Screen mirroring - screen on TV freezes at regular intervals

Hi,I have a strange problem when mirroring the screen of my new Sony Xperia Z3 Compact on a Netgear PTV3000.The phone connects without any problems to the PTV3000 but than regular screen freezes start to appear (sometimes immediately after connecting, sometimes it´s ok for few minutes and then these freezes suddenly start to occur). No matter whether I play a video or just browse photos. The mirrored screen on the TV freezes at regular intervals - every 3-4 seconds the screen freezes for about 2 seconds. These freezes appear only on the TV not on the screen of the phone.The strange thing is that these freezes don´t appear when mirroring the screen of my laptop or of my older Xperia Z1 Compact using the same Netgear PTV3000. This problem only occurs on the new Z3 Compact. I already tried to hard reset the phone, but it didn´t help. I also tried to change the channel and bandwith on my Asus router, but this also din´t solve the problem (I didn´t expect that it would help as the older Z1C and laptop can mirror the screen on the same network without any problems, but anyway I tried). Are you aware of this problem when mirroring the screen of the Xperia Z3 Compact, is there any solution? The phone is running on Android Lollipop 5.0.2, currently there is no update available for my phone. Is there a chance that an update will fix it?

Hi
This sounds very strange. However, you have posted that this issue happens sometimes and not every time.
In my opinion I dont think that software could be responsible for this issue.
Maybe a looses cable connection? But believe me; its not easy to say whats wrong without any diagnostic tests.
You have suggested that you have sent the unit to the shop.
I would recommend contacting the Toshiba service partner in your country. The technicians should check the notebook.

MacBook Pro screen flickers and freezes after Snow Leopard/Safari 5 updates

Hi guys,
I have a silver 120GB 15-inch MacBook Pro from Summer 2007 with 3GB RAM and 25+GB free space which has recently begun to freeze irrecoverably. The first appearance of these symptoms seems to coincide with my installing the Snow Leopard 10.6.6 update via Software Update.
I'm not particularly well versed in computer technology, but will try to describe my problem as detailedly as possible.
What happens is this:
1. I start the computer as per usual, with only a couple of startup items. Everything's fine.
2. I start working. Use a lot of Safari 5 for browsing websites, often with some kind of Flash or "Flash-type" content such as banner ads, videos, even full Flash designs. I may also have programs such as QuickTime, VLC or an image editor open, if not necessarily "actively" doing anything. Everything's still fine - I'm able to both browse websites and watch videos as usual.
3. After a while of active working - say, 1-3 hours - I notice browsing websites gets a little choppy. Display features such as the file list view in Finder may or may not appear properly. The rotating wait cursor may or may not appear from time to time.
4. Immediately after symptom no. 3, the next time I start to watch a video, either via Safari 5 (say for example something on DailyMotion.com) or a file via QuickTime, something goes wrong.
Following no. 4, one of three things invariably happen:
5a) The video freezes and the entire screen flickers from black to the screen view very quickly two or three times, after which the computer or screen appears to freeze. The cursor still moves, but nothing reacts to it - open windows become completely unresponsive, nor does the top or any other menu react in any way to clicking. The "menu row" of application items, which normally appears when I move the cursor to the very bottom of the screen, doesn't appear. Restarting "blindly" by pressing the Off-button once and pressing R doesn't work. I'm forced to do a hard reboot, after which the computer is once again fine until the next two hours of active working. This usually happens ONLY when I try to watch a video in Full Screen-mode.
5b) I notice the video freezing only just in time, and am able to pause it and "esc" out of Full Screen-mode, and the computer remains operational. However, as soon as I again try to play video in Full Screen-mode, everything described in 5a. happens.
5c) The video stops playing, and the screen reverts momentarily to pale blue before switching to the login screen. I login again with my details, and everything appears to be fine again until the next two hours of active working. The computer "starts up" a lot faster than with a hard reboot. This usually happens ONLY when I've tried to watch a video in its original size, i.e. when not in Full Screen-mode.
This happens 1-4 times a day, and it appears to depend directly on how much work I've been doing on the computer. The less I use it in the course of a day, the longer it takes until the next time it freezes.
So, in a way, I'm able to replicate this problem. 95% of the time the screen has frozen while watching or starting to watch (usually already when starting to watch) video footage, but it has also frozen a couple of times just switching between e.g. Safari 5 and an image editor or browsing a website with a Flash banner ad or embedded video content (which however hasn't necessarily been playing); today, the screen froze when I tried to open a website made entirely with Flash.
Although it could be just a coincidence, I believe this issue first appeared when I updated Snow Leopard to 10.6.6 via Software Update alongside some other pending updates, including as far as I recall one for Safari 5. The update process appeared to have gone well at the time, though, and was not interrupted in any way. I have never had this specific problem with the computer/screen before, though.
I've read a couple of threads here regarding very similar issues with newer MBP models than mine, in which it has been suggested that the fault may lie in a malfunctioning NVIDIA GeForce graphics card. Now I've had that replaced already once because my screen went unexpectedly completely blank after a forced reboot 1-2 years ago (I don't remember exactly), but according to my System Profiler info the card still a GeForce 8600M GT. Can it be failing again?
I've also had some kind of a RAM card failure once. As far as I understood it, one of the RAM cards had fried and was preventing the computer from starting up. I replaced the bad 1GB card with a new 2GB one and the problem was resolved. Before the computer died, there were also other symptoms, but they were not similar to these.
I'm also doing the Apple Hardware Test tomorrow. Any other suggestions, though, than the graphics card?
*Could this have to do with Flash or Safari 5?* Just hear me out. Even though my computer has frozen from watching a video in just QuickTime, Safari 5 has always been open in the background at the same time, and more likely than not with websites with "Flash" content open. And come to think of it, before I performed the Snow Leopard and Safari 5 updates, I used to have daily problems viewing Flash video in Safari 5, the video content either suddenly showing up as "Plug-in Failure" or crashing the browser; I've had both Safari 5 and the Safari 5 Flash plug-in "quit unexpectedly" countless times in the past, almost daily. Sometimes the "Plug-in Failure" could be fixed just by refreshing the browser view; at other times, Safari 5 would stop showing Flash content altogether - Flash banner ads (such as Google ads), YouTube and other Flash videos, everything - until I quit and restarted Safari 5. BUT - since the day I updated everything via Software Update, I don't remember this happening; it never gets to "Plug-in Failure" now. Could it be worth trying to use e.g. just Firefox for a while or is there something (e.g. Adobe Flash) that I could try reinstall? Or am I just clutching at straws here?
Thanks for reading this long, long post!

Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck!

I have a new Macbook Pro. When watching Youtube videos, it works perfectly until I attempt to watch the video in full screen. When in full screen, the video freezes immediately and the audio continues. When minimized it works fine as before. Help?

I have a brand new Macbook model A1502. I am taking online college classes that incorporate youtube tutorial videos. I can watch the videos if I don't maximize the screen to full screen. When in full screen, the video freezes immediately and the audio continues uninterrupted. I can press escape and go back to the previous screen and the video continues to play with no problems. Can anyone help me please? This machine is literally just out of the box with maybe an hour of use. Thanks in advance

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

I have a football game recorded on a DVD R disc that I was trying to view on my MacBook using DVD Player. The video comes onto the screen, but immediately freezes, and then disappears. An error message comes up saying that DVD player unexpectedly quit.

I have a football game recorded on a DVD+R disc that I was trying to view on my MacBook using DVD Player. The video comes onto the screen, but immediately freezes, and then disappears. An error message comes up saying that DVD player unexpectedly quit. My MacBook operating system is Mac OS X, version 10.5.8. DVD Player is App version 5.0.3, framework version 5.0.7.
However, the DVD+R works on both my Dad's and my brother's laptops. My Dad's laptop is an iBook G4 with Mac OS X operating system, version 10.3.9. The DVD Player is version 4.0. My brother's laptop is a MacBook Pro with Mac OS X operating system, version 10.7.2. The DVD Player is App version 5500.26.1 and framework version 5.5.0. The DVD+R plays fine on their laptops, but will not play on mine.

Lao Bo,
yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
find / -iname filename -print
This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
find /Users/username -iname filename -print
Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
cp -p filename_returned_by_find /Volumes/USB_volume
If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
ls /Volumes
Please let me know if you have any trouble with these commands.

I have a MacBook Pro, it recently started freezing upon startup. It would get to a blue screen and just sit there. I've tried booting in safemode to run disk repair and still doesnt help. If I do manage to get past the blue screen, it still freezes

My mac keeps freezing upon startup. It will get to the blue screen and promptly freeze. If I manage to get past the blue screen, and open up youtube on google chrome, it will freeze before it loads youtube. I've tried safeboot and disk repair, nothing seems to work. I even tried to factory reset it but it wont connect to my internet when I reboot with power + option.. any ideas?

This can be used to boot the machine and delelte enough files to get it to boot normally.
.Create a data recovery/undelete external boot drive
Read about storage drive so you can store your extra stuff.
Most commonly used backup methods
Also here to see how a full boot drive slows the machine down
Why is my computer slow?

