Howdy ... I have an old keyboard that has been sitting in my attic for 16 years ... it worked when I put it up there but when I hooked up a power adapter to it, the other day I couldn't get any power ... I'm pretty sure the adapter works ... any thoughts on whether or not it can work again? Thank you for reading my post.

Did you try a set of fresh batteries in it without the adaptor?
If that doesn't work, it's probably shot. Probably the electrolytic capacitors inside corroded and started leaking. Short of a DIY job of locating and replacing the defective electrolytics it's probably landfill otherwise.

Thank you for responding to my post ... no I haven't tried batteries ... I will purchase some and see if that works ... if not I will take a look inside and see what is up. Even if I could replace the electrolytic ... there could be a problem finding the parts. It may well indeed be a candidate for the scrap heap.

Keep us posted on how it turns out.
Well sir ... I try some batteries and it works! 
After 16 years sitting in the attic ...it still works. At first I thought it was shot, but I still had the ac adapter plug hooked up. Once I removed that ... music! Just wanted to let you know that it's alive and kickin'

OK, if that's the case, then two things to check.
1) take a Voltmeter and check the output of the adapter. If the output is Zero volts then it's a no brainer to replace the adapter.
2) If the adapter checks out as good, then the problem is in the input circuit, probably a leaking electrolytic filter capacitor. Also something which is relatively easy to fix. The cap is probably isolated from the batteries by a diode which is why it worked when you unplugged the adapter and used batteries.
Anyway, tell this to a tech and he could probably replace the capacitor for under $40 if you want to go that route.

Hello I have a problem with my Casio LK-100 KB. It’s been working fine but I was playing it yesterday and it just cut off out of no where, so I just got up and changed the batteries and it still didn’t cut on I tried blowing it out just in case there was dust, I tried rearranging the batteries, but it still didn't work. I don’t have a cord for it just batteries. And just in case the batteries were dead ( the new ones) I put them in something else and it charged it up so I’m not sure what the problem is. It would mean a lot if you can help me.
