Great video. I have a first gen Sega CD and the fuse is on top. I do need to replace it but I also checked the voltage on the power adaptor and the output is 12.9V! Might be why it blew. Luckily I have another 9V adaptor that fits.
So I checked by fuse and it is still showing continuity. Ive tried using both my Genesis 1 and 2 to test it and still nothing. I checked my power supply for it that is rated for the recommended 1.2A, and it shows 9.1V, so all is good there. The only thing Ive gotten it to do is briefly flash its LED, which would lead me to believe something may not be making a proper connection, but Ive tried everything. Any other common things I should check for?
@@LastGameHunter yea Ive tried that. Its frustrating because that flash of light gave me some hope. I got it to stay on for 2 seconds again, so Ill just have to mess with it some more. Thanks!
My MK-4102 wasn't getting power. I changed the fuse and still no power. I checked all the capacitors with my multimeter and they seem good... Any suggestions? I also made sure the power supply was good.
Might be unrelated, but I had a model 1 genesis that wouldn't power on when I took it to trade it in to a retro store. They used a bunch of chargers. I went to a convention and bought a charger from Tomee brand. Plugged it in and turned right on. Do you have another charger to try it?
I paid $20 for one off FB marketplace recently that included a model 2 Genesis. Thing is though, it had no cords at all with it and was "untested". I read that the CD used the same power adapter as the original Genesis, and I happened to own both a model 1 and 2 Genesis already. So I plugged it in, along with the gen2 and powered on the Genesis and no light whatsoever. Disc didn't attempt to spin either. Completely dead. I noticed on the bottom that the majority/all screws were removed from the CD, so someone tried to take it apart already to fix it. Do you still do repairs like this? What would you charge to take a look at it/repair it? I don't have a multimeter to check continuity for the fuse, but I do have a soldering iron. I just don't know if I have it in me to try to repair it or diagnose it if that isn't the problem...
Awesome good video. What a beautiful system! Console5 online has a ton of fuses now days 2.5 pico for 0.79c I am bidding for a no power Sega CD so wish me luck! 🤞
Or three you plug the wrong adapter with the wrong polarity. That is usually the case why these fuses blow. I know because I was dumb enough to use the wrong power adapter and blew my Sega cd fuse. I fixed the Sega cd model 2 by simply jumping the fuse with alligator clips. I recommend changing the fuse but since I don’t have solder skills I just jumped it.
Is there anything else that would cause it to not have power? My dad had given me a sega cd and genesis set that didn't power on. It was in the attic.... In florida.... Lol
I used a standard 3Amp automotive fuse and wired it into the solder ports of the original fuse. Workibg fine for 3 months now. Now my problem is the cd open switch. I have to set something heavy on the Cd Drive lid to play games. Lol
@@LastGameHunter to be clear, great video, material list in the video notes would be awesome. Is it supposed to be 2 amp? I feel I heard 2 amp but could be wrong
@@LastGameHunter Okay so I did jump it and now all I get is the sega cd background, just the moons a still image. No light working and no disk working just sits there
@@LastGameHunter I apricate your help I really do, So I broke out the multi reader and all of the pico fuses read okay, I get continuity on all 5 of the fuses, F301 and so forth, I have no idea what's going on at this point
@@LastGameHunter only asking cause I have the same issue,my dumbass 12 year old self fried it using incorrect voltage my freind and I at the time thought "if plug fits it must work!"
Love that you reused the old fuse posts with little trouble. So many remove the original fuse when its really not necessary. @8:08
very true ..thank you for watching
Gotta love a simple fix for such a common issue, can't imagine how many of these have gone to dust because of issues like this!
yes and that is a very sad thought
I know you hear this a TON, but man, you saved my Sega CD. To think - a quick $0.79 pico fuse swap was all it took! Thank you, kind sir!
anytime thank you for watching
Mine has this issue but I still am not sure how to do this
Just want to thank you followed your directions and now everything working great thanks again my friend
Thank you for the update
Can you use the same fuse that cars use for example the fuses a car has under the steering wheel usually or in the hood of the vehicle?
yes you can
what is the web page you went on to buy the fuse an the fuse holder
Not sure where you are in the world but here in Canada I went to Canadian tire
Can I use a fuse holder that uses the fuses for a car with a 2 amp fuse?
yes

try cleaning the connections (not plugged in) with rubbing alcohol.