Can anyone identify screen problem that freezes (pic)

Can anyone identify my screen problem that freezes? Alternately I get this image all over screen (see pic) or just a few horizontal dotted lines.
I have to force reboot.
Any thoughts appreciated.

Thank you.

Look into what security software you are running and disable it and also go to apple.com/support and search for
itunes store connection issues by actually typing that into the bar next to support then scroll down to one of the TS articles and begin a jounrey of internet explorer configuration.

Screen flashing and freezing

I have a 2008 Mac Pro, which has served me well since I got it, at least until a day or two ago. At that time, it started exhibiting sporadic black flickering on screen, paired with freezing. At first, everything would freeze except the audio, which would continue playing uninterrupted, and after a minute or so the system would unfreeze like nothing happened. Now, though, it seems to have gotten worse; the system doesn't seem to recover after a flickering episode, and even the audio will get stuck into a one second loop after a while.
I tried resetting the PRAM and the SMC. When that didn't work, I tried restarting into Lion Recovery mode with Command-R. For some reason, that sent me right to a reinstall screen, but it didn't matter, because the screen started flickering and the system froze almost immediately after startup. I'm pretty sure that what it froze in was a separate recovery partition, so that should rule out any software issue. I'm guessing that my video card is fried, but I'd like to see what others think; I'd like to avoid buying a video card that I don't need.

2009 Mac Pro 3,1, GeForce 8800GT, 6GB ram.
I have recently had the same problems. Screen flickering, tiling and freezing previous to this video settings I've had for a long time just changed. I am not sure if it is my monitor or graphics card. My graphics card was replaced once already. This is acting a little different this time.
I also reset pram am still running 10.6.8

MBP 13" Screen Flickers and Freezes After Upgrading HDD

Hi There,
I have seen on here and a few other forums that people are having issues with graphics cards or overheating that is making the MBP screen flicker and freeze.
Mine has been fine until yesterday when I installed a new Seagte 1tb HDD. It works ok, but every now and then the screen starts to flicker, half of it goes black and the system freezes. Sometimes it's just for a few minutes, but sometimes I need to do a hard reset by holden the power button down for 5 seconds.
Here are the details:
MBP 5,5 13" (2008 I think - Can't remember)
Boot ROM Version:
MBP55.00AC.B03
SMC Version (system):
1.47f2
Version 10.6.8
2.26Ghz Intel Core 2 Duo
8gb 1067 Mhz DDR3 (Just upgraded, but before the hard drive and no issues)
1TB Seagate Momentus SATA HDD
As mentioned, I upgraded the RAM a week or so ago and it has been running fine. I put the new hard drive in last night and after a few hours, the flickering started.
I cloned the hard drive using SuperDuper and it all started up fine.
So far, I have verified and repaired permissions, checked SMART status and run a SMART Utility diagnostic. All comes back ok.
I cleared the PRAM and installed smcfan control as another forum with similar issues said it was a overheating problem and running the fan control program should fix it. I did that at 8am this morning and it has run great all day. Come 5.30pm, the flickering started and then it froze.. GREAT!!!!
It's so frustrating, I was really looking forward to having my MBP upgraded and running fast again.
Any ideas or tips would be very welcome.
Thanks in advance.

set old HD. If problem will gone - you have weakened power supply or internal power converters. Yours new HD draw more power during spinup or something - so voltage on internal bus lowers and memory or videocard freaks.
5.30 PM looks like a time when there begins a lot of load on city energy grid - so voltage in wall socket goes a bit unstable, it may also add to problem.
if problem is gone when you are on battery power - its power supply. If it persists or get worse when on battery - its internal power convertors.

Ipod screen and controls freeze for 1 min but it still plays

Hello, any and all help is appreciated.
Listening to music, my ipod's screen and controls will freeze for about a minute, but the ipod still plays music when this happens. It happens every 5 minutes or so. Pretty weird. If I turn on the backlight and it freezes, the backlight will stay on for 1 minute until the thing unfreezes and it kills battery time.
Also, it will remember any buttons that I press while it is in freeze mode and when it unfreezes, it will perform those functions. (i.e. if i'm listening to a song and the screen and controls freeze, it will continue to play that song. if i use the click wheel to change the volume, it won't work, but as soon as it unfreezes, the ipod will remember my actions and lower the volume eventhough i tried to adjust it 30 seconds ago. make sense?)
Has this happened to anybody else? Is there anything I can do?
