I can't say thank you enough. This video was insanely helpful. I've started repairing consoles as a hobby and this video was very informative. The whole channel is a godsend.
In the same boat here, just starting fixing 8 bit home computers, found this video and it's soooooo informative, thanks so much.
Dude I just found this channel. And I like it. Thanks for sharing your hard earned skills for people like us who are interested in electronics and didn't get to go to school for it. I have fixed several items since watching videos from people just like you. Thank you very much. I don't need the skill for a job. However, it is a hobby. And I'm helping people out for free when I am successful. Because it is all knowledge gained each time. I have a friend at work I will be picking up 4 consoles from Thursday to try and get them going for him. No guarantees, however what does he have to lose.
Your videos are immense resource! Thanks for all your work!
thanks
Very good video!!!! Nice job! I just happen to be testing a model 2 genesis like you have in the vid!!! Thank you!
This video is solid buddy, very well done!
Great video. Really enjoyed it mate.
fantastic video, heaps helpful and super interesting
Wow, learned so much from this vid. Thank you!
Fascinating! Looking forward to more of your videos!
+Bryan Bowen Thanks. What did you like about it? I'm tempted to do more videos like this, but only if people want to see it. I was going to do one on identifying components, soldering and general repair.
+Global Garage it's all pretty new to me. Just recently watched your 7 Genesis repair videos and it really got me interested in learning this stuff. I'd love to be able to make my own repairs. I've torn apart and cleaned a bunch of my systems but the electronics are something I haven't touched. So your videos have been a great introduction for me, and I'd love to learn more about soldering specifically, as well as identifying components and learning what their purposes are.
Definitely interesting, looking forward to more videos like this
Thanks
just made a trip down to jaycar and bought a multi meter and assorted fitting wires etc.Watched this video and played along with a mega drive im trying to diagnose .Awesome video for a noob like me.Kepp them coming man perhaps some super nintendo mods?
Thanks mate. Yep Super Nintendo is next. Im working on one right now which will be ready in a few days.
Great video. I use my multimeter alot in repairing the retro consoles, it's a truly invaluable tool. I graduated in 1998 from high school, so I'm just behind you on the "old train". Funny how time flies, isn't it? LOL I think my tastes are still stuck in the 90s as far as gaming and music goes. Thanks for another great video, Darren!
+Elizabeth L. I'm sure that video was a bit too basic for you, but thanks for the comments and feedback. The 90s really was an amazing decade! I'm writing some blogs on my other website which you may enjoy. I'm soon to publish a few on what it was like to be young in those days, my memories of gaming and of course the elusive video shop with a Street Fighter II cabinet in the corner just begging to extract the $1 from my pocket. www.retrosales.com.au/blogs/retro-gaming-news
+Global Garage How awesome! I'll definitely check it out. I'm not sure if it's a nostalgia factor or not; but, I've found that the older games were more difficult and had a more immersive story than alot of the games now. But, I'm also a huge "grunge" music lover and I hate most modern music because I find it devoid of any meaning. Not that bands like Nirvana, Silverchair, Sound garden etc always produced songs that had meaning, but damn they were amazing. LOL
+Elizabeth L. Older games certainly had more playability. They were simple, yet addictive and damn hard. I don't mind modern games at all, but I'm drawn back to the good old days of SEGA and Nintendo. Music.. there's plenty of good modern music! Come on. Get yourself Spotify and listen to some playlists that other people have put together. It's the best way to discover new music. PS. Radiohead were the best of the 90s. :P
+Global Garage I definitely feel the same on games. I do enjoy new games, especially strategy games. But the older ones always call me back to them. Shining Force I and II are still in my top 5 games.
LOL I'm just not into the newer music for the most part. The last "new" band I really enjoyed was Mumford and Sons and Kings of Leon. I'm pretty stuck in my tastes as far as music goes.
Great video! I'm getting continuity between my ground and positive on my mega drive 2. Does this suggest a short somewhere?
Hi I am trying to fix my Japanese Sega Saturn because whenever I turn it on. The screen remains black. The consoles turns on and it seems to work when I pop a game in. But neither image nor sound will come out. I read from forums that it may have something to do with the capacitors but I am not sure.
Very instructive video as usual.
If I could request one video, is how to recognize components, especially the small surface ones on newer technologies.
Those really are a pain, they all look the same to me.
+adilator That's a really good topic! Thank you for the suggestion. I'm certainly not an expert on that anymore as I haven't worked in electronics for years, but I can have a go. The newer ones do all look the same but there are little tricks to help identify them. What were you hoping to repair? I mean what type of equipment?
Old consoles are really simple, but on handhelds, laptops and slightly modern consoles, even the fuses look like surface mounted resistors and capacitors. I have encountered this issue while trying to fix my 3DS which has no headphones audio and a laptop boards that was shorted.
adilator Yep I'd have to agree. The newer stuff and small stuff is quite difficult compared to the old consoles. Did you fix your 3DS?
+Global Garage I have no sound when I plug the headphones on my 3ds. the speakers go mute, so that mean the headphones are detected, but there's no sound coming out of the headphones. I opened it to check the headphones connector and check if all the small ribon cables are plugged and everything seems fine. I resoldiered the headphones connector and now when I plug the headphones, I can hear a very faint sound from them.
I think the heat from the soldier probably slightly revived a bad capacitor or resistor?
