If this is a CRT, then the horizontal deflection circuit is faulty.
The repair is generally not worth on CRT.

First try leaving monitor power cord unplugged for few hours, to discharge capacitors, sometimes this can fix minor problems.

Test also the display on different computers, you never know that this depends from a faulty video adapter.

More likely you will need to replace the screen.

Flashing magenta screen, blue screen and shutdown


Your screen is bad more than likely. Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays and works ok, then your original monitor is bad. If the Borrowed monitor displays the same as your original monitor, then the Video Card inside the computer is bad.

Screen Shakes on High Resolutions


your rate of refresh is too high, it's refreshing too fast, you need to lower the screen resolution. keep in mind, the tv resolution is much much smaller than a computer monitor. a computer monitor has much higher resolution. so Tv can only handle so much in resolution. if you need a better picture, it always the best to buy a monitor, not a tv for computer to get a good picture. if you have any more questions, let me know.

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.

HP Pavilion 17" screen flashes on and off


Try reinstalling your monitor. You should have a disc that came with all of your equipment.Make sure it is a clean install and there are no other programs running. Also check all connections to make sure they are tight.

If this does not help, do you have another monitor you can install temporarily so that you can work on this problem?

Is this a new monitor installation? You might want to check your hardware compatibility list which you will find under Start>Programs>accessories>compatibility wizard.
