I have a Toshiba TP50H15 with a power supply shutdown problem, The -18V
overcurrent is tripping the sutdown circuit (found some power supply
functional detail on the web) I cannot get any fruther without the
rest of the schematic. Can you provide any help?
Any clues or suggestions would be appreciated.

Thanks very much
