Try reinstalling version 2 and then update to V3.

I recommend that you get your local service engineer to check it.
If you are unable to get it to "install" the OS then there's not much else you can do.

It is possible to try diagnostics mode but this is not recommended and can cause further problems unless you are qualified in its use.

Cheers
Pete

Hello, i replied to the video buy i m posting it here too as it is better for the discussion..

It doesn't even pass to the second boot stage..It halts at the first kernel.
Most probably your cpu board is faulty but try removing and connecting again the panelboard cable (you have to open it).
If this will not fix it i m not sure there are a lot of things you can do apart from buying a new cpu board.
I have only seen some pa900 having serious cpu board issues so far although the cpu board is exactly the same on all the newer models as far as design goes and i believe the cpu is the same too on all of them (600/900/3xle/700/1000/4x) so i don't really understand why only pa900 (3 of them with almost the same issue)..
So try unplugging the cable connecting mainboard to panel board and plugging it in again just in case and we ll go from there to check if there is anything else you can do.
In this state i m almost sure you can't get into any mode (update/test/service) so there is virtually nothing you can do till you open up the keyboard.
As some things cannot and should not be told in public as they are not safe without guidance i may reply to you with pm in specific questions you may ask or things you may need help with.
