Hi, sorry that I don't know how to post image directly, so you have to click the link to go to the picasa site to see the screen captures.
Am having weird display problem with my Snow Leopard 10.6.1 on Macbook Pro 4,1. It's only in Finder item so far, things are randomly mis-displayed, or wiped out completely. If you see my screen shots you will have a clear idea.
Is this a know problem? I don't even know how to search this problem on the web, or in this forum. I never seen such problem on my iMac with Leopard 10.5.7.
Any solutions will be appreciated. Of course, right now restart seems to be the only solution I have.

he general approach at this time is to ask if you've checked for any problematic fonts (all languages) with Apple's Font Book (look in the Applications folder). Find and remove all duplicates also.
Start there to be sure all fonts that are in play come out with a clean bill of health.
Also, don't hesisate to perform wholesale deletion of old and/or little used fonts - be skeptical of anything that has come from Office 2008, including those related to an Equation Editor installation.

Weird event display problem in week view

Hi. I'm getting a weird display problem in week view. First time this has ever happened.
Some events appear to be missing, but when i double click on where I know the event is supposed to be, a new event is created (as excepted), and the missing events suddenly appear. When i move forward or back by a week, and then return to the week in question, the missing events are gone again. But, I can see the missing events in day view or month view.
Any ideas?

Dean,
Next, try reinstalling the Mac OS X v10.6.2 Update (Combo).
If that is unsuccessful:
1. Use iCal>Export...>for each one of your individual calendars.
2. Delete all but one of your calendars.
3. Create a calendar and name it "Test."
4. Delete the calendar which remained after step #2.
5. Quit iCal.
6. Remove the iCal plist, and drag the iCal plist file to your Desktop.
7. Log out/in or restart.
8. Restart iCal and use iCal>File>Import...for each one of the calendars that you exported in step #1.
9. Delete the "Test" calendar, and any "Home/Work" calendar which was automatically created when you opened iCal in step #8.

Weird icon display problem (9iAS Forms 9.0.4)

Let me start out with the fact that I have setup 6 or 7 systems displaying GIF's as icons in web forms (both Forms 6i and Forms 10g/9.0.4). So I know all about setting the registry.dat, virtual directory for the icons etc. I have setup the environment correctly (unless some fat finger typing has gotten in the way).
When I load a form in a web browser and I watch the status bar on the bottom of the broweser ( IE6 or IE7) I can see that it loads the GIF's (fortunately my server is just slow enought that I see the "loading .....xyz.gif" statements for my GIF icons.
What happens is that none of the icons display on the buttons. Of course when I run the form in the IDE the icons display as expected.
Has anyone run into this problem before and if what was the solution?
TIA,

1. The image files cannot be found or are not accessible. Just because you see something on the client that says "Loading..." does not necessarily mean it was found. Check the HTTP Server error_log. If you see HTTP 404 errors you have an access or virtual path problem.
Answer: No HTTP 404 Errors (no errors at all). FYI, Files are located in D:\icons (W2K server) and the Security is set to "Everyone" with Full Access/Control. The AS has "D:\icons" mapped to /icons and Registry.dat has the path set to /icons.
2. You are using an image format that isn't supported. For example, Forms supports GIF files, but not GIF files with transparent backgrounds. Also, Forms does not support most of the compression formats associated with GIF and JPG. Test with an image that you know will work. For example the OTN Logo on this page. Right click on the image and choose Save Picture As.... or:
http://www.oracle.com/admin/images/otn/otn_logo_small.gif
Actually, you should be able to simply put the entire URL above into the image filename field on the Property Palette for any Iconic button large enough to hold it.
I pretty sure this works in 10.1.2, not so sure about 904
Answer: You'll probably say this is not good enough, but the images work in the IDE, therefore I conclude that they should work on the AS (i.e. size and display type are correct/supported). I did not have a button that was big enough for the Oracle logo, hence I did not try it.
3. The image size is too large for the button.
Answer: see answer above.
4. References to images are case sensitive. It is recommended that your image files (in the file system) use all lower case letters, including the extension. The reference in the form should also be lower case.
Answer: all image names in the property pallet are lower case and the actual file names are lower case (as shown in Windows Explorer).
With regard to the other post about icon names ending a list of specific characters, some do and some don't, but ALL my icons are NOT displaying.
Lastly, these exact same icons have worked in the past (who does not reuse icons?).

2x iMac G5: Both Logic Board and Display Problems, Warrenty?

