Trying to FIX a BROKEN SEGA SATURN from eBay

Hi, here we have a Sega Saturn with no power purchased from eBay. Will it be the internal power supply? Will it be the output capacitors? Or will it be something on the mainboard which has shorted out? Let's find out.

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.

Fascinating chip the TOP220 and I had a read of the datasheet with the thought of using something like this in a future design and like a lot of TO220-3 packaged devices one of the pins is connected to the 'Tab' (the metal back) and this is no different and its connected to the SOURCE and it is stressed that this connection should be as solid and as short as possible for all the normal reasons and to stop EMI. This made me think that yours was flapping around in the wind, I dont know if it desoldered itself due to heat or the fact the connection was dodgy made it overheat. This also was the reason you had no heatsink compound on it as this is an important connection and must be electrically sound, this is stressed as it is the high voltage return path so personally I would have not put heatsink compound on there. I haven't read the application notes thoroughly but should the unit fail again I thought it you would like to know...cheers.

[@Mymatevince]

Interesting, I thought maybe cost cutting caused the lack of thermal paste. Hmmmm maybe I should remove it then and try and reinforce the heatsink to the board. My thermal paste is nonconductive as well so there is probably zero connection to the metal of the heatsink itself from the back of the TOP220 chip. Are you ok if I pin this comment? so others can see it. Don't want viewers putting on thermal paste if it is not needed and likely lead to early failure. Thanks Andy 👌👍

[@TrimeshSZ]

Assuming it's the same version of that Voltek PSU I have (likely, since mine is also 220V, although the console is the HK version) then the RC network that needs the low-impedance connection is in front of the chip and directly connected to the center pin and not the tab. The tab is also connected to the same trace, but all that end connects to is the input filter cap.

[@andymouse]

@@Mymatevince No problem, there's an outside chance I'm wrong but I don't think so....cheers.

[@andymouse]

@@TrimeshSZ As I say I have a datasheet not the Sega Console, how these devices are used is not necessarily "to code" The Tab is connected to the heatsink which is soldered down the trace you talk about may be a 'Sense'...cheers.

[@danielsauriol]

Definitely a nice and easy repair which is always very satisfying! But not as easy as what happened to me no later than last week. I spotted that the neighbor two houses down has put a fire resistant safe at the curb. The door is open but because it is "locked open", it is not possible to close the door without knowing the 3-digit combination. While taking it home, I realized it was fire resistant because its weighs was around 30kg/50lbs Once on the bench (i.e. kitchen table), I unscrewed the inside cover that was concealing the lock mecanism. All I had to do was to slowly spin the dial until the slot on each disc lined up, taking note of the numbers along the way. Looked up the particular model and it sells for $1500-2000CAD brand new. I sold it on Marketplace and made an easy $300 for 10 minutes of work!!! You don't run into these easy ones very often but when you do, it's such a good feeling! 🙂

Nice find. My personal best was at the recycling center some years ago. In my town i'm known for being "good at electronics".

[@leeartlee915]

One of the nice things about fixing up a broken console is that, since it probably hasn’t worked in years, there will actually be less wear and tear on the rest of the components. So that sketchy disc drive that’s in all Saturn’s will probably last longer.

[@Pholiage]

[@SidneyCritic]

When you remove a suspected shorted part it's best to check the pads to see if the circuit is still shorted, ie, another part has failed.

[@countzero1136]

Good advice, though my experience of working with these integrated 3-pin switching driver ICs tells me that they rarely take out other components when they fail, unlike many other more complex designs

Brilliant system along with the Dreamcast.

[@8bitnation419]

The best way to fix the no power issue in the Saturn, Dreamcast and even the PlayStation. Is to just get the Pico PSU mod which is a board that allows for you to use a universal power supply, usually 12v. It’s more power efficient, reliable and your console will run cooler since there is no psu inside. But for saving on costs you cant go wrong with this.

