20" display not working properly

The display only works with a 90w brick instead of the 65w brick it came with. It was intermittent for a while and then it just gave me the light code of short, long, short, which says: "Make sure you are using the correct power adapter with the display. This alert will only appear on displays built in 2004 or later which require an external power adapter." When I switch out the brick and use it on another 20" display, they (both the other display and the brick) work fine. When I try the power supply from my 23" (the 90w brick) the 20" monitor works. Everything is plugged into a UPS/surge protector.
Bottom line: I don't think the brick is bad. I think the display may be about to go?
Any ideas?

20" iMac, display not working properly, otherwise OK

I have a 20" imac with 10.4.11 loaded, Have had it for about 2 years, no problems at all except occasional wake-from-sleep issue. All of a sudden, the display has quit working properly. The computer sounds like it boots fine, but the display only shows a very deep blue (not black)and the light ind the lower right corner is "on".
I tried holding a flashlight up to the front as some have suggested, and I do not see see anything at all. This would seem to rule out backlighting or screen brightness issues. I have also reset the PSU and the P-ram, also to no effect. Tried booting from the 10.4 disk, also to no effect.
My teenagers won't admit having any problems, but one of them did admit to turning off the system several times using the power button in an attempt to reset AirPort. Any thoughts? the only other easy thing I can think of is the battery, could that be causing this much trouble? do the display cables ever detatch from the MB or anything like that? any ideas greatly appreciated.
Thanks, Eric

Hey Eric,
This is from the Service Source:
"Screen is dark, fan is running and the hard drive is spinning. You may hear the startup
chime as well.
1. Reset parameter RAM. Press Command-Option-P-R during startup before “Welcome to Macintosh”
appears.
2. The system software could be damaged. Start up from the system CD that came with the computer.
3. Remove the user access panel on the bottom of the computer. With the unit powered on, check if a red
LED is visible in the access door. If the red LED is on, power is on. If you don’t see the LED glowing
red, follow the steps under the symptom “No Power”.
4. Disconnect the A/C power cord. Place the unit in the service stand and remove the user access plate.
Press the PMU reset button on the logic board. Refer to “Resetting the PMU on the Logic Board”
mentioned earlier in this chapter.
5. Check for external video. Connect an external monitor to the mini-VGA port. If you don’t have external
video, replace the main logic board. If you do have external video, go on to the next step.
6. Open the bottom housing and verify that all the cables are securely attached. Pay special attention to
the video cable (located near the modem). If the cables are securely attached, go on to the next step.
Warning: Whenever the bottom housing is opened for service, you must do two things:
• You must clean the original thermal film from the surfaces joining the thermal interface layer and
reapply thermal paste to the thermal pipe.
• The bottom housing has four torx screws that must be tightened to at least 17 in.-lbs. If you do not
have a torque driver, you will have to make sure these screws are tightened by hand FIRMLY, BUT
NOT FORCIBLY. Or, purchase the service tool (076-0899) in order to ensure the thermal pipe is
firmly mated with the top base. If the bottom housing is not securely attached to the base in this
fashion, the CPU may overheat and become damaged.
7. Check the connection of the video cable to the LCD flat panel display (under black tape).
8. Replace the inverter board.
9. Replace the LCD display. Important: If you are replacing the display, be sure to install the new display
shield and EMI gaskets that come with the new LCD panel. Installation instructions are included with
the new display panel. Additional display shields/gasket kits are also available separately as a kit, part
#076-0958.
10. Replace the neck assembly
11. Replace the logic board.
12. Replace the power supply board."
In my experience the connectors both on the logic board and on the back of the LCD panel have been known to come loose. I also have a neck assembly here that went bad.
If you need more info email me.

Display not working properly

Hi,
When I connect my Samsung SyncMaster 19" with the DVI-VGA adaptor to my MacPro it won't recognize the default 1440-900 / 60 Hz resolution.
(Preferences says VGA-monitor, and 1440-900 is not listed)
When I start the MacPro without the SyncMaster connected, and connect it after the MacPro has started, it automatically displays 1440-900 / 60 Hz and the Preference displays SyncMaster!!??
Conected to my PowerBook (also DVI-VGA), the SyncMaster is recognized correctly, and I can choose whatever resolution I want..... (Labeled SyncMaster in the Preference as it should)
Hope someone can help me with this....
Greetings,
Michiel

Try resetting your phone. Press and hold the Volume Down and the Power button at the same time for 10-15 seconds, until your Maxx powers off, then power it back on with the Power switch, as normal.
To see all five pages, you can also press the Home key while you're on the main home screen. That's how it works on my Android device, anyway.

