NUC5PPYB bios update no HDMI

[gianarb]

Hello

I have 10 NUC5PPTYB. All of them were working (BIOS started on HDMI).

I updated the BIOS for two of them. I didn't write down the BIOS version that they where running but the other boards are all running versions: 

PYVSWCEL.86A.0055.2016.0812.1130

I updated them to https://downloadcenter.intel.com/download/29571/BIOS-Update-PYBSWCEL-86A-?product=87740

The logs said that the procedure went fine but after a reboot, there is no HDMI signal anymore.

The fan works but the power led after a first blue signal it switches off. If I hold the power button until the power led becomes red the light stays on with blue color.

I tried various recovery process, I tried to clear the CMOS and I tried to boot the board without the BIOS Jumper but nothing shows up on video. 

They both stopped working.
