New Gateway desktop monitor blacks out, but power's on...

Anyone have a clue why a brand new monitor would go black shortly after it's turned on? We're on the illiterate side of computer stuff, so any tips would be helpful. Waiting on Geek Squad to call back...and waiting...

Its defective, thats for sure. Its time to take it back to the store and exchange it for another one.

G5 HP Monitor blacks out, says No Input Signal

This happens when the computer warms up, goes away after sleep, but always comes back. Problem compounded by the computer telling me my GeForce FX 5200 graphic card status is "No display connected." What stupid thing have I done or not done. Computer's new, a dual 1.8, so I don't know my way around it; not that I'm at all tekkie. Any obvious help come to mind? Thanx.

I get the video back by either turning "Source" on the monitor off and then clicking it back on, or turning the monitor power off and then turning it back on. In either case, I'll usually get another five to eight minutes before the monitor blacks out again. If I repeat the process, the interval between blackouts gets shorter and shorter until I cave in, put the computer to sleep and come back in fifteen or twenty minutes, after which I get a pretty good run again, fifteen to twenty minutes. Because I do a lot of writing, it's a process of mental harrassment having my train of thought broken. I'm developing a flinch in anticipation, which sure don't make for limpid prose.
I've only had the computer for two months, so it has never occurred to me to vacuum it. You really think that might help?
Can't say how grateful I am to you experts for your attention and advice.

Screen is blacked out but calls and such still coming through...

My screen is blacked out but I still hear texts, calls, alarms, etc coming through. When I plug it in to my computer for a reset it doesn't identify the phone and there are no "portable devices" settings under "manage devices". HELP please

If you restored to factory defaults/new iPod (you did not say the type of restore your performed) and are still having the problem that indicates a hardware problem. An appointment at the Genius Bar of an Apple store is in order..

Since installing yosemite my computer/screen blacks out, but still running

Since installing yosemite last week, my computer/screen blacks out, but still running. I have since rebooted everything, started from scratch and utilizing my external drive transferred all files/apps back. Did not help, in fact it is getting worse. Computer screen blacks out every 5 min or so and have to power up again. Also, continue to get Java message updates even after all have been updated over and over again. Any suggestions? Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Portg Z30-A-1E1 - External monitor blacks out randomly

Very annoying problem - every now and then the monitor blacks out for 2 seconds and comes back.
Monitor is powered all the time.
HDMI cable changed twice and does not solve the problem.
Seems like a change of resolution or a reset - can the problem be in the graphic card? Otherwise maybe the HDMI port itself detecting strange stuff?
Please help I'm getting crazy as I work 90% of the time on external monitor.
Thanks

Yes maybe you are right. Still, annoying not being a fluent French speaker to have to deal with them.... and with 90% possibility that they'll say "if you bought in Italy you should talk to them". I'll try.
PS: another ridiculous thing: you buy a product that has a problem, and you need to pay to call the support service? Really not acceptable....

I urgently need to know how I can connect 8 thunderbolt display, I was thinking with the new mac pro will come out, but I wonder if it is possible to connect an iMac to 4GB of graphics card, but suffers from the imac. thanks

I tightened all HD screws and it didn't help. With the machine running and side of the case off, I physically stopped both the video card fan and the front case fan with my finger for a couple seconds and the noise continued. I also took all hard drives out one by one and rebooted each time. Again, the noise continued until I took out the Mac HD in Bay 1, rebooted, and I had a very quiet, silent machine. The issue is the hard drive in bay 1 that shipped with the computer, it's without a doubt causing the hum/woosh sound. I still need to know if I can safely swap the Mac HD from bay 1 to bay 4 without any issues to the operating system. I would like to try that to see if it dampens the noise but I also want to make sure this swap won't screw up my machine at all.

Monitor blacks out when booting with KVM Switch in the middle

Hi
I have attached my Xserve with an iMac G5 to a KVM Switch. When I boot up the Xserve the monitor blacks out after the apple logo.
I know that the Xserve tries to autodetect the monitor. Apparently it fails in its job when the KVM is in the middle. Everything works well when I remove the KVM and connect the monitor directly to Xserve.
Any ideas how do I disable the monitor autodetect feature - or something?
Xserve (intel) Mac OS X (10.4.1) dkvm-4u KVM switch

Hi all
I did try that. No luck.. Strangely enough, I realized that when the server boots up, the login screen defaults to 85HZ refresh rate. I found a site that explains the plist file that you can change to force it to 60HZ. What is weird it if I boot the Mac connected to another LCD, then move the cable to the KVM, it works. It almost seems like when the mac is booting, it sends some sort of signal just before the login screen comes up, that screws up this KVM. Tried updating firmware, still in the process of speaking with the KVM support people...
very strange..

My new iPhone 5 just blacked out and won't come on. Does anyone know if I will have an issue with Verizon getting a new phone?

