Model 1 SEGA Genesis "High Definition Graphics" label vs. non-hi def label version

[Dashopepper]

I made the mistake of going out and buying The high definition graphics model 1 because after reading a thread I thought it would have either better graphics or sound then my non HDG model 1. Turns out the audio was absolutely horrible. I still use my non HDG Sega.

Maybe it needs a recap. Do you know what revision motherboard is in there?

Any pictures of the labels?

Clearly, your HIGH DEFINITION GRAPHICS Genesis Model 1 has a hardware issue. Many of the really early systems manufactured in 1989 are in need of a complete capacitor replacement and can have absolutely filthy sound if the caps on the audio amp are going bad. My earliest Genesis Model 1, which is a VA2 motherboard revision manufactured in 1989, had a serious amount of distortion and very muffled sound due to bad capacitors. Consider replacing the capacitors in that HIGH DEFINITION GRAPHICS Genesis Model 1 as MaxWar stated.

So if I did a capacitor swap would you think it would be the same/different/better in anyway then my other system? Unfortunately the non-HDG sega has a cd/32x attached to it so opening it up or checking the serial numbers wouldn't be very easy. But I had them running side by side and dont rember any startling graphical difference, only the audio.

Based on that picture your model isn't the one with the best sound, the best one has an FCC-ID code reading FJ846EUSASEGA. Just saying "High Definition Graphics" isn't enough to find a good unit. It could be sounding worse if the capacitors are starting to fail, but most of these systems are still fine as they didn't use cheap surface mounted caps and it's not really that old yet. I've come across several 70's era receivers working fine with the original capacitors, those tend to need replacing now due to aging. You can still try to replace them if you want.

Wrong. As long as it says HIGH DEFINITION GRAPHICS on the case, the motherboard revision is anything from VA2 to VA6, in this case, VA6 due to the shorter FCC ID. If it sounds like crap, it may be possible that the capacitors are crap, OR someone swapped the top on the console (not very likely, but it's always possible). Dashopepper should take a picture of the ports at the back of the console because if they're not placed where they should be, someone swapped the top off of a non-HIGH DEFINITION GRAPHICS VA7 Genesis Model 1 for one from a VA2 to early VA6 HIGH DEFINITION GRAPHICS Genesis Model 1.

This is OT, but since you know a lot about the hardware revisions, there's a mystery that has confounded me for years.
A friend of mine owns a game shop, and one of the old Genesis consoles he bought from a customer uses a different style of connection for the RF jack instead of the typical RCA. The only other time I've seen that type of jack, it was on a shitty famiclone that I bought in eastern europe.
It's an early model, and it came with a matching official RF box. It's not a euro megadrive or anything like that, but I have never been able to find another system like that, even online. Even hardcore Sega collectors I've talked to have no idea what I'm talking about.

Do you have a picture of the console and does it say "Genesis" or "MegaDrive" on the console? I wonder if it may be a Brazilian TecToy MegaDrive, but I would need a picture of the console to know for sure.

I don't suppose you took a picture of this jack? If not, could you describe it?

I don't have any answers for you, I'm just curious.
