IMac G5 monitor problem blue tinge on whole screen

I have a video display problem. I saw flashing and image tearing and then things settled down with everything having a bluish color added to it. I connected an external monitor and that display has normal colors. Does this indicate that the problem is with the computer's video display or could it be some cheaper component that has the problem? Since the computer is over 4 years old, if the repair is expensive, I'm inclined to put the money into a new computer.

Is there any difference if the second display is NOT connected (assuming you normally use them together with monitor spanning)?
If it's +late 2004+, it would be this model

(or one of the other configs in this lineup). You can open the back on these iMac models using Apple-provided instructions.

The one for Inverter may be most relevant, since the inverter provides power to the LCD backlighting lamps. So you might look inside to make sure there is not accumulated dust or any other obvious problem with things like internal cable connections. Other than that, I can't think of anything else to try.

Display problem - blue tinge, low res

My first gen 20" intel imac has an odd display problem.
The screen has a light blue tinge to it which show up particularly clearly in finder windows which i have set to display white. I've played around with brightness/contrast settings as well as colour calibration but to no avail.
This problem started a few months ago when it would periodically flick between being normal and this blue tinge. For the last few weeks the blue tinge is all I get.
The other symptom seems to be a reduction in resolution in 'blue tinge mode' which is particularly noticeable when watching movies.
Does anyone out there have any ideas?

does this problem occur on external screen?

IMac display monitor problems, left side darkens and flickers

I have an iMac with 2.7 GHz Intel Core i5, 16 GB 1333 MHz DDR3, AMD Radeon HD 6770M 512 MB running Mac OS X Lion 10.7.5 (11G63). The last year the left side of the monitor was flickering intermittingly. I didnt think much of it. Then in July, one big flicker caused the left side of the screen to darken slightly. Fortunately, my AppleCare was still in effect,. I contacted Apple and they had me zap the PRAM and also reboot into Recovery mode. The darkness was still apparent. So I took it to an authorized dealer and they fixed the display. Now tonight, one big flicker happened and I noticed that the left side had darkened a little again. I zapped the PRAM and it seems to be ok now, but I'm afraid that the same thing will soon happen. And of course the AppleCare has expired finally. Has anyone encountered this? I have four external hard drives on a shelf right next to the display. This sounds silly, but could they be affecting the display in any way? I moved them a few feet below where they were, hoping that they werent the cause of the problem.
Any advice would be most welcome.
Thanks!

had zapped pram not helped then I would had said that the lcd panel itself was close to the end of it's life and replacement would be required but since it did then I have no real cause to believe the issue would come back

Imac share monitor problem

My wife has an iMac G3-266, tray loading Fruit model with a bad monitor (flyback transformer problem). I have a multiple scan 15av display I was using on my G3 233 beige desktop computer that I have hooked up the imac and it works just fine in this mode. I don't use my G3 much anymore because I also have an iMac G5 that I use most of the time but when I want to use my G3 for something, it is a real pain to switch the monitor cable from the iMac to the G3 and back again. A while back I had bought some 15 pin monitor cables and a manual data switch box so I could just switch from one to the other but if I try to use that setup the monitor setting go bad. The colors are off, the screen is blurry and no matter how you try to adjust it won't work. If I disconnect the setup and try to hook back up the imac, it takes several reboots before the monitor goes back to normal settings. It is a real mess. Any ideas why this is not working? From what I have read on the internet, I should be able to share the monitor but obviously I cannot. Thanks for the help.
Dave

The switch box is probably not passing all signals.
Does this monitor use a VGA connector? Do you have an Apple video to VGA adapter on the iMac's internal video port, like this one?

If so, you should get a separate VGA display for the two computers. If the monitor supports it, the video on a tray-loader can be set as high as 1600x1200. I got a 21-inch CRT at a computer surplus store for around $100, and that was about 3 years ago. They were giving away VGA 15-inch displays.

Help! iMac monitor problem

I was online downloading and reading emails when all of a sudden, long pixels the length of my screen and in varying widths in various colors appeared on my screen obscuring the desktop. When I move my mouse, the pointer became scrambled and whereever I move my mouse over to, the image under it gets scrambled with glitchy pixelated graphics. I was downloading emails at the time so I thought perhaps its some kind of virus but I hadn't opened any email attachments. I quickly forced my computer to shutdown, holding down the power button and restarted. Same thing happens, the whole screen has the long bars with various widths, looking glitched. I put in an OS X install disk and restarted from that, and it appears to be ok while starting up from it which lead me to believe its a software/hard disk problem. But after I re-installed OS X and restarted again to read the system software off the hard disk, the pixelation came back. I couldn't get to my desktop using OS X install disk so I had to restart using the original system 9 disk (no screen problems here as well) that came with my iMac for it will allow me to go in back up some of my files from desktop first because it seems like I would have to re-initialize my hard disk and re-install everything. Anyone have any insight on this?

