trouble shooting - Yamaha PSR3000
by Reyguel Nious
(Columbus,Ohio USA)
My PSR3000 keyboard has a crazy tendency to flash continually after I turn it on. When I DO turn it on, it powers up to the final screen. Suddenly the LCD screen will start flashing the Yamaha logo and gives no sound or functional operation. I've checked the cold solder joint where the adapter plugs in and I've checked the adapter itself. Could it be a bad computer chip, outdated "firmware" , or something that makes it power out like that? Thanks, Reyguel Nious
