Hammer did you get rid of the Tyros?

Mikey,
I sold both of my Tyros 3 keyboards and bought a Tyros 4 which I still have.

Hi Tony,
that was me.
I took it to a technician to try & get it fixed. Didn't think it would be worth the cost. Told me the board was corroded.
[quote=Tony Hughes] Deane could you take the SD2 apart and take some photos, didn’t someone say the PCB on theirs was corroded.

Tony

Rikki,

Deane is not coming back to us, I asked him where he bought it from, he sgould be able to send it back, hell it must be just out of warranty if that, if Deane's SD2 has a corroded PCB then Ketron are not washing PCB off after soldering, this might be a common fault, unless Deane takes the top off he will never ever know, it will just sit there or be thrown in the trash can (bin). Rikki what did you do with your SD2.

Can't Deane post it off the Ketron.

Tony

Hi Tony,
I still have mine sitting in a cupboard. I'm only going on what I was told. I don't think I was the only one who's sd2 failed after that particular update , though.
Mine was well & truly out of warranty at the time. I just took it to the same guy that was recommended by the music store to get my out of warranty korg repaired. He fixed that ok, so can't see why he'd be wrong about his diagnosis on the sd2? There's basically nothing to them, so all of the value must be in the board itself. Cheaper to just replace it, by the time you spend money on getting someone to repair it. They charge $50 to $100 just to look at over here.

A failed update sounds more like corruption than corrosion.

I still have one SD2 and sold one. It is fine but I never tried to update it.

The Ketron SD2 update procedure is not secured, and 90% of the users who tried it killed their SD2.

I think there is a bug on the Ketron update software, who just send the update file as SYSEX to the SD2

Then the SD2 writes the received SYSEX message into it's memory

I think there is maybe one MIDI packet who is lost during the Update, so the SD2 internal software is corrupted.

This memory is soldiered directely into the SD2 mainboard, so you have to unsolider it, and replace it (or reprogram it with an external programmer?)

The soldier is very fine, so you have to be a very good soldier man.

It's crazy !!!

KETRON, if you read this, as a software developper who knows good Ketron products, I am ok to write for you a SD2 UPDATER software FOR FREE who will not kill the SD2.
Just send me the specs by email

Now there's an offer for you.

I find this hard to believe but not entirely hard to believe, why can’t AJ tell you this or his he frightened of tell you, if its true what Dan said. Deane, does frank know anything about the SD2. It’s looking more and more like the trash can every day. You could put it under the back wheel of the car and reverse over it, when you get tyre right on top of it , rock the car backwards and forwards, that will surely kill it stone dead. It’s the final solution.

Tony

As of today I still am not able to leave a voice mail for Ted at CMC and my emails have gone unanswered. I have a new one on order with Frank.
