Macbook Pro 2013 no longer boots My MacBook Pro 2013 no longer boots. I've tried different modes like safe boot, utility menu, boot from other device,... but I instantly get a white screen. Wiping the NVRAM, removing the battery or the SSD does not work. 

Has anyone an idea what I can do or how I can reflash the firmware maybe this will solve my problem?
the only thing left no removed  - try removing RAM modules one at a time ( try each sodimm individually in either slot - do not forget to power unit off ( fans not spinning) as you meddle inside the unit ;) ... 
also - did you disconnect the dvd drive and did you inspect the logic board for possible water damage?

by the look - the unit does not pass POST  either due to dGPU or RAM/northbridge
