Screen blacks out for a few seconds occassionally

Sometimes my screen blacks out for a few seconds, then comes back on again. I have an original Titanium powerbook. Is this a warning signal of worse to come? I know I should replace the computer soon, but it's working just fine for now. I just don't want it to die before I've moved on to a new machine.

Hi Julie,
Obviously no one can predict with certainty what the future will bring, but if I were in your shoes, I would certainly think there was worse to come.
Many things could be causing this, but it sounds like a short circuit or bad connection, possibly with the display cables running through the hinges, or where they connect to the logic board. It could also be a sign of the display dying, though they usually just get dimmer and dimmer or simply die.
Does the "blinking" correspond to any movement of the PB?

Ver 10.0.1. Entire screen blacks out for a few seconds when scrolling.

I recently updated to Reader X 10.0.1. Now when I scroll through a large document my entire screen blacks out for a few seconds. So far it has recovered. I get an error message saying that the NVidia nView driver (ver. 135.50) has stopped responding. I am running Windows 7 Pro on an HP Laptop, feeding to a large Samsung monitor. Never happened prior to this update. Any fixes/ideas?

Screen blacks out after a few seconds and won't return to normal state.

I have the 30 gig ipod photo that i got about a year and a half ago. Whenever I look at the screen to access music or anything, the screen blacks out like there's a screensaver or something and won't return back to normal. Even after I reset it, it stays normal for a few seconds and then blacks out again. The backlighting still works so it's just a bright black screen and I have function of the click wheel because it clicks everytime I move up or down. I already tried restoring it so I am all out of options. Anyone PLEASE HELP!!! Thanks
Steve

This happens rarely but consistently! I't seems to happen about 5% of the time waking from sleep. It MAY be more prone to happen if I had been moving with it in my bag, but it can happen at any waking time after any duration of sleep.

Macbook Pro Retina blacks out for a few seconds at a time

I have a new (2-3 weeks) Macbook Pro 13" retina display. A few times since I've had it, the screen went black for about 10 seconds and then came back. Any idea what's up with this? Is this something to return the machine for, or is a software issue? Has anyone else had this happen?
Thanks!
Stacey

MacBook keeps blacking out for a few seconds

I have a weird new problem. It started blacking out (I thought it had switched itself off but it hasn't, it comes right back as it was after a few seconds) around every half hour or so. But now, just a few days after the problem began, it is blacking out every few minutes. Luckily it comes right back on and I don't lose anything, but it is annoying and certainly not right! Any ideas what this could be related to and how to fix it?

It sounds like it is either the inverter cable or the inverter board. Probably the latter. You can find repair guides, parts, and tools on ifixit.com. If your computer is under warranty, take it to an Apple store and have them fix it.

After applying update my apple tv2 will randomly go to a black screen that lasts for a few seconds. When it gets back to normal after a few seconds it acts like the video never stopped since its farther along in the timeline. This happens with all video content wether its from Netflix or streaming from my iTunes library

You might try restarting the Apple TV by removing ALL the cables for a 30 seconds. If that doesn't help try using another HDMI cable.

Try to backup and restore you device in itunes...restoring the device is like removing the iOS software off the device and re-add in a newer software, after you have restore you device, MAKE SURE YOU SET UP YOUR DEVICE LIKE A NEW DEVICE, DONT NOT RESTORE FROM BACKUP!!... give the device a chance to use the newer software and see if the issue still persisting, if the issue still on going then its would be a hardware issue.
Call Apple Care and see if your device is still under warranty to get it replace

Hi i have a macbook pro retina 15 inch mid-2012, my speakers occasionally fizzle out for a few seconds and then return to normal. Do you know what this could be?

Try a SMC reset

Audio briefly drops out for a few seconds

I about half way through a recorded Keynote presentation, the narration audio drops out (goes blank) for a few seconds. It doesn't affect timing.
I've checked the narration file and it's just fine. Narration was done in Garageband. I've re-recorded the presentation again, and it drops out at exactly the same place. The narration was done in one step, so it's not a problem with the method in Garageband.
Keynote 9, v 5.3. 27" iMac, OSX 10.8.5, 16Gb Ram.
Any ideas of how to solve it?
Many thanks,
Bill

Unfortunately there's no fix for this problem that plagues Classic since release. Considering that a new generation appeared I guess we have no reason to expect a fix anymore.
I also have the problem and it makes the iPod Classic less desirable to be used as a music player than a generic $10 (no name) usb stick.

Audio cuts out for a few seconds

Hi,
I'm not sure if anyone is experiencing this but it happens to me all the time and it's so so annoying.
When playingback the timeline on CS6 the audio cuts out at random places and then it comes back, then it goes again for a few seconds then back again,..while video keeps on playing.....this is just random and it can happen as soon as you press play or after a few seconds and it happens when audio is stereo, mono, mp3,wav,aif, you name it.
Also, it happens regardless of playback quality or timeline render status (red, yellow or green). My computer is quite fast + 24gb RAM so I dont think the PC is a problem, It also happens on a different computer within our studio.
Needless to say that editing under these circumstances is becoming impossible/frustrating and I'm even considering finding other software to edit with! I've found others with this same problem at cretive cow http://forums.creativecow.net/thread/3/935424
If anyone from Adobe reads this, please help!!!
thanks in advance

Network connection to Deskjet 3050A keeps dropping out for a few seconds

Every few minutes (sometimes only a couple of minutes, sometimes a fair bit longer) an alert pops up in the Notification area of my Windows 7 computer telling me that "Scan to computer is no longer activated. The network connection has been lost" (at least I think those are the exact words - it is only onscreen for a few seconds at a time). Scanning and printing appears to work fine otherwise *except* that I cannot print large document files (e.g. photos), because printing stops when the network connection is lost and, even though the connection appears to come back up again almost immediately, does not appear to carry on where it left off.
I think I've tried all the "standard" advice - i.e. remove and reinstall the HP software and drivers, checked for updates, given the printer a static IP address, made sure the wireless channel is well away from any others nearby, printer (and PC) close to router (and signal strength good), all to no avail.
Any suggestions where to look next? I've had the same Wi-Fi network in my house for a few years now and no problems apparent.

Hi Roymondo,
What is the brand and model of your router?
Try changing the channel of the router to 11, or change the encryption to WPA.

Herculean,
It is a Sky badged Netgear router. Can't tell the model, sorry. It is already on Ch11 (advice elsewhere on this site is to use Ch1 or Ch11). I'll maybe try changing to WPA - but with various PCs, phones and iPads already accessing the network, I may just leave it until the weekend, when I will have a bit more time to spend on it.

Videos stopped playing... I get a black screen then plays for a few seconds and freezes. Have downloaded the latest Adobe flash player and it did not help.
