Streaming freezing while playing, unless I touch the screen every few seconds to keep the streaming actively flowing.

Streaming from iPad, through an app and the streaming will stop unless I touch the screen which seems to wake it up and will begin from where it stopped. Can anyone tell me why it does this? Kind of makes watching something a little annoying. It's as if the iPad goes to sleep, which stops the streaming. Is there a way to keep the streaming going without having to touch the screen every few seconds to have a the streaming continue as a steady feed?
Thanks,
David H.

If you are streaming through an app it may need it to be awake so it can receive the feed on the iPad and then airplay it, depending on how the app functions. You can set the auto lock to never

My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me mad having to put my pass code in all the time and the screen keeps going blank :( HELP!

My iPad keeps locking itself every few seconds, any ideas how to fix it... Drives me crazy as the screen keeps going blank and I have to constantly put in my pass code every few seconds. Can someone help me out please. The pass code lock is set at 10 minutes but it's happening every few seconds :(

I've run into the issue and it seems to be related to an app not fully supporting the iOS you're on, the reboot doesn't usually solve it.
I've solved it in the following manner(s):
1) Backup the device to iCloud, then erase the iPad (Content and Network Settings).
2) Setup the iPad and choose to restore from iTunes/iCloud Backup (wherever you backed it up)
3) Perform any software updates
I have not tried simply performing the software updates (which may fix it, but if it doesn't you won't be able to perform the above steps).
Enjoy.

The screen on my MacBook Pro Retina has horizontal lines and has a brightness flicker every few seconds since june 2013 upgrade of airport utility.

Hi John,
I would take your machine into a Apple service center. Its highly likely a hardware issue. The most likely issue being the display has failed. If there is no external damage to the machines display they will replace the whole display under warranty for you.

After the restore did the phone work properly for a while? Say, a day or so?
If so it is possible you have an app that doesn't let go of memory properly. I reboot my iPhone ( hold sleep/wake and hole till you see the apple logo) every few days. This resets the memory. The iPhone OS has doesn't seem to mange memory very well yet. So a reboot will help with that. I have had my phone almost slow to a stop before I started rebooting. Always reboot after installing a new app. Also do you close all pages in Safari when you are done? This is a good practice. Safari will run in the background and use processor time and drain your battery quicker. Create a new blank page then close all others when you are done browsing for a while. I have also found that certain web site that have animated images like weather maps will turn the phone into molasses. As soon as i close that page it gets faster.
If all of the above have no effect then as Tamara said it is time for a trip to the Genius bar.
Good luck

Droid ultra wont turn on blk screen and phone vibrates every few seconds

droid ultra wont turn on blk screen and phone vibrates every few seconds

Hello es1040,
The Droid Ultra is an awesome device with a wide range of features to enjoy. We're excited to partner with you and get your phone on so you can enjoy said features. Is there any physical or liquid damage on the device? Also, is the device charged? I would suggest doing a reset to get the phone back to normal. Here's a link on how to do so.

Why is my 24-inch LED display flashing black (and sometimes scrambles) every few seconds?

I have recently upgraded to a new iMac: 3.4 GHz Intel Core i7. 4 GB 1333 MHz DDr3. AMD Radeon HD 6970M. 1024 MB. Mac OS X Lion 10.7.4. I have it attached to a 24-inch Cinema Display.
Before I switched to my new iMac, it would blink black a couple of times a day. This was going on for a LONG time, but was not a big deal. However, now that I have switched to the new iMac, it is every few seconds. And it has now added the "scrambled" screen to it's repertoire. Fun. And, as I am typing this...it just went black and has not come back on.
I've read a few threads on this happening, but haven't found any substantial evidence as to what is causing this. It's beyond annoying. Has anyone learned anything new?

Okay. Murphy's Law. As soon as I posted this, I found an answer (hopefully!). My situation fit the criteria at http://support.apple.com/kb/TS4045?viewlocale=en_US and I installed the update and so far, so good. I'll keep you posted.

2.2.1 update and now error message every few seconds

Did the update this morning. All went fine. I have never used airplane mode. So phone was not in it.
Now all I get every few seconds on the phone, even while in sleep mode, and it wakes the screen is message:
This accessory is not made to work with iphone. Would I like to turn on Airplane mode to eliminate audio interference etc… Yes/No
If I do nothing the message goes away and the iphone goes back to sleep.
I tried selecting yes. It put phone into airplane mode. But message stills comes up. Same thing when I selected No.
This error comes up every 30 seconds or so. I have tried hard restarting the iPhone hold down Home and top button until iPhone shuts down. This didn't do anything.
Anyone else having this problem?

