Did I Really Just Fry my Casio SK-1?!?!
« on: November 19, 2017, 07:03:02 AM »

Hi Benders,

Admittedly I'm a total noob...I picked up a Casio SK-1 today on Craigslist and was having some of the most creative fun I've had in years. It didn't come with a power adaptor and I mistakenly plugged in a 12v adaptor with reverse polarity. The power light on the keyboard still turns ON (even while the button is set to "off") but none of the buttons/keys produce any sound.

I can't believe I did this to something I was having so much fun with and just picked up. FML. Is it ruined?? Is there a fuse I can replace?? Any advice is greatly appreciated.

Its going to be a dodgy transistor in the voltage regulation circuit. I'd guess T1, T2 or T3

You can find the service manual with a parts list at
i am not paid to listen to this drivel, you are a terminal fool