okie dokie...now i'm really scratchin' my head on this one: since i last posted, i just left the computer alone to rest and just recently i tried to start up the computer using the OS x system that in the computer already . i got to the white apple screen, (no pixelation, just like normal) and the little pin-wheel thingy spins for like 5 - 10 mins then a black blue screen with a white box with pixelation which i'm thinking is the arrow. when I move the mouse it doesn't move. then i did a force shutdown. when i tried again to start up from the system 9 disk that came with the computer, the start up screen with color bar pops up (no pixelation, as normal), then as the color bar is almost filled, then comes a black/blank/dead screen. What do you guys think it is now?
I guess the only thing i can do now because I can't see properly what's on the screen, is take the harddrive out and hook it as an external drive to get the files I need out of it. does anyone know if its possible with these harddrives?

IMac CRT monitor has "the blues" -literally-how to repair? Or should I?

This week I tried to upgrade my 6 yr old iMac (purchased Jan 2000,350mhz & 64 MB, slot loading CD drive). My nephew helped me to put in a memory card (it's now 192 MB) and we successfully installed OS 10.2. My goal was to upgrade so that I could use DSL and network with my new Powerbook G4. After restarting once and verifying that OS 10.2 was working properly, we shut the iMac down and set to work connecting the DSL modem, and setting up the wireless connection on the Powerbook. All went well until I powered up the iMac; I got no chime with a completely black screen. I shut the power down, restarted and got a chime and a screen with only dark blue & black as the colors. OS 10.2 seems to be working just fine, and I successfully connected to the DSL network through the Ethernet port, and even set up the email account with the server! I can surf the web, but only in blue & black! I tried resetting the monitor on the control panels, but can only reset brightness, all colors appear as dark blue!! In the course of the evening we also once had only red & black and once only yellow & black. But now it has settled in to all dark blue & black on screen. I called a local Apple technician, and he said that it was most likely the video card on the logic board, and that it would cost about $300-400 to repair it. Also that the monitor problem was most likely in no way connected to the memory & OS upgrade (which seems correct as OS 10.2 is still working and we can use the DSL connection). I am really wondering if it is worth it to repair this iMac, considering its age and speed. Any suggestions greatly appreciated!

Sure :
Download the widget from :
http://www.apple.com/downloads/dashboard/webcams/mirror.html
Install it. When you hear the whine, hit the F12 key, if the mirror widget does not appear click on + to find it and launch. This will immediatly stop the CPU whistle, and switch on the green web cam light.
Then close the mirror widget (x on the left top of the windows) and rehit the F12.
You should be done with the whine unless you restart your machine

IMac g4 1.25mhz monitor problem

I have an iMac G4 1.25mhz. The power supply died. I replaced it, and the boot tone plays, but the monitor is black. No power light on monitor either. Help!

I have been reading and researching, and I noticed that the solution to iMac G4 monitor dark problem is too often to plug in an external monitor. Most of us iMac owners can afford a "better" computer, but would rather have the ORIGINAL iMac 100% working. Display and all.
My problem is (I believe) the inverter assembly, or the video cable. From what I've read, the inverter could just go out, or in the re-assembly process the video cable could very possibly get pinched or otherwise damaged. The video cable is VERY delicate.
I don't know how to tell which is the problem.

Is there a fix for my imac monitor burning highlights into blue shapes on my screen?

Whenever I leave an image or window open on my imac for longer than 5 minutes the white boxes or white in the images burn a blue shape onto my screen. It is apparent in every program and finder, but overly so in photoshop. Is there a fix for this or do I need to take my computer in? I've tried changing my display settings to AdobeRGB 1998 and turning down the brightness but neither fixed it.

Image persistence on LCDs is not permanent like screen burn on CRTs.
Have a look at > Avoiding image persistence on Apple LCD displays
Personally I use a Hot Corner to Sleep my displays when I get up or when I'm not looking something. I also have the Display Sleep timer set to 10 minutes, just in case I get up and forget to use the Hot Corner.

