, 2011 I find the best solution is just to use a small CRT. Bout a nearly new one, 19 in at a thrift store. Works great and does not take much room Quote Link to comment Share on other sites More sharing options...
Tempest Posted May 17, 2011 Share Posted May 17, 2011 I use an HD CRT, they're the best of both worlds. If you can find one I highly recommend them. Tempest Quote Link to comment Share on other sites More sharing options...
atarigal Posted May 17, 2011 Author Share Posted May 17, 2011 Yeah, if we had more room I'd just get a CRT. They have tons of them at Salvation Army. We just really don't have room for that at the moment. Maybe when my daughter cleans out her very messy room we could put one in there.

sheath Posted May 17, 2011 Share Posted May 17, 2011 I don't think it's just LCD TVs, my Toshiba 40" LCD works fine with my Genesis and Master System. I have had the same problem with every Hauppauge and Avermedia video capture card I have tried so far though. These encoders seem to screw up with Genesis and Master System Composite and RF outputs for some reason unknown to me. I recently also discovered that Destruction Derby and Doom on the PS1 causes very similar problems in S-Video. On my capture cards the colors turn to black and white and sometimes the video doesn't show up at all. I am not sure what the problem is, and I wish there was a way to know for sure before buying an expensive LCD TV or capture card if it was going to work. My older Ati All in Wonder capture cards worked fine with everything I tried them with, but the newer ones can be a cap shoot. Quote Link to comment Share on other sites More sharing options...

That specific unit won't work, since it does not take composite input, but there are enough similar devices to do it. I got mine for ~$15 shipped (used), so they really don't hold their value. Mine only outputs VGA, so I probably can't recommend it over the competition, but it works for my setup anyway. I can't hit ebay from where I'm at or I'd link you to a reasonably priced device that will do it, but I'm sure somebody else in here can help out.

Reaperman Posted May 17, 2011 Share Posted May 17, 2011 (edited) Here's a link to one: eBay Auction -- Item Number: 230620725892 I can's speak to the quality of the unit (this type of device varies greatly), but the price seems right. It takes composite or s-video signals, and outputs on HDMI. It's kind of a spartan unit, without options for aspect ratio, but your tv can hopefully handle that part.

Eltigro Posted May 18, 2011 Share Posted May 18, 2011 I haven't heard of this. Is it just the Genesis 1 that has trouble? I have a Genesis 2 and haven't had any trouble with my Westinghouse LCD which is certainly not a top of the line model (it supports 1080p, but it was the cheapest one that did so).

I'm not sure, but googling the problem I did find quite a few people asking about it, but few real answers. So I guess it's just SOME TV's that don't support the 240. How long have you had your TV? Mine is about three years old (got it during the 2008 Olympics). Quote Link to comment Share on other sites More sharing options...
Koopa64 Posted May 18, 2011 Share Posted May 18, 2011 The Sega Genesis doesn't have a constant horizontal frequency, that's the main reason why you guys are having so much trouble getting your LCD displays to work with it. Unfortunately, there really isn't much you can do to fix this problem, outside of buying a new TV. If you are though, Panasonic's Viera Plasma sets work with the Genesis perfectly (NEO-GEO as well).

The problem is not specific to the model 1 version of the genesis. I've tried all major revisions and the gn twin clone. This is a topic that does come up on this board every so often, so I've had a number of rounds to try different combinations. There's really no spec to look for when selecting a new TV either, making it a complete gamble every time. It's not like they list archaic scan rates and resolutions on the box. This all kind of makes me curious about a JVC LCD that I picked up somewhat recently. Anybody want to wager?

Mine is about three years old (got it during the 2008 Olympics). Mine is probably about two years old. It's a Westinghouse model TX-42F810G. The Genesis is connected via rf, and is daisy chained with an NES, a Jaguar, and a TG-16 rf connections between it and the TV. Last time I played my Genesis on it was a few months ago. I had just bought Truxton and played it for a couple hours. Right now I put Thunder Force II in and I'm just letting it run the attract mode to see if anything pops up weird.

atarigal Posted May 18, 2011 Author Share Posted May 18, 2011 Is the NES (or other systems) the same resolution as the Genesis? Just wondering what else I might have this issue with. I sent one of the Genesises (Genesi? ) with my daughter to test at her dad's tonight... he has an old CRT TV. Just to cover my bases to be absolutely sure they are still in working order.

nightwheel Posted May 19, 2011 Share Posted May 19, 2011 I have yet to try a Genesis Model 1 on my LCD TV. I have a Hannspree 28' full HD LCD TV But with the retro systems. I have yet to run into any problems except with Quadrun on the Flashback 2. For some strange reason, when I fire that game up. It works for a few seconds, then my LCD loses signal when it start to say "Quadrun Quadrun" Quote Link to comment Share on other sites More sharing options...
