Surface 2 doesn't turn on

[yaro666]

hi,

I have S2 and it doesn't boot up at all, just black screen. I opened it to see whats inside. I see a red led blinking near RAM (just between the cam and the battery).

When I jold the power button, the led turns off.

Has anyone a servixe manual or know what to do, to see whats wrong?

I have a new battery and new charger, still the same.

a shot in the dark . dose the windows logo vibrate if you touch it?
I'm remembering some stuff my surface pro 2 has done. it might not bee the same.
BUT I would have to touch the windows "button" and it would start up.

I replaced motherboard.

It doesnt react to anything, just pulsating red led on the back of motherboard
