G4 powers up, but apple display doesn't

Hi all,
My G4 (sawtooth) powers up, but the display does not. Display has power but no image and light stays amber and not green. How do I tell which one is broken? Can I connect my G4 to another mac like a powerbook or Imac?
Any help is welcomed.
Thanks,
Nelson

Welcome to Apple Discussions Nelson,
Firstly it's best to post exact details of your setup, as it makes it easier for people to help! (Make and model of monitor, type of connection etc).
First thing to try is to make sure the cabling between computer and display is all ok: make sure the VGA (I'm guessing) is screwed in firmly. Alternatively try another cable. You could also try the monitor with another computer - this will help you identify where the problem is.
The other thing to check for is whether the computer is starting up: can you hear the hard drive working for a minute or so after you switch the machine on? If so, and if the monitor works with another computer it could be that the computer's output resolution is too high for the monitor.

PowerMac running Leopard wakes up but the Apple display doesn't

I installed Leopard 10.5.1 on my old Dual G4 MDD (2x867MHZ). My monitor is an Apple Display 20". Whenever the system goes to sleep and I try to resume, the computer comes up, but not the display, which remains in suspended mode. The computer is fully functional since I can VNC into it from another Mac. I can't seem to find a solution for this problem online. I already reset the PRAM and the PMU, and I am running out of options. The computer has an airport card but no other expansion card or any attached peripherals. It used to behave properly with Tiger, therefore I think the problem seems related to the Leopard install. Any hint, or indication that this is a known issue, would be greatly appreciated.

Hi! Sleep problems are common with Leopard. I can set my monitor only to go to sleep and it may wake up fine for several days and then not. It seems worse since the 10.5.1 update. I may just use a screen saver and not let the monitor sleep. Tom

Imac air powers up but no display. Apple light is on; laptop is warm on bottom. No screen and no ability to turn off.

I turned off my iMac Air last night as normal and had it hooked to the power charger because the battery indicator was low. This morning I pressed the Power button and nothing. I pressed a couple more times and I heard the start-up chime. The Apple insignia is lit; the bottom of the computer is warm. But no display and I can't seem to turn the laptop off. I've tried hitting the power button several times but nothing happens. I'm stuck. Help please. Thanks, John

So I waited a couple of hours with the Macbook Air unplugged. After two hours still noticed the Apple logo was "on" and the bottom of the laptop was warm. Pushed the power button a couple of times and the machine turned off. I pressed the power button again and heard the startup chime. I did this while holding down Option-Command-"R"-'P" (no easy task). The screen came on, very fuzzy at first but the cleared up. Wanted to know if I wanted to reinstall the OS, restore a backup or just restart. I took the simplest approach and restarted. The system rebooted fine. The display is back to where it was before. Needless to say, I immediately backed everything up to iCloud just in case this happens again.
Anyone have any suggestions or advice? Thanks, Papajohn-Philly

Apple Display doesn't shut off with new Mini

I have a brand new 2009 Mini hooked up to my 23" Apple Cinema HD display.
When I shut down the Mini, the power on the display does not power down.
I used to have this same display hooked up with the same mini DVI to DVI connector hooked up to my late 2006 MacBook. The display used to shut down when I shut down the MacBook.
There is absolutely nothing different in my setup between the MacBook and the new Mini as far as connections and cables as I'm using the same cables.
Is anyones display powering off with their new Mini?
I wouldn't think that the mini DVI out would be any different on the MacBook as compared to the new Mini. But apparently there is unless I'm missing something.
I don't really want to live with this as all of my computers shut down automatically at night using the Energy Saver control panel. With the new Mini, the display remains on all night.
Maybe I should have bought a new MacBook Pro 13 to replace my older White MacBook 13.
Ideas? Suggestions?

I would hate to say that this might be an upgrade issue with recent updates.. I 'used' to be able to power off the monitor (touch the switch on the side and the light goes off) but no longer able to.
And to confuse the issue, the 23" ACD power switch is now acting like the Mac Pro's power switch.. While the Mac Pro is running a lengthy process, I'll often turn off the monitor if I am away for a few hours but now, when I touch the ACD power button, the Mac Pro responds with a "shut down, sleep or log off" kind of query.. Well that is certainly new to me..
Does this happen to yours as well?

Dropped 12" powerbook - HD fine, powers up but display doesn't come on

I'm trying to fix a dropped 12" powerbook. The battery corner took the impact. I've taken it apart and removed the HD which was fine and backed that up. When I turn on the powerbook it seems to power up fine, but the display doesn't turn on. Though it's possible that there's power but something earlier in the boot sequence is broken and is stopping it booting. Any suggestions as to things to try?
Also, there's a DVD in the slot drive, and ideas on how to get that out?

m...mac,
You may wish to head over to the Powerbook G4 forums for more specific help; good luck.

Apple Store said my display doesn't work but offered no solutions.

Just got back from the Apple Store. They confirmed my iPad is fine but the display doesn't work. It's black. Their only option was to pay $300 for a new iPad. Mine is only 88 days out of warranty and I took it in the store once already for the display issue that led to its ultimate demise. To talk to anyone else is $20. I refuse to pay more for a product that has shown itself to be unreliable. What's the next step? I truly feel wronged. iPad is in perfect physical condition.

I took it in in May of last year. The screen has black bars flash, the screen goes black for a moment, and then it comes back on. It can be days between the issue. When I took it in, it didn't do it. I had to wait forever even with an appointment. I didn't want to take it back in even though it has been having the issue all along. There was no way of knowing when it would happen. It finally flashed and never came back on.

My macbook pro suddenly turn off and now when I turn it on the display doesn't work but it is on!