Hello,
Thank you for looking at this topic.
I am Jeroen from The Netherlands and proud owner of several Mac Mini's, iMac's and Macbook's. I have 2times the iMac G5, a beautiful machine, but both not working since 2 months.
I have two times the iMac G5 with iSight, both have logic board and display problems.
The first iMac doenst start at all, black screen, i hear the chime, but nothing happening. After a minute i see one horizantal white stripe but nothing happens.
The second iMac has weird horizantal stripes also, but the computer starts. It gives a finder and questionmark icon. After a while the fans go crazy.
Both these symptons are widely known on the internet. I would like to get this fixed, but prices are crazy. And because this is a common issue I would expect to get this fixed for no costs. I have contacted several Apple resellers but they shown me high prices and bad services. On these forums I've saw people in the USA who get this fixed free of charge.
Does anyone has any advice for me? I'll call apple USA this morning.
Thankyou for ur time.

Welcome to Apple Discussions.
I know of no repair extension authorization which provides for the repair of either computer you describe beyond its original 12 month period of coverage. If either machine is covered by a warranty extension program provided by AppleCare, then the parts, labor or both required to replace the defective components may be offered at no charge to you. Final determination of eligibility is made at the part level by authorized Apple service providers or dealers and by the specific serial number of the machine submitted for service.
Absent a warranty extension, however, it is quite likely that you will have to pay for the repairs is you elect to have them performed.

Odd Display Problems - Solved (& More...)

Earlier today I picked up the weird display problem shown in this thread: http://discussions.apple.com/thread.jspa?threadID=1524985&tstart=30
I went ahead and reinstalled the Leopard Graphics Update and reset the PRAM. Problems seemed to go away. But then I ended up with an even weirder white-on-black display that looked a lot like an xray. So reset the PRAM again. No fix. Then restarted in SAFE mode - all OK, so probably not hardware. Then ran Disk Utility from the Leopard System CD. No probs revealed. Problem (white-on-black) came back on restart. Searched Discussion base and found reference to wrong toggle set in Universal Access System Preference. This was the white-on-black problem and toggling to black-on-white solved it.
Here's the part I don't understand (but like): the machine is much faster than it was. Safari pages load with great speed, apps open faster, etc. It may have been the series of restarts that cleared something, but somewhere in this troubleshooting string things overall got a lot better. Beats me, but like it... YMMV.

I just have some general thoughts. Does it look correct if you connect it to a different monitor? (to find out if the TV / TV connection is the problem) Did you install something in your house that could affect the signal that is being transmitted through the wire? (I highly doubt it) Are you SURE you didn't install / update / change any settings before it stopped working?
The problem you described reminds me a little of the glitchy GTK problems I was having with my Radeon. My problem ended up being related to the open source driver and KMS. Is there another driver or video card you could try? Is your video card getting too hot?

Wierd lines on my display and frequent lock-ups w/ and w/o display problems

When booting I sometimes get weird lines and blocks on my display (the GRAY Apple screen) and then it hangs, other times the computer will boot and run fine for 20-30 minutes and then the display goes wonkers with blocks and lines and the computer does not respond. The only way I can get it to boot is to reset the PRAM by letting it CHIME 3x and then occasionally it will boot without issue and run, while other times I still get the blocks and lines on the display.
When I am able to get it to recover and re-boot after the lock-up and display problems and occasionally the box in the middle asking me to re-boot similar to a kernel panic the OPS gives me the option to REPORT the error and here is the error for others who would know more...
Thank you in advance,
Darren

Anyone know what is causing my problems? I thought it was heat so I downloaded a CPU and FAN temperature monitor and the CPU was getting VERY HOT at first so I then ramped-up the CPU FAN SPEED to maximum - it turns out the CPU FAN was not rotating well at low speed - since then I have cleaned and checked the fans and they all work as they should and blow on high(er) when the CPU temperature is above a certain level.

S.U.
Is there a kb article or something that would illuminate what to look for in these logs, or is it a matter of learning by osmosis?
Both. I am not skilled in reading logs. It is a very technical and time consuming task for the uninitiated (me!) In scanning a log I look for the backtrace and loading dependencies. The first item in the backtrace is usually the roadblock.
Beyond that you can look at the Technical Note TN2063: Understanding and Debugging Kernel Panics
Should make for good bedtime reading. Puts you right to sleep.

