Casio Collectors

yea my problem with repair guys is the ones i've called act like its somethin that they have no knowledge on being that its music gear, i keep gettin told "i dont know anything about keyboards" or "thats not somethin i do" ????? i thought electronics repair was electronics repair all the same, guess not though......so if my problem ISNT the transistor, would a multi meter have to be used to test every little capacitor resistor etc, do i need to test this while plugged in even though im gettin no power, and if so, do i neet a static mat?, and i guess my last question would be, what if its the power plug on the unit?, if thats the problem would it be burnt up or anything like that, any way to test that?....oh also what would be the best soldering iron to grab........i think i have a 15 watt one layin around, but last time i used it it didnt seem to get hot enough, used it to re-solder rca cables on a turntable, and it was a nightmare, so maybe i have a
 P.O.S solder gun...............anyway thanks for the help so far.....really dont wanna throw my ht away :(

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.
