Sega Genesis model 2 black screen

[Flamzeron]

As the title says, I'm having some trouble with my Sega Genesis model 2. I recently found it in my garage, along with my controller and AC adapter. I cleaned everything off with disinfect wipes and isopropyl alcohol. However, I couldn't find the AV cables so I bought the Tomee brand cables. They seemed to fit fine but when I tried to play the Genesis on my TV, all I got was a black screen. On my TV, the labels on the screen when you switch to a source (HDMI1, etc.) disappears before showing whatever I have plugged in. The Genesis seems to be able to turn on fine (I don't remember if the light on the Genesis is supposed to be anything other than red when it turns out). I tried cleaning the connection ports on the Genesis with a q-tip and isopropyl alcohol and checking if there was any dust within the pins and I still got the black screen. I also cleaned the cartridge port and the game I was trying (Mortal Kombat II) and it still didn't work. What else can I do to see if it can work? Is my Genesis busted? I would prefer to try and get it repaired if I can instead of buying a new one. Assuming all it is the AV connection, is that easily repairable? Thanks in advance.

Try an rf adapter, any one with the RCA plug on the system side should work. It'll help narrow it down. Could be a number of things

It could be a defective cable. I've had similar issues like this in the past with other consoles and aftermarket cables.

You can always run the audio-out to a stereo or something else to see if the games are booting. If they work you've either got a bad cable, bad video out on the console, or your TV doesn't like the Genny's composite output.

If you've only got one cart to test it with you're kinda in a pickle since you've no way to determine if it's the cart or the console that's defective.

Okay, I'll try that. I couldn't find my original one though, so I may have to buy another.

This doesn't surprise me. Is Tomee a good brand?

I have others. I also tried the six pack one that came with my Genesis but it didn't work. I have one of those clone consoles, so I was able to see if my games worked period, which they seem to do. My controller worked as well.

Actually, recently, I found another AC adapter with the same yellow thing on it that the Genesis model 2 has on its AC adapter. Would the AC adapter be an issue? I'll probably try and see, but it would never occur to me that the AC adapter would be a problem.

I can't speak for their cables, but Tomee knockoff classic controllers are crap. Very thin plastic, very weak, don't last long, and don't handle as well as an original. Back when I got a supaboy v2 through ebay the seller gave a free snes tomee new pad in box with it, and man it sucked bad. I also before that had a USB one that was garbage too but risked it locally for $5 a few years earlier so I can say with time *years apart* they didn't care to improve things.

The AC adapter could maybe be a problem, if you have another just make sure the voltage and +/- setup is a match.

[Flamzeron]

I tried the other AC adapter, but I still had a black screen. The one I was using before was the mk-2103 and the other one had a higher voltage, I think, so it probably isn't meant for my Genesis anyway.

On the subject of these modern knockoffs, which one is the best? Or do they all suck? I try to get the original stuff as much as I can, but some of them are hard to find and if one is the best then I wouldn't mind using them.