My original post, locked by this forum. Display problem related

Hi G5 Gurus,
The display problem first, we all know when screen savers display, a click on the mouse will bring you back to the active desktop, this was how it worked., but now, sometimes a click cause the G5 to sleep!
As for the sleep, I dare not to put it to sleep these days, because I am afriad it may cause a fire by over heating. Sometmes, actually four times in the past few months, my G5 could wake up by itself, followed by a extrem high speed running of the cooling fan, it sounded like a hair dryer running in the same room. Sometimes the sreen could light up, just like real wake up, sometimes, it was black. No clicks the mouse or keyboeard could bring it back to normal, I had to press and hold the power button to turn it off.
This crazy problem happened for the first time last summer, a dead hard disk was the cost. Apple replaced it, but failed to detect the cooling or power or display problem. I was given one month extended free service, but right after its end, the problem was back and happened even more often.
Please let me know if any of you had the same problem and please advise what to do.
100s Gs of thanks.

I have the EXACT same problem. In fact, I could not have described it better myself. What gives? I brought it in to the "genius" bar and they repolaced the power supply free of charge but the problem is still there. I noticed they ordered a new logic board but did not end up replacing it after all. Did you have yours replaced and did it work? Is this a known issue?

Hi La teller,
Thank you for your reply. The 'genius' here in London only replace the dead hard disk, which I belive was a victim of this problem. I was told they couldn't find anything wrong with the power supply or the cooling system.
Now at lest I know I am not the only bad luck guy. Let's wait and see if others are having the same problem. I am not sure if this is a known issue to Apple, even if it is, it may take years before they can offer a recall or free repaire. I noticed that some G5s have already been suffering from power problems and a free repaire was offered.
Thank you again and hope Apple can take our concerns into their consideration soon.

Hello,
I'm also having this problem (fan running, won't come out of sleep), just spoke with an apple care rep. He confirmed my suspition that it was software, not hardware as I have just had the logic board and power supply replaced.
His suggestions were to:
1. Run disk repair from the startup CD
try running OS X from a firewire drive and see if the same behavior happens or
perform and archive and install.
When the fan starts to run like that it means the OS is not communicating with the hardware properly. The OS could be somewhat corrupt if you were having hardware issues beforehand, hence the need for a reinstall. I will be performing an archive and install after the disk repair, I'll let you know if it fixes the problem!

Hi Stopha6,
Thank you for your message. I never imagined it could be a software issue, cos it looked so hardware.
Please keep me updated with your progress.
By the way, as I said in my old posts, a hard disk went dead when this happened for the very first time, how do you read this?
Thank you.

Hi Stopha6,
After reading your reply again, I realized that the system had already been reinstalled. As I said when it happened for the first time, the hard disk died with it, which was replaced, of course with a new OS X, but the same problem is still happening. May this suggest that it is not just a software problem? Thank you. Songyan

The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on. The screen-saver and sleep problem you describe sounds like something that may just happen on accident. But this sounds mostly like a software problem. Try making sure to always quit all non-apple products and see if anything changes.

Thank you, Ag-Nate. I will try as you adivised but I con't think the fans were activeted my intensive CPU using. In most of the cases, the problems happened when the Mac was sleeping, when the minimum CPU were being used.

"The Fans going at full is only because you have an application that is using a lot of cpu power and therefore causing the imac to heat up so it turns the fans on."
That's only partly right. A hard-working process will make the fans run at high speed, of course.
But, the OS is in touch with the firmware of the iMac, telling it how to run the fans, based upon information the OS X kernel is getting about the state of the hardware.
If the firmware loses touch with the OS for some reason, and is not getting instructions on how to run the fan, it will default to running them at full blast, to be on the safe side (and this "full blast" fan mode is way louder than anything you'll generally experience during normal usage, I know from experience).
So it may not be so simple as a hard-working cpu process kicking the fans on.

Hi I have a 20" G5 imac it's about 18 months old and I am having the same problem, It freezes and the fan runs really loud. It's nothing to do with software as my I.T. guy has done a complete re-install. All of our admin people have imacs of differring ages and the flat panels are all OK but every one of the G5s has had a booting problem. Some fell into the recall for replacement logic boards but the one I have at home is the newest and doesn't. I'm waiting for my apple reseller to get back to me, but it looks like it's the logic board and as none of the serial numbers fall into the recall, I'm expecting a big bill. I'm really disappointed as I've been a professional apple user for over 15 years and have grown to expect a certain amount of honesty and integrity from them. Looking at all of the discussion boards and the amount of people complaining of the same problem the logic boards are defective and apple should be replacing these free of charge.

