Hi there, just found this forum and first post....
I have a Casiotone MT-68 that won't power on. I'm using a 7.5v mains power supply which works fine on another Casio SA21 keyboard that I have. When I use it to power the SA 21 the led on the power supply stays on as I would expect. But when I use it to try and power the MT-68 then the PSU led goes off when I switch the MT-68 on. I am assuming the MT-68 is centre negative which is the case with the SA21 but I have tried the PSU in centre negative and positive positions but the MT-68 stays dead and the power on led on the MT-68 never comes on.
I haven't tried to power it using batteries as I don't have any D cells. I have opened it up and poked around with a multimeter and the power switch seems to be registering 7.5v so it looks like power is getting in to the unit but I get a bit lost after that.
Can i ask if anyone has any experience with the MT-68 and is you could offer any advice on getting this keyboard up and running?
Many thanks for any help
