MONITOR FLASHES ON AND OFF

Hi,
If you have another working monitor, then you can connect to make sure if its a issue with the computer tower or the monitor. You can also follow below steps:-
1. Turn Off the system----> Disconnect all the cables except keyboard, mouse and monitor---->Then press & hold the Turn ON button for 10 seconds--->Reconnect power cable with mouse, keyboard & monitor---->Turn ON the system
2. Check the light status at the back of the computer tower where the power cable is connected, if its flashing or stable LED.

External monitor flashes on and off randomly after wake from sleep

I have a Mid-2009 13" MacBook Pro 2.26GHz hooked up to a Samsung SyncMaster 2033 External monitor via the MiniDisplayPort-DVI connector.
After waking from sleep, the external monitor will go blank for a fraction of a second at random intervals (display on the MBP remains normal). The flickering clusters are about minutes apart, while flickers within a cluster (usually 2-3 flickers per cluster) is of order seconds apart. "Detect displays" will not make this go away. The only way I can make it go back to normal is to unplug-and re-plug the MiniDisplayPort connector on the MBP.
Anyone else got a more elegant solution to this that does not involved wearing down the displayport?

I tried this. No change. However, I did start playing with the Display settings. Oddly enough, when I change the disfunctioning monitor to 720p it starts working again. Does this mean anything to anyone?

Monitor keeps flashing on and off

I have a mac G4 quicksilver running 10.4.11. The machine runs fine for what it is. The problem is with the monitor. I had an old apple display hooked up to it which began to flash on and off --- for no reason. I would unplug the monitor for a while, plug it back in, it would work fine for a bit...then the power would flash on and off...on and off...over and over. So, I thought the problem was with the monitor. I got a second monitor from work, which has never had any problems, plugged it into the G4 and before long, the same thing was happening to the new monitor...power turning on and off, on and off. For a while it will work...then just go off.
Since the same thing is happening with both monitors, this leads me to think it’s something with the G4...but I don’t know what. Maybe the port where the monitor plugs into on the back of the computer is bad?? Is that possible?
Does anyone have any ideas?? Can someone point me in the right direction of what I need to check?

Hi! For starters open it up and see if the video card has a fan on it and if so verify if it's working. Once you are sure of that you can start troubleshooting the problem better. Tom

Computer display flashing on and off

So for the past couple weeks, whenever we turn on our computer, our display flashes on and off to the point to where its practically unusable. Eventually it stops after at least half an hour of blinking, but I was wondering, what could be wrong and how could I fix it? The computer isn't really affected, between flashes it isn't shutting down and the log in is still available, however, it only shows what I'm doing for a second before flashing back off. We tried switching displays but that didn't work either. Is there anything that could be done or should we just get rid of it?

Glad that you found the cause, expensive as it may be. I am not sure about this Out of Range message. What sort of monitor are you using? Most will connect and the Displays preferences self adjust.
Within the preferences are a number of display resolutions and refresh frequencies (in Hz) but these are not always shown (for example with my notebook monitor it displays resolutions not refresh rates (always the same for the built in monitor) but when I attach a monitor, such as HDTV or projector, I am offered a range of rates for each resolution.

Second Display flashing on and off randomly

Since upgrading to Lion, my second display (ViewSonic VX2235wm) flashes on and off frequently. There doesn't seem to be any pattern to it. Has anyone else experienced this behavior? This problem is with a second display hooked to my 2.4 GHz Core 2 Duo iMac. It's driving me nuts!

I've since tried other resolutions and haven't found any others that are stable. I've used the monitor with another system and had no problems and the problem started immediately after the Lion install, so the issue is clearly Lion-related.
I haven't heard of many people having this issue, so I'm contemplating upgrading the monitor to get around it. (Longterm, the 1360x768 solution is unacceptable to me as it stretches the image.) I think it may be specific to a few makes/models of monitors and possibly even to a graphics chip/monitor combo. I think if it were more general, there would be more noise about it: a two monitor set-up isn't uncommon.

Pages not loading / loading slowly / flashing on and off

MacBook Pro
OS X 10.5.8
Safari 5.0.6
I have had trouble with loading pages on Safari lately on my MacBook Pro. Some take forever to load, and when they do, they load either incomplete, or not at all, leaving a white screen (even when some images appeared, they disappear). I started noticing the problem the worst when I installed an app for an online focus group that I took part in. The app's purpose, I think, was to monitor my browsing, so they could collect data to see where I was shopping for phones, going on social networks, etc. When the app was connected, safari simply did not want to load; when it was off, it worked better. I have de-installed it (I think) using their de-install function. However, the problem has continued even without the app running.
Another problem that has recently appeared is that some pages (specifically, my gmail) have started to flash on and off at times. At first it happened during the use of the app, but it still occurs even after de-installing the app.
The only other thing I think might have affected my macbook is that we recently installed a time capsule as our router (I think my husband needed to upgrade our OS on one of the laptops in order to make it work? Not sure, he may just have wanted to upgrade it in order to connect our new iPads.)
I will say, that my Safari / internet experience has been rather slower than it was when I first got the computer, and has gotten a bit annoying over the last few months - not terrible, but I know it's just not working like it should.
1) What can I do to alleviate the loading / flashing issue?
2) Are there any steps I can take to "cleanse" my computer of unneccessary items that may be bogging it down?
Bonus: What do I need to do before loading a new OS on my current Pro?
Many thanks for any advice you can contribute!