I am having a very similar problem. My G5 imac has already had the logic board replaced from the leaking capacitor problem. 8 mos. later the power supply was replaced under the second recall program when it failed to start up.
It had been working now for almost a year, when about 3 mos. ago I started to experience the sudden dimming effect - if the display was untouched the screen would dim about 30% similar to a laptop in energy save mode. I checked and none of these types of options were set in the pref panes. At the same time I would have the iMac go to sleep after a while from non-use, and then when I tried to wake it it would stir for a few seconds and then go right back to sleep. It took 2-3 attempts to wake it up.
Then last week, as I tried to wake it, it just shut down instead completely. I had to hold the power button down to recycle it to get it to come back to life (3 times).
Today was it - I found what I thought was a sleeping iMac, but it will not power up at all. I opened the back cover and the power supply is working, but I cannot get the board to energize, I reset the PMU, but the #2 LED won't even blink. It is completely dead.
Basically every time I used this computer I held my breath that it would not work. After 2 recalls I still only get 9 mos. out of it? Apple is really starting to show it is like the "big" computer makers, the quality is going right down the tubes.

Ideacentre B320 display problem

I'm suffering from a display problem, and cannot figure if it's a software or hardware issue... I'm on Win7 64bit. Here are the symptoms:
1) For a while now, intermittently the screen would go grey (or some sort of a messed up pattern of rgb pixels) and I would have to power down forcefully. The frequency of this has gone up very much in the recent weeks
2) When the machine freezes, I can still hear the music playing, and Windows continues to do whatever it was doing before
3) Recently (I'm guessing after a Windows update), I wasn't able to boot into normal mode anymore. It would show the Windows splash screen, then before the login screen appears it would just go black and freeze. Leaving it for a long time doesn't lead to recovery
4) To try and fix this, I've updated the ATI driver to the latest version, which didn't work so progressively tried every version between the11.6 and 10.3 (4?) which was the default when the machine was purchased. No luck there. I've also flashed the bios and that didn't help either
5) I can boot into safe mode, so I disabled amdkmdap using sysinternal's autoruns.exe, which meant that I can boot into normal mode, but it woud fall back onto Windows' vga driver (1400x1050 only!)
6) Now, even in the low res mode, almost daily the grey screen freezing would happen and I would have to reboot. Tapping the power button allows the shutdown dialog to come up (I'm guessing), and pressing enter would shut down the machine then.
There's an awful lot of posts on the internet regarding people having issues with ATI HD6450 and similar category cards, some of which sound similar to my case. They too experienced the freezing problem and reverting or upgrading the drivers had no effect (many even reinstalled windows completely). It sounds like though, the problem is software in origin at a guess.
On the other hand, the machine is now 3-4 years old and I could imagine that the GPU or graphics memory might have suffered wear and tear -- emailing Lenovo support took a week to get a response, the only thing they asked was whether my warranty is still active (after that it's been a complete silence) are they usually this terrible?
The last thing is, when the problem first occurred I booted using a linux live CD and it was all fine, at full resolution graphics. I haven't repeated this experiment since it takes quite a while to boot from a CD... but suggested that the hardware is intact. In fact, by messing about with the drivers I was able to boot into Windows normal mode and operate for 1-2 days, after which the grey freeze happened again. I haven't been able to get back into that since.
Here is my question: Is there a way to find out whether it's software or hardware that's at fault? If it turns out to be hardware, what are my options at replacements? The GPU is soldered onto the motherboard, so do I have to replace the whole thing? If it's a software issue, would restoring to factory default state fix this issue, given that an unknown update could cause the same issue at any time... This is the last time I will buy an AIO without removable everything.

Welcome to the Lenovo Community !
Probably a good test of the hardware is use the Linux Live CD that you used earlier. If the graphics are still good when using the Live CD then your monitor and GPU are fine.
If the hardware checks out Ok then I suspect you have a driver problem. Try using a driver cleaner to fully uninstall the ATI driver since bit and pieces left over from previous driver installs can cause problems. The link below is for a free and highly recommended utility for cleaning the system of the graphic drivers. After the clean up I would try installing the original driver that came with your system.

Display problem, and maybe worse

On startup this morning my iMac (PowerPC) G5 display began behaving very strangely. The screen is displaying my usual desktop picture, dock and icons, and finder window. Applications are running, but very oddly.
The screen is covered in small visible dots, some flashing, some static. When I open a document, or a page in Safari, it displays more or less normally (I can use Word, for example), by then "smears" if I start to scroll down the page. At other times the graphics break up completely.
I'm guessing this is a display problem, but one other odd symptom is that sometimes if I click on a file in the Finder window, instead of opening the document the window shuts down and re-opens in its starting configuration.
I tried a restart, but it stuck on a black screen, and I had to force it to stop via holding the start button, and start again from there. I tried accessing system profiler, and it all froze up, requiring another button stop / start.
It looks like a hardware issue, but I've no idea what kind. Anybody recognise what is happening? (I'm posting this from my iBook).

