Brand New eMac starts but no video

I have a eMac in a classroom that was bought in the summer and imaged and working fine 3 weeks before school. School time comes around and everything starts up but the video... You can hear the HD loading everything and the startup light comes on as well as the chime. But never any video.
I tried resetting the PRAM, booting from a cd, tried the external to see if it would work... and nothing. I just need a way of narrowing down to what it is, so I can replace it.

Just to clarify, when you were trying to boot from a CD, was this the first OS X Tiger Install CD from the Tiger DVD media exchange (which requires the eMac in question to have a CD-ROM or CD-RW drive only, not the standard combo or super drive) or from the OS X Install DVD? If the boot CD was a troubleshooting / utilities homebrew burned disc, have you checked that the disc will boot other late-model eMacs?
Since you're getting the power light and hard drive noise, the main power management has to be working. There have been problems with Macs failing to wake properly from sleep, but booting from the OS X Install disc should bypass that problem. It would most likely be soemthing blown in the CRT/analog assembly hardware. That's not a user-servicable assembly (the voltage on the CRT yoke is dangerous) and a school Mac purchased this past summer will still be under the one-year hardware warrenty. You could contact an Apple Authorized Service Provider (AASP) or more typically in a school setting, contact the school's vendor.
If there's student or teacher data that needs to be recovered, you can use another Firew0re/OS X equipped Mac as the host to retrieve the files off the damaged Mac as the client using FireWire target disk mode.

Polly,
usually there are multiple models of MacBook Pro per model number, but in the case of your model number (A1502), there’s currently only one model for that model number: 13-inch Late 2013.
To reset your MacBook Pro, you’ll need to boot into Recovery mode by holding down a Command key and the R key as you start it up. When the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk (most likely the top item of the list). On the right-hand side, select the Erase tab. For the Format dropdown, select “Mac OS Extended (Journaled)”. For the Name input box, “Macintosh HD” has traditionally been the default name — I don’t know if that’s still the case for the Late 2013 models. After that, press the Erase… button, and erase its entire internal disk. When it’s finished with the erasure, exit Disk Utility, and select Shut Down from the Apple menu. When you start it up again, OS X Internet Recovery will redownload Mavericks from Apple’s servers and reïnstall it on your internal disk. Once it has reïnstalled, run Software Update to get it up to date, and adjust the System Preferences to your taste.

I have a brand new macbook pro, but it won't let me download mavericks

You have got a Late 2013 MacBook Pro.
This MacBook uses a special OS X Mavericks version which is newer than the one available in the Mac App Store, so you cannot download OS X Mavericks from the Mac App Store now. Instead, if you need to reinstall OS X, you will have to do this through Recovery (hold Command and R keys while your computer is starting up).
You will be able to download OS X Mavericks from the Mac App Store when your Mac uses the same OS X version as all other Macs. This may happen when Apple launches OS X 10.9.2

I am trying to activated a brand new iPhone 4s but the serial number isn't working. Suggestions?

Are you getting any error message or other data that helps to understand why the SR # is not working? Sometimes when entering a serial number a letter or number is entered incorrectly because a 1 looks like an l or an s looks like a 5. Make certain that this type of an entry error is not your problem.

HT4623 I bought a brand new ipad air, but I am not allowed to download ie. pages and keynotes for free, as promised?

I bought a brand new ipad air, but I am not allowed to download ie. pages and keynotes for free, as promised?

The free only counts for devices activated after September. So first you need to activate the iPad (go through all the set up stuff), then, using the same Apple ID you used to activate the iPad, go to the App store and search for Pages, etc. When you download them you should see them for free.
Being free is tied to the Apple ID used to activate a device. For example, I bought my iPod in June, so I'd need to pay for the apps, which is why they're not universally free in the app store.
After you activate the iPad it may take a little time for the app store to realize 'yeah, just got a new device, this purchase is free'. I've seen people say they go right in, see it for cost, then go back in a little bit and the apps are now free.

I got a brand new iPod Touch but I'd like to know if I could exchange or return it so I can get the new one. It has no scratches and hasn't been dropped.

I want to know if this is possible. I'd obviously pay what's left for the newer version, but I don't even know if this is possible. Again, my iPod has zero scratches, hasn't been dropped, brand new. I had a case on it the whole time. Please reply! Thank you.

