Korg Forums

hi all,

recently, i was in the states and purchased an EMX-1. I do not know a lot about electronics etc. So when i got home, (ireland) i decided to plug it in and give it a go, untill after i plugged it in, i realized the volatge was different in america. So, i got a transformer, which didn't work so i thought the power suply may be blown. I ordered a new power suply and it came today. I plugged it in and the screen on the EMX just went orange, it didn't say ''Korg electribe'' and none of the LED's on the buttons came up.

So does this mean that i have blown the actual machine and i have to send it in to get repaired?

Any help would be seriously appriciated,
thanks

I'm so sorry for you, but send the EMX to assistance is the only way.

The mainboard fuse has blown, its a very small surface mounted fuse on the mainboard of the tribe, look at this thread:

or this picture, which is a lot clearer to see the fuse and assembly:

you can short it with wire, replace with fuse wire, or get a new fuse. Some people will object to shorting it, but my friend did that and his tribe has been good for years. As long as you never plug it back into the wrong supply again, then your really in trouble.

If your not confident with soldering or its still under warranty then get it repaired using Korg support:

thanks!
but, I do not think it is the fuse. According to korg.
What I am angry about is that, korg UK were completely useless when i rang them. I understand they dont have the part for EMX-1SD but i don't think they should have released the product without making a lot of spares.
oh well!

If you purchase a KORG product in another country, then your national KORG distributor will not support you, because you did not buy it there - they have not received any money from you. For support you would have to contact KORG in the country that you bought the product from.

It does definitely sound like the blown fuse problem, but you'll either need to get it to a keyboard tech/electronic engineer, or attempt to repair it yourself.

ok, thanks for the help!
i really appriciate it.

Everything you described is the exact symptoms of the on-board fuse blowing. Backlight on, no screen etc.

A few people have come on previously and have been told that "this is not the problem" by Korg, when it is the problem, maybe because they want you to fork out to send the machine for repair.

Good luck!

Yeah i wasn't sure if it was the fuse or not, because i thought if the fuse was blown then no power at all would get to the machine no?

But yeah i'm sure you are right. I got a box to send it away, but before i do that i may try and repair it myself, i cant live without it for four months!
thanks!

also, the fuse is very tight, and i am not 100% sure on how to get it out?

Power does reach the machine, the onboard fuse just protects the synth processors, but the back-light is connected to power input seperate.

You can solder fuse wire to each end, or melt the solder and remove the fuse. If you havent done soldering before, i would print out the tutorial (or the picture i posted) and take it to someone who has a soldering iron and knows how to do it, or a repair shop who can.
Or practice a bit of soldering first.
