    Heya, I'm not sure if others have said anything,but I do quite like it when you show the actual work/soldering being done. I've noticed the latest vids have alot of that cut out, would it be possible to keep more of that in?

    A note about that first chip in which the pins voltages seemed to be swapped: All chip with a 74HC part number are what is called glue logic chips. They allow the main chips to work seamlessly with each other. That particular chip (74HCU04A) is an inverter. The pins you were looking at will always be opposite logic levels to each other as one is the input and the other is the (inverted) output.

    If you plan to fix more of those old systems, best is to put those chips on a socket for easier parts testing

  • GadgetUK164 - Retro Gaming Repairs & Mods

    That warm fuzzy feeling when a Patreon early access Vince video appears =D That leg on the CIC chip, if that's not cut and lifted - it will reset the NES constantly (if there's no cart in the slot which is the correct region). Cutting and lifting that leg bypasses the region check, and it shouldnt reset all the time from that point then. The PPU is not married to the RAM. The SRAM types can just be different, but you can swap the RAM without issue. You can source spare RAM chips (equivalents), but the PPU - the only place you will get one is another PAL NES. The NTSC NES has a different PPU and CPU. The alternative is to buy a cheap Famicom and swap the CPU and PPU, crystal and a few other components to get it running as an NSTC NES - but that's a lot of messing around, and if you buy a faulty Famicom you don't know if the PPU and CPU are going to be OK (and both are required if converting to NTSC).

      @GGigabiteM Since the NES runs on AC I don't think reverse polarity DC could hurt anything, the input runs through a rectifier anyway. The 7805 voltage regulator can also apparently take an input of up to 35 V, which is massively more than the regular power supply provides. So I'd look for likely causes elsewhere. We know some quite ham-fisted person messed with this console and we don't know if that was before or after it failed. They definitely did some impressive board damage!
      I wonder what happens when the voltage regulator loses its ground connection - would that possibly cause the output to go haywire? We definitely know the ground connection was severed by those scratches and I think thats the regulator IC.

    • GGigabiteM
      GGigabiteM 4 months ago +1

      @My Mate VINCE With so many faults and the blown LED, I would hazard a guess that someone plugged in the wrong power adapter, or the power adapter they used had a fault. Either too high of a voltage, or DC with backwards polarity.
      Sega Genesis consoles are killed in the same manner, people using AC supplies or the wrong polarity DC plug that blows up the linear voltage regulators. Genesis consoles use outside positive barrel jacks, while the majority of today's power bricks are inside positive. Also the wrong voltage, the genesis needs 7.5-9v and people try 12-24v supplies that again blow up the linear regulators.

    • Ray Herring
      Ray Herring 4 months ago

      There's no reason to cut the CIC pin, there is a no-cut method which works far better since some games will just actively refuse to work if the pin isn't present.

  • It's No Use - Yours will be a stillborn

    When you take out any chip to make a swap its always a good idea to put in sockets since it minimize the risk of tearing off the solderpads and traces (the chips feet/pins can also break off from stress) . It also saves you time from not having to re solder things on and off obviously. Its a habit anyone should get into when dealing with chips that aren't being manufactured anymore (getting rarer) & should be treated with care. Ultimately think of it as an nice gesture to the next person who will be repairing / tinkering with the console next time. While Vince did it towards the end I still think he could've saved himself some heartache by doing it right from very start instead.

      I too have been using this method. Especially with Buy it Now items. If I see something Im willing to pay the Buy it Now price I will first watch it in hopes the seller will send me an offer. Hey, it works! Its usually only a discount in the 5-10% range but I figure thats like getting free or reduced shipping! Of course if its something I REALLY want I just buy it.

    The service manual or a schematic would make fault finding a lot easier but I'm guessing they don't make it so easy to find them. A pity as it would cut the time spent fault finding considerably. Note to self - don't bother trying to fix a faulty NES as life is far too short. 😁

    Sometimes, instead of removing a chip, like here to check the Reset state, it's easier to just cut the copper trace, to make measures.

    Just in case you don't know already but I have that same desolder station and the fan is really loud. Very annoying. It is a 5cm 12v fan being fed with 18v so it's working flat out. I replaced mine with an 18v one off eBay and it's much quieter. Just plugs straight in to a black box on the back panel of the station. Might help you keep the noise down if you're trying to film while using it.

    Whether or not the unit needs an RF shield has nothing to do with whether you're using the RF output or not. The shield is there to block radio frequency interference in and out of the main part of the unit, and also the RF modulator is going to be active even if you don't use its output.
    That being said, a lot of Japanese-made products from this era just slapped complete overkill shielding on the export versions, I suppose because they did not think it was worth it to keep failing their certification just to save money on parts. I've never heard of anyone having trouble with a mega drive or NES after removing the shield, in the unit itself or in nearby electronics. I would keep the shield on the actual RF modulator, though, as that is more likely to become an unintentional radiator.

