Toshiba R50 no video

[pippo_one]

Hi everyone
I have a Toshiba Satellite Pro R50-B-107 part no: PSSG0E-00100HIT
mainb.: FALESY1 A5A003821010 A.
I replaced the keyboard for some keys that I had to press hard to write the letter.
when I turn it back on I have no signal on the video and on the vga / hdmi
i tried to replace the ram
I was able to find schematics ... but I ran some tests:
5v, 3.3v 1.35v are there.
the CPU heats up and the fan runs constantly.
could it be the faulty bios?
Pls can anyone help me?
thank you in advantage

First remove the main battery and CMOS battery from the mainboard, press and hold the power button for about 30 seconds to discharge power from the mainboard then re-insert everything, turn on the tester, if not successful use a programmer to extract the bios from the chip, post it here.

Ok, Thank you .... tomorrow I'll try
I went to the Dynabook site (ex Toshiba) and found this executable bios, but unfortunately I am not able to extract the Bin file of the Bios
I'll post it to you in case you manage to extract the files

Unfortunately I can't extract the exe files from the Dynabook site so I can't do anything else.
