89 No back-light, need schematics to trouble-shoot!
We took apart a Sony VAIO VGN-SZ780 to fix a broken fan and ended up with no back-light. The usual suspects on the logic board seem to be OK, but can't be sure without the schematics to properly troubleshoot the back-light circuit.
Would greatly appreciate if someone has any hints on where to get my hands on the schematics or can share them.
TIA!
EDIT April 4:
Board identifiers: 1-874-192012 and MBX-170
Is dit een goede vraag?

I'm unfamiliar with Vaio boards and couldn't find them. I'll look again today. Thanks!
