So Ive been working on repairing a korg wavestation ex. Ive posted a couple times here already. But now I am legitimately stuck. The keyboard seems dead - When I power it on, only the back light of the screen comes on. No text, no audio output, no other sign of life. I tried all outputs, and even using another keyboard with midi out to try to control the wavestation.
What I already did
- I replaced the screen. I followed instructions, and have the exact same issue with the new screen as I did with the old.
- Took it right apart (not my first time with this keyboard), looked for immediate problems. I checked the components, and they for the most part, they pass the visual inspection.
* there are some resistors that are heavily corroded/damaged. I metered them and they give the value that they are supposed to be. I do have new ones coming in, though.
What else can I do? Just the screen back light coming on, can that be just a power issue?
Id love to get this going. Its a sentimental item for me.
