New LCD Monitor Blinks On and Off

I just purchased a new 22" Visionmaster LCD monitor, connected via digital cable to my ATI Radeon 128Mb video card.
However, it tends to switch OFF to a black screen, and after about 5 seconds it comes back on. The screen displays the word DIGITAL in the upper right hand corner.
Why is this happening, and what can I do to avoid it?
It doesn't seem to like using the digital cable. It works fine using the standard VGA cable, however.
Can anyone comment on this? Is this particular card not compatible?
Thanks!

Hello! Look in your system prefs under the screen saver and see if a "hot corner" is set. It sounds like the mouse is trying to trigger a screen saver or the "display slep" is set to only a few seconds. I've seen this type of behavior with my Dell screen and it's something I'm triggering with the mouse. Tom

New iPod touch blinking on and off repeatedly

I just bought a new ipod touch today, and once I plugged it in to my computer, it showed the apple logo, but then the screen went haywire by blinking on and off. When it's blinking on and off, the screen looks frozen.
I've hardly touched it, what do i do? Someone please help. (please spare me any sarcasm)

Actually, after I got the iPod Touch replaced, it had the same exact problem, which I suspect that I'm just very unlucky because my computer is relatively new. I've been trying to figure this out for weeks.
I did take my iPod back to the store where the associate talked down to me and kind of made me feel stupid (on their computers, nothing is wrong..but at my house, it's pretty much cursed) ..so yet again, I am trying to get the iPod replaced and figure out what is wrong.
I also tried calling, addressing two problems (one of which is irrelevant). They pretty much gave no answer for this question. They told me to restart it, but as I said, no button works after it shuts off.

Satellite L300 29R - Monitor flickers on and off at start up - Vista

Hi from Bxl,
after turning the computer on, when the desktop icons are already visible and the background photo as well, the monitor blinks on and off in black for about 1 second each time.
Then it stabilizes and things 'seem' to work normal.
But then again, I am no expert. Perhaps there are other problems.
I recently bought a new camera and it seems to me that the problem started after downloading the software.
In the meantime I deleted it again but this flickering at start up remains.
What should I do? Please if any solutions, explain to me as to a 'total beginner'.
Thanks so much for your help in advance!

It is not easy to say why this happen.
For me it looks like some component will be loaded in the background and it has something to do with graphic.
We can obviously just speculate why this happen but at the end you must check preinstalled stuff and running background processes to see what the problem can be. What you can try is to install latest display driver offered on Toshiba support page.
At least, if everything works well leave it.

Display blinks on and off

I'm using two displays with my G5. The primary display recently started blinking on and off when I used any "busy" web site, meaning a site on which images constantly change or text automatically updates. The problem occurs in both Firefox and Safari, although it seems to occur more frequently when I use Firefox.
There's no issue with the secondary display. If I move the browser window to that display, I can browse all sites without problems, regardless of the browser I use. Also, when I quit the browser on the primary display, the blinking stops; it doesn't occur when I use other applications.
A self-test of the primary display checked out OK, and the problem persists even though I replaced the monitor's cable. Coincidentally -- or not -- the problem occurred after I installed Leopard on the Mac.
Any ideas about what's happening or what I can do to diagnose?
Thanks.
David

Thanks for the response.
The problem (which I just noticed occurred in Entourage also) resolved after I reversed the monitor connections. I then reversed the connections back to the original configuration, and the problem has not recurred (at least so far), either in the dual-display or single-display configurations.
The only thing I can think of that may have had an effect is that the primary monitor, connected digitally, ran an auto-reset function after I switched the connection to analog.

