Hi Luciano, great discovery. Too bad that now Toshiba has denied access to those manuals, however those pages are still in Google's cache as today. Who knows how longer will they be? For those who will need this after us, I may say that I learned that if DC power led is flashing an error code, it means that there is a problem with the power supply. Now what problem? That will tell the code, but anyway most likely you are facing a dead motherboard.