This is very weird. You can always restore the phone again in iTunes. If you have proper backups (pics, contacts, music, apps), after restoring, set it up as a new phone so there is no potentially corrupted backup getting on there. See if that works. If not, take it to the Apple Store and have them look at it.

Imovie choppy when importing a vhs tape, stops importing every few seconds

Hi, I'm importing a bunch of homemovies into imovie for a christmas present for my parents and I've run into a few problems. I've successfully done several vhs tapes using my powerbook, a new sony vcr and a dac-100, but for some reason I am having trouble with this tape. It imported fine for about 40 minutes and then it started showing static. Every few seconds static would fill the screen and imovie would stop importing and cut that part out completely, including audio. When I watched the tape on TV it had the same static but you could still hear all of the audio. Anyway, since the static is probably a problem with the tape, I just want to figure out if there's a way that i could get imovie to import straight through the static so you can at least hear the audio smoothly?
If that's not explained very well let me know, or I can provide more detail. I'm new at this, so if anyone can help me I would really really appreciate it. Thanks!
Powerbook G4

Hi jag7423:
You probably won't be able to seperate the static from the audio but you can try. Import the video and then select Advanced / Extract Audio. Then delete the video and see if the static noise remains.
Like I said it is probably a long shot.
SoundSoap is a program that helps reduce some background noises but i don't know if it will help here.

EA4500 Internet Port Cycles On and Off Every Few Second

I bought a EA4500 to replace my old WRT54G earlier this year. At first the router worked fine. After the automatic firmware upgrade to Cisco Connect Cloud, I was never able to get the Connect Cloud stuff to work, constant 500 Internal Server errors when trying to access the router with the Internet cable attached. So I downgraded back to the old firmware and all was well again. Then I started having problems a few months ago, when I would wake up in the morning, the router would be cycling the Internet port on and off. I could usually reboot everything and it would work the rest of the day. I lived with it like this a while, and support couldn't seem to find anything wrong. Eventually it started getting worse, until the point I could hardly ever get it to stay connected. I got Cisco to RA the old router and I figured problem solved. Now while the EA4500 was gone, I used my WRT54G again, and everything worked fine for nearly two weeks while I was waiting on the replacement EA4500.
So today the new EA4500 showed up, I connected and configured it, and it worked for a short time. Then suddenly I lost Internet, looked up at the modem and the LAN light was going on and off every few seconds. So I'm back in the same boat as before.
I've tried changing cables, same setup works fine with the WRT54G. Modem works fine with WRT54G and connected directly to the computer, zero problems. I tried lowering the MTU, turning on MAC address cloning, and various other things.
My modem is a HughesNet HN9000.
Any suggestions or ideas would be greatly apprecaited.
David

OK, the setup as is works fine with the WRT54G, just the EA4500 has the issue. It started working again last night, and was working this morning. It continued to work until about 3:15 PM today, and out of the blue, my computer came up and said the Ethernet connection went off, then it came back on, it did this several times...at the same time, I looked up at the modem, and the LAN light was going on and off on it also. So the router was cycling both the Internet and Port 1 on and off.
My HN9000 has a static public IP, and the IP it's DHCP server gives out is one digit different than it's own IP.
My router is set this way, and this is what it gets if I switch the Internet to Automatic (DHCP):
IPv4 Address: 97.xxx.xxx.194
Subnet Mask: 255.255.255.252
Default Gateway: 97.xxx.xxx.193
Then there are two DNS server addresses. I've tried the router setup as Static IP or Automatic (DHCP) and the problem occurs either way.
The HN9000 seems to pass all incoming traffic straight to the router.
One the LAN side, the router is configured to give out IP's in the 192.168.1.x range, and I have some static leases set. The router is 192.168.1.1.
Everything works with the computer connected directly to the modem, and with the WRT54G in place of the EA4500.
As far as calling Hughes, they won't support the router. If it works without the router, and with another router, they will say it's a problem with the router, which I think it is, just not sure what. Also, just to be clear, I do loose Internet access on my computer when the router acts up, but the HughesNet modem remains connected to the Internet.

Mission control starts on its own every few seconds to once minute.........very frustrating

I bought a new iMac in August. A few weeks have gone by and my new computer is AWESOME. I just switched from pc and have been very happy. But......yesterday when i turned it on Mission Control would start to turn on randomly every few seconds. It happens all the time now, it really *****, and i have no idea what to do about it. I thought maybe i was activating with magic mouse so i tuned off that feature and it still happens. What should i do?