MMy new iPhone 5 just blacked out and won't come on. Does anyone know if I will have an issue getting a new phone from Verizon.? I can't even call because I don't have a phone!

Ebony,
Let's see if we can't get this phone working for you! What exactly is happening with the device? Is the screen just out and you can hear that it will still ring, or is the phone completely dead? Please elaborate more on what you are experiencing.

Monitor blacking out and flickering MacPro1,1

MacPro1,1 2 x 3 GHz Dual-Core Intel Xeon, 3 GB 667 MHz DDR2 FB-DIMM, running Lion 10.7.5
Graphics NVIDIA GeForce 7300 GT 256 MB
For a couple of months now, my monitor periodically blacks out for a second and/or flickers. Sometimes it gets really bad and I just have to shut down.
There was some dust buildup inside machine; it has been cleaned, still having problem; have tried reseating video/graphics card.
I have run Apple Hardware Extensive Testing and it shows there are no problems; have checked and made sure monitor cord is securely connected.
Have monitored Temperatures and they all appear to be fine.
I CANNOT FIGURE THIS ONE OUT! IS THE VIDEO/GRAPHICS CARD ... MONITOR GOING BAD ... I AM AT A LOSS, AND IT IS REALLY IRRITATING.
CAN SOMEONE PLEASE HELP AND GIVE SOME INSIGHT?
THANKS SO MUCH!

Most graphics card that old have died of overheating a while ago.
RE: Mac Pro silver tower (2006-2012) Replacement Graphics cards
1) Apple brand cards,
2) "sold in the Apple store" cards, and
3) "Mac Edition" cards ...
... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:
1) Apple brand cards:
• Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5. (This card has just been discontinued and is no longer available from Apple dealers. There may be some new, old stock still available at resellers)
• Apple-firmware 5870, about US$450
2) "sold in the Apple store" cards
• NVIDIA Quadro 4000 Fermi, about US$1200
• NVIDIA Quadro K5000 Kepler, about US$2500
3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:
• SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1
• EVGA GTX 680 Mac Edition, about US$600
The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.
If you are Meet ALL of these:
• running 10.8.3 or later AND
• don't care about "no boot screens" etc AND
• can re-wire or otherwise "work out" the power cabling, THEN:
You can use many more cards, even most "PC-only cards".
One more thing--
Flashed PC cards: There are a good many EFI flashed cards that offer boot screens and behave like official cards. "for more information about using and flashing non-Apple cards, please check out the various sites like Netkas (and others) that focus on and discuss what is known and available. (Not supported or endorsed by Apple.)"

Samsung monitor blacks out

I've been using a Samsung monitor with my 2008 MacBook Pro, running Lion for a couple of years now - it's been rock-solid stable. I use the Samsung as main monitor with laptop as secondary.
Past couple of days, the Samsung has been blacking out - seemingly NOT triggered by anything. If I unplug the cable at MacBook end and replug immediately, everything is fine. I have tried restarting, PRAM reset, Permission repair, etc. Things are hot here in New England at the moment, but stats on heat and fan speed look fine on iStat Pro (the immediate deplug/replug suggests its not a heat thing anyway).
Thanks for any and all thoughts,
Vince

Did some further troubleshooting today, and wanted to share for anyone looking for solutions.
Tried both DVI and DVI-RGB connections (different cables) on the Syncmaster monitor and symptoms were the same.
Tried DVI-RGB into my Epson EX5200 projector - NO SYMPTOMS.
Did some further digging, and there are reports of the Samsung Syncmaster 2333SW doing this with PlayStation, Television, etc. No resolution other than monitor hardware malfunction
Bottom line - this is not an OS X, MacBook Pro issue.

Full screen video on 2nd monitor blacks out 1st screen

When I play a video full screen on a second monitor, iTunes blacks out the first screen and I can't see the Windows desktop. Is there a way around this?

I'm having this problem as well. Apparnetly the world thinks this is acceptable behavior. I do not. I'm trying to work and feed video from iTunes to an HDTV next to me. Why in the world would I want my 3 other monitors to blank???
Tripply amazing is that it's worked this way for quite a long time. Apple isn't fixing it, so they must think this is a great FEATURE.

A new 23" studio display blacks out from time to time

Just got this great new display. Once a day maybe, the screen goes black for about one second, then pops back up.
What could be causing this?
G5, single processor Mac OS X (10.4.7)

One thing to consider, maybe you accidentally move the mouse into the sceensaver hotspot and then once it starts to black out, then you move the mouse to turn off the screen saver and it seems like it blacks out?
Mac Pro 2.66 Dual-Core Mac OS X (10.4.8) Adobe CS2

External monitor blacks out

The external monitor I use with my MBP has stared blacking out - usually for about 30 seconds, sometimes more. Any ideas how I can fix it?
