thanks but it's not E8 because it "Eb" .... could be E6? I don't find other pages that you attached to me ... so perhaps it's broken the 2 LEDs in the seven digits display? It's too strange ... or I'm definitely unlucky!
The error code definitely looks like EA Eb. The number "6" looks a little different than "b" on the seven segment display. See picture below for reference.
EA and Eb/EB can mean several different things for example:
EA : DDR3 training failed EA : Boot Loader start of loading the system file
Eb :: Boot Loader prior to entering the boot manipulation menu
To really know what is happening to the controller, open a support case so a TSE can access the serial connection to investigate the issue from the controller shell. Serial access on E-Series is only for Support use so a support case is your best option.
