find a dead one (they made millions) and swap out parts. or go buy a cheap microphone.

If the monitor actually has a built in mic, you will have to connect a cable from it to the "mic in" jack on your sound card/motherboard, there isn't any way a standard VGA cable can carry that signal back to the comp. Look for a plug, or a separate cable coming out of the monitor.

It's time for a new monitor. Loss of focus is one of the symptoms of a picture tube (CRT) that has reached the end of its life. There is an internal focus adjustment that might make some improvement, but it will never look right again. The only cure is to replace the tube, but that is completely uneconomical. A new LCD monitor will cost less than a replacement CRT, if one can even be found. And setting up the replacement needs special tools and programming software not available. Dispose of this one appropriately (take it to a recycler to keep hazardous materials out of the trash) and treat yourself to a new monitor.

As far as the cd drive goes, get that replaced cause with the door closing and shuttin on its on, it could broken pieces of debris in there thats causing it to do that or the board inside of the cd drive is broken so either way replacing that would solve that issue.

As far as the USB ports are concerned, try hooking up other USB devices such as a USB keyboard, USB Mouse, flashdrive. Try other things to see if you get the same thing, if you do then that means the motherboard is bad cause all of those ports connect to the motherboard.

As an alternative solution to try, if you don't have anything important to save off of the hard drive, you can restore your computer back to factory defaults and then try the usb ports again and if they still dont' work then you know for sure the motherboard is bad. At that point you can replace the motherboard or find a USB card that plugs into one of the PCI slots. That would give you other usb ports to try.

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. May need to check the caps in the G-2 supply circuit. Also you may have a CRT going flakey. Just a slight G2 level adjustment may suffice also. Good luck

you need a microphone, unless your computer recognizes your monitor as a mic installed too

Yes you can reformat your computer to windows xp, but it will run very very slow, so i don't recommend it.

There is a problem with your hard drive. Try taking the hard drive out, remove the battery, push the power button for approx. 10 seconds. Re-install the battery and re-install the hard drive. If the same message comes up again, try to boot the computer off a windows installation disc. If this all fails, you just may have lost your hard drive.

you might have changed the screen resolution or the refresh rate that your monitor might not support. So you better get into the safe mode by clicking the Function key 7and 8 then use the option called safe mode.
After the windows starts log in to the administrator profile, right click the mouse on the desktop then select properties. A display settings window will pop up, in that change the screen resolution to 1024X768 and bring the monitor frequency rating to 60 or 75 Hz. Now apply the settings and restart the system in normal mode.

If still the problem persist then in the monitor control select "auto adjust" to get the things done.

Your video card or on-board video is kaput. If it worked fine on the other system, but not working on this one ... then you've blow the video.

One note: When the computer is ON, do NOT unplug and re-plug in the monitor. You'll blow the video card.

Luckily, add-on video cards are cheap and readily available ...

it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

Blurry image is usually due to either a bad picture tube or failure of a part in the monitor called the flyback transformer. Both of these parts can go bad with age and use, and this is a pretty old monitor now. It is not worth trying to repair this; a new 17 or 19-inch flat screen is pretty inexpensive these days.

The microphone is wired to a connector on the back of the monitor which has a little symbol of a microphone by it. You connect this to the microphone jack on your computer. You can use the same kind of cable you would use to connect the sound output from the computer to a set of speakers. Once you plug in that cable just make sure the microphone is turned on in Windows and you're set to talk.

If this doesn't answer what you wanted to know, please add a comment with any other questions, and please take a moment to rate tis solution if it's been helpful. Thanks for using Fixya!
