Good Morning All:
Got a 784A where the PSU is bad (this model: )
one of the capacitors has leaked and may be exploded to the point where the fiber glass weaving of the PCB is swollen and exposed.
It may be the +5V @22A supply.
Since these are large PCB traces, not to many are destroyed, I may attempt to repair the area, having the schematic would help.
Thanks