    • rfmerrill

      @Acumenium They can be, but usually that'd be clear and in many cases they don't.

    • Acumenium

      Aren't the RF shields also primitive forms of cooling/heatsinks (if they make board/chip contact)?

  • MizuhoChan
    MizuhoChan 4 months ago +12

    So there are a few options for the PPU. You can either get a replacement clone PPU, which would be a 6528P (P being the PAL version), or you could get both an NTSC CPU/PPU which are easier to find, I had to buy some to repair a couple Famicoms and replace the oscillator for whatever NTSC is, I forget. I had a look where I bought my OEM IC's, but there weren't any 2C07's sadly.
    Of course you could get both the NTSC replacements too, which would be cheaper, which are 6527 and 6528, made by UMC. You can also get compatible SRAM from a variety of locations, you can buy some from aliexpress, you can get it from games sometimes or I have some, since that was also damaged on the Famicom I repaired, if you'd like.
    Other than that, nicely done on the CIC chip diagnosis, I have never seen one of those go bad, though I did know you can use any from a game, so that's nice you had a spare handy.

    • Acumenium

      @Dan I would say clone chips are still a good idea if you're intent on using original (or as close to it) hardware and carts. If very, very few carts don't work, a flash cart might be a viable alternative, or just emulate it on something if that's viable for you as well.
      I didn't know clone chips weren't exact though. I wonder if this causes issues with SNES repro games since many of them use custom chips for sound effects or graphics?

      @Dan I've never heard of this or looked into it much but I'm not surprised. It's hard to perfectly replicate a chip. I wonder if flash carts avoid that problem though?

    • Dan
      Dan 3 months ago

      I was of the understanding that the reproduction CPU and PPU chips have compatibility issues among other oddball flaws with other games. Sure would be nice to have perfect reproductions of the original ICs for this and other consoles....

      @MizuhoChan I remember seeing in a forum someone removing the CIC chip completely and replacing it with some bridges... Since the system doesn't need it to work (famicoms don't have a CIC chip) it works a treat!!

    if its rattling, ALWAYS open first it might be a loose screw, that can mess things up even more.
    also, the rf shield has nothing to do with the rf output, its to shield the chips from rf interference.

    • iWhacko
      iWhacko 4 months ago

      @Simon Quigley either way, it was total nonsense of him to say he didn't need the rf-shield because he wasn't going to use the rf-output.

    • Simon Quigley
      Simon Quigley 4 months ago

      The RF shield is there as an FCC requirement to block the interference that the device may generate, which would affect other devices.

    You can find some decent schematics for the NES online. They may not exactly match the unit you have but it may be close enough to give you a clue. I usually go to the console5 wiki for game console schematics first because they collect as many as they can.
    The actual NES schematics however are third-party and are drawn in a somewhat confusing and unorthodox way. I often find myself referring instead to the Famicom schematic which is direct from Nintendo and is a lot more normal. Note however that aside from using the same CPU and PPU, many other things are different about the Famicom (it has no lockout chip, the cartridge and expansion connectors are completely different, it has hard-wired controllers with different signals, the io buffers are arranged differently) so that's of somewhat limited use.
    One more thing to be careful about is that there are a few *different* RF/power units even with the same NES mainboard, so you have to make sure you're referring to the right one.

  • Michael Jensen

    No joke, for the first half of the video I was yelling at the TV, "check the LED".
    The second half of the video, I was all, "check the CIC chip".
    I know it was more than that, but having no access to the hardware, I'm surprised that I got those right.
    Honestly tho, I would just do the CIC mod, to remove the chip, because it's a reason that sometimes legit cartridges fail to work (I think you need to ground that pin 4 also?). It's basically DRM from the 80s, and it causes just as much harm, sometimes making good cartridges not work.
    Edit: I agree it's not the VRAM, you'd still get video, it would just be corrupt.
    Re: wram -- I think a lot of cartridges like SMB3 have wram on them. But also you can use a modern replacement with more address pins and just tie the high address lines low. (It's a waste, but whatever, it will work, you just need to wire the chip up by hand.)

    I still remember back in the day I had both a Sega Master System and a(n) NES. Both came with 9V bricks with the same barrel jack. One day I accidentally plugged in the SMS using the NES adapter. Result, non-working SMS. That's when I learned the NES brick output was 9VAC whereas the SMS brick was 9VDC. Had I been handy with electronics I might have opened it up and had a look for myself, but I ended up sending it off somewhere for repair. I later blew the NES RF port by using the TG16 RF modulator that was attached to the TV, being lazy and all. I had to buy an external modulator from Radio Shack and plug it in to the composite inputs.

    The reset pins of the two big chips are both inputs. What made you think the big chips are faulty if they get the wrong voltage on their input? The part that produces the voltage for these inputs was much more likely to have a problem.