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.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

BRAND NEW PHONE NOTHING BUT A MESS HELP ME PLEASE

After charging my iPhone (Brand new 16GB 3GS) I go to sync it to my computer. My computer makes the 'ding' noise it does when you plug a USB in but it does it again immediately after.
I FOLLOWED APPLE'S **** INSTRUCTIONS AND I GET THIS:
Below is an example of the full error message this document relates to as given in Microsoft Windows XP.
The software you are installing for this hardware:
<device/driver name>
has not passed Windows Logo testing to verify its compatibility with Windows XP. (Tell me why this testing is important.)
Continuing your installation of this software may impair or destabilize the correct operating of your system either immediately or in the future. Microsoft strongly recommends that you stop this installation now and contact the hardware vendor for software that has passed Windows Logo testing.
*** am I going to do?! Help me please! I spent so much money on this phone for this?!

I get that error ocassionally at the college where I work when we plug USB drives into the workstations. It is an XP error you sometimes get with newer hardware. You can select continue anyway, but I agree with the above poster to check and make sure you have the latest version of iTunes as it has all the latest drivers for the phones. That should solve your issue.

Brand new MB Air: Apple website videos won't play

Just brought home a brand new 13" MacBook Air. Went to the Apple website and couldn't play any videos. Nothing happens. YouTube videos play fine, and the Apple Trailers website plays fine. It's just apple.com that won't play videos.
There are no extensions in Safari (so DivX isn't the problem). QuickTime 10 is installed. It's fresh out of the box. Haven't changed a thing. Anyone have any idea what we need to do to get videos playing from the Apple website?
Thnks in advance ...

UPDATE - we went to the nearest Apple Store today, and played with 6 different MacBook Airs, and found this problem on FOUR of them. They couldn't play the videos on the Apple website. This stumped the sales staff until one of them went into Safari's File menu, selected "Reset Safari", then re-booted ... and it worked!
Came home, did the same thing ... it worked.
So now my question is: why does "Reset Safari" clear this up?

Same setup, some brand new emacs refuse to login

OSX server 10.4.7, OD master, file serving only. I have 11 emacs (10.4.7)to set up for teachers. The teachers already have accounts and home directories, and have been using them successfully for quite some time, logging in from our computer lab (10.3.9) clients. I go through the setup screens, and can successfully see the network, connect to server while logged in locally, and get on internet, but when I add server to ldap in directory access - as I have before on identical machines - all looks correct, but when I try to login as a network user (doesn't matter which one) I get the dreaded 'you cannot login at this time. The home folder for this account is located on an AFP or SMB server" The weird thing is that I have successfully set up 3 identical machines (new emacs) and they login fine. 4 (so far) won't, and I cannot find any differences between the setups. I have tried adding server using FQDN, adding using IP address, removing various cache files, preference files, re-boots, etc. from searces of forums for this problem. Nothing has helped. I cannot track this down to a software update on the server (recently updated to 10.4.7, and security patch) because some work fine, some don't. Another post said to run the command 'hostname' in terminal, and make sure it was the FQDN of the server. IT IS NOT - the command hostname returns the name of the computer - but I don't know what to do to fix it. on the affected emacs, in terminal, 'hostname' returns computer name, eg "mrs-smiths-emac" on good emacs, 'hostname' returns computer name.local, eg "mrs-jones-emac.local"

Hi

As far as I know the TV 40TL963B supports an common USB 2.0 HS interface and the USB memory flash can be formatted in FAT16 or FAT32 files system. So there are no special requirements to the USB flash memory

Brand new PC laptop but Flash keeps crashing on 2 different browsers. Help!

Hello! Flash keeps crashing on my brand new PC laptop. It has crashed on both Chrome and Firefox. I have updated everything I can think of on this PC, including drivers. I have made sure flash is up to date and the browsers I just recently installed seeing as this is a new PC so they are up to date as well. I disabled hardware acceleration about 5 mins ago, I am desperate at this point. Anyone have any idea what could be causing these crashes? Oh, and I have Windows 7 OS, if that gives any insight to anything. Thanks!

Errors/Glitches with my brand new Equium A200 15I (incl video hardware)