Did you ever figure it out because I am having basically the same exact issue, sometimes the led will flash red and that's it

That is a great question, ill think about it.
I have a SEGA CD 2 which does not power on even after I've replaced the fuse. I don't know what to do with my sega cd now.

I've been fixing these things since April, I've done 10 but I have 2 when I changed the fuse they still don't work
Is there any power at all?
@@LastGameHunter no, I think I got a bad batch of fuses from ebay. I'm doing it blind with no multimeter but it hasn't been an issue til now
Are you US based? What would you charge to fix one/take a look at it if I were to ship you one?

at this point I just do work on my own gear as I can not keep up. Thank you for watching, any questions I will do my best to help out
what about the coincell battery... is there a point to changing that ?
Its not a bad idea to upgrade that as well, may look at that next.
@@LastGameHunter i dont even know what the battery does exactly.. i'm assuming it's for saving.?

I hope you do well
I bought a used Sega CD for cheap years ago expecting it to work but it didnt. I might need to do this one of this days.
it is so common
can i get links and or names of the parts used. i would like to buy something like that
In Canada I went to Canadian Tire and got the fuse in automotive and the holder as well, not sure where you are but there should be a store like that
@@LastGameHunter what what do you recommend for the amps and voltage of the fuse?
@@doc363 I used a automotive 2amp and the volts I think are up to 120/250
hey great video, where did you pick up that fuse holder? I only found one with a shorter wire.
At my local Hardware store here was Home Hardware
The Last Game Hunter I think I know what happend like the adapter has too much power.
The Last Game Hunter I’m gonna use the PCB for my Original Xbox console because the DVD Drive’s PCB is dead which shows rrod & error 12.
Thank you fixed mine.🎉

You are right that happens a lot... and I would get your fixed, now that the fuse will not blow bad other things can happen.
Is there anything else that would cause it to not have power? My dad had given me a sega cd and genesis set that didn't power on. It was in the attic.... In florida.... Lol
you will have to look at the capacitors on the board and see if they are bulging or leaking, I would say thats also a big cause
@@LastGameHunter thank you!
@@PSIGOD anytime I just hope I can help
Would a 5 amp fuse fry it?
yes it could for sure
I have a Sega CD splash screen, but that's it. Could the fuse be my problem?
no that will be something else ..maybe laser
@@LastGameHunter Thanks.
@@JetScreamer_YT anytime if I can help somehow let me know
@@LastGameHunter Thanks!
Could I use 5 amp fuse?
I wouldnt could harm the hardware

Is it a 2 amp fuse? Wish that were in the comments
2amp is fine
@@LastGameHunter to be clear, great video, material list in the video notes would be awesome. Is it supposed to be 2 amp? I feel I heard 2 amp but could be wrong
@@runwme81700 yes 2 amp is good
can you just bypass it without the fuse just to see if it works?
yes yo can jumper it
@@LastGameHunter Okay so I did jump it and now all I get is the sega cd background, just the moons a still image. No light working and no disk working just sits there
Well it tried to work for a few mins and now it just does nothing but a black screen as before even when I jump it, so back to emulation I guess
@@Scorpion24 sorry without seeing and testing everything its hard to say what to do other than changing all the capacitors

thank you for watching
I think I am going to do that with my sega cd. Nice vid.
Thank you
A classic console 👍🏽😊
Nice job!
Thanks bud!
This is interesting. I don't have a Sega CD though.
MR Josh no Sega Cd Shame Shame lol ...you need to get one down the road great system.
I will eventually.

O dear me! Just desolder the SMD Fuse and install a self-resetting SMD Fuse!!!
great idea
I dont suppose you do repair jobs?
maybe in time just trying to get caught up in life lol
@@LastGameHunter only asking cause I have the same issue,my dumbass 12 year old self fried it using incorrect voltage my freind and I at the time thought "if plug fits it must work!"
lol I did something like that as well@@Nzg41
@@LastGameHunter I don't have a soldering kit and to nervous about actually useing one,that I'll horribly botch the job and make it unfixable
Is there any local repair shops, for them this would be a very easy mod@@Nzg41
I have the same issue, I will try this and see what happens. Though I fear the cd drive probably doesn't work, it worked about 10 years ago.
PLEASE UPDATE ME
