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!!!