Hi,
I just treated myself to a new laptop last Saturday and have thus only had it for about 3 and a half days so far but I noticed a few small things that I weren't sure were errors/faults or if they were just because its new, such as the fact that sometimes I type things with the keyboard and some of the letters don't appear on screen, which I think is probably more to do with me not typing or pressing heavily enough on the keys rather than anything else, its not happening so much now...the touch pad gets a bit sticky too and it thinks I want to scroll up and down when I want to move the cursor not scroll sometimes but I manage to get it to work, I think most laptops have glitches like this and presumably I could help fix it by calibrating the touch pad(?) I haven't had time to look into that yet though... there are a few other things though and most worryingly just this morning I got a video hardware error message, so now im a fair bit worried/suspicious that there may be a real fault with it and would like to know if this is the case, whether its something I can possibly fix (im no real expert especially with hardware but I can always try downloading and installing updates/fixes and that sort of thing if it'd fix problems).
The main thing which is worrying me most, is that this morning a message suddenly came up on screen, warning me that there had been a video hardware error, yesterday evening, which I clicked on a button I think to load more info. and I took this screen cap of it:-
http://img528.imageshack.us/img528/724/errorscreencapcw1.jpg
I thought it may help to show the actual full message rather than just trying and pasting the info., well ok to be honest I didn't notice it let you copy it to clipboard but oh well (oops lol).
I know there's a topic about a similar error but I didn't want to butt in on that discussion as I presume that should be for that persons error to be discussed, mine may be slightly different I don't know... I followed the instructions given in that discussion and checked the device manager and no hardware faults are showing up there, btw it says in the device manager, under display adapters, that its a Mobile Intel 945GM Express Chipset Family, im sure all the A200 15I laptops have the same card but I thought I'd just clarify that. Incase that wasn't the right thing to check I also checked under 'sound, video and game controllers' (as the error said it was a video hardware error) where it lists the only one as being 'Realtek High Definition Audio' and I checked the properties there, on both under properties it says that the device is working properly, with no signs of any faults...
The thing is, I had read online somewhere that there is some issue with the graphics or video cards. I'd read that they can be glitchy and sometimes break down after the one year. I'd also asked my dad about this and we checked that it was an Intel graphics card that came with this laptop, which it is, and we reckoned that Intel chips should be as reliable as any other brand really... so I didn't think that there should be a problem, though if there is I have until next September to get it fixed before the warranty expires!
What surprises or kind of worries me though, is that the error message was only presented to me this morning. It dates the error as having occured at 19:53pm... I was using it last night and infact I went to have a shower and I put the laptop screen down before I went to shower at around 7:35pm, I presumed that its ok to just close the lid and it would automatically go into hibernate mode or something similar(?) im wondering if that had something to do with it, as I 7:53pm would have been roughly when I came back and lifted the lid/screen up again to use the laptop again... I can only presume, given the time it quotes, thats what caused the fault?
It does give me the option to 'update driver software' and 'scan for hardware change' within the device manager, should I run both or either of those perhaps? is this a common glitch? should I be worried at all etc...
Any help is much appreciated, if more info. is needed then let me know and ill clarify what I can. Also in terms of whats installed, I have quite a few programs, for graphics I have an old version of Paint Shop Pro which I installed yesterday morning, it seemed to install fine, thats Paint Shop Pro 7 from Jasc, I also have some converter programs (for vid files, 3GP and stuff), AVG Virus scan, Spybot Search & Destory, DBPowerAmp, FTP Commander, Quicktime and Real Player, fairly basic stuff like that, nothing much else just my old pics and vid files I transferred from my old XP laptop to this one, in my documents... I don't have any high powered or complicated games or anything else like that installed. Also at the time the video hardware error message states, all that was running when I had the lid down (or before I put the lid down) would have been Windows Live Messenger (though im pretty sure I signed out before putting the lid down) and an IE window, im pretty sure thats all, I wasn't working on anything else just checking the 'net...
There are some other things I've noticed too that I thought perhaps I should mention(?), one thing I've noticed it doing is the screen going blank and then coming back very quickly, alot. I've already asked about this a day or so ago as by then I realised that it was only doing that before loading the 'Windows needs your permission to continue' window/message, which apparently its supposed to do and is something to do with the computer switching from displaying the normal desktop to the secure desktop, which I sort of understand lol.
So I believe that isn't anything to worry about but I have noticed over the lastday or so, that the screen seems to do this more, going blank then coming back again, even when that permission message doesn't show up.
For instance this morning when I first put it on and went to check my home page, I clicked on a link at the bottom of the page or wherever to load another page within the website and the screen went blank for a moment before coming back a second later with the requested page. Is this normal too? or a Vista related glitch, or is there a possibility there may be a glitch with the monitor? im guessing it may be more of a Vista thing but I thought I'd ask here just incase, I decided not to pay for any extra insurance/extended warranty as I'm very careful with my items and take good care of them and so I'm being careful to try and spot any faults early on while they may be fixable under the basic warranty and what-not...
Another thing I've noticed is that to start with, when I pressed and held the 'FN' button, a range of black and white icons appeared on screen which told me which F button(s) to use to make certain adjustments, it still does that when I try it now but at other times, it doesn't show the icons, no matter how long I hold the 'FN' button down. That doesn't really matter since I can tell from the symbols on the keys on the keyboard which buttons to press but its just inconsistent, is there a reason why sometimes the row of icons on screen will show up when I press and hold the 'FN' button and other times it won't show at all?
Also sometimes if I move the cursor right to the top of the screen, those icons load as they seem to always be located at the very top of the screen but sometimes this is a problem, if im trying to click on something else and one of those icons comes up instead... im sure you can switch this option off somehow but should I be worried that the icons don't always show when I press and hold the right button(?) just trying to be cautious!
I think this post is long enough and I can't think what else I could possibly add to help, so I'll leave this here. I don't mean to seem too paranoid but thought it best to mention this stuff incase anyone recognises these glitches/errors and can recommend a quick way to fix any problems before they may develop into anything worse... many thanks in advance for any help with any of these issues!!
(mods let me know if im wrong to include so many things in one topic, I kind of did this quickly and I apologise if im breaking any rules I don't mean to, if possible please break this into a few different topics or I can do this, though ill be at work frm 2-9pm today so might not be back and able to check here until Thursday morning (October 4th))

