Power Mac G4 Display Problem

I own a Power Mac G4 Digital Audio 733MHz model, and an Apple Flat Panel monitor.
The monitor connects using ADC. Sometimes when I boot my Power Mac the power light appears on the display, but the display screen does not turn on. Rebooting the Power Mac will make the display come back to life.
A while back someone in the Apple Forums suggested replacing the PRAM battery.
I tested the PRAM battery, and it is fine.
I opened up the Power Mac case, and see that the AGP card is properly seated.
What would most likely be the problem? Would it be the display, the video card, or the logic board?
Thanks!

Just an update, I tried a different LCD Display with a VGA connector and it works fine.
It must be the Apple Display.

Power Mac G4 sleep problem

Hello!
My G4 (mdd) won't go to sleep anymore. Neither on its own via energy saver nor when you press the power button or select sleep in the apple menu. Does anyone know what to do?
I already unplugged my USB devices, didn't help. Then I trashed my energy saver and bluetooth preferences and reset PRAM by pressing <commandoption+PR> at startup, no luck. I read all the previous posts about this issue and did everything they said, but it didn't help.
maybe someone has an additional suggestion.
Thank you!

A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
Some, in these forums, have had luck fixing sleep issues downloading the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.3.9 combo update. Others here would use the one for their version.
Cheers!

Power Mac and Display - power surge?

I hope someone can help even if it's common sense...
I had my Power Mac on for a while and all of a sudden a pop/click sounded and the power went off for the apple mac and the display/monitor.
Neither turned back on and there's no sign of power so I assumed the fuses need changing; however I replaced them and both the display and mac unit still will not turn on or show any power.
Does anyone have any suggestions what else could be wrong? Since it's affecting both display and unit, I can only assume it's power-related. Much appreciated, thanks.
Power Mac G5 Mac OS X (10.4) Using Logic primarily with plug-ins - no internet connection.

Hi, and a Warm Welcome to Apple Discussions and the Power Mac G5 Forum!
Assuming the display is powered by the G5 video card and therefore by the G5 Power Supply Unit - and that you have taken the appropriate steps to ensure that the mains power up to the G5 is working ok - when the mains power to the G5 is first connected and turned on, there is usually a 'relay-click' sound at the back of the G5.
If you don't hear this, and you have a "Late 2005" dual-core G5
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
then it's possibly the 'Pop of Death' in the Power Supply Unit which would qualify under this recall, sorry, repair extension
http://www.apple.com/support/powermac/powersupply/repairextension/
If you do hear the relay-click, then you could try a PMU/SMU reset
http://docs.info.apple.com/article.html?artnum=300341
If still no go and you have another, earlier G5 which is not covered by the repair extension above, it sounds like a case for AppleCare, if you have it, or the repair shop. Sorry.
Please post again if you have any questions. Good Luck.

Power Mac G4 MDD problems with Hardware test Memory errors

I have been troubleshooting slowness and unexplained lockups on my Power Mac G4 MDD. I've had the system since 2002. I tried to run hardware test (the disk that came with my system), and I get an error message at startup:
Invalid Memory Access at %SRRO: 00034870
%SRR1: 00003030
I run mac-boot, and get another memory error
Invalid Memory Access at:
%SRRO: 056106dc
%SRR1: 00003030
Does this mean my memory has gone bad? I don't get any other screens for testing hardware.
The lockups are varied, but many seem to deal with Safari. I have also repaired disk permissions and repaired disk. I then get security error messages when I restart, and I choose to fix them, and things are fine for a while, but then it slows down some and starts locking up again.
Thanks for any suggestions,
Marbot61

Hi Marbot61,
You might be interested in the thread "error when booting from AHT CD" on this forum. Since four different users have had the same error message in two days, perhaps ram chips are actually ok, and there is something else going on with the AHT CD boot process.

Dual 2.3 Power Mac G5 sleeping problem

For sometime now my G5 has had a sleeping problem. I use evetv 500 to record tv shows. Most times I have been on the computer say 5 to 6 pm. I'll have it set to record at 7. The G5 will start up and record no problem, but the monitor will not go back to sleep, the whole system is almost locked up . I have found that the computer clock will be stuck at the time I let it sleep. If I move the mouse the clock will update, and the system will sleep.
Thanks for any help
Dual 2.3 G5 PowerMac Mac OS X (10.4.9)

Hi,
I've experienced something similar a bit now and then. The most recent occurense of this was just a few minutes ago. Last thursday (june 21st), I set my Mac to record one show at 21.00 and one recording at 18.00 (every weekday on the 18.00 one), both recordings are one hour each. The ordinary "sleep when idle" function doesnt seem to work properly but I still set it at 15 minutes plus a scheduled sleep at 22.08. Now when just I came home the Mac was on though it shouldnt be. iStat in Dashboard gave me these figures:
Uptime 0d 4h 22min, up since 8.35 june 21
The only reaction I got when I tried to check the sleepsettings was a message telling me that the computer was scheduled to go to sleep in 9mins 55sec's and the System Preferences panel just bounced in the dock, every app that I tried to start just bounced in the dock. When I tried to restart it I got a message, after a while, telling me that Eyetv was keeping my Mac from going to sleep and trying to force quit it didn't seem to make much change. I finally turned the Mac off by pressing the powerbutton on the front.
I got the 18.00 recording on thursday but not on friday and no 21.00 recording from thursday. I thought the scheduled sleep would override the other setting...

