  1. hey adrian can i use ds0138 osiloscope with 2.4in. screen to test signals while reparing my old c64. i have experience in electronic repair and i want to by cheap osciloscope to practice little bit. i dont know signals so i need and appreciate your advice. john

  2. Great stuff, have to say I pointed at the Zener as soon as you noticed that short circuit C-E, great devices Zeners but always failing.

  3. 34:32 *deep sigh* alright heres the schematic (again!) lol sounds like youre sick of the back and forth at that point

  4. I have no idea why I am watching this. I have zero knowledge of this stuff but its still fascinating to watch.

  5. if you use hot air from the underside, with the board straight up and down, using a chip pliers on the socket you can get the sockets out no problem, I really dont like that you put hot air right on the chip, it could fry them.

  6. When you are de-soldering put the iron on and heat the connection then while vacuuming move it around the pin;
    circular motion with the pin in the hole of the iron. If done right many time s the IC or Socket will drop right out.

  7. your a very clever novice finding all those traces broken good work mate i love your fault finding method its technical not many people understand what oscilliscope readings mean ,sometimes.. bye

  8. Why is it that the SID always goes bad, i have a C64 sitting in a drawer with a bad SID chip but i refuse to pay $60 for a new one.. Anyone ever came up with a knockoff replacement chip?

  9. I notice that you use a custom Final Cart 3 with custom menu and programs. Do you sell this?

    1. I dont no, I traded something for that cart — and have since loaded up some of my own stuff onto it.

  10. for the loose sockets you hate so much: no need to desolder. pry the plastic frame of the socket up and youll find the spring pins still in place on the board. spread them out a bit for more spring action and then press the socket back down on them. thats it!

  11. I think theres a place in hell where slaves are forced to fix these pieces of hardware!!! The rould of Technicians…. 😀

  12. Im not buying the Im a novice schtick. Adrian you are a very good troubleshooter and very humble…

  13. I have a very same issue. My data line 3 is grounded at U10 pin 2 and 14 and 16 connected,all are grounded. Blank screen, dead test cartridge no help, no screen. I replaced U10 and U27 and PLA AND VIC CHIPS, NOTHING….NO CHANGE.? I also clipped the #1leg of U16 LIKE THIS VIDEO, BUT NO DICE. If i touch top leg crystal with oscilloscope screen turns to all white dots like it is the U31 oscillator broken ACCORDING TO THE PICTORAL SCREEN ISSUES WEBSITE. BUT EVERY CHIP ON BOARD HAS D3 DATA LINE 3 GROUNDED, I.E. PINS 15 ON ALL 3 ROM CHIPS, PINS 30 ON BOTH CIA, CPU, PLA, VIC, ETC…., ALL HAVE ONE PIN at D3 GROUNDED.? All dot clock and color clock signals are correct. Voltages correct. Replaced one Zenier diode 2.7 volt at U27 input, it was bad. And U10 AND 74LS08 AND 373 CHIPS ARE PIGGY BACKED. EVEN WITH U10 CHIP OUT NOTHING IN PLACE and pla, cia, cpu, vic, chips removed, still have one pin on every socket and soldered big chips at data line 3 which is grounded, pin2 , 14, 16 all connected and to ground at U10, SHOULD NOT BE TO GROUND, PIN 2 , 14 should free float. HOW DO I FIND THE GROUND? Open ground, right? The short, is it inside one chip? Tested all chips, Margolis book. Logic probe and oscilloscope. ?…….the data lines on board never been touched, pristine virgin pcb, original owner.

    1. Now, I found that the hex inverter chiphas 6 pins which are reversed. Pins 1&2 are low and high and should be high and low, i/o. Also, 4 other pins not matching the high low as Margolis book explains, 1983. Maybe that could be source to ground on D3 lines, hopefully.? The Reset chip, but the CLOCK MGHRTZ IS CORRECT AND RESETTING NOT STUCK IN RESET.

    2. I have also tested all of the pulled socketed chips, U10, and the new 74LS08, 74LS373 chips I repladed, with a continuity test from the D3, data line 3, pin on each chip to ground pin on that chip and there was no continuity nor continuity between any two pins of the chips, so those are all good, so it is either a trace short or a soldered in place chip imternal short. Good video, helps, but not complete, thanks. I could not do any better. Kool shirt.

    3. Replaced U10 4164 dRAM TWICE, TWO DIFFERENT CHIPS. NO DICE. AND STILL EVEN WTH ALL SOCKETED CHIPS REMOVED, ALL D3 DATA LINE 3 PINS, ONE AT EACH CHIP ARE GROUNDED, TO GROUND , SHIELD. YES, PINS 2 & 14 SHOULD BE CONNECTED, DATA IN DATA OUT , BUT NOT TO PIN 16 GROUND OR SHIELD on the U10, WHICH IS THE DATA 3 dRAM CHIP #3. EVERY CHIP ON BOARD ALMOST HAS ONE PIN, THE D3 PIN, CONNECTED TO GROUND, SO THAT IS A SHORT. IS THE SHORT IN A CHIP? HOW DO I FIND THE SHORT, IVE PULLED ALL SOCKETED CHIPS IT IS STILL GROUNDED AT THE SAME PINS ON THE EMPTY SOCKETS AND EVERY WHERE ELSE, ONE PIN ONLY PER CHIP, D3 PIN. I cannot clip all those single D3 pins on every chip, can I ? Those are $45 chips, im not clipping them. Thanks.

