  • Hi, this 'trying to fix' video shows me attempting to repair Sensible Soccer and Paperboy Game Cartridges on the Sega Mega Drive also called the Sega Genesis in the USA.
    Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
    I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
    Many thanks, Vince.

    Each episode is like witnessing a train wreck from an actual diagnostic perspective, but that’s part of your brilliance. You’re learning, taking chances and once in awhile you actually fix something. All in all, you epitomize the “never surrender never give up” attitude.

    good work vince. bloody good to see someone repairing things. and especially keeping the retro stuff alive. and using the isoprop is spot on for cleaning electronics i use it when i fix old c64 and amiga motherboards etc. another really good way to clean those 'fingers' is using an eraser / rubber (for removing grey lead etc from paper)

    I did'nt think you would be able to fix any of them so i was amazed when you fixed the soccer one........i think it was really clever vince well done.The other game i think you gave it your best but like you said if that big chip is the fault there would be no way to fix it....i really enjoy these fix it videos they are very entertaining and my favourite on youtube at the moment..... i like the way you explain what you are doing and what you are about to do ...you really are very calm and patient with everthing you do.... you are a real inspiration ......good luck for your next fix it project.........and thankyou for sharing them.....

    The "mystery" of the direction of the testing suggests diode reverse polarity protection. The 3.14V in that battery at that age suggests someone did have a go at fixing it, I wouldn't expect a 20 year old battery to be pi volts. Good work spotting the broken traces :) Remember if you're running a jumper wire anyway, you don't have to solder to the thin, damaged trace but can join the big pad to the IC pin directly.

It sounds like me trying to fix things, even knowing that there is no way that I'll fix it and more likely I'm breaking it even more.

    Just a tip: The component you were wondering about was clearly marked "C2", i.e. the second capacitor used in this pcb. PCBs usually have such markings(C for capacitor, R for resistor and many more like that, whose meaning you can easily find online) that make the identification of the components easy

    In my shop, rules to troubleshooting, #1 check all connections and traces or solder joints. #2 check capacitors and resistors if any. #3 check all transistors if any. #4 chk all button type batts. Or high output button type capacitors if any. Then check "IC's" or integrated chips. Any of these will cause failure, duh! But if all seem fine. It will most likely be the logic of the IC! You can if you're proficient with soldering iron jump 3/16 th " to bridge a gap no wire needed. Wire will add resistance.

    @televisionandcheese Před 5 lety +3

    Whenever my games didn't work, I'd just put them in at a slight angle or half way in and that would get them working.
    Those few flashes you see when you turn it on without a game (sometimes with a few click noises) are just interference of the RF signal for video out, they happen on every game, even working ones, you just can't tell as the picture signal is much stronger and overwrites it pretty much.
    That central pin at the back with the thick trace was for ground connection, just the returning current from the cart to the power supply, that's why it's connected to all of them.
    I believe the rom chip had just died of old age, everything does, no matter how reliable. When you moved it along one all the voltage going through the cartridge and back to ground would have been going through a data line on the rom chip instead of back to ground. That's definitely killed it now, 'putting the nail in the coffin' I guess haha. I believe those crazy colours on screen after that was the irregular voltage coming back the wrong way causing hell for the mega drive, I'd be very careful doing that, it could also kill the megadrive :/ , luckily you didn't have it on like that for very long and it didn't do any damage.
    I'd keep the circuit board of paperboy and only toss the rom chip, then you can get a replacement ROM of any game, and use the board for that, and essentially make reproduction cart. Then there'd definitely be some money profit there. Outrun goes for about 35 in British Pound!
    Really great to see sensible soccer working once again! :)

  • @GadgetUK164
    @GadgetUK164 Před 5 lety +17

    A few more tips - get some Chip Quik flux (pricey) or Amtech flux. That will help your braid soak up all the solder on the surface of the pads. Also worth putting tape over the edge connector contacts to mask where you are about to solder. If you use flux, and have tape over the pads, the solder wont flow all the way over the pads. You can also use either kynar or single strand transformer winding wire (super thin, like 25% the thickness of Kynar).

    For repairing traces I would recommend getting some car rear heated screen element repair paint or in a pen as its very easy to use to make fine traces as we used to use it when overclocking old AMD chips and motherboards and is pretty resilient too.

    If you haven't got the right bit to undo the sega screw to hand, you can melt the end of a cheap empty see through biro and quickly place it on the screwhead (doesn't damage the cartridge plastic) , i normally got 2-3 undos before having to remelt the plastic when refurbing game gears, my screwdriver bit had worn out at the time.

    The mask ROMs do fail in these carts. You can replace them with a programmed 27C400 / 27C800 / 27C160 EPROM depending on what size the game ROM file is. The battery is for saves - not all games have save RAM onboard. That small yellow component you pointed to asking if its a resistor or cap, it is a capacitor.

    When you next try any projects and you get broken tracks, try some silver contact paint. A small brush and then a little paint, rather than solder, or use your heat gun to do the job. Try not to use solder iron on really small tracks. A small cheap ESR meter might help with cap testing. ? WELL DONE !!

    Hey perhaps you can give me some ideas. I bought a Sega genesis game on Ebay, Grindstormer and the picture is clear and clean on the Sega start up screen, the Grind Stormer start screen, but when I start playing the actual game its stuck on a pixelated picture. The game plays smoothly but everything is pixelated. I tried cleaning it but I didnt see any improvement on the pixelation during gameplay. The start up screen is always clear and clean. Do you think the Black Main Chip is damaged or do you think I just need to change the Green Circuit Board?

  • @Disthron
    @Disthron Před 5 lety

    Towards the end you solder a wire from one side of the paper boy cart to the opposite side of the chip, wouldn't that cause cross talk amongst the data? I mean the front connection and the back connection are supposed to link to different pins on the chip right? Wouldn't that mean the pin connected to the back edge connector is getting the data from the front edge connector?

  • @ItIsNot1984
    @ItIsNot1984 Před 5 lety +1

    Instead of adding solder to those joints, you should have melted them and allowed them to resolidify. That is reflow. All you did was add solder on top which wouldn't do any good if there was a leg poorly soldered into the board - you'd just be putting more solder on top of a bad joint. I think maybe the pop sound you heard when heating the chip at the end could have been the ceramic inside fracturing? not sure.

    When I ordered a genesis 2 years ago, It sort of would read games some of time. So I went to clean it as a obvious first fix, there were wads of cat or dog hair stuck in the cart slot, like an impressive amount of hair in it. Worked perfectly fine after that.

    Trace repair on older carts is pretty easy once you get the hang of it. Retro Repairs does it a lot.

    a tip for those weird screws:
    ive seen people melt plastic ballpoint pens and push them into the holes and then let the cool down and harden in the right shape...

    Great video Vince, you should however use a little bit of flux to make your life easier.

    Would clear nail varnish work as a protector for the wear and tear?

    Well done with the first cart, I was surprised you got it working, looked like nearly all the traces were cut.
    A couple of things: You can get a meter with capacitance test, and there are very cheap component testers on ebay too. Worth having one - when you test a cap it should be within 20% of the uF value. The voltage is only relevant if you're replacing one - you need the same rating or higher.
    Those extra holes :) They exist probably because the PCB is generic and can take a larger size ROM. When you moved it up, the power supply pins ended up connected to the wrong pins, very bad!

    You worked out how to find pin #1 on the ROM. If you look at the board it has a 1 beside the hole it corresponds with. Pin #1 on the ROM is also located on the end which has a notch cut out of it.
