Dreambox 900 has 2 identical boots . In first boot it verifies the motherboard/hardware and in 2nd boot it operates the enigma . Now it should be clear to you why its saying in putty " 2nd boot fail". Its not a hardware issue its just due to its corrupt enigma.

. Remove all sat/hdmi cables and then try to boot
. Remove front panel and power on the box , Connect hdmi cable and see if it show something over LED tv .
. Try usb boot to recover box .
