    Hello, I will explain as detailed as possible the problem:
    It's a Satellite A500-18R (PSAR3E)

    Suddlenly, this morning, after working fine for about hours yesterday... the laptop don't POST: no image (not even the retro-illumination).

    Tried with external monitor, reseat the memory (interchange modules), remove dvdrw, remove integrated tv tuner, remove wireless module... Nothing.

    The A500 lights: the "on/off", ac power led, and power led. No beep, no warnings.

    I tried BIOS recovery using "Crisdisk", replacing the BIOS.WPH with the only BIOS I could find on the local toshiba support page (version 1.90).

    I don't know if its a VGA problem, BIOS corruption (if I find the original BIOS I could try the crisis method, or what...)

    Before this, there were a strange error about an USB port, about keyboard... (sorry, I can't remember the exact error) and there were no devices attached at any USB...

    I hope you can help me to get back to life this Satellite.

    Well if you've used known good memory and it still doesn't POST externally or on the internal LCD, you likely have a bad video circuit...which would mean replacing your motherboard..
