The monitor no longer responds. It remains black. This was after switching from an external monitor back to the internal monitor.
I removed the extra memory module and hard drive. When these pieces were placed into another laptop, the hard drive functions fine, however the extra memory module causes the screen to go black, there too.
I tried to replace the hard drive in the old toshiba, but the screen still remains blank.
Any and all advice would greatly be appreciated.

Your Graphics Adapter may be bad. You didn't post the results of the screen testing in another laptop? Did the screen work? Has the laptop been overheating due to dust build up in the fan, vents, heatsink? Has the Thermal Paste degraded/overheating causing a failure of the Graphics Adapter? When you boot does the HDD blink? Sound? Fan spins? Just no monitor? Any damage? drop? Possible loose connection of the Graphics?
Connecting an External Monitor or Data Projector You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

Hi, Can you tell us please, what - recently - happen to the lap? have it been shocked, dropped down ,,, ?
To test, u can plug external monitor in the VGA-port, turn ON the laptop, after a minute, toggle the display once, or twice, or 3 times to change the display path to the external monitor. Tell us your results Good Luck
Possible disconnect of the wiring harness from the LCD to the motherboard? Might just need a new screen, but always check the simplest first. Flickering may imply faulty wiring or a lose connection in my opinion.
A soon as you can, connect the laptop to an external monitor and switch to that monitor when connected by holding down the "fn" key and pressing F5. If the external monitor displays normally with no colored band, then your laptop's screen needs to be replaced.
If the same colored band appears on the external monitor, it means that your video chip/controller on the motherboard is about to fail, at which point the screen will go black and stay that way. In this scenario, you need to have the chip on the motherboard replaced or the motherboard itself.
Here's hoping your laptop is under warranty still. If it's not, go to eBay and type "Toshiba Laptop Motherboard Repair" in the search window. Hopefully, you can get a flat rate there of $125 to $175 for the repair.
have you tried either switching between external and internal monitor usally Fn + F5 on toshiba or try plugging a monitor into the back and see if it displays.
if you get a display on the external monitor then its probably a screen or inverter fault if you donot get a display to an external screen then it is likley t be the graphics on the board itself.
hope this helps
Ok friend this equipment unlike the rest has a card of video piggy back that is inserted in the system board, according to the symptoms of the fault that you describe, this one resides in the card of video which you must replace to be able to solve your problem. Good luck.
