Dead OVI40

I have a friends board on the bench, he accidently touched something .
Now when you press power the screen just goes white and nothing else happens.
When you release power it goes off.
I tried reloading boot loader but nothing happens but screen white.
Do you think the MCU is blown??

AH, Making progress.
I was looking for that thread, but could not find it.

Thanks,

Is that the P1 ? Do you have a suggestion as to where to tap into the 12volts