Mac Firefox display problem

This problem is only on Firefox for Macintosh - but I'm not
sure what's
causing it, and it's difficult to troubleshoot without easy
access to a
Mac - so any help much appreciated.
On the Home page of the site, in the center of the page,
there's a
light-blue box consisting of a form with a table nested in
it. They are both
in turn nested in a table, and another table. (What can I say
- I have
nesting instincts :-)).
The screenshot I was sent shows the light-blue box shifted
over to the right
so that it overlaps the content to its right. Here's the
screenshot:

Anybody know what I can do to fix that?

Mac mini display problems

My Mac mini (bought in early 2011) has recently started having sync problems with my viewsonic monitor. It used to work fine. Have upgraded to mountain lion and mavericks hoping to solve the problem but it persists. I get snow and then blank screen. This happens randomly I never know when the screen is going to go white on me.

What connection configuration are you using...?
HDMI to HDMI
HDMI to DVI
Mini DisplayPort to HDMI
Mini DisplayPort to DVI
Mini DisplayPort to VGA
Have to tried resetting the NVRAM...? see > About NVRAM and PRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

Please help me! - really weird mac mini display problem.

Ok this is just too WEIRD.
i have a brand new 1.42ghz mini (512mb ram and wireless) with a sony SDM-HS75 LCD. This is an analogue LCD and im using the supplied apple VGA adaptor.
before i continue i will say that i have hooked up the lcd to numerous other macs and the screen and cable are fine. i have no dimmer switches on my lighting, i have no objects placed on the mini (like a cell phone etc)
when i first set up my mini the video output was murky and grey and noisy across the screen. Then i discovered the setup utility on the CD that came with the sony screen. i ran it (it displays a grid calibration thing) and discovered the "phase" adjustment on the sony's on screen menu. i managed to adjust out the fuziness and noise and the image quality was then perfect.
heres where it gets weird. the point at which the monitor is in phase with the video signal shifts around all the time! i mean - i get the phase set at say 43 out of 100 on the adjustment scale and the next time i restart i need to shift it to 73 to get rid of the blur and the noise on the display.
Also, the using airport affects the display and knocks it out of phase - i dont use wireless but if i activate it i can see a difference instantly.
this is really strange and i cant see a solution.

Is this a new-ish LCD? Many newer LCDs will have an auto adjust option or button to set the phase and fine tuning for you so you don't have to do it yourself.

Power Mac G4 (AGP) Problems booting up.

When I turn on my Mac it starts normally but when it gets to the apple logo screen it stays there for about 5 minutes then transitions into a blue screen where I can see my mouse in the upper left hand corner but not move it. My Mac never gets past the blue screen. I'm new to Macs, so any input would be helpful.
Thanks,

Hi-
Try starting in Safe Mode. Hold the Shift key while starting. If successfully booted to Safe mode, restart, and the machine should start normally.
If not, there are possible Startup or Login item problems.
Troubleshooting Startup and Login Items
The startup problem could also be caused by directory problems on the hard drive. Boot to the OS X install disc (hold C while starting) and open Disk Utility in the Menu bar in the pane after the language selection pane. In Disk Utility, select your Startup drive, and select "Repair Disk".

Power Mac G5- Display Issue

PowerMac G5 running OS 10.5.8 with 20" cinema display.
Changed the inverter board in monitor due to one long, two short flashes. No more flashing light.
BUT...
Screen resolution is funky. Have res to highest setting and MOST things look fine except that when I am on the desktop the icons and fonts are too large, gey bar on top of desktop (along with text) is too big. Checked the settings for desktop icon size, Universal access, etc. etc and everything seems to be in order.
HOWEVER...
I dove in last night and reinstalled the OS. During the reinstall the grey bar on top iof desktop (along with text) is fine and the windows that open are of the right size.
I am dumbfounded...any ideas?
JLG

Let's try to fix the other account.
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions.
Move these files to the Desktop for now...
/Users/YourUserName/Library/Preferences/ByHost/com.apple.HIToolbox.<12digitHexNu mber>.plist
/Users/YourUserName/Library/Preferences/.GlobalPreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/<yourname>/Library/Preferences/ com.apple.systemuiserver.plist
/Users/<yourname>/Library/Preferences/ByHost/com.apple.systemuiserver.xxx.plist
where 'xxx' is a 12 digit (hexadecimal) numeric string.
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

Power Mac G5 Display Recomendations

I've just purchased a G5 1.8ghz from a friend and am looking for a good quality monitor to use with it as my old pc one is just so poor. I'm no super designer but am looking to edit HDTV footage, photos and also some photoshop editing. Budget is c £300 ($500). I'm not sure what monitor the G5 originally came with and can you get these anywhere online. Thanks

The G5 never came with a monitor, so there's nothing to look for in that regard.
I'd recommend looking at Dell's 2007WFP 20" flat panel. The panels are pretty much the same panel as what's in the Apple Cinema Displays, but the Dell costs much less (and has a better warranty).
This display is £302.27 right now at the Dell Home store. http://accessories.euro.dell.com/sna/productdetail.aspx?c=uk&l=en&s=dhs&cs=ukdhs 1&sku=59233
I have Dell's 2405FPW and absolutely love it.

