Korg Forums

My Korg Triton LE has worked fine for a number of years. Recently, after turning it on and playing it for a while, the sound suddenly completely drops out. I do not believe it has anything to do with the audio output jacks or the sound system.

We have a lot of electronics around the area where the keyboard is located. I wondered if it were possible that some kind of electromagnetic interference could cause this. Or maybe it's just a component going bad.

Does anyone have any suggestions?

lowell,

My experience with sub-voltage power (at least down to ~100 volts) is that if there is a problem it will manifest as a reboot... you'll get the korg logo and things will come up again eventually. [Surprisingly, my tritons have kept chugging in situations where guitar pedalboard units throw in the towel because of lack'o'power.] That can be fixed with a voltage regulator or uninterrupted power supply that uses batteries or slow discharge capacitors to make up the difference.

From the symptom you describe, tho', I'm thinking it's either the power supply in the board, a half popped chip or maybe a cold solder point on one of the interior boards... either way, something that doesn't show up until the unit has been on for some time, i.e., building up internal heat. The heat expansion could be enough to break a contact that's fine when the board is relatively cool.

This is something I'd take to a shop -- deciding factors being the age of the unit ("several years"), whether you've gigged it (possible road shock, use in low voltage situations, bar grunge build-up, etc.) and the "hell, I dunno, it just stops" nature of the fault.

[If you've noticed exactly how "it stops" manifests that'd be helpful here and especially in describing the problem when you take it to the shop: when does it happen? how long after power-up? how long before coming back? does cycling power (off/on) bring it back up? lights out or still on? spontaneous reboot? Anything you notice can help in the diagnostics.]
