- On this week's Fix It Friday, we take a look at the Sega Master System, Sega's first home console in North America.
These consoles often have defective controller ports and cart slots, but we show you how to diagnose and fix these issues!

I would not have expected it to be this simple. You were 100% spot on. I just fixed mine thanks to your video. THANK YOU!
Awesome!! Really glad to hear that this helped you out
Perfect. Greetings from Germany where the Master System had a good position in these days.
Thanks! It has been a while since I visited Germany and I hope to visit again when things go back to normal. The Master System has a good library of games and it’s fun to revisit
@@LIRetroGaming Since Land Of Illusion the Master System made a big step forward in games quality.
Ty George. Just picked up a master system with a faulty controller port, and now I know what to do to fix it. Looks easy.
Very well done. I can't believe I didn't think of this. I'll be sure to give it a try! :D
I just got an SMS from a pawn shop and neither port will go right on any controller and sometimes if you jostle the port a bit the machine shuts off, I suspect a bad or loose joint may be the case after watching this and will take a look at the inside
Thanks dude. I've never solder before, does that matter?
I would say that it’s good to get some practice before you try something like this. But this is not too difficult of a modification to do
Hi there! I'm currently having trouble trying to make the controller port 1 to work properly (up direction won't work). I have two controllers and both works perfectly on port 2, but any of them on port 1 won't work the up direction. Do you know exactly what are the soldering points that are directly connected to the PCB so I can try fixing them? Thanks!
Yes, when you look at the master system PCB you will see a row of five connections and a row of four connections where the controller port is connected to the board. Up is located in the row with 5 connections. I would start by adding fresh solder to all of the points in that row. Do you know how to use a multimeter to test for continuity? That will also help you to figure out if you have repaired the connection
@@LIRetroGaming Hi there and thanks for the quick reply! I'm out of solder flux and will buy this week to fix it, about the multimeter I have no idea of how to check them. How should I proceed?
Hi there! I was able to fix all the directions on controller port 1, but now button 2 won`t work! Any idea where it might be?
Is there a place to order new cartridge slots - I have one with broken pins
Yeah here is a link www.tototek.com/store/index.php?main_page=product_info&cPath=22&products_id=78&zenid=g28524dhb2c0fpplvp0rssv6s7
I my cart slot is bad. I tried reflowing the solder but it's in really bad shape. I may want to replace the slot and clean up the area..
There are replacement parts for the cart slot
I have this same board 837-6629, was having intermittent video, sometimes it worked sometimes it didn't. I replaced all caps, an now i have constant no video, clock signals look good, and reset/pause work fine, :S address lines stuck on low, any suggestion :S?
Start with reviewing the recap, I’m guessing that something went wrong there. Did you reflow the cart slot? Is the 7805 outputting 5v?
Hey I have a question, when ejecting the master System cartridge there really hard and I feel like I’m damaging something. Is it like that, I half to do a lot of strength and I have very rare games.
That is a little strange, it shouldn’t be so difficult to remove the games from the system
How about I send you my sega masters to fix and let me know how much you charge to refurbish it?
You can reach George for any repairs and mods at www.1uprestorations.com
I’ll be reflowing then cartridge slot on my sms tomorrow…hopefully successfully 🤓
Awesome! Hopefully this helps out!
@@LIRetroGaming So after a reflow, it now actually recognizes that there a cartridge in, but i get an error message with any cart. I dont see any bridges on the pins. Any idea what it could be now? The card slot plays card games flawlessly, and the built in games are good too.
