Flashing Status Light

Hi,
I switched on my Mac Pro today (after using it yesterday) and it won't start; no starting chime or anything. All I have is the status light above the ON switch is flashing continuously; there is no pattern to the flashing as suggested in the user guide - it just flashes constantly.
I have disconnected all external devices and re-seated the memory cards and PCI Card for my eSATA drive but the Mac will not start and the light continues to flash.
I'd be grateful for any ideas or suggestions.
Thanks,
Cliff
Brighton, UK

Specifically which mac pro model do you have?
There are other diagnostic leds on the processor board besides those near the dimms. Look carefully around for others that may be lit.

Dead MacBook : nothing on screen , flashing status light (6 times)

Hello
My Dad has a MacBook (early 2006) which worked flawlessly until it did not boot one morning.
Now he has a black screen, nothing when powered up except, if you maintain power pressed, 6 times flashing status light.
- Restoration CD did not do anything because it could not load (CD doesn't eject, has to use the "business card in the slot" trick to eject the disc).
- All resets did not do anything (power button for 5 secondes with no battery or power cord, cmd + option + p + r either)
- Could not run diagnostics
- Apple certified repair center saif motherboard is fried, costs the price of a brand new MacBook to change it.
Do you have any idea about what happened ?
Do you know how to reset something ?
Do you know what those 6 flashes mean ?
I read restoration CD can be used while status is displaying 3 short flahes, 3 long flashes. Does it work on a dead MacBook ?
Thanks a lot in advance everyone !

Sounds like a simple dead motherboard, there's no better explanation than that, I'm afraid. If you didn't get AppleCare, then you're out of luck.

Powermac flashing status light error and adding memory boards

I bought a used Powermac G5. So far it won't boot, there is no image being delivered to the monitor, and the fan revs like a vacuum cleaner. At first the status light gave series of 3 flashing lights which the online manual (I don't have the specific manual for this machine) says is incorrect memory board or similar message. However, last time I turned on the Powermac the status light now gives single flashes which diagnostic meaning is not even mentioned in the online manual I am using. Does anyone know what single flashes mean? As far as the memory boards are concerned, what is in there now are: Apple memory module M9296G/A (Samsung PC3200U 30331 0413 256MB DDR CL3) in both inner slots, and Hynix PC3200U 30330 0411 256MB DDR 400Mhz CL3 in both second to inner slots. Are these the correct boards? I have on hand 2 other boards from a broken iMac G5. They are Edge Tech 1GB 5380601-40. Can these iMac boards be added to what is in the Powermac or substituted for two of the existing matched boards if they are the wrong type for the Powermac? Both the Powermac and the iMac run Leopard OS. I have also ordered a new battery for the Powermac. The existing battery is dead. Could that cause flashing status light? Thanks.

Status light flashing

My Apple TV was set up and working fine. I attempted to move it to another TV and now I have a fast flashing status light and no picture. Imoved the device back to the original TV and still have the same problem.

Welcome to the Apple Community.
If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
Connect the micro USB cable to the Apple TV and to your computer.
Open iTunes.
Select your Apple TV in the Source list, and then click Restore.

My airport time capsule did not set up successfully, and then status light flash amber

Hi, Guys
I am the first time user of the time capsule, please help how to proceed?
I have set up the first time and my airport time capsule does not set successfully, then I try to reset to factory setting. After this, although I use the ethenet cable to connect the router to the airport, the status light flash amber, always, even after the reset.
Also, I can see that airport time capsule base station from the wireless network when airport is plugged in. However, when I want to access to it.

Thanks for your guidance, but the product is really anoying. First, I am sure that the airpor utilities is 6.3.
and I also follow your instruction that to set the IPv6 as local link mode. But still get the same error as mentioned in my first post.
Therefore, I have tried to use the bridge mode but could not find it, and therefore still can not set it up successfully, even though I reset the factory again(press the reset button 5 secconds at least).

Apple TV loses picture output and status light flashes rapidly after 5 minutes hooked up via HDMI - DVI cable

Apple TV connected to a 2005 50" plasma monitor with DVI input via belekin HDMI to DVI cable. Unit worked perfectly long enough to get it connected to the wireless network and begin the itunes registration process when there was a loss of signal message on the screen from the monitor and the Apple TV status light flashed rapidly and continuously. Reset and reboot yeilded flashing rapid status light and no output detected from the monitor. I contacted support online and was told to return the unit to the apple store. I returned home with another brand new apple tv and connected it in the same manner with exactly the same results. Is there something with the HDMI - DVI interface that is causing this? Are there known issues with the HDMI - DVI connection to Apple TV with older plasma monitors?

