This can be caused by:

1.The monitor is not connected properly.
2. Bad hardware

Verify that the monitor is properly connected in the back of the monitor as well as to the back of the computer.

If the connections are OK it means that monitor or the video card is probably damaged. To test which component is dameged connect a different monitor to your computer or connect your monitor to a different computer.

If the other monitor works on your computer it means that your monitor is bad and if your monitor works on another computer it means that you probably have a damaged video card.


The solution to your problem is probably not the monitor, follow these steps:
1. Connect and boot your computer with 2 different monitors.
2. If it does'nt work with either of them the problem is from another computer component.
Posible Problems:
1. Your video card may be damaged or moved from it's slot.
2. Your proccessor may be damaged.
Posible solutions:
1. If you have computer hardware knowledge open the case
2. Remove the Video card.
3. Insert it back or insert another video card from a friend.(if it works with your friends card, obviously the video card is the problem)
4. Restart your computer and see if it works.
Now if it does'nt work after that you will have to replace your proccessor with one that works, from a friend, because you say your computer boots but if your monitor doesn't work you don't know for sure if it boots corectly.
The steps above are only for people with hardware knowledge, if that is not your case you should contact a computer service.

My computer may have a won't go past the toshiba logo screen when I turn it stays on a black screen with a small white me please!

Hi. Try to drain the electorstatic energy of the motherboard. Remove the battery and unplugged the power adapter. Press and hold the power button for 30 secs then put everything back in. Turn on the computer and see if you will be getting the screen. If screen wont show up then this is most likely an LCD problem.

Unable to format, partition,ins. os and boot my toshiba TE2100..

The CMOS needs to be set to first read the CD or DVD drive before it reads the Hard drive. Once your XP disk is in the drive it will boot from the CD drive and setup the computer, The CMOS is acessed by turning on the computer and immediatly pressing either the deleat key or the F! or F2 key try each one till you get to CMOS then look for boot section. Set CD drive to first your HD drive to second.

Toshiba TE2100, Sreen flashes rapidly on and off, If I tap it on the side, it stops flashing, bu intermitently starts again. Seems lide aloose connection in the wiring to screen, as computer will still...

Sounds like you are correct about the loose connection. There is a thin ribbon cable that powers the monitor.

You will have to download instructions for taking your laptop apart, but once you do, simply reseat the ribbon cable. That should fix it! Good Luck.

It sounds like your Operating System is gone. Try to run a repair by pressing the proper key that kives you your comuter's booting options. If that doesn't work, then probably reinstalling your operating system will fix this, as it has fixed the same problem for me in the past. Thanks

Setting correct screen resolution for external monitor

Instead of looking to the laptop drivers, try looking for the monitor drivers. If there aren't any, then research the video card for the machine to see if the specs you have are wrong. If there aren't any drivers for the monitor, then the drivers at Toshiba's support site should work, since they don't, I'm going to say it's in the video card.

Toshiba TE2100 blank laptop screen

Try holding the Fn key down and then press the F5 key a few times, waiting a few seconds each time to give it a time to switch between display modes.

Hi all,

This problem happened to me also but luckily I fixed it.

1) Check to see if you still have the screen displaying something. it might be faint as the back light may not be on.

2) If you can still see something there then it's either the backlight tube or the inverter.

3) Out of the 2 it's most probably the inverter which powers the backlight tube.

I did it for my laptop and it works a treat. Good luck