Monitor flickering blue? (Not from Display)

My Macbook '09's monitor is flickering blue. It's usually only the top right corner, 2x1", that's tinted blue. Sometimes it'll extend over to 4", sometimes it'll fill the whole screen (it usually does this when I push the monitor all the way back, but not always), and sometimes it'll just flicker randomly. (it does this while I'm holding it, without fail). Control of brightness isn't effected. I've tried taking a screen cap of it, and I checked it on a separate computer. There wasn't any blue, so It's definitely a hardware problem. I just have 2 questions.
1. Do you think it can be fixed without replacing the screen?
2. Do you think this is going to lead to other problems, such as the monitor stops working?

Hi Brett,
Thanks for your response, I'm on an iMac not Macbook but checked your link, All my software is up to date and there is no updates for the Asus and nothing for the mini dislayport to display port cable.
Everything works as it should via display port if i run bootcamp into windows 7 just not from OS X so would seem like a Mac Graphics driver issue perhaps??
I was hoping it would be a glitch that would correct itself by unplugging the cables or resetting the P Ram but no such luck so i am open to any other sugestions.
The iMac can see the Asus at all times just doesn't seem to send the signal to the Asus?
I would be happy to supply any logs that may shed some light on this issue.
Kind Regards
Mark

IMac external monitor not working after lion upgrade

Hi,
I have had an external monitor hooked up to my 09' imac for over a year now. I upgraded to Lion and ever since then it hasnt worked but one other random time when I moved and hooked everything back up. Im very tech savy, but this just doesnt make sense. Have combed google to find a solution. I have a Samsung 22in moniter and all the blue power button does is blinks at me. I am using a miniDisplay to DVI connection.
Does anyone have any suggestions other than resetting the ram?

I guess it's possible you've got some kind of hardware problem.... but not likley given it started with you installed your OS.
Here's a few things to try:
1. see if you can borrow another monitor just to be sure your monitor isn't the problem.
2. in System Prefs, and the Displays pane, click on the Detect Displays, then then the Gather Displays. If you get two diffenet display panes, that would lead me to think it's a monitor problem.
3. Lastly, disconnect your 2nd display, and restart. Then Shutdown, reconnect it, and see if that helps.
and of course..
4. make sure that all of your connections and adaptors are tight.

Monitor has Red Tinge

Hi
Basically moved my G4 Tower to my new house, and when plugged monitor back in I've got this red tinge to the whole screen, I have reset and cleaned the Video card but still have the same problem, does anyone have any ideas what I can do to sort this out or is something screwed?
Thanks Nick

If this monitor connects with a VGA cable, carefully examine all connections for bent pins, then be certain all plugs are firmly inserted into their jacks.
This is not a "fools errand". The pins for red and red ground are at one end of the connector, and a connector beginning to slip out of place may exhibit exactly this problem.

When I had a PC I simply took the wire going to my monitor and connected to my big screen TV to watch Netflix movies...How do I take them from my IMAC and connect them to my TV now?

This could be problematic.
It will depend on what model of iMac you have.
You may want to post machine info.
blue apple > about this mac > more info button. Click on the hardware line. It has a little triangle in front of the work hardware.
Leave out the serial number.
Example:
Machine Name: iMac
Machine Model: PowerMac4,1
CPU Type: PowerPC 750 (33.11)
Number Of CPUs: 1
CPU Speed: 600 MHz
L2 Cache (per CPU): 256 KB
Memory: 768 MB
Bus Speed: 100 MHz
Boot ROM Version: 4.1.9f1
Most of the iMac's have sometype of video output port on the back. You will problably need a converter.
The 'hollywood' industry has been making it more difficult to get video out over time to prevent copying.

Possibly mundane Mini-DVI to VGA into an external monitor problem

Hi,
I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
Thanks if you can help!
Jack

You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
Joy joy hallelujah.
Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
Hope that helps.

Monitor goes blue on startup

Yesterday we had a power failure. All our computers came back fine, except one - MINE! When I went to restart, after saying "Starting Mac OS X", my monitor goes blue. First I ran Apple Hardware Test and it states, "no hardware problems detected". I was told to start up from the cd/dvd for Tiger and then run Repair Permissions from Disk Utility. I held down the "c" key and started from the cd/dvd for Tiger and it took me through installation. After performing the installation, I was prompted to re-start and it did the same thing (blue monitor). Any ideas? Please help!!!
G4 Mac OS X (10.4)

Many Macs, especially G4s, will not boot after a power failure. The solution is to reset the PMU. In your case it's trying to boot but has a problem.
Try a PMU reset. See Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial
When you are troubleshooting a Mac, disconnect all external devices except the kbd, mouse & monitor.

My iMac (2007) keeps shutting off when in Full Screen mode (DVD, iTunes Visualizer, etc.) This only happens when I have an external monitor hooked up HDMI.

Try using another connection such as VGA or DVI to see if the problem repeats itself.
