X200 -> X201 upgrade gone bad

[dxd0]

Upgraded my X200 with a X201 logic board. The basics work, it boots (but doesn't accept the old WiFi card, shame), however, the backlight of the display doesn't turn on. The display itself works (can see stuff with a flash light against it), but the backlight doesn't.

I suppose "some" logic boards are not compatible with "some" displays? Which display would I need to have it work?

A complete lid from an X200 works on an X201 (and v.v.).
Check the fuses on the mobo, you probably blew the backlight one.
Did you remove battery and AC when you made the switch?

Yes, everything was disconnected while I was working on the logic boards.

Good to know that it *should* work. I popped the X200 logic board back in and the backlight came to life again; I'll check the fuses as you suggest.

Edit: Spot on, F1 is a goner. Since I don't stock SMD fuses I'll have to order it, so I checked the others as well but those are fine.
