Alien1 00.00 on VFD

[mondeo]

Hello everybody,
Yesterday a friend called me having trouble with his box.We had loaded 2-3 months ago an HDMU image (i do not remember which) and the box had been working fine.The last 2-3 days it suddently started to work slow, with bad RCU response.
We decided to upgrade to the latest HDMU image and so we did.The image installed normally and the box worked smoothly again.Today my friend called me saying that the pink screen appeared on the box and after restarting it from the back switch 00.00 appeared on the VFD without booting.
There is no response when powering it up from the back switch holding the OK button.
The box is about two years old (first RCU generation) and and the last 2-3 months only HDMU was running.
Is there a chance that the HDMU image contains time bomb?
I suspect though a hardware fault.
Waiting your instructions.
Regards.George.
