    *Links / Corrections / Useful Info*
    1) The small IC above the black ribbon connector (315-5638) is a 6 button multiplexor (this is logical if you consider it has a 6 button joypad built in!)
    2) The tiny 10 pin chip near the regulator I think is a AN8015SH (step down / step up DC to DC converter) - guessing (as I said) for use with the invertor board.
    Confirmed both of the above after uploading the video, using the Console5 wiki!
    a) Regards the RAM connections"going through" the resistor arrays - I think they are more likely pullups rather than connections passing through them. Just didn't think about it at the time.
    b) When using hot air to remove components, it is best to remove the PCB from the case / shell etc. You could melt the plastic!
    c) 4th method to remove SMD capacitors (comment from Haggledesperado) is to use two soldering irons, one in each hand. Heat up both the pads and once the solder is melted, use the irons to lift the cap off the board. As safe as hot air, perhaps less risk of heat affecting anything nearby.
    d) 5th method to remove SMD capacitors is to twist the top of the can - higher risk. If corrosion is present I would guess a 70%+ chance of a pad being lifted. If the pads are OK, 20% chance of pad being lifted. Obviously there are other factors that increase or lower risk with any of these techniques. eg. PCB manufacture quality, size of pads vs size of capacitor fitted (larger caps have larger leads etc).

I watched a recent video where someone printed (laser) to a special transfer film and then using water slid the image off onto the device, added some heat (not too high to melt) and the image transfered to the surface.

    Hey GadgetUK.
    Thanks for the video, i really enjoyed this 3 part series. Just wanted to give you a little tip i used on my Wonderswan regarding the glass lens. I had the same problem you had with the glass screen beeing slighty bigger, but i used a metal nail file to very easily file a bit of the glass screen and it fitted perfectly after.
    Keep up the good work!

    Great video and work - couple of interesting things I thought whilst watching it - firstly I noticed the board marked 'Venus' in a number of places, which corresponds to Sega's 'planet' codenames - the Game Gear was code named 'Mercury', the 32x was 'Mars', we all know about the Saturn. Jupiter, Neptune and Pluto were unreleased prototypes.
    Secondly, I wondered if the Z80 which is used for sound on the MD was used to help run Master System games, and apparently this is the case. A clever cost saving way to implement backwards compatibility, using a chip that is not solely dedicated to the task.
    Thirdly, I wondered what the options are for doing a region mod. I remember adding a 50/60hz switch to my Nomad which was very fiddly and quite ugly. I think there is a way to add a switchless mod but I'm not sure. Perhaps the Everdrive is a better solution although I think there are a small handful of PAL games that wouldn't work properly at 60hz.
    And finally, try running Virtua Racing on the Nomad, it looks absolutely gorgeous on the small screen.

    • @GadgetUK164
      @GadgetUK164  5 років тому +1

      Yes, I forgot to mention the Venus designation for its codename =D And yes, Z80 for sound, but main CPU in Master System mode. They are easy-ish to region switch. The problem as far as I understand can be with composite, as the timing is incorrect for the colour burst signal, and the CPU not exact the correct speed when the jumper set to 50Hz. You can get a switchless mod that has the PAL crystal onboard too. I might do a mod myself with a PIC chip at some point. Will try out Virtual Racer on there later =D

    Nice video. Felt your pain at the screen part. It is always the same. Do you leave it at 99% happy and have to look at it every time or do you go back and tackle Sod's Law one more time to get 100% (and then wish you'd just left it alone as one issue leads to another 🤣).

    • @spidermcgavenport8767
      @spidermcgavenport8767 5 років тому +1

      The reason why I love the Sega Nomad was while my military service I played mine for year's. It's a portable genesis which was better than the Gba which I couldn't see unless having proper lighting, but while on ship and a 6 month deployment this was the only gaming device needed, while the Dreamcast was exquisite it needed a t.v. Which was constantly being used by other crew members. So to fix this circumstance I bought a VGA box so I could use PC monitors while playing a variety of gaming consoles but the most important was the VGA box for the dreamcast that I found at a pawn shop was was ultimately allowed me to use my dreamcast even while others monopolized the tv's available.

    A better LCD for the Nomad might be PD035VX2, which is 640x480. It should give less interpolation blur. The one you have there is 320x240. $63 with a driver board (Aliexpress) is a lot more expensive though.

  • @ItsMeWaggle

    The lines in the screen you're talking about are caused by an effect called dot crawl, visible normally only in composite video signals, which is very visible on places where two very distinct colors meet, or where black and white meet. en.wikipedia.org/wiki/Dot_crawl
    The 4th paragraph in that article says older consoles and computers use a non-standard burst phase, which explains why the screenshot provided in that article is not exactly what is happening to the signal generated by the Genesis, but it's pretty much what is happening in the signal.

