Need help: DSD-440 with unresponsive formatter/control board

[Julian Wolfe]

Both green LEDs are on.  They're ALL on.





This is a failure of the DC Power Up/Down circuit - See page 3-10 + 3-53/54 in June 83 

Service Manual. If the components in this circuit (capacitor) are out of spec, then this may be the cause. 

 

Congrats on picking it up. I was tempted to bid for it as well, but I already filled had my boat anchor quota. 

 

Is the Green LED on?