Power Mac - G4 QuickSilver and dial-up problem..

Hi all, first post here please excuse my naiviety!
As well as owning a Macbook I've been helping a friend out with their 9-10 yr old G4 Power Mac. The problem started with it not being able to power on so I tried resetting CUDA etc; that didn't work so I sourced a replacement Power Mac (power supply being impossible to replace).
All went well, swapped the HD out of his duff M5183 and put it into the newer QuickSilver. Booted-up fine and apart from running quicker it looked like his old Mac. When he tried dial-up (he can't get BB) he kept getting a no dial tone error. So I had a fiddle and managed to get a tone... however when the 0845 number was dialled all you get is a beep....beep....beep noise like the line's engaged or unobtainable. I managed to inadvertently wipe his ISP settings so tried another ISP (called freeisp, 0844 7110059) - still get the same reply on the line with this.
Question is, I'm guessing the modem on the QuickSilver is different to that on the M5183? Do I need to install drivers? The modem seems to dial out okay so I'm a bit confused.
Any help gratefully rec'd... he hasn't been able to get online for some time now.
Ta, HB

According to this article:
Apple USB Modem: Frequently asked questions (FAQ)
Sep 15, 2008 ... You can use an Apple USB modem with any
Mac computer capable of running Mac OS X 10.4.3 or later.
You MUST have Mac OS X 10.4.3 or later...
http://support.apple.com/kb/HT3152
Even email and sparse internet activity would be slow.
Still, that invites further research to be sure; and also to
check what update or upgrade the computer hardware
may need to be ready for the demands of the OS on it.
Hardware upgrades in RAM chip & hard disk drives are
the primary ones for basic physical upgrade; and then
the OS X. And Panther is not really adequate today...
Tiger has support; Panther has increasingly more wants
that are not met and does not see updates. It's rather old.
You should check into the available "retail boxed" Tiger
full installer sets that have previously been sold to people
and now those persons have upgraded to Leopard 10.5.
These should be priced less than online reseller's retail.
In some places, the universal install DVD set is not costly
once you get away from the retail demand. Amazon is a
source of retail goods; ebay is a place to find retail prices.
Individuals, whose goods you would have to be aware of
before buying (or if given a retail box Tiger installer DVD,
be informed as to what you really had.) Be sure it is NOT a
version made for a single model or series of computer,
since those would only work in that one model line.
Without access to DSL or faster cable broadband, getting
all the update bits for the system would be prohibitive; no
matter the version of OSX (or any OS) it would be too slow.
You may be able to get copies of the correct downloads
from persons you know; but you have to be sure they are
the correct ones, and not versions for some other device.
(Some update files are for Intel-based Mac, not PPC-based.)
If you have a portable computer, a list of upgrade downloads
needed (for a needy desktop computer) and a place to go and
experience fast broadband or adequate DSL, the necessary
update files a new OS X installation would require to be up to
date could be gotten; they could be saved to a CD for later use.
The latest security update, all the java updates, the Combo update,
Quicktime, Flash player, Shockwave Player, modern browsers, &
other items are required to bring even Tiger up to today's web
and daily use if going online (or if using applications needing it.)
With a list of needed applications, and/or web sites where the
downloads could be acquired, and getting 'standalone' versions
for later use in a computer later, one can deal with a slow web
access point at home, by going elsewhere to get the essentials.
And to get them with the idea of making a backup archive for
later re-install should that event of necessity occur. The Apple
Support Downloads site has OS X related updates & is search-
able. So knowing file names to do this, that way, is important.
Having the subject computer at the point where high speed
internet is available makes all kinds of sense, to just update
the newer OS X version and make it work correctly.
And the need for this would become painfully clear to even
someone with no credible amount of experience. Anyone
with hopes of getting a task done in their lifetime could see it.
Good luck & happy computing!

Power Mac G4 MDD No video past boot

I was just given a Power Mac G4 MDD and it's been so long since I've worked on a Mac, except for my 8GB iPod Touch, 16GB Verizon iPhone 4, and 16GB iPad 2, I just can't seem to get this thing running.
Problem:
After pressing power button, I get the start up chime and the loading circle at the bottom of the Apple screen then it flashes a blue screen and the display does black and displays input not supported.
I have a 19" wide screen Acer LCD screen connected capable of at least 1440x900
What I've tried:
CMD-OPT-P-R
C
SHIFT
CMD-OPT
CMD-OPT-A-V
CMD-OPT-SHIFT-DELETE
I still have nothing. Any thoughts?
Thanks in advance for the assistance!
