I NEED KORG ES50 'LAMBDA' REPAIR HELP

Postby froonbazhooley » Fri Jun 04, 2010 9:54 pm

I am about to be in possession of a Korg Lambda, and according to the owner it has some "tones that shouldn't be there, and some octave problems with certain keys." Specifically, some of the keys play an octave higher than they should. I do not know what he is getting at with the mentioning of tones though...

No one at all that I have contacted has been able to suggest anything. Is there anyone who can point me in the right direction?

Welcome to our world!

Likely one (or more) of the S10430 IC modules are dead.

Unless you've much experence with electronics, tools and soldering, I'd find a good tech.

Hm, I talked to an expert on ES50 repair, and that seems to be the case, I will have to probe it with the help of a better tech than myself to find out what is acting up.

Also, after cleaning it, taking the keys out, cleaning contacts etc. A few of the keys only play on the release of the key...? Does this mean I messed up one of the contacts one way or another, or is that another problem?

Ah, I fixed mostly everything now...

It's quite easy to fix Lambdas I have discovered if you are handy with a probe... The Korg Deltas have the same chips and dividers, so they are not TOO rare of a find, though they are pricey...