Display not working Properly please help???

Hey all I have read thru about 25 pages of different posts relating to the video screen problem, and none see to be exactly like mine. I have 1st genereation IMAC G5, that had the orginally logic board problem where screen wouldnt come on at all, i got it fixed once under apple care warranty, then i had another problem where system kept crashing causing automatic restart which apple store genuis bar said was also logic board, this time i was out of applecare coverage but, i got ot covered thru the extension program that just ended in dec '08. Last week when i got home my screen was off, i restarted by holding pwer button down, then i got partial screen( only dock bar items, prgrams, & etc where showing, no desktop files), so i restarted again and got this strange pixeliate screen after loading(see image: http://i152.photobucket.com/albums/s183/nofate21/Picture001.jpg), so i rrestarted know during loading process I get normal apple logo, but with horizontal pink lines running thru screen at variables( see image:http://s152.photobucket.com/albums/s183/nofate21/?action=view&current=Picture003 .jpg & also http://s152.photobucket.com/albums/s183/nofate21/?action=view&current=Picture003 .jpg). Now it varies when i restart CPU, sometimes I get completely black screens, sometimes i get blue screen with nothing, and the last couple of times I get a black scrren with a mouse cursor that moves normally. i have also tried restarting while hook-up to external display(my lcd TV) and I get same image (although minus the intermittent/variable horizontal pink lines), please help with any suggestion or even advice( such as trash it, try to fix with ordered parts, etc) Have appt with genuis bar, but already know the will say $800-1000 for new logic board or whatever

Are you saying you already got it fixed but the problem is reaccuring??
I am part of the unlucky ones who didnt't have applecare or the extended warranty. My iMac broke down 8 months ago. I no longer have any display. The strange thing was I left it at home because I went to uni, so there was a period of at least 10 months where it was not used. But still it failed within a few weeks of me getting back home. I was sucked in by their adverts making me believe they were a superior computer to any windows based. How wrong was I. It has now left me with a very bitter taste.
Any of you guys know if it still will work if I connect an external monitor?

HTML field display not working properly on net

I'm using an XML file to dynamically load info into a
textfield which is .html = true and htmlText is placed into the
field. One such entry looks like the following:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<glossary>
<entry>
<term>Rural</term>
<definition><![CDATA[According to the Arizona
Department of Health Services, 'frontier' areas are defined as
having less than seven (7) residents per square mile of land.
'Rural' areas have less than 15 residents per square mile of land
(ADHS, April 2005).<li>Arizona has 4 frontier counties and 4
rural counties. A total of 10.7%
</li>]]></definition>
</entry>
</glossary>
This works fine when playing back locally on preview in
Flash. On the net, it actually shows the html markup, despite
having the field set as html and using htmlText to populate the
filed. Flashplayer 9 all around. Any ideas?

Lock screen display not working properly on wakeup from screen sleep

I just purchased a macbook air top model mid 2012... yesterday. It's brand new. When I click the trackpad to wake up the screen after it sleeps and has auto-locked (not a computer sleep! just a screen sleep), the screen is not all present. I have to move my mouse around to reveal the rest of the screen. Once I have done that enough to find my icon to enable text entry, I put in my password and I get back to the desktop which is then normal. This behaviour is only occuring on a wake-up after screen sleep. Seems like a video driver problem to me. The only add-ons I have at the moment are alfred and bettersnaptool. Has anyone run into this? Is there a fix? Also, I have applied all the latest updates. I can't remember, but this might have begun after the latest update.
Thanks,
John

Air Display not working properly after closed and re-opened

I have a late 2013 iMac (21 inch - 8gb of Ram) and am running 10.10.2
After starting the iMac up and choosing Air Display it 'mirrors' webpage videos well through Apple TV.
The problems start when the Air Display 'mirroring' is turned off and then turned on again.
After Air Display 'mirroring' is turned back on the webpage videos stutter and seem to pulse or falter and the only way I can sort the issue out is to re-start the machine and put mirroring on again.
Has anyone encountered this and does anyone have any suggestions about how to sort this problem out ?

I Don't know what type of issue this is.
I Don't use the Airdisplay all that much so singing off the wifi does the trick well enough for me.
MAybe the the latest software update fixed the issue, as I said I don't use this function a lot.

