TI-58 fault - repairable?
Hi

Any insights into whether this TI-58 is repairable appreciated. Completely dead with battery supply, no display. 

Some main readings on images from downloaded service manual. Voltages much lower than spec.

The flat round component on internal PSU board hot to the touch after less than a minute powered up and can smell warm resin. Internal image link courtesy of datamath.org.

Thanks for any insight!

David
