Well David, the first thing you're going to need to know, is how to solder and de-solder.  Without those skills you're not going to be able to fix much of anything.  If you're serious about this, it's going to require that you invest a considerable amount of time, and some money, to get started.  I'd recommend getting yourself a good soldering iron and a multi-meter to begin with.  There are lots of online resources for learning to solder - YouTube is a good one.

I can help you locate the transistor that was fried on mine - and if that's also the problem with yours, it'll require that you replace it with a new transistor (de-solder and solder skills).  If that's NOT your problem, then it's going to be more involved to find out what is.

I hate to say it, but you might be better off taking it to a repair person...

>I recently fixed mine - had a cooked transistor.  Pretty easy to spot as the area around it was all black.  I don't think this keyboard has a voltage regulator inside like most equipment.  I checked the AC adapter I used and it was putting out like 13.5V.  I think that's what killed it.

>>i have a casio ht 6000 here that until last month was working perfect, and now it just will not power on with an AC or batteries, and the only thing i can think of that i might have done is plugged it in with the wrong AC power adapter when i was re-arranging my set up , as i use several universal ones set to different polarities and volts. i dont even know where to start with this, i've called several local electronics repair guys (yea right) so maybe someone here can point me in the right direction as i dont even know how to go about testing this unit, or what to test for that matter....any help would be appreciated ,.....i really dont wanna throw this gem away.

>>also, i have taken apart the casing to see if anything was burnt or loose around the power plug in the back, looks fine to me......anyway, thanks in advance!!!
