CPU S7-1513F-1PN all leds are off, ehternet non function, only display function

Hi all,

I have this CPU S7-1513F-1PN es7513-1FL01-0AB0.

When i connect to 24V DC, the display power on but all leds are off.

I try to connect with ethernet for upgrade firmware or reset the CPU but ethernet not function and leds not blink.

This CPU works good for two month, but is out of garancy because is old.

What can i do to solve this problem ? Is possible that the firmware is block ?The problem could be the internal power supply?

Thanks 

Hello,

you are right that ist could be the internal power supply.

Please look fort the diagnosis at the display.
Can you see there any error?