Hello everyone,
My macbook pro 15" suddenly turned off. Now i tried several time to switch it on and seems it is working but the display doesn't function or there are many wired pictures coming up sometimes.
can anyone please help me with this issue?
Thanks

Welcome to the Apple Support Communities
Your Mac can't find any bootable partition.
1. Insert the Mac OS X DVD that came with the Mac and press C key while your Mac is starting.
2. Select Utilities > Disk Utility, choose Macintosh HD in the sidebar and repair the disk. If it doesn't work, take the Mac to an Apple Store.
Also, open  > Startup Disk, select Macintosh HD and restart. Maybe your Mac has forgotten the startup partition

TS1453 Apple TV doesn't show up in my iTunes. I've done all the troubleshooting steps, updated all software, restarted Apple TV, wireless router and computer. Devices doesn't show up at all in my sidebar.Apple TV doesn't show up in preferences

Help. My Apple TV won't sync with my computer. I've done all the troubleshooting tips, but Apple TV doesn't show up in my Preferences under devices.
2. Reconnect Apple TV to iTunes.
Choose iTunes > Preferences (Mac) or Edit > Preferences (Windows), click Apple TV, and make sure "Look for Apple TVs" is selected.
I see no option to select "look for Apple TV's" in Preferences, and there is no device list at all in my sidebar.
3. If Firewall is on in Mac OS X (in the Sharing pane of System Preferences), make sure iTunes Music Sharing is selected.
There is no option to select iTunes Music Sharing in my System Preferences - see screenshot
I've updated all software, restarted Apple TV, my wireless router, and my computer. Both my computer and the Apple TV are connected to the same wireless network and both are operating properly. They just wont connect to each other.
Does anyone have any suggestions?

FIRSTLY: bookmark following for further reference (it describes basic setup, both to link for syncing and to stream - from any computer.)
Apple TV (1st generation): Differences between syncing and streaming" )
Now as to your problem: If you check under "Computers" in the "Settings" menu you will most likely see the name of your iTunes library Greyed out. IF that's the case, you'll basically need to re-setup your ATV., you can do so as follows (instructions are intentionally over described, but basically your disconnecting then reconnecting your ATV1. Downside (which seems to come with all methods is that you'll have to resync all your media)
**A (not ideal but effective solution)
If ATV 1 had been working but suddenly 'disappeared" from iTunes sidebar
The following solution will almost surely work to regain your ability to Sync:
QUIT iTunes
Select "Computers" from "Settings" Menu.
Select your "greyed out" iTunes library.
This will bring up a window named "Disconnect from iTunes"
You're now given the choice to Cancel, or disconnect. WITH THE WARNING that if you disconnect any content synced with iTunes, will be erased. (in fact it will be removed from your ATV but not your computer)
Assuming ALL of your media IS on your computer, Go ahead and disconnect.
Follow instructions in the Apple doc above about setting up your ATV as a paired computer.
After you ATV gen1 reappears in the sidebar. Reset all your desired syncing preferences,
Begin syncing.
All will be fine again, (at least till the next time this occurs.) I've had to do this twice this year.
ALTERNATELY:
SHARING (a QUICKER, less destructive TEMPORARY solution (if you just want to play your media now)
You CAN set your computer to Share by following instructions in the same doc under the heading:
"How to connect to a shared computer"
HOWEVER, this will not allow you to sync info.
I've read alternate solutions on this board, one involved changing the name of your iTunes Library etc... you may wish to try this first (if it applies) https://discussions.apple.com/message/17943841?ac_cid=142432#17943841
What I'd like to know: What causes this problem... I'm suspecting iTunes updates, or any iTunes database issues or crashes. Or maybe too many visitors connecting to your other Apple devices (ATV 2 for example) or heck the weather in Guatemala...

HT201177 switching to multiple displays via i-mac and apple tv works great in video but the audio doesn't switch over.

When I switch to multiple displays the video transfers perfectly through my Apple TV but the audio doesn't come through unless I turn the volume all the way up to it's maximum level, and at that, it's hardly discernible.

Try resetting the SMC and PRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
However, I suspect you zapped the Mini, maybe the lower voltage part since you siad the fan works.
The power surge could have went into HDMI and damaged the TV.
Make an appointment at the Genius Bar of an Apple store.

Bring it to an Apple store or AASP. Power down by holding the power button down.

I have a ibook that powers up but has no display, is it an easy fix? how much will it cost?

I have a ibook that powers up but has no display, is it an easy fix? how much would it cost to fix

Hi,
Can the sounds of an active hard drive be heard at some point (indicating a normal startup)?
There is a problem with the graphics processing unit (GPU) and its ball grid array (BGA) on some iBook computers, leading to similar symptoms. Reflowing (resoldering) the BGA is a work for specialists, and is going to be expensive. A web search will return a number of more or less realistic alternative attempts to solve the issue. Outside pressure applied to the affected area has sometimes been used for troubleshooting, or even as a temporary "solution".
It is of course possible that the iBook in question has a completely different fault, such as a broken display cable.

Q:-
How can I remove my very old Apple ID from my Iphone 4S. The old ID is still staying on my mobile but that email doesn't exist anymore. I cant rest my mobile as everytime i tried it asks ID password which I don't remember.

Hello mushysun,
Thanks for using Apple Support Communities.
If you did not sign out of your Apple ID on your iPhone before creating a new one, then you will need to sign back in with your previous Apple ID and then sign out. If you do not remember your password and do not have access to the email account, then you can reset your password by using the security questions.
If you forgot your Apple ID password - Apple Support
Have a great weekend,
