Another problem with my screen. After turning the laptop on, the screen flashes gray and black a few times, and then begins alternating red, green, blue, white, and black over and over again. Rebooting doesn't do a thing. Not sure what to do with it. The computer is three years old, and has traveled a bit, so it has had a few bumps now and again. Any ideas about this? Thanks

Re: Another monitor problem
Its a graphics card thing or a connector loose.
If graphics then as it is integrated with the main board there is nothing that can be done.
If it is a loose connector- well can you or any one take a look see

It might be the input from the graphics card. Try swapping the two monitors' feeds to see if the problem is with the monitor or the card. The monitor seems to be going into a screensaver mode since there's no signal. The flashing light could mean there's a power supply problem, or no signal.
try plugging into an external monitor.. if the screen looks ok then it is most likely the laptop LCD screen is bad.. had the same thing on a HP laptop .. replaced the screen and all was well again with the world...
You either have a hardware problem with your video card. ( may have pop out of socket when you plug in the monitor) or the cable is not allow communication to the monitor. As long as the amber light comes on you know you have power so focud on data cables and hardware.
Access BIOS and test if the flickering continues.
If not, it is a Software problem, do a full system recovery If yes, it is a hardware issue, better contact Toshiba tech support to have your LCD repaired if you are still in warranty.
If your not in warranty, you need to check out the LCD harness that might have been loosely connected.

try to decrease the screen resolution. try to 640 x 480 then raise to 800 x 600. for old CRT monitor maybe have a problem with 1024 x 768. if decrease not work, then you might have a hardware problem, you need to purchase a new one. try the test first. maybe you can test with your monitor of your friends first :-), if work, you need to purchase a new one.
