This keyboard keeps having little problems, but luckily they've all been manageable without catastrophic failure. But I've had it for a long time and if I'm able to extend it's life I'm going to try at least.

I'm not a professional electronics repair person. But I have experience in basic troubleshooting and principles. You don't have to have formal training to repair electronics. You just have to be curious, but careful. Some experience is nice and if you're an absolute beginner you may mess up here or there, but if you can get through it you will learn.

Happy repairing!
