Hi colleagues,

need a working dump for Toshiba C855-1KD
Platform: PLF / PLR / CSF / CSR / DSC MB REV. 2.1-

ACPI Flash BIOS version 6.70 for Satellite C855/L855/S855
http://support.toshiba.com/support/driv ... xt=3619590

Hello. Learned the way of the regular installer. Before flashing please save the original dump.

Wish to clarify :

Lap came with display fail issue (internal and external)!
All voltages are checked ok, but TXLOUT signals are absent.

After dumping Bios, got dead lap with continuous blinking led , the bios file is probably not the right one.

So please help with a working dump file for PLF / PLR / CSF / CSR / DSC MB REV. 2.1-

check gpu

Platform is DSC.
Just for test purpose, I reflowed the integrated graphic chip with no avail.

there is no integrated graphic, only discrete - need new chip

Ye, y're right ! I got confused. it's discrete. I rather reflowed the AMD graphic chip for test purpose, with no avail.

You suggest then to change the AMD chip. So no way to fix it for the moment.
I got pro tools for the repair but unfortunately not yet a BGA machine!

3000 amd has no reaction to reflow.only new one needed

Customer agreed to change mobo with a good working used one.

Anyway thanks to every member having contributed to this thread.
