Sega Genesis Model 2 - Black Screen: Diagnosis and Fix 

Oh I see the problem. The owner used it as a soccer ball.

Thanks for the tip to move the cart a little. That worked. I'm having an old school game party in a few days and I was freaking out that it wasn't working. It's still a little temperamental but that's part of the classic gaming experience.

Thanks for making this video. I've got a model 2 that's used to work and has been sitting idle for some years and now it has this problem. Going to give the motherboard a close inspection this weekend using your video as a guide.

🙏 you saved a Sega Genesis this day, sir.

Hey!!! Thank you! I pulled my original Sega Genesis from being in storage for 20 years and worked through your suggestions. It worked! With your advise and GREAT simple video I found it’s the cartridge slot port on the PC board. I wiggled the cartridge as you described and the game worked. Now I know where and what to fix. Thanks for saving my original Sega!!!!!! Thank you. Thank you. Thank you. 🙏

Just fixed my Sega Genesis 3 thanks to your suggestion on the corrosion problem and that was what the problem was there was corrosion in it I appreciate it man great video keep up the good work

Dude. Thank you. Had one lying around for some time which did not boot. I resoldered, inspected and did almost everything to fix it. Even replacing the cart connector.

Very interesting video. Well done diagnosing!

Now time to fix my old dead Sega Genesis and play some Sonic 2

When you first flipped it over I was like “wtf is that bodge wire for??” I soon found out 😂 Nice repair. New sub, I like your videos.

Having the BSOD with mine that's been in storage for some time. We got it used many years ago. I decided to clean it with isopropyl and qtips. The amounts of nicotine on the circuit board were disgusting. Didn't see any broken traces but didn't test power yet. Going to test it tomorrow, hoping for the best. Thanks for the video!

I just encountered this same problem on a genesis I bought to fix. It was B10. It's strange though, the trace going to the south of the via was fine, the trace heading north from the VIA was not getting a signal. I put in a wire from B10 to the VIA going to the processor on the underside. Following traces took way longer than it should, and my wire is currently holding on to the via with hopes and dreams. Thanks for making this video!

💯 Worked for me! Cheers! 🥃

Thank you Bru I rlly predicate, W video

Same exact problem, trace from A8 to pin 166 of the VDP (VA13) was broken somehow. Wired it up, it works again!!

This video game me great guidance 🙏

I have a Model 1 that only cold boots. Once the console is warm you can cycle power and it will black screen. If you ran it longer it will have to sit and cool off longer before you can boot again. It doesn’t seem to be getting excessively hot and I’ve swapped tons of components with a known-good console. No dice.

Many thanks! Got a couple "dead" machines working again. Seems the corrosion around the base of the cartridge port is a common issue.

Are the power input pins on the sega chips always in the same spot? Example pin 1 on each chip? How do you know which ones to test with a Volt meter?

I have a model 2 Genesis. Used to boot up fine but games and console were dirty. i was running into a problem with the power port. the solder joint was cracked, i used a heat gun to heat it up and now it does not wiggle anymore. I booted it up and it was fixed. Then i took the console apart, cleaned inside and put it back together, and all I can get now is the black screen issue. very annoying. seems if I didn't try to clean it at all, it would still be working