    The biggest problem these have is the lack of friction when inserting the cartridge. This means the contacts get dirty. But never use a cheap replacement connector from ebay. I replaced mine and it was worse. The original one is fine just needs a good clean.

    I have been watching and enjoying you videos for year now Vince. On this one I was a bit surprised, I thought you had more knowledge of how to troubleshoot a system like this or basically any old computer of console. I don't mean this in a negative way, so hope you don't take me wrong.
    I have a few tips for next time, this is how I do this, and is a general way I learned from doing repairs. 1. check if power is going to the board, you can do this easiest by just taking a logic chip (74...) and measure between bottom left and top right, this should be 5v. Then check the reset, most cpu's have active low, and if stuck of toggling then find the source, I have never seen a chip pulling this low, so it's in the part that generates this signal (a schematic would help here). Then check clock signal, no clock no activity... If all good, check for activity on data and address lines, if nothing then check cpu. If cpu is running then there should at least be something on the screen, and this will lead you to further troubleshooting, like working ram, video ram, or anything like that. Hope it helps for next repair, you have come a long way from your first repair video's and have learned so much. I enjoyed watching you videos and see your knowledge grow.

    Ahh, yes, you brought out the old one whereby you've repaired everything, especially that adaptor, with pliers and your telecoms experience 😜.
    That said, let's see how the non-yellowed one fares here.
    29:37 Hehehehehehe
    At least you've found the faults here (on the bright side) Vince :)

    What you paid for the NES may be a little over what you wanted to pay, but it has good parts in it that can be useful to fix other one, and i feel it is worth it just for the spanking clean case.

    time code 8:06 to the right of the crack in the board, and down, are a couple disturbed looking solder joints on two through hole components. Seems you just swapped the board in the end for your repair... Maybe this was the problem after all? Thanks for your vids, I'm learning stuff here!

    I've been restoring NES consoles for about 6 years now and I've never come across ones where any of the components were married to each other. I've been able to swap any and all parts. That being said, I've only worked on NTSC consoles but I don't see why it would be any different between regions. I don't think you can swap PAL and NTSC specific parts though. That would be too easy.

    • GGigabiteM
      GGigabiteM 4 months ago +1

      None of the components in an NES are married to each other, at least within regions. Vince just confused himself because of the different package variations of SRAMs.
      Common DIP SRAMs back then came in either 7.62mm or 15.24mm widths, which is what you see between the two boards. If you look at the PCB around the smaller SRAM chips, you'll see a second row of holes in the board, the NES was designed to accept either. Nintendo did this so they could have more options for sourcing SRAM chips in case of supply issues. They were selling millions of these consoles and needed multiple sources for things like SRAMs.
      Other game consoles did the same. Several revisions of the Sega Megadrive/Genesis had multiple pads for the SRAM chips as well.

    if you need ram, you can also look at og red/white famicoms. Many are mega yellowed and/or cracked, are RF only and have attached controllers. With a bit of search you can get some in JUNK status aka untested for decently cheap.
    They are also useful for PPU/CPU change, but only for NTSC consoles, PAL consoles use a totally different CPU/PPU pair.

    Apologies for commenting only a bit into the video but once the screws are out the cartridge slot connector just slides off the main board. Just have to make sure you've got it aligned well when you reinstall it or you'll have trouble getting games to work. The original NES cart connector is notoriously unreliable--it's designed to be close to zero insertion force, which has the advantage that it does not wear down the cartridge contacts as much as typical edge connectors, but the disadvantage that it also doesn't clean the contacts either. The original NES cleaning kit does a good job of cleaning the cartridge connector, but people have also found success just chucking the whole connector in boiling water (find someone's instructions I've never done it myself).
    Also you appear to be missing some screws. There are quite a few screws holding the main board in normally.
    Also the confusing voltage at the beginning is because it takes an AC input. The ground of the unit is connected to the negative out of the bridge rectifier, not either of the legs of the input jack.

    at 8:04 below of where the board is scratched and cracked there are two cold solder joints, pausing the video at the time I marked, you can see them clear as day to the right of the tweezers and it's bugging me that you missed that.

    You could use the baking soda and super glue trick to fix that chip in the case.

    Hired Gun 4 months ago +1

    quick hint , buy a supply of cheap single side turn pin sockets and socket parts like these, the heat and removal and resolderong can cause damage to IC's, traces. or VIA's, then it makes chip swaps like these low impact

    Wondering if something killed it? Maybe a lightning strike or someone used the wrong adaptor? The rattle in mine was snail pellets, lol. Thankfully it wasn’t a series of faults, just someone cutting the IRQ line and reconnecting it. They mustn’t have realised they also cut the next line which stopped it doing anything. A second wire brought it back to life. I was thinking of the small chip early on as I’d done a fair bit of research while fixing mine. I didn’t cut pin 4 although I was tempted.

    • Simon Quigley

      Certainly seems like an over voltage issue, which damaged the chips and blew the LED.