I am trying to download a variety of files and when it is finished, the Mac freezes up and the task bar continues to blink on and off. I have to go into Firefox and actually quit the application to continue. Any help is very much appreciated

are you backing up files, or doing a Time machine backup, either way, the Time machine will STOP when finished and show "last backup at XXXXXX" meaning its done...... OR if when transferring files, it will show a progress bar on your desktop and vanish when files are copied.
Open up the Hitachi drive (your G drive is made by Hitachi, and the best made by the way).....and see if the files are there.
a MORE VISUAL way is to open the hard drive file, and drag and drop files INTO the Gdrive and you can see them visually be copied there as you do it.
To see your HD on your desktop GOTO FINDER......PREFERENCES....then GENERAL TAB.........check the box marked HARD DRIVES.........then your Gdrive will appear on your desktop........open it from there, and DRAG and drop files from anywhere INTO the Gdrive....... easy visual way to see the files being copied into the Gdrive.

Mac Mini desktop folders/icons and top menu blinking on and off

Hello. I've just returned to my Mac Mini after being away for a few days. Upon booting and having the desktop fully load, I have been experiencing all folders/icons and top menu bar blinking on and off every ten seconds. I have only opened Fire Fox to try and diagnose why this is happening. No solution yet.
I am running Snowleopard with Mavericks and I'm aware Mavericks is a little buggy at the moment (beach ball used to blink on and off every now and again and performance has gotten slow) I only have the HDD replaced last week as the last one failed. I really need to fix this problem soon as I rely on my Mac to work from home.
Any help would be greatly appreciated
Jan

I have sovled the problem! for now at least. I came across another users suggestion to dissable "sync status icons" in google drive as it confics with the finder in Mavericks. I guess this would only work with others having this problem with Google Drive and Mavericks.

Can anyone help me get my Apple TV display to stop blinking on and off every second?

Hi,
My Apple TV is a little under a year old its not version 1 I'm pretty sure it's 2... When I started it up the other night it came on but the display in the screen was blinking on and off about one a second non stop. The white light on the Apple TV is solid white. I was behind an update so I updated it using restore and when it came back on the display is still blinking on and off. When I restart it, the initial apple logo comes on solid which gave me hope but once it transitions to the initial menu screen it starts blinking again. Anyone have a solution?
Thanks for your time,
Dadguy

Hi again,
A couple more things I should add. Everything else plugged into the plasma screen works fine, Xbox, satellite, wii etc...and I did change hdmi cables with the Xbox and the Xbox still worked fine and the Apple TV continues to blink on and off on screen.
Thanks,
Dadguy

Desktop icons blink on and off; computer won't boot

I was recently trying to view a quick time file on a dvd when I got the message that some components may be missing to view the file. I downloaded the components from Avid and put them into my quicktime folder (Library>>>Quicktime folder).
When that didn't work, I removed the older component that had been in the folder and tried to to view the DVD again. This time I was unable to even open Quicktime. I tried to return the "old" component back into the Quicktime folder, but kept getting an error message. Something along the lines of "an unexpected error occured."
I then attempted to reboot the computer. That's when the trouble really started.
My computer now gets to my desktop; all the icons blink on and off, and then the computer seems to try and try to start. I assume that the component I removed was in the start up sequence, but a) I don't know for sure, b) I, of course, can't get on to find out, and c) even if that is the problem, I don't know how to fix it without getting that error message.
Has anyone experienced this problem? Any thoughts? All assistance will be HIGHLY appreciated. Thank you.
LHT

Restart your machine with the Command and S keys held down, and enter the following commands:
mount -uw /
mv /Library/QuickTime/ /Library/QuickTime_old/
exit
Your computer should then continue the startup sequence; if it finishes starting up, the components you installed were responsible for your issue. My own /Library/QuickTime/ folder is empty, so the folder doesn't contain anything critical.

Doesn't start, Apple logo blinks on and off.

My iPod Classic won't start. There's just a pale image of the Apple logo which blinks on and off. Plugging it into various USB ports has no effect.
Dying battery? (I've had the device for about a year only.)

Okay, here's something I found out: charging it with a power adapter instead of via the USB cable worked.
Question: why would charging it with the USB connection not work?
