Damn L850/C850...I`ve repaired few of them by reflowing vram modules...those boards are very sensitive to heat...Usually gpu dies...

Ah well...who would know...gremlins maybe I usaually fix them by replacing gpu...
I think C850 would be successor of HP 6735s in number of repaired units,at least in my shop...

i got toshiba c850d-109, motherboard model H000052450
no power at all,, no voltages to fan or anywhere. i get 0.7v 1.0v on some battery pins.. rest nothing. 19v comes to motherboard and few componets near dc jack but nowhere else. this board has no water dmg and cant see any visible short, any suggestion?
thx

Re: whats is the big problem of L850 toshiba with no image.

No image even after replacing GPU on this model - failed Intel PCH. You will also notice that it gets very hot on boards that have no image. On working boards it is just warm. Either way, it is very bad design on this laptop (and many others), the PCH has no kind of cooling, and thus it fails.