Hi ...
1. Try a Safe Mode boot.
Startup your Mac in Safe Mode
A Safe Mode boot takes a longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from the Apple () menu.
Mac OS X: What is Safe Mode?
2. Reformat (erase) the hard drive. Insert the install disc while holidng down the C key.
Unfortunately, a reformat will erase everything off the drive back to factory settings but may be the only way to erdicate any left over files associated wih that app.
Before you do that, you could try searching for anything related to the app using Spotlight > Mac Basics: Spotlight
Any software that monitors online activity is bound to have an affect on a browser.

4400 (flashing on and off)

Hello experts,
I have a MSI G4Ti4400, I purchased about a year ago and it is having problem displaying, the screen keeps turning on and off ever 5 to 6 seconds (a flash on and off). What should I do? How do I make exchange with MSI if this item is broken?
Thank you all,
Mike

Mike,
It would help if you listed all your specs so we would know exacly what we were looking at. Then I would try swapping monitors with another comp and see if the problem stays with the comp or follows the monitor.
Take Care,
Richard

HT3180 My apple tv box no longer turns on, the white light constantly flashes on and off but no signal to my tv. All devices still pick up airplay but not actually playing. Restoring the box has made no difference, any clues?!

Was the restore done via iTunes?

If so then you may need to take it to Apple.

IPOD NANO FLASHING ON AND OFF
see if this helps

Ipod flashing on and off

Alright, I had to do a full restore on my computer and lost everything. Plugged the Ipod in afterwards, and lost all my songs/movies. Well now it told me that I had to download the update in order to put new songs on. I did. Now the ipod is flashing on and off and wont let me do anything. I tried reseting it, and it turns off, but as soon as I let go of the buttons it goes right back to flashing on and off. I need some help. Anything anyone could tell me?

I have the same problem, created first when iPod updated on Friday night. I returned the month old iPod for a new one, installed and was downloading library when the new Ipod went into the same catastrophic failure.
HERE IS THE FIX: (walked through w/ Apple Store Rep)
1. Make sure there is power to the iPod (with all the cycling, your battery is probably drained).
2. Toggle the Lock Switch on top of the iPod 3 or 4 times, then hold Menu and Center Button down simultaneously (same as doing a reset).
3. When the Apple Logo reappears, hold the Center Button and the Play/Pause button down simultaneouly.
4. If all goes well, the screen should say, at the very top, Disk Drive Mode (or something to that effect).
5. If you have been running off computer power, disconnect then reconnect the usb cable.
6. Open iTunes
If all goes well, the iPod connection should appear on the iTunes screen with the opportunity to Restore.
7. Restore your iPod to factory settings. Once the download is complete, you should be back in business.

When i plug in my ipod touch (8gb, 3rd generation) it doesn't turn on and the apple logo flashes on and off. how can i stop it and turn on my ipod??????

when i plug in my ipod touch (8gb, 3rd generation) it doesn't turn on and the apple logo flashes on and off. before this it wouldn't turn on unless it was plugged in.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

6700 Classic screen flashing on and off since scre...

I have just changed the LCD screen on my 6700. The new screen works fine whilst the phone is in use, but as soon as the normal standby happens, ie after about 20 seconds, the screen starts to flash on and off. As soon as any of the buttons is pressed the screen stops flashing and is on and back to normal. I have tried resetting to factory default. Tried to update firmware, but the version is 10.50 and is unable to be updated.
Is there a way to obtain the latest version of the firmware via my PC so that it can be uploaded to the phone?
Is it possible that there may be a fault with the screen or ribbon cable, which is strange as the screen work fine and displays all pixels when in use.
Any suggestions as to what can be tried next?

Thanks for speedy reply.
Yes I did change the screen myself as the local approved Nokia Repair Centre would not replace the screen under warranty as they stated that cracked screens are not covered by the Nokia warranty. They then mentioned that they had none in stock anyway and were not placing their next order until 24th October.
I have now put the cracked screen back into the phone and normal operation has been resumed. From this I conclude that although the new screen worked fine when the phone was in use, there is an inbuilt fault that causes the flashing.
Thanks for the info on the updates, that was the process that I was trying to use. Once i typed in the code number from the phone, the website said that 10.50 was the correct firmware.
