    yeah bad.

    tried my baku disassembly pick but was still way to awkward.

    You can get pen-like spudgers/spludgers that work quite well, some with bends or some that are just flat.

    So I fixed my faulting AES cartridge :leet:

    The problem turned out to be that the plastic that's meant to keep the two pcbs moderately tight had worn away to the point where they were not sitting flush (and was also pressing into the outer cause causing some of the chip feet to bend, lucky none of them caused any shorts)

    Once i erasederd and isopro'd the pcb pins twice over, then once I also added O-rings to the cart guts in the right places the game has worked since without error.

    \o/

    Repaired a dead SNES tonight.

    Had the dead unit (thank you goobers...) and a spare dead mobo up for grabs, no one was interested, finally got around to taking a good look at all the parts.

    one of the boards has a bad fuse and was previously region moded so the PPU2 chip has some lifted feet and other issues

    the other one i thought was badly corroded, I lifted the soldermask on the areas that looked bad and to my surprise almost all of it had good continuity. found a bad trace leading into the Encoder chip, repaired it, got sound and video, very happy.

    naturally its not for give away anylonger. :leet:


    edit:
    so that brings my working snes's count back up to 10.


    anyone got any advice on if or how to seal the solder mask back up. i dont want the exposed traces degrading over time.

    I'm thinking clear nail polish, know if anything else suitable? cheers

    The proper way to do it would be with something like crc plasticote 70. That is what I have on my workbench right now and it works well. It shows up under uv so you can see the coverage, and if you put a soldering iron to it it evaporates and lets you solder.

    awesome, will hunt down a can cheers!

    For restoration/refurbishment heres the short list:
    • isopro alchohol and/or crc contact cleaner
    • magic eraser
    • de-solvit or eucalyptus oil
    • lithium grease (for optical roms), carbon grease (other mechanical plastics - controller analog sticks, etc),
    • Staedtler pencil erasers
    • electric screw driver and gamebits.
    • precision tool set (for flat/phillips/torx heads),
    • mobile repair tool set (for tri heads, pick tools and angled spludgers)

    For doing actual electronic modding or repairs:
    • an antistatic surface mat or wrist strap (dont buy those bogus wireless dealys though)
    • maggi magnifying lamp or similar
    • about a 60w~ soldering iron, solder, desolder braid and a tube or syringe of flux
    • sand paper or dremil bits for removing solder mask
    • a half decent multimeter. (mines also a 330v tazer, just cos i could)
    • wire strippers(ie pk-3161)
    • several spools of varying wire gauge
    • hot glue gun
    • a heat gun

    you'd want various other stuff on hand also depending on what your working on:
    • heat shrink
    • sticky tape, masking tape, electrical tape or even mylar
    • pliers, tweezers, scissors
    • batteries / super glue / thermal paste
    • the usual additional cleaning stuff (cotton tips, tissue, , vinegar, multipurpose surface spray)

    for a decent amount of broad arcade/console repair knowledge, watch lukemorse1 on youtube.

    I left the foodsaver off the list but yeah :lol::lol:

    ----

    gonna get another fuse for my spare snes board that wasnt working. I had a shell for it originally but gave the shell to an ocau member who wanted an old console shell to run retrobright tests on.

    If i get it working, itd make for a handy backup or i could look at getting a simple replacement shell printed.

    Do you use desiccant or UV the shit out of it prior to storage?

    What kind of monitor are you going to run this on? Don't like the chances of a HDTV accepting 240p via component. If it's a CRT, why not get a scart monitor? Component is a slight downgrade from RGB.

    desiccant packs.

    I'm expecting a parcel soon which has 400 more desiccant packs.



    would you use UV for sterilization? couldnt it harm the box art.

    I use isopro for sterilizing the controllers/console shells, as for the box art i only give them a super gentle wipe down with a cloth and a tiny bit tap water if they have like gunk or shit built up on them

    thanks dude.

    also if i had done the pcb naked test you suggested, that would have worked and led me to fix it using orings also. :)

    Component YUV (or in analogue colour space, YPrPb) is mathematically identical to RGB.

    Other than a few chroma adjustments for white balance, there should be zero visible difference between YPrPb and RGB.

    As for the screen, I only do my retro gaming on CRT. I've got a number of 80cm CRT televisions with YPrYb inputs that I've wanted to mod for RGB for ages, but that process is non-trivial. This little kit might be a good alternative to getting better image quality out of my old consoles that are all already RGB modified.

    I've got a number of smaller RGB CRTs (some SCART TVs, and some Sony PVMs), but I'd like to run some stuff on a larger screen from time to time.

    Fair enough. If already rgb modded/do rgb by default, why not just get an rgb to component converter box? Then you could use it for all the rgb consoles on your larger CRT.

    Received a Epox 8KTA3+ today from ebay and on inspection have discovered this plus a few more bulging caps hopefully it hadn't done too much damage.