  14. So you make so much noise about bad repairs etc, and still youre not ever wear gloves and touch everything bare hands…

    Mr Adrian, I don’t feel so good…

  16. Not bad at all for someone not savy with electronics.
    The logic you apply to troubleshooting is quite OK.
    The proof is with the result!

  17. Hi there
    Would you know if an APPLE / MacIntosh PERFORMA 205CD has any value ?I have one but I cant even test if it powers up… I have the CRT but no cable..
    THANKS

  18. Just wondering if FPGA replacements for all of the custom chips are available then maybe that might be the way to go or go the whole hog and scan the schematic into the ALTERA FPGA compiler and hopefully it spits out a file to program a SPARTAN FPGA and let you built a new C64 with a lot less chips.

  19. Hello Sir, I wanted to say thank you and great video! You are definitely NOT a novice in my eyes. What I saw you do in the video referencing schematics, going specificlly to the tracers on the board and the chipsets on a 38 year old computer, that is definitely not novice. Great job and I learned that it can defintely take a while to troubleshoot these things, especially someone who may not have all the equipment that you used.

  20. Hi there ! You did a marvellous job repairing this board. Your methodology of fault finding and fixing is very good.
    I also wanted to say that it’s always a good idea to use good quality chip sockets.
    I’ve encountered also many issues with bad sockets at work.
    Nice and crisp video too, very informative !

  21. I have two solid years of electronics training and over 30 years of experience, and know very little about the C-64 inter workings, I own two, and used to program them in Commodore basic. You did an awesome job of troubleshooting the board, and had real tenacity in diagnosing each and every problem. You have better patience than I do. Very well done repair and video. I learned a lot about the C-64 watching your video. Thanks!!

  22. Hi nice repair, i noticed i have the same desolder gun what is the right temperature setting? Also what is the name of the donkey kong game you use for testing? Great work keep it up there. Claus from Sweden http://www.mtxworld.dk

  23. I bought a damage Commodore 64 7 years ago and I fixied with my son, now he is a computer engineer.

    tgis video bring back memories.

    Best Regards.

  24. Ok, I’m a newb to c64 with what may be a dumb question. I just scored my first one along with a 1541 disk drive. I am understandably really freaking excited, though I am expecting to do some repairs on it because it’s probably been living in somebody’s attic/basement for many years. I’m not afraid of that. But here is my question: I opened it and found a 8500r instead of the 6510 I was expecting to see. Was this normal in this generation of board when they were new? I have read that the 8500 and 6510 are interchangeable. I was just wondering if this was common to find? I thought these were in newer 64c models. It’s an assy no. 250425, and I don’t see any evidence at all of any rework on the board. I will need to come up with a solution to connect it to a monitor, so I can’t test that it is alive. Thanks for your time, and awesome videos!!! My zen happy place is to have your videos playing while I’m working late on servers that can’t be touched during the day

  25. Maybee this RAM is broken….changes it directly.
    This socket is a piece of crap…..works 4 hours to revive the connection and test if it could be anything else

  26. Thumbs up and subscribe! With your Rigol do you ever come up against any bandwidth limits where a higher bandwidth would help (assuming youve done the 50 to 100 update)?

  27. I know you annotated that you meant in the static bag but I couldnt stop laughing at in the main board is a broken c64 main board.

  28. Well, its nice to see that C64 finally fixed. I had given up, and after watching that video, im sure id have never gotten it fixed on my own, so thanks! I have a Zener diode to fix that cassette port from a (would you believe) worse parts board. Also another SID chip (I might have put the flaky one i had in there because I didnt want to risk a good one in that board). Just need to track down a PLA chip (or PLAnkton).

    1. @LeftoverBeefcake The maker of PLAnkton says thank you for the vote of confidence!! -)

    2. @Tyicus Yeah, Adrian is the Louis Rossman of de-oxy….

      Seems that Louis Rossman and Adrian uses similar amounts of flux and de-oxy 🙂

    3. @LeftoverBeefcake Your correct, I ran into lots of problem PLA chips and a few CIA chips too. Thanks for the information!

  29. 1:22 Why you dont notice the ripped trace when you point a chip near it?
    5:29 Ehh now you do 🙂

  30. Hi Adrian! Thanks for your videos. I have a commodore 64 that all appear to be ok, it give image , but when i try to type something, no keys works. I replaced the U1 and the same issue.. cursor blinks ok but no keyboard any ideas? Thank!

  31. I have the same desoldering gun and have little to no trouble desoldering chips. Adrian, do you do the circular wiggle and hold the gun tip straight onto the board? Also do yourself a favour and buy some solder wick. I’m a convert and it works great for cleanup.

  32. Youre probably better than most professional electronics repair engineers, and when it comes to the C64 you probably know more than the original designers of the board, so I wouldnt exactly call you a novice.

