Impossible Oberheim Matrix-6 Repair (Part 1)

This Matrix-6 was raided for parts, and whoever worked on it last really butchered it. Will I be able to bring it back to life?

One of my favourite synths. A very nice sounding poly.

This was cool. Just bought a Matrix 6 with no output. Seller says it may be D/A converter. I’m new to repair so this is super helpful!

[@kayslabs]

I know the eBay listing and was watching it. What did you end up picking it up for? I'm not sure if the D/A converter would necessarily be bad, but something to check. Anyway, thanks for watching...part 2 is coming up soon!

A better way to repair this kind of damage is to get AWG 30 Kynar wire and a stripper for it. Don't try to solder to very fine traces. Solder to pins of IC's, vias, and leads of components. It will be much more reliable. Also, the service manual for the M6 is available on the web and would show the connections to the EPROM. No need to figure it out from another board.

hi i got a question i hope u can help me because i really don't know how to start , everything works except for Yes Button

[@kayslabs]

Sounds like you need to replace the Yes button switch. It's fairly easy to do. You will need to buy a TACT SWITCH 12*12MM 7.3MM THROUGH HOLE SPST from a place like Tayda or Mouser.

I am trying to replace the battery that is on the board you took out. But you do not show the removal.... Why? The info you give is nice but SHOW YOUR WORK.. At 8:20 your cut away is madding.

[@kayslabs]

First of all I'm not a professional, I don't get paid for any of this, and no...I don't make any money whatsoever from. the ads that Google is imposing on all of us. I don't always catch everything on video unfortunately, but I also assume that certain things will be fairly simple for people to figure out. Replacing the battery is pretty simple, just unsolder the old one (carefully...don't strip or pull the traces off), then get yourself an inexpensive 2032-style battery holder for the 3.3V flat battery that you can buy just about anywhere. There is a positive that is clearly marked on the circuit board, you can see it clearly at the 28:38 mark. On those battery holders, the positive is at the top, so just colder the adapter in place of the old battery and make sure you insert the new battery in the correct direction. All in all it's pretty straightforward, but if you have other more complicated issues I'll try to help if I can. Alternatively you can also request for a video with more detailed explanation, although when I can get around to doing it depends on my schedule etc.

[@StevenBardo]

@@kayslabs First of all ? You making money on the video is irrelevant. I do not need help on buying a battery or diagnosing the issue and no did I ask you about the need to buy at battery where it is or what type or how much they are or even about the clip. My comment was based on the fact you did not show removal of the circuit board. [ the 3 screws on the midi i/o was the part I missed]. That was the part that I needed to see. My apologies if I have bruised your ego. Assume? What that every person that watches your video is a certified repair tech and have worked on the Matrix 6? There will be no request.

[@Slipstreamaudio]

@StevenBardo you could have removed your battery in the time you have spent being circular argumentative.

[@StevenBardo]

@@Slipstreamaudio. " circular argumentative." ??? Thank your for your useless comment. I had already removed the board and replaced the battery. I acknowledged Keylabs help, "The info you give is nice" in my original post. Done before I replied to him. Have a nice day. Show your work.

Normally I like trolls. You’re an annoying troll.