0:28 I use to repair car audio amplifiers over a decade ago, and would try to buy them non-working for a bargain, fix, then resell, but alas, could almost never get a bargain, and by the time you bought parts you were still into it second hand prices same as a fully working one, so was nearly a waste of time unless you wanted the amp. KZbin “fix it style videos” weren’t really a thing back then, at least that I recall, and I never thought anyone would watch someone attempt to repair something so I never even tried to make videos like that, but it is rather entertaining. I guess what I'm getting at is, to me it seems that it has always been hard to buy non working items for a bargain, well, at least anything decent / worth repairing. Of course you can snag some deals on occasion, but the stuff I was interested in, was rarely a bargain. As always, great video and enjoy watching! 7:58 I took an old pair of multi-meter leads, strip some insulation off and solder a large resistor a crossed the leads near the meter, and then insulate it. This way I could watch the voltage drop as I was discharging. I also think I may have used a spare meter for this and set it aside after I was done discharging so I didn't have to remove the probes on my main meter, or forget and try to read voltage with it. It's been years since I've worked on anything so memory is a bit vague, but did have some probes setup just for discharging as they are easy to hold / probe the capacitors with.

I think the 2" dome mids are the weak point so I've bought 4" (open-frame) cone mids to replace them, which I'll be putting in 0.09 cu ft chambers. I'm also thinking about changing the enclosures to 2.4 cu ft ported at 30Hz with 3" ports, but with plugs to seal them if/when wanted. Not that the bass is bad, but it could be better.

Too optimistically selected component, perhaps? Good fix at any rate, and glad the laser wasn't dead on this unit :)

I got the Saturn in UK launch. It came with a RGB scart cable as standard. Sega later on changed to RF unit/lead.

[@Silanda]

There was much complaining about the Scart lead IIRC. A lot of kids were using cheap TVs, and not all of them had Scart sockets. I know mine, which I'd been using since I got my C64, didn't. IMO both the Saturn and the Playstation didn't benefit too much from a sharper image anyway, at least for 3D games. The Saturn had the horrible mesh transparency, and the Playstation had dithering. Both were blended to an extent by lower quality methods of video output.

PWM stands for Pulse Width Modulation. A PWM Switch is basically a MOSFET with a driver and clock integrated so it keeps turning on and off at an specific frequency and the control pin changes how much percentage of the clock time it will be ON vs OFF.

[@Mymatevince]

Thanks Thomas, so it seems like a winning solution rather than having to use 2 components, a MOSFET and a separate driver chip. I don't remember seeing one of these PWM switches before (unless I just haven't seen them in this 3 legged package). Maybe with the heat generated in the MOSFET it is safer to use a separate chip????

[@thomasesr]

@@Mymatevince most switching power supplies uses a PWM signal to pulse DC current into a Transformer to generate voltage. In the old times they used to use various transistors and op-amps, than a 555 timer chip (basic transistor IC) and power transistors to do it, later they used separate IC and a power MOSFET. Later they integrated everything into a PWM switch, and nowadays is basically the same thing but with more internal circuitry to detect faults, voltages and be more efficient, such as over voltage protection, over temperature detection circuit etc.

@@thomasesr Thanks Thomas, in comparison a linear power supply seems like a joy to work on 😂👌

@@Mymatevince These integrated SMPS driver ICs are pretty reliable for the most part, though like anything they can fail from time to time, but unlike many more complex SMPS designs, when they do fail, they rarely take out anything else at the same time, making for a much easier (though sometimes more expensive) fix

Whenever a video is about a faulty electronic item in the UK my first guess is always moisture damage.

I had a PSU issue when I got mine form ebay. The board had snapped on the PSU and not connecting so I just used a ReSaturn to be safe. But hope you enjoy the console.

Nice fix I bought one working and had to replace the laser a week later. 🙃

I have my PAL Model 1 Sega Saturn connected with an RGB-Scart-Cable to my 20 year old Sony CRT TV.