Hi Isla
Your message is really, very, very long. I think its too long to read it twice ;)
. Regarding all your issues on this notebook well. it looks like you have installed many 3rd party programs and applications. In such case its not easy to say if such issues are software or hardware related. But I presume its software.
I checked your screenshot pic but I have never seen such error message. But it looks like something wrong with the graphic card driver. The message says something about Live Kernel Event
A kernel's services are requested by other parts of the operating system like graphic card driver for example.
In such case I would recommend updating the graphic driver. According to you message its a Intel GPU. So you could check the Intel page for the compatible graphic chip driver.
Regarding the FN key issue;
The Toshiba FlashCard utility controls the FN key functionality. I have read in this forum that this application does not run smoothly and in some cases it causes some issues. The new update should solve the problems. You should check the Toshiba driver page. The FlashCard Utility is a part of the Toshiba Value added package.
So finally one more hint:
You should always check for the Vista updates on the Microsoft page. This OS is not perfected and Microsoft releases very often patches and fixes
Hope it could helps a little bit.
If necessary just ask for more info :)
Regards

Brand New iMac...No Video

OK, I know my Macs (been a user since 1995). I'm completely baffled on this one.
I'm setting up my in-laws' new 24-inch iMac. I was trying to show them about video Podcasts in iTunes. I can not get the video to play at all. Audio plays fine...no video.
I set it in the preferences to play in a separate window. I tried various different video podcasts. Nothing. I feel like an idiot here. I migrated them from an old G4 iMac and everything else has gone great. This is just not working!!! Any suggestions???
Interesting thing is I tried a 30-second preview of a TV show and that played video fine. It's just the video podcasts that are not working. Thanks for any thoughts.

Yes, since Friday works for me, the temporary playback of video podcasts are no longer. Did it with iTunes for Mac and Windows probiert. Presumably, Apple has this possibility of playing for video podcasts, as amended. We must now watch the videos now completely download. This is a step backwards, I think!

Brand new U410 Freezes while playing Video?

Hi,
So I just received my u410 through the mail (which I'm panicking about because the box came completely dented on one side) and turned it on and decided to test everything out on the computer. I was watching a TV show and in the middle of it, not only did the video freeze but so did my computer and I thought it was going to blue screen! It made the buzzing noise like when a hard drive is going to fail.
I hope this was just a one time thing and that its "normal"???? This is the second laptop I've gotten from lenovo, a week ago I returned the U310 because of the wifi manufacturing failure.
Please help?? Should I return this one too and say screw lenovo.....?
Thanks,
Linda

If the problem persist, then do a one key recovery. If onekey recovery doesnt solve then return it.

Brand new, getting started in Mac, iOS programming

Hi, I want to start learning to program Mac and iOS apps. I have no prior programming background and REALLY want to learn. Where is a good place to start learning to program for Mac and iOS? I have bought a couple textbooks and watched some tutorials. Would appreciate any input and help.

Vesper,
you don't need to go too in depth into cocoa development if your goal is to develop Open-GL games.. in fact if you know C/C++ you really don't need to know much Obj-C at all...
There's a book from pangea software here that was recently made free that talks about OpenGL game programming on the mac, it might be worth checking out.
http://www.pangeasoft.net/book/index.html
That book will teach you how to open an opengl window, and you can go from there using free resources. Warning though much of it is slightly advanced.
You certainly don't need Hillegass if you're looking to develop OpenGL games. Hillegass's book is "the" Cocoa book, but almost completely useless when it comes to developing OpenGL games. It would be both a waste of time and money if your interest is games programming. It would actually be more relevant to learn how to program DirectX games on Windows than to study Hillegass's book as there are many books that outline creation of a game engine on that platform, but you will need to adapt things for OpenGL rendering.