Display Problem - Light Coming From Top

Hello,
So I recently purchased a 27" iMac, and have noticed a display problem when viewing in full screen mode. Its only an issue if there is black along the top of the screen (such as the black bars when watching a movie or trailer). When there is black along the top, you can see some white light kind of bleeding in from the top edge - kind of all the way along (very narrow), but more pronounced at certain spots. I browsed the forums, but couldn't find anything that seemed real similar (though there are a number of reports of a yellow tinge on the bottom).
I guess I"m just wondering if this is a common LED problem - or if my display may be defective, and I should take it back.
Thanks in advance.

Hi Pullo
There has been a few reports, but nothing wide spread.

If it's noticeable, then most definitely take it back.

Display problem T520

I have a T520 4239CTO. Win 7pro. I'm having a display problem. There's a 1 cm grey line 2/3rd down the screen. The image is split--part of the top display is at the bottom. The color on the screen rotates between orange, red, blue, green, etc.
I use the Lenovo update so my drivers, etc are up to date.
How do I figure out what is wrong? I'm currently using a 9-in portable monitor so I can use the laptop on the road.
I've run some of the basic Lenovo diagnostics but it doesn't seem to find anything wrong. Perhaps I'm not using the diagnostic software correctly.
Any ideas? Thanks

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?

Display problem - report /w break formatting

Hi everyone,
I'm having a display problem in a standard report with break formatting on first column and repeat headings on break. Whenever I start a new page and a new group of data starts, the heading for the break is displayed 2 times. If the new page doesn't start with a new group, there's no problem.
I've made an exemple there : http://apex.oracle.com/pls/apex/f?p=25160:9
You can see the group #1 on the first page, no problem there.
On the second page, the group #2 begins and the header is repeated.
On the last page, the header for group #3 is not repeated because it was started on the previous page.
Why is the header for group #2 repeated ? How can I correct this ?
Thanks,
Patrick

Hi all,
I think it is a BUG, that was not fixed in 4.2.
Is it possible to workaround it????
Probably dynamic action with something like this javascript $("#my_table_id").find("tbody tr:(:eq(0))").remove(); With "On-Change" Event on the Region?
But this javascript should be execute only on the pages greather than 1. How can I check in javascript which page of report is actually shown???
Ideas, please!

Display problem import photos

Hello,
I have a display problem when I try to import photos into Lightroom.
I use the version 5.2.
The problem can be viewed in the following video.
At the begining you can view that there is something weird as under the folder "Panoramas" there is a grey block where there should be the rest of the folders onmy disk.
Then, I try to select a folder on my disk MacHD or SaveSSD and everything is ok.
And when I come back on my disk MacSSD, everything is going wrong (it begins when I click on "Panoramas").
Any idea how to fix this ?

My video was just to illustrate the display problem.
As I said before I had it when I import from my SD card. My common workflow is importing from the SD card to the MacSSD disk, with a renaming. That's why I choose copy and not just Add to the catalog.
By the way, I had another strange thing. In the Folders on the left side of the Library module I got 2 times the same name (folder "2013").
I right-clicked and refesh folder, LR asked me to merge the both folder "2013" and it somehow seems to solve the import problem.
I don't really get what I did.......

Display problem - horizontal stripes appear sometimes

I've got display problem. Horizontal stripes appear sometimes (randomly?) on movies or just desktop and stop when I change screen resolution to other and switch back to 1080p. It only happens with my iiyama xb2472hd via hdmi. Everything is fine using Windows. I've tried other monitor via hdmi and the problem doesn't occur.
Any ideas how to find source of problem?
Here is video:
http://youtu.be/dV2d44njQXg
My hardware:
Iiyama XB2472HD + Lenovo y580 which is using Intel HD Graphics 4000 as display device

After months of having this problem I realized that it occurs only with that monitor (Iiyama XB2472HD but probably others too) when I turn it off and than on (after some time) while Arch is still running...
Common situation: I lock the screen in KDE than turn off the display using capacitive button on the device. When I come back after few hours and turn it on the stripes appear. Switching to other screen resolution for a while makes it fix.
Could it be some synchronization problem or something like that?
Have someone any idea how to debug it ?
I believe that someone (kernel developers or Iiyama) made some bad assumptions while implementing HDMI standard...