The Apple TV doesn't actually support DVI. Some have managed to get it to work others have had varying issues with it.

What happens when the status light keeps flashing quickly?

My status light on the front keeps flashing quickly. Is there a fix for this?

If it's within the warranty period, then return and exchange it. If not, then you have to do a restore with a USB Mini cable.

Three status lights keep flashing on the base station

I was using my Airport extreme, it was a-ok, then the power went. When the base station came back up all three status lights starting flashing rapidly and simultaneously and since then i cannot get any signal from the base station. I've tried to unplug for 5, 10, 60 mins then re-plug....it still goes back to the same situation. I had this problem before when i just got this replacement base station and usually after unplugging the power chord and waiting for say 1 minute, then plugging it back in, the flashing stopped and the base station started sending a signal again. Except this time all three signal lights continued to blink after re-plugging. Can anybody help at all..I could use some suggestions..I have already tried using the re-set button, it doesn't work. Airport admin utility cannot pick up the base station because there is no signal coming from it..I've checked the manual and it says that the base station has failed its power on self test...what can i do now...I had asked this question b4 when it was initially giving trouble (and i didn't have a manual handy) and was told that it should b ok..that was when i had the chance to return it to an apple-authorized service provider....now i don't so i would like to know what to do....this is a replacement base station!

Kurt,
You posted in the AirPort Express forum. You would probably get better help/suggestions from the AirPort Extreme forum.

I was checking another thing, usually the switches we use here in my work supports a maximum of 14W per port or 15.4w, this wap is consuming 15.2w
Is this the problem??
the strange to me is that,in this same sw I have several WAP and they all use 12.2w
The device type in sw for WAP usually appears as LAP1131AG-AIR-E-K9 ... but this WAP appears as Ieee PD ...
What problems do you think is it?

All three status LEDs flashing means the device has failed its power on self test:
http://docs.info.apple.com/article.html?artnum=107457
...and you need to get the base station serviced.
Hard to know exactly what happened to your Base Station "when the power went" as you described it. Sometimes the line power spikes that occur immediately before or during a power failure can damage electronic devices.

Airport Express status light is flashing yellow

My Airport Express status light is flashing yellow. It has worked in the past, but not recently. I thought it might be a location problem so I moved it to within 6 ft of the computer and it is still happening. I tried the reset button and that didn't do anything. Any other ideas?

Have you done a factory reset?

3 status lights flash rapidly only after unplugging it stop

Whenever I use Airport setup assistant to make changes to my existing setting, and when the base station should be restarted it stops sending a signal and then all three status lights flash rapidly and also simultaneously. This is a replacement base station as the previous had its wan port fried. When it was first plugged in it gave this same problem. Only after plugging out the power chord and waiting for say 1 minute, then plugging it back in did the flashing stop and the base station started sending a signal again. This also occurred during the first set up using airport admin utility. It hasnt happened since (when using admin utility)but continues to happen when I use airport setup assistant. Is it sumthing I should be worried about?

Sounds like your Airport Base Station is operating just fine - I wouldn't worry about it.

AP Express status light flashing amber for no apparent reason, network works fine

AP Express status light flashing amber for no apparent reason, network works fine, any ideas?

It flashes amber when there is some kind of conflict. If the internet is working but the amber light bothers you, airport utility ahould tell you why your airport is reporting a problem.
If airport utility thinks your airport is normal and the amber light bothers you, do a hard reset on the device

My Time Capsule doesn't want to (hard nor soft) reset, and the status light keeps flashing quickly.

About two weeks ago, my Time Capsule's status light was flashing rapidly orange/green simultaneously.
Unplugging the power supply worked.
However, now this trick doesn't work anymore, and a soft nor hard reset of the Time Capsule doesn't work either.
The Time Capsule can't reset anymore, doesn't send out WiFi-signals, and its status light keeps flashing rapidly green/orange simultaneously.
Thanks for your support.
Zander.

What model is the TC? Please give the number from the base, A1xxx.
It sounds like the reset has been forced in and is not releasing. I think whatever the problem is you will have a hard time fixing it.. it will need replacement .. it is just a question of what is possible and that depends on its age and model.
