Question about Toshiba Satellite Pro L300-EZ1005X Notebook PC
I have had this problem several times with other Toshiba notebooks to the extent I almost cringe when anouther person tells me they are once again having the same problem. Hopefully, the following steps I give you will correct your problem... if not, your mobo may be damaged.
There are 2 levels of checking I want you to go through in order to try and fix this. The first is a minimally invasive procedure which wont require significant intrusion into the chassis. The latter will require a more involved dismantle of the laptop for troubleshooting . . . but first:
Rule out the obvious and maybe make it all better in a couple of easy key strokes >>>>
Please don't be offended or insulted by this first, very rudimentary check. I am sure you have already checked this,but just in case, this very simple next check could mean the difference between enduring 30 seconds of embarrasment and 300.00 for a new laptop because something got hosed when you cracked open the chassis unnecessarily trying to fix a sneaky,common issue. Try starting the computer and as it turns on, simultaneously press the “Fn” key and whichever numeric key also shows a monitor image and the text: LCD/CRT. This is a key combo switch that tells your computer to route the display output to an external monitor instead of the laptop panel. There are 3 possibilities – LCD (laptop screen) Only --- LCD and CRT (external monitor) Simultaneously – and CRT -(external monitor) Only. Try pressing the FN and numeric key combo a couple of times in succession immediately when the Toshiba Splash Screen appears – this is generated by the system BIOS and just because you see the splash screen only means that the laptop may be still set to output to an external display device only and just has not executed that instruction yet. I would also attach an external monitor to the laptop and try to boot.... if the display appears on the external, or if hitting the key combo causes the laptop LCD to come back on, then stop, grab yourself an ice cold Rolling Rock Beer (or Coke if you are not 21) and celebrate a simple easy conclusion to another laptop Maalox while pondering the exact phrases of praise and admiration you will be sending to Fix-Ya about me later from your restored lap-top. :-) If still no display.... take a deep breath and lets try the following procedures in the following post (too much text for a single post sorry)

Toshiba laptops are very good normally but don't boot up if there is a
device in the USB slot or a CD/DVD in the drive.
If it still refuses to POST, remove the AC Adapter, remove the battery and remove the hard drive.
Power the unit up without the hard drive and it should complete POST and complain that there is no hard drive. If that doesn't work remove AC adapter, ensure battery is disconnected and remove hard drive and RAM. Try again. If it still doesn't work, you have a mother board fault and it needs a service centre. www.Toshiba.com will help you out.
If it does work at one of the options, when you have closed the laptop down, replace the RAM first and test, then the Hard Drive.
Hope this fixes your problem.
