  • Hi, in this video I attempt to fix a faulty NES purchased from eBay. It was sold as 'no power' can it be fixed?
    Merch is here!!!!! www.puddlt.com/my-mate-vince
    If you would like to support these videos, please click here / mymatevince
    If you have an interesting 'non returnable' item for a 'trying to fix' video then my PO box is:
    PO Box 2597

    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.

    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.

    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?

  • @GadgetUK164
    @GadgetUK164 2 ปีที่แล้ว +29

    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).

    • @Mymatevince
      @Mymatevince  2 ปีที่แล้ว +12

      Haha, nice one Chris. So that is a shame about the PPU, at least it is NOT married to the SRAM. It is strange how so many things went faulty. Maybe the fault cascaded from one chip to the next. Certainly not my best buy on eBay but on a positive I learnt a lot about this system. Hopefully the next one I come across will go smoother. Cheers for the info as always 👍👍

      Not just a nice MMV Patreon early access vid, but a great wealth of information from Chris as well. I'd gladly enjoy watching Vince swap Famicom components onto a NES board. I do agree the risk definitely needs to be considered when purchasing other failed consoles.
      Neither here nor there really, but what always amazes me is opening up a clone console and seeing a single COB (Chip on Board/Blob chip) replacing pretty much every IC in an old NES. [Insert any random "you're getting old" comment] 😂.

    @itsnouse-yourswillbeastill2562 2 ปีที่แล้ว +9

    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.

    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.

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.

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.

    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.

    Also, the moment you found it was a screw, and you couldn't work out where it was from, I instantly noticed that the cartridge tray is missing 3 screws :) 2 gold ones, identical to the case screws, and 1 long silver scerw.

      I don't understand why he tried to power it on with something rattling inside. He could have damaged more. Always open it u first and remove the rattle before it shorts something and blow up another chip.

    Just FYI They sell a new ppu replacement that works mostly okay. It has some compatibility issues with certain games. They used them in clone consoles.
    I came across those while troubleshooting a similar issue where I had an nes that worked perfectly except it would send a troubling amount of voltage to the ppu.

    Cutting traces on a vintage board seems like sacrilege. Oh and I desperately wanted you to test a few of those discrete components. Diodes go short circuit and resistors go open. Good you found the chip pinouts. How about Checking all the obvious voltages across all chips first. Good fun though.

  • @rfmerrill

    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.

    Almost same thing happened to me on a SNES I got off of eBay. Turned out the controller connection on the motherboard was bad probably due to a faulty voltage regulator. I only knew about the problem when I plugged it to the tv and it was working perfectly after replacing the voltage regulator and the fuse. It was reading cartridges but not led or control functionality until I replace the connector on the motherboard.

    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.

    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.

    I don't know what all that original scratching was about, rarely see constructive examples of that heh. Before you started I thought check the Lock-Out chip and disable it, it's a wonderful self indulgent piracy solution that often locks out legitimate cartridges lol. Shame about the PPU, always a drag when a bespoke IC dies but good fusion solution. ;)