Image display control scrolling does not work properly when zoomed in

I am using a ROI on an image in the image display control. When zooming into the image to fine-adjust the positioning of the ROI, the image scrolling does not work properly. As far as I understand, the image should scroll automatically when the ROI is leaving the visible area. However, the scrolling behaviour seems to depend on the origin of the Labview panel, not the origin of the image display control, which might require to move the ROI way out of the visible area before the scrolling takes place. In other words: the coordinate system of the image display control is shifted with respect to the true visible image area, depending on where you place it on the front panel. As a consequence, when clicking on a ROI which is in the visible area, but is outside of what Labview thinks is the visible area, it might immediately jump to the left border of the image, making the positioning of the ROI really difficult.
Has anyone noticed this behaviour, and what would be a reliable solution to avoid this?
Dirk

Hello,
no, I am not talking about the tools palette. Just place an image control with some image in it on a new VI front panel. Then, use the rectangle from the tools and select a ROI in the image. If you zoom in (using the magnification glass), and then grab the ROI and move it around, the image scroll with the ROI. So far, so good. If you now place the image control elsewhere on the panel, or add new control above it, resize the panel, etc. , this scrolling when moving the ROI will not work correctly if the origin (0,0) of the panel is far away from the image control.
I have attached a VI for simplicity (although there is hardly any code in it).
If you make a ROI and try to move it down, you will notice that scrolling starts if you move the mouse out to about 10cms below the image (depens on your screen, of course). After that, if you click on the ROI, the scroll bars and ROI might jump up to the upper end of the image. Imagine how annoying this is if you try to finely adjust the ROI position.
I think it is a bug in the implementation of the image display control.
Thanks,
Dirk

Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

XFCE4 not working properly display X as cursor not arrow pointer

Hi all
I have recently installed arch and XFCE4 as my desktop environtment everything went well for a few days.
But all sudenl 2 days ago thing appeared not working properly. Things displayed on my desktop are out of proporion mainly the X as cursor instead of an arrow, newly opened windows default to top right cornner overlap my taskbar panel not able to move this. I've tried to re-install xfce4 but weren't sure I did it correctly.
tried :
pacman -Rdd xfce4 xfce4-goodies
rm -R ~/.config/xfce4
then reinstall problem still occurs.
Any suggests and help would be greatly appreciated.
thx

Be sure you cursor theme is complete. Which one are you trying to use? Did you try setting it up from directly X confs?
There must be an option in window manager or window manager tweaks about overlapping taskbar. You can use alt+left mouse to move your windows till it is configured.
Reinstalling is as meaningless as deleting system32. If you are out of options, just delete your .config folder then reinstall.?

Display has white and grey lines and blocks crisscrossing it and touch functions are not working properly on half the screen.

I dropped my iPhone 5S and it landed flat on it's face (it was in a protective case). Since then my touch screen display is not working properly. I have white and grey lines and/or blocks crisscrossing the screen both horizontally and vertically. Screen responds to touch in odd random ways, but rarely does what I am trying to do. Can't call or receive calls because can't dial or answer phone via swipe. Can't text or read incoming texts. All functions seem to be working except that I can't access them because the touch screen is acting up. If I move the phone around it randomly accesses different apps or functions, but I have no control over them once the appear on the screen. Touching screen just causes phone to randomly choose something else to open. What have I damaged?

We cannot possibly tell. Obviously some hardware inside. Take it in to an Apple Store. They will offer you the opportunity to swap the phone for $269 in the US. Prices vary by country.

Flash player does not work properly on Windows 7 32 bits

Hello,
My flash player does not work properly on Windows 7 32 bits with Firfox and IE8 (lasts versions).
My Flash player version : 10.0.45.2, but I tried with version 9 too, with same problems.
I have tried to uninstall, reboot, reinstall several times, ... witch did not worked.
In fact, it works correctly on some sites, like youtube, but not on some others like :

But in the Global Privacy Settings panel (http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager02.htm l), I cannot change any settings :
I cannot check boxes,
My changes are not saved.
In most of flash animations, videos, ...,
when I click on parameters, I cannot do anything, even closing.
when I am in full screen mode, the message "press escape to exit...." does not disappear.
Last thing, all those problems was not there when I was on Windows XP, few weeks ago, and appear with my registered Windows 7 premium familly edition, with the same hardware configuration...
Thank you for your help
