Toshiba Satellite Pro C850-1MX bios needed

[Scootie]

Hi guys,
Unfortunetley Toshiba support doesnt supply bios for flashing and I needed for the laptop above which starts but shows no picture. Was thinking to start with a bios programming and if Im correct these boards(PLF/PLR/CSF/CSB, Rev: 2.1 or E89382 HannStar J) have a main and a little bios or maybe if someone has encountered these problems can give me a direction to solve the problem.
Thank you.

sorry i don't have your bios files

was that failure caused by a bad flash or did it happen suddenly ?

i'm wondering how to diagnose a bad bios on those laptops, i have a c850 (not pro) which can be switched on and off but shows no signs of activity whatsoever (back screen, no fan, nothing)..

My client received it from someone as a gift. Amongst many other, the notebook had a crushed screen too which it was changed. Someone checked it for me and said found no ill on the motherboard components. Me thinks its either the vga cip gone or needs a reball or something happened to the bios. I have a personal IR station but its always easier to start with a simple bios flash.

is it a LED screen?
as you may already know if led screen change with battery still attached then it usually takes something out on the M/B, hopefully just the tiny smd fuse near the M/B screen connector

If that would be the case I should still have signal on external vga, right?
