i think i fried something in my yamaha vss-30 while poking around for possible bends. i'm fairly new to bending but i've had no problems bending any of my other keyboards or drum machines. guess i didn't realize i could permanently damage an instrument by simply connecting two points, stupid me.
at this point, i can't get any sounds pressing the keys. i'm pretty sure it still turns on because the speaker makes a noise when i turn the power on and off. Also the speaker hums and hums louder as i raise the volume. i checked around with a multimeter and there is power flowing through different parts, but i'm not proficient enough with this type of thing to figure out where the problem might be. i've tried batteries and power supply and plugging the line out into a speaker.
also, the big chip on the board has started to get really hot after a few minutes of power. i'm not sure if the chip itself is bad or something else is bad and is making the chip overheat. or maybe it always got hot and i just never noticed.
i just don't want to have to buy another one of these keyboards. thanks.