    • @GadgetUK164
      @GadgetUK164  5 років тому +1

      The particular issue I beleive wasn't dot crawl! I've seen that before though on other composite videos I've done. In this particular instance its a diagonal wave that goes across the screen from one corner to another, which I've seen before on other systems - often where a switched PSU is used, or there's some ground plane issue. With dot crawl it tends to be super evident on certain colours - eg. red etc. I showed a good example of that up close on the Saturn RGB cable video I did.
      It could be that the screen is not locking onto the chroma signal very well. Because now I think about it has similar appearance to that BBC Model B where I showed the difference there between composite and RGB. But maybe that is what dot crawl is - I need to refresh myself lol.

    PS, those Sega power supplies all have leaky capacitors inside them, too. I forget the proper size - but I wanna say 16v 3000uf, but I'm unable to find that just now, and don't feel like ripping into my power supplies to confirm. But they're all leaking by now - I've fixed about a dozen of them and not a one was good, and they do eventually short out the power supply. They've got a diode inside of them that just gets covered in electrolytic goo.

    If that lens is as tight as it looked and took that much force to squeeze in there, I'd be worried about the plastic developing cracks over time as that stress the assembly is now under has to go somewhere and it's unlikely the glass will yield first. I'd probably have just returned those lenses as defective.

  • @missionpassed4584
    @missionpassed4584 5 років тому +3

    I saw a guy having trouble fitting a mirror once then he started sanding the edge of the mirror manually with fine sand paper until it fitted, may have worked on the shitty glass screens hope this helps in some way for future issues. I remember my brother bought a sony xperia z1 off a mate a few years ago cheap as it had a broken screen, it was so thin and had to be glued in place it took me 3 costly attempts to fit it and it broke after being used a couple of time each time, before i gave up and bought a chassis with screen fitted, only to find at the end of swapping absolutely every little part of the phone over, that the screen was bulging and coming loose due to clips on the inside that held a small wire in place, i then out of desperation took it apart removed the clips and used superglue and a pin to get between the thin glass and bezel, the glue ruin the screen, i could have cried.

    • @GadgetUK164
      @GadgetUK164  5 років тому +1

      That's a really good idea, but I think I would prefer to try and sand the screen protector edges as someone else pointed out though - the reason being is widening the Nomad edge is irreversible vs altering the actual protector!

    Hello! Why not use SMD Ceramic capacitors instead of new electrolytic ones?

    • @GadgetUK164
      @GadgetUK164  3 роки тому +1

      Ceramic capacitors don't filter the same way wet type aluminium caps do, and they have totally different characteristcs regards how they behave at different temperatures, and they can be affected by vibration and sound (they can oscillate). You could fit them, and not notice too much of a difference, but they are not doing exactly the same job. Ceramic caps also tend to short when they fail.

    I don't suppose you know if a similar composite screen would fit in a GameGear? Whilst the mcwill screens are great, I really don't want to spend that much. My GameGear still works but has numerous stuck pixels, so could do with a new screen ideally

    • @GadgetUK164
      @GadgetUK164  5 років тому +1

      I don't think there's a composite signal on the board - if there is you could use the same screen as did probably.

    • @GadgetUK164
      @GadgetUK164  4 роки тому +1

      Honestly cannot remember much about how the board is laid out regards the speaker circuit. You need to follow the connection from the speaker to find the audio amp circuit. It could be a bad trace around there, corrosion damage etc. Possibly the transistor needs replacing. The fact the headphone audio is OK means the audio amp IC is fine.

      I would start by running the diagnostic / test BIOS via an Everdrive or SD2SNES. That will give you a clue as to whether there's a problem with the audio chips and related RAM. It could be a fault with one of those.

    • @GadgetUK164
      @GadgetUK164  5 років тому

      =D I think the opposite is required actually! You need to cool the shell (plastic and metal contracts with cold, but will expand with heat. The heat technique can help free up rusted / stuck screws / bolts though, the idea being that the outside of the thing you are screwing into comes loose a bit from the expansion and contraction. I suspect these screens will be easier to fit when the platic is colder.

    Great mini-series there, Gadget. I'm worried about the stress that screen glass will be under, though. A bit of flexing the case with over exuberent playing might be enough to crack it. I also noticed that the cap you replaced at 20:37 is 16v, not 6v. Is that why it's a bit too big for the connections?
