Help white screen and fan running

[Kloksi]

Hi everyone.
I changed topcase on my MBP 13 " from late 2009. When i start it now i get only white screen and fan is running like a crazy. I am wonder if i did a big thing and blow up logic board? I tryed with cmd+alt+p+r but nothing happends.

Thanks

regards Kloksi

Can you clarify what you mean by top case? Are you referring to the lid or the palm rest area?

If it's the lid, chances are you either need to reseat the video/flex cable at the logic board or at the back of the LCD - they can be extremely finicky.

Top case is case with keybord. With other words i moved everything to other case