YES!!!!!! After many hours on the phone with apple (very god customer service, those guys really wanted to help) we determined that the keyboard was the defective. They gave me a replacement at no cost and now my computer works perfect once again. One of the indicators that it was the keyboard was that i couldn't make an upper case e using the shift button. By opening opening up Mac OS X Utillities and having me type in the onlline help section we saw the problem persited and they were able to dertime that it was a hardware problem and not the software, from there all it was was a quick trip to the apple store. Good luck i hope my experiance was helpful.

P35 NEO-2 FR won't boot. One beep every few seconds.

Hello, I hope someone can help me
Out of the nothing my computer crashed. There was a blue screen, but only for a split second, so I couldn’t get any information from that. After I tried to turn it back on I only got a black screen.
Messages from my PC:
One beep every few seconds. -- Means: DRAM refresh failure.
The LEDs on the board have the combination red-red-green-green. -- Means: Decompressing BIOS Image to RAM for fast booting.
Obviously I tried another RAM module. But it didn’t help. I don’t know what I should do, because I can’t even get to the BIOS. The screen just stays black.
PS: I didn’t OC or try to flash a new Bios version.
My system:
P35 NEO-2 FR, BIOS v. 1.8, S/N: 601-7345-100B0805092463
Intel Q9300
G.Skill 2 GB DDR2 PC2-6400 CL5-5-5-15 (also tried brand new Corsair XMS2 DDR2 800 MHz CL5-5-5-18)
MSI N460GTX Hawk

Okay, please have a look at this document:
http://www.ami.com/support/doc/AMIBIOS8_Checkpoint_and_Beep_Code_List_PUB.pdf
As you can see, there are two main routines going on after you hit the power-on button:
1. Bootblock Initialization
__ and __
2. POST Code
Your problem description ...
Quote
The LEDs on the board have the combination red-red-green-green. -- Means: Decompressing BIOS Image to RAM for fast booting.
... indicates that your system halts in the first of the two main routines I just mentioned. To be more precise, it hangs at Bootblock Initialization Checkpoint D5, which is defined as follows:
Quote
Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS now executes out of RAM. Copies compressed boot block code to memory in right segments. Copies BIOS from ROM to RAM for faster access. Performs main BIOS checksum and updates recovery status accordingly.
In the last two phases of this checkpoint:
Quote
Copies BIOS from ROM to RAM for faster access. Performs main BIOS checksum and updates recovery status accordingly.
The actual BIOS Code is copied into RAM and checked for integrity. When BIOS corruption is detected (=wrong BIOS checksum), the system will automatically jump into BIOS Recovery Mode (which is a sub-routine of the Bootblock Initialization routine).
Now, this brings us to the actual meaning of the beep(s) you hear:
Quote
One beep every few seconds. -- Means: DRAM refresh failure.
The BIOS Recovery mode (which is not part of the actual P.O.S.T. Routine, but a sub-routine of the Bootblick Intialization Routine) has its own set of Beep Code definitions which are described on page 15 of the document I linked you to:
Quote
Boot Block Beep Codes
Number of Beeps -- Description
1 -- No media present. (Insert diskette in floppy drive A:)
2 -- ‘AMIBOOT.ROM’ file not found in root directory of diskette in A:
3 -- Insert next diskette if multiple diskettes are used for recovery
4 -- Flash Programming successful
5 -- File read error
7 -- No Flash EPROM detected
10 -- Flash Erase error
11 -- Flash Program error
12 --‘AMIBOOT.ROM’ file size error
13 -- BIOS ROM image mismatch (file layout does not match image present in flash device)
Consequently, the meaning of that single beep, that repeats every few settings is not "DRAM refresh failure" (this would be its meaning in the P.O.S.T. Routine, but we are looking at the Recovery Routine), but it actually means:
Quote
1 -- No media present. (Insert diskette in floppy drive A:)
What you have to do is this:
1. Hook up an internal (!!) floppy drive to your mainboard
2. Prepare an AMI BIOS Recovery disk:
--> Download the latest BIOS Archive for your board from the product site
--> Extract the actual BIOS File and rename it to AMIBOOT.ROM
--> Copy the renamed BIOS File to an empty & formated floppy disk
3. Put the disk that contains the AMIBOOT.ROM file into the internal floppy drive that you connected to the mainboard.
4. Pray that the system finds the disk, reads the file on it and performs a recovery flash
