What should I do?
Thank you for helping me.

Hi,

The machine is completely dead? The touch screen does not show a progress bar? You cannot hear anything at initialization?

It is possible to have a defective power supply.

Have you disconnected/reconnected the ESS board (that one where all the cables are connected)?

Hello Nothing appears on the screen. I even changed the power supply. I also disconnected and reconnected the ess card several times.

It is possible to have a bad ESS PWB. The machine can enter in Dowload Mode?

[Calixte_01]

Non, je n'ai pas accès au mode téléchargement.

To acces Download Mode press and hold Power Saver button while power up the machine until the Download mode appear on the screen (if).

[Calixte_01]

No I can not get acces to  The Download mode

In this case I suspect the HDD on the ESS PWB or even the ESS PWB.
