820-2914 MacBook Pro 17

I have a MacBook Pro 17 2011 doesn't turn on, fan spin for one second, what are the first voltages to check?

History of the device? Was the GPU messed with?

 

[Salvatore951]

yes, the Gpu was reflowed. After last reflow it does one second fan spin. Can a shorted Gpu cause this kind of problem or the fan should not spin at all?

 

[dukefawks]

Yeah probably the GPU is shorted or VRAM, especially if the edge bonding glue was not removed.

Reflow is no solution and will not fix anything, it will either make it work for a few weeks or just kill it.

do yourself a favour and do what I do, don't touch 2011 at all, not even parts replacements
