Our Sony Vaio desktop now occasionally displays an orange light in the blue "on" light, and sounds a tone.

The temperature inside yourt computer is too hot, pls check your internal fans if they are working properly. This is bad and you can damage your processor permanently.

Hold F2 while turning on your computer. This will allow you to enter bios settings, you can cancel both sounds and the animation there, or you can turn the volume lower. I have a Vaio VGN-A130 and it works that way.

It could be a 'wake on lan' event.  Depending on your computer, OS, and network adapter, search for that to find out how to switch it off.

There is an additional battery inside the case, did you replace it also? Could be that it actually is coming on and the contrast needs set. Try turning it on and while pressing the beta function key, press the up arrow.

I'm not really sure I understand your description. But I can assume two things:\n1. Since you said your laptop is 3 years old, its probably LCD backlight starting to become faulty. LCD screens has a backing layer that provide the light to illuminate the colors on the liquid crystal panel. I suppose you can get it replaced, although... may be a difficult find, if not, expensive.\n2. There is a possibility about faulty or leaking liquid crystal panel. Usually leaking panel produce vertical lines. But these lines usually very striking, can be in one or combination or white, red, green, blue, or black, and will not respond or erroneously respond to graphical changes.\n\nYou can have it checked up, of course.\n\nGood luck

Swap monitors. If he gets color back, then you've identified the issue. If not, it's probably the video card. Identify the card through windows device manager and update the current driver.\n\nMight not be a bad idea to run a virus scan, either.

The UV light has a cycle time that is faster than your eye can detect. Your computer monitor also has a refresh time, again, way too fast for you to see. But if the 2 times line up, it looks like your computer screen is flashing and you can just barely detect it. Highly annoying! Get a regular light bulb lamp for your computer room and leave the flourescent off- that should take care of it.

If it's there even after you reboot, it sounds to my like your LCD panel is shot.

If you have a motherboard with onboard sound that could be the culprit.

it sounds like a row of dead pixels. \nthese are very hard to fix and usally mean getting a new screen, since it would proberly cost less to get a new screen.

Black--or blank ?  \n\nIf it's black, then It sounds as if the power saver function might be on the fritz.\nUsually, striking a key or wiggling the mouse brings the last image on the screen back up.  Does the monitor have a small light on the front that is green when the screen is active? If that light turns yellow when the screen goes black, that tells you that the power saver function is on.  \n\nIf it's blank [not black], then I don't know what to tell you.  Call tech support and try not to lose your temper with the overseas representatives.

you might have accidently touched the sound card or whatever you call it which might have broke it or unplugged it a bit or even moved it out of place a little. Wheck if its connected

i had that problem with one of my LCD screens i would check the cable between the computer and the screen(the cable that has a blue head on both ends) see if anything is stuck inside the area that plugs into the back of the computer and make sure that its pushed in all the way.(this was suggested to me by a friend)\n\nedit---\n\nYeah, you are experiencing a blue shift which happens to some LCD monitors after extended use. The previous poster is correct the red is going out in it causing it to look more blue. Your monitor is getting ready to fail and unless you have another one sitting around to use check out any number of Viewsonics (at around $200) from Newegg, http://www.newegg.com/product/productlis...\n\nBefore you ask, no, there is no way to fix this problem.\n\nI quote Conradj213 (I asked this question again and this was one of the answere I got, I believe it to be true)
