What does it mean when the USB ports on your Apple LCD flat-screen monitor stop working?

Could be.\n\nTry rebooting the system. That might help.

Small board/chip that inverts power (DC to AC) to the LCD screen.  If it stops working, your screen goes black.  Depending on your skill & confidence level, not too expensive to replace.  Check out www.laptopking.com for parts.

could be one of two things:\n\n- software problems: fix this first\ncheck for driver updates for both your video (graphics) card and your monitor. install the updates. if there aren't any updates then reinstall the lastest version of the drivers for both.\n\n- hardware problem\neither the monitor or the video card is busted. whichever one has a prob, it will stop working completely eventually. you're looking at repair or replace as your options here.\n\n\na 3rd, but less likely, culprit is the actual video settings. someone may have changed those by mistake so that the colours looked all messed up.

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.

try restarting the computer and if that doesn't work check your display settings

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.

It looks like your monitor is either going bad or you have a loose connection.

go to device manager from control panel, control panel>system>device manager>display adapters and either rinstall driver or rollback driver. If that doesn't fix it, the in graphics properties, change you monitor driver to plug and play. that should fix you up, if not, email me if you find any other problems and I can talk u through them

try deleating the usb hub in your System config file.\nThen reboot the computer. \nWhen the computer comes back up it will reload drivers for the port. and you may be able to use it.

OMG! I had a freaking Powerbook that did the same thing. There could be one of two problems. I had mine for a year and it turned out to be the battery was completely dead. After replacing that... about a week later I found out that I had a faulty power adapter. I would check with the company about a warrenty... because according to them... they go out all the time. and a little bit of adivce...look on ebay before buying from apple, it could save you $$$.

define "pop"\n could be a problem with your monitor, video rendering device, motherboard, or power supply. try another monitor to see if the "pop" goes away

Sounds as if your video card has no output.  Check to make sure your monitor cable is not loose.  If it isn't, your video card could have died.

Hello. I have had the same problem with my Dell 15" LCD. I don't know what happened when suddenly I'm playing a game and I'm thinking that the game's graphics are awesome because its raining and the thunder really lights up the screen. Then I realize that my pixels are fading, exactly how you described it. I tried unplugging everything and replugging it in again, but nothing seemed to work. I decided to go back to my old CRT monitor and for a few months that worked fine. As luck would have it, it broke as well. I decided to test my LCD again, and to my surprise, it worked now. After about two weeks, I unplugged everything because I was moving my computer to another room. When everything was replugged, the same problem plagued my monitor. That's when I've had enough. I called Dell Customer Service, which was really helpful, and they offered to replace my monitor with a new one even though it was out of warranty. I don't if there is maybe something wrong with the entire line of Dell monitors, but they sure were helpful and considerate. Of course you have to send back your old monitor, but they picked it up from my house and paid for the shipping costs as well.

Hmm.....If its not the monitor, it's definitely the video card. If you have another computer, try swapping the cards and see if it works. Hope it helps.

There are many situations that could cause that:\n1. Softwares (recover your windows\n2. Hardwares (reinstalling your display card)\n....\n\nPlease provide more about your monitor and situation more detailedly.