+adilator Hmm usually the capacitors cause this type of issue. Replace them and see how it goes. Sounds quite fiddly though! Good luck
is there a way to mod the master system controller to be more reliable?
Thanks for the tutorial how to use multimeter on retro consoles. I have been trying to figure out what is wrong with my Mega drive 1(european). I tried the 2 voltage regulators and the middle pin says same voltage as the input on both. Do i need to replace the regulators or is there a another solution? I used some multi voltage adapter, 12V 1000mA setting. It worked fine half a hour and then it just shutted off and stayed that way.
Edit: I checked the adabtor with the multimeter and the 12V setting gave me 17V. Does this mean i brick'd my mega drive?
Hey Elmer, it sounds like you've got some power issues there! That power supply is not correct, so don't use it. You need to find a 9V DC adapter which outputs at least 1.2Amps but more is fine such as 2A. Try a new power supply and test again.
I have a N64 that when it's turned on, after a few seconds it's led starts blinking and the power supply stops working (The PSU is fine, tested on other working N64s), so I can't check voltages on the board because some part of it it's shorted/malfunctioning and turning off the PSU. What could I do to check it? I thought about using a different PSU that would not turn off, but that could potentially ruin the system further.
I'm trying to figure out what's wrong with my Saturn, and got myself a multimeter. However, you state a lot of warnings not to test the current. Is it safe to test it after it's stepped down to AC after the power supply board? I want to test chips/capacitors on the board.
Hi, I purchased a pt multi- meter to test the f1 & f2 fuses on my nintendo ds but in what setting should I turn the knob to? Thx.
Rick Gomez Continuity, as if the fuse is blown there won’t be a path and there will be no continuity beep. You could also use DC volts and measure with the console on. One probe on ground and the other on each side of the fuse. If it’s blown, one side will have voltage and the other side nothing. If both sides are the same then the fuse is ok
Hi, thanks I'm having a hard time choosing a multimeter the range specifically (minimum and maximum range) for this use case: what Fluke model will be able to measure all the capacitors, resistors, voltage, current for retro home video game consoles and current video game consoles, PC & Mac power supplies, desktop and laptop motherboards, GPUs, PC CRTs and LCDs, Wacom drawing tablet (w/ lots of SMD capacitors, resistors and other tiny SMDs?
A non-Fluke model and brand that's affordable, low cost but decent that'll repair the things above (essentially electronics found in houses) recommendation would be cool too.
I ask coz' my current digital multimeter can't measure some small SMD capacitors and some big electrolytic ones, I'd like my next multimeter to be the one to measure the things above, if possible.
Thank you. God bless, Rev. 21:4
Excellent video, it's helping me a lot; thanks! I have a question, though: I have a busted MD model 1, and I'm suspecting the VCCs. I tested them, and they're reading out 7v input/4v output; is this normal, or should they still show 12v/5v even though there's two of them?
Do you mean the voltage regulartors like 7805? Yes the should have an input voltage pretty much matching your power supply, so 9V-10V DC. The centre pin should be ground and the output pun needs to be a very steady 5V DC. Something like 4.97V DC output is alsofine, so just use a digitial multimeter and check. If it's too low then the regulators could need replacing.
Global Garage thanks, that's what I was suspecting initially; however, further testing suggests me that something might be wrong with the AC adapter itself, I tested the leads on the power plug and they're reading 6v instead of the suggested 9v. I'll have to test the jack directly later today, but it seems to be the most likely culprit at this point (and then I'll test the VCCs again, it's possible that both might need a fixup). Thanks again, much appreciated :)
BeastOfSoda yep 6v is not enough
Global Garage hi! I fixed it, turns out it really was the AC adapter that crapped out; sometimes, the right solution really is the simplest one, which I realized only after going all the way and testing the innards of the console. At least thanks to you I am now more confident in doing electronics work, and my next stop is the 50/60 mod; thank you so much for your insight and the critically useful videos, I really appreciate it a lot! (P.S.: subscribed! :D )
You're welcome
Very informative , but hfe is just the current gain of a transistor ,not really useful for most common testing purposes ,to test a transistor to find if it is good just treat it like two diodes that are hooked back to back , put your meter on ohms scale place one lead on the base and one lead on the emitter then reverse the leads you will have a resistance reading in one direction but not in the other ,do the same for base to collector this will have similar results then place the leads on collector to emitter and you should not have anything in either direction that is if the transistor is good and just like a diode if it is shorted or blown the resistance reading would indicate this
it is easier than it sounds if you do it a couple of times and it doesn't matter if you are testing a PNP or NPN bipolar transistor you just want to know if it is good or bad no special type of meter needed
Anyway thanks for your time and thank you for the video
+MrBuck295 You are absolutely correct Sir! Yes I have tested transistors like that a few times, it's easy and works well. I was going to explain that in the video, but decided against it as I would have morphed into an explanation video on how the transistor worked and I thought that was getting too far off track. It's a idea for another video though.
+Global Garage A video about basic electronics and how some of the components work , sounds like a great idea
but what ever kind you post I`ll be sure to watch and enjoy
Thank you for tanking the time to make these videos
+MrBuck295 I'll brush up on my theory and make one soon. I have about 10 consoles in various states of disrepair that need some love, so I'll mix it up a bit and come back to this style soon.
your board was manufactured in January 13th 1995. google what happened in history
