also, I tried using an external monitor to rule out issue with display LCD, and I saw a blank screen there too..
My Toshiba L310 laptop (runs on Vista) is not booting. It is having a successful POST, and then the screen is blank with the backlight on. The fan runs. I choose to boot from the CD drive with a bootable disk but still the same blank screen is on. I tried the CD trick using a external CD/DVD drive, this too didnt help.
Can someone tell what is wrong here?