    1. Its from an o-ring pick set. There is a link in the description. (Or there should be.)

  33. Hey Adrian I just finished resolving all issues with my C64 when i figured its time to finally swap out the last power cap the small 100uf 16v. So I swap it out and then the system doesnt turn on, so i pull the new cap and test the old working at 89uf, and the new 49uf. I put the old working cap back in and now the system is dead test 1 flash so i replaced u12 and same 1 flash. I am going to check logic chips, etc cause its all in sockets due to an AC power surge across this board from a power supply failure. I swapped out the 257s, 7406 and 566 and then moved memory all over still 1 flash.

    Question is, would you have expected the lower Uf of the cap could cause this kind of damage and i assume this is why you test your caps and resistors before dropping them onto your electronics.. Unfortunately this is another painful lesson and is upsetting as I bought 30-40 of these caps from JameCo and i tested a handful and all are out of spec as mentioned, some as low as 39uF for a 20% 100uf 25V cap. This board has also been down and under fix for some time and I just resolved it today… swapped cap and now dead again. 🙁 SAD DAY IN C64 LAND…

    OK i figured it out. I was seeing an issue with the LM566 U20 and U8 the 7406 not getting their proper reset signals.. ping 9 on u20 and ping 12 on u8 they were static so i reseated the kernel rom U4 and now it comes back online. i have to see if the kernel rom was just not getting good contact, see if its one of the sockets i installed and if so triple check the traces again on the bottom but alas, it turns on and now the active low and active high signals are normal again and i get a boot up. Back to Candyland for me…

  34. 29:13 – Hot air, underneath the PCB where the socket is. Wait until hot, lift socket. Easy.

  35. Thanks, this was interesting. Learned a lot and now feel much better to try to fix my own C64. 👍🏻

  36. My score is fixed fully thank you derickwalker454 on IG yiu good I will give you good recommendations always

  37. Try to do continuity tests from the DIPs legs, this way you test the sockets and traces, so the complete trace

  38. A technique Ive learnt for desoldering dead chip, and the MUST be dead… get a dremel with a cutting wheel(or snips) and just cut the chip off.. once off you can heat individual pins and pull them without risk of damaging the tracks.. 10,000 times faster and safer

  39. Nice job!. I have the utmost respect for your patience and perseverance Adrian, you inspire me to try and repair some of my old C64s as well! Keep up with making these excellent videos!

  40. Great job. As a amateur noob. You have convinced me not to get into c64 testoration. It requires far more knowledge and skill than I have. I’ve done a few obvious capacitor replacements where they are blown. But have not the equipment or skill to work ok this. Good job

  41. Hi Adrian, from Montrealer to Montrealer, I have a Commodore 64 bread bin (1 of 3) that is acting weirdly when I try to use the super snapshot 5 NTSC with my 1541 U II + or my EasyFlash, those cartridge works quite well on my 64c. Other cartridge work’s mostly well on the bin 64. It also sometime refuses to boot. Dc voltage is at 4.86 when everything is loaded. My inch is that it is too low. I am using a brand new PS. Any idea? Thanks.

  42. Hm, I have a method that is pretty different to yours with desoldering throughhole. Its pretty much flux on it, put some new solder on it, suck it out and use hot air until it falls out. I do most of the time newer stuff like smartphone jacks, so its pretty delicate compared to yours, but some jacks have a throughhole ground and Im no stranger to normal stuff too. But with the SMD Crap and how fast you can break something, I had to learn how to be gentle 🙂

  43. @Adrians Digital Basement
    Nothing surprising if you remove chips while logic board is cold… To remove whatever always you have preheat the board first up to 80-120 degree C and then you can remove whatever. I always do like so plus in case of ics use low melt alloy like chip quick, clean pads with desoldering station and never get rip off pads, but anyway I agree with you that ics should be mounted in sockets… Pads gets rip off because of massive thermal shock caused by not preheated PCB or too high temperature on the tip, eventually when apply heat on pad too long, eventually crappy quality of PCB but in this case you can also avoid ripping off pads with low temperature soldering and board preheat… I understand – not everyone has to have budget to spend on preheater, but everyone has at home hairdryer for sure -I does it in this way and works very well…

  44. I loved how in-depth you went for all the little details, and the throughout process of trying everything out. Excellent!

  45. no more than one leg of a transistor should be grounded I have been trained and am not a novice

  46. 0:20 does lifting it and lowering it 4 inches make it work better like a Polaroid?

    I had to poke fun 😛

  47. Thanks for this video. The more problems you had and were able to fix the more I learned. Im actually wanting to build my C64 from scratch sometime in the near future and had help from others where to buy parts. Even was given options of upgraded replacement chips that I would like to consider. My currently C64 had a bad VIC II chip and was able to diagnose and replace without any previous experience (I suck had soldering but was able to clean up my mess). Im doing some researching right now before I consider a complete build. Thanks for sharing this video. 🙂

  48. Oh man, Im finally starting to feel more confident to start approaching circuit troubleshooting using schematics now, especially since now youve shown results of many mistakes caused by previous repair attempts. Going for round-hole sockets is a nice tip too!
