The screen is not completly black if I hold the laptop to direct light I can see the image, but barely. I tried going into safe mode but it still had the same resolution. I also tried to brighten the screen but it did nothing. Is this the video card or monitor?

Re: Toshiba psa70u Black screen
Hi there There is a bad connection or the backlight/inverter underneath the screen has gone, the fact that you can see the ghost image tells me that the video card is fine. Take it to a PC repair shop and have it sorted out, it should be fairly inexpensive to repair. In the meantime you can use an external monitor with laptop until you can get it in for repairs

I have same problem with HP laptop, one of the things i did the first time was to take off the battery and press on/off button for twenty seconds, put the battery back and turn it on. That works for me and i hope to help you. THX.
More than likely the screen. The inverter normally causes things on the desktop to be barely visible. The whole screen looks black, but with a flashlight you can see the images are there when the inverter is bad.

Usually when you see a reddish hue then black.....is indicative of an inverter or backlight failure. Hold the laptop up after it is started and look from the bottom toward the top. Try to shine a flasklight at the bottom of the screen upwards...see if you can see the windows startup screen or anything that gives an indication that the laptop is running and booted to where you can faintly see something on the screen. If you can barely make out an image, then 9 times out of 10 you need another inverter. There are rare occasions that a backlight bulb will fail, but this is rare and most backlight bulb failures are from shock damage. The inverter can be changed by simply removing the screen bezel, unplugging the inverter and changing it. If the bulb has been broken or burned out, it is more cost efficient to simply change out the lcd panel. The bulb sits in a channel under the lcd panels inside the aluminum framework. The panel has to be disassembled to remove it.
You need to hold down the FN button and hit F8, let go, then leave it for a couple of seconds and keep trying till an image comes up. and if that doesn't work, give it a try with all of the F buttons. OR you just have a broken laptop
First test is hold a flashlight at an angle to the screen to see if there is a faint image. If you can see the image with the light then the problem is with the laptop's display, either the backlight went out or the inverter is bad.
Second test is to hook an external monitor by VGA cable. Image should be complete and in full color if the onboard video card is functioning.
Please post comment with results for more direction.
Sounds like the back light on the screen isn't working properly which will need to be replaced if this is the case. Check for a very dark image on the screen when it is booting up in a well lit room, if you can see the computer start up then it is the back light.
Ok, from the beginning. Can you do a cold boot and get into the bios? (is there an image on the screen then)
Secondly, can you connect to an external monitor and see an image?
Did it do this only when it was heading in to hibernation? If so, it sounds like the power management needs some adjustment.
If there's no image on the external monitor, you may have a video/motherboard problem, or it still could be the operating system/power management.
It all depends on if you have video in bios.
Let me know.
