Black screen, can vaguely see image

About 2 years ago applecare replaced my lcd screen (actually the neck and everything)
I can't BELIEVE the inverter is gone....
is there some other thing it could be?
I booted from an external hard drive last night, ran disc utility ,
rebooted back to main drive. The computer was fine.
I woke up this morning....black screen!
boooohoooooo:(
thanks
laura

Hey Laura,
I booted from an external hard drive last night, ran disc utility ,
rebooted back to main drive. The computer was fine.
I woke up this morning....black screen!
So this morning was that booting from the internal drive?
If not that could be like #2 below.
This is from the Service Manual:
"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."
So my money is on the PMU, inverter cable, inverter board or that connection on the back of the display.

I bought my iPhone5 on Wed, now on Sunday it no longer works (black screen, can't see any indication it is recharging). I had a iPhone 4 for over a year, so I know how to turn it on and it worked yesterday. Could it have been deactivated?

The question is in the title...what do I do now?

Try resetting it: push both the power/lock button and the home button at the same time until the Apple logo appears

Thank you ;- )

Have you tried restarting or resetting your iPhone?
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after It shuts down, press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds).
No data will be lost.

I can not see images on a HDMI TV connected my laptop Displayport

Dear all,
I need to connect the laptop to a HDMI TV and therefore I purchased a HP Display port to HDMI cable adapter P/N: 612873. It is not working.
I phoned HP service, they recommend to me to download the HP Softpaq download manager and update my laptop.
After doing this, still I can not see images on the TV.
I know the TV is working, because other laptops like Asus, Toshiba are connected to the TV and works fine.
Does anybody know what should I do?
Thanks in advance.

Screen turns grey but can still see image

Hi all,
I don't really know how to explain this but recently I am getting this grey shading on my screen. I can still see the content if I tried to but it's really hard. At first I just wiggle my screen a bit or give it a tap around the screen then it will return back to normal. But the problem is getting worse and worse. Wiggling and tapping the screen doesn't really do the job anymore. I just got this new screen about a month ago under Apple's warranty. I'm thinking maybe when the technician installed the new screen, he didn't attach something secured enough and it has come lose.
Anyone having similar problem or know what's going on? My warranty just expired 4 days ago.... Hope it's nothing major or I'm spending my own money :/
Oh and I've been reading about snow leopard having screen issue.... not sure if this is related but I did upgrade to snow leopard.
Message was edited by: MacBookProOwner

this sounds like the same problem i am having. for me, the bottom 1/3 to 1/2 of the screen will fade, like every other pixel is going white. then it will start turning grey. by the end its all dark shades of grey, but streaked vertically to match what's displaying on the upper part of the screen. the whole thing happens in a few seconds. the rest of my screen is fine. does this sound like your problem?
if it helps, i bought the mac in 2007, and had to have the video card (i think) replaced because it had the problem of the screen staying black when opened from sleeping. if anyone has any advice, please let me (us) know. thanks

Using Firefox to access facebook chat Button or online friiend chat button generates a Black screen with CANNOT LOAD IMAGES and no chat window opens.

This does not happen in other browsers and it happens on a variety of computers I have access to and would seem to be a common problem but I can find no identical cases in my searches of
Firefox , Facebook or windows help or Google search. My home machine is only a P2 with WINXPCORP but works fine and I have done all updates but still have this continuing problem every time I try to use Firefox
to access Facebook chat but it does not happen with IE or chrome
The response to clicking on chat button or friend chat is a black screen with small center square box with blue title bar that says
'' VIEW IMAGE FULL SCREEN - (42) FACEBOOK X""
center of box is ""! "" mark in yellow triangle and wording
"" CANNOT LOAD IMAGES ''' OK
clicking on OK returns to facebook page but no chat opens.
Some times |VERY RARLEY if as the page loades you click on
chat button with 1/2 second of it appearing chat will open.

Hi,
Please also see [https://support.mozilla.org/en-US/kb/Problems%20using%20Facebook%20in%20Firefox this.]

Import Clip to motion, can not see image

I am using motion 4 the first time.
Tried from FCP <sent to Motion, and also open Motion and use import command.
All I can see in the canvas is a black screen with a few colored lines.
Tried several view options.... all the same.
Can not find the way to change my view.

I did some searching and found a post, which suggests to remove the com.apple.motion.plist. Strange thing: I can not find it, even using spotlight, does not show that file (suppose to sit in Library>Preference folder.)
An other post suggested to remove Motion and reinstall it.
I had to do it twice because the first time it kept on crashing. Then I realized, I need to upgrade running as well.
When I open Motion now and import a movie clip, I can see an image, but it looks like the shadow slider is pushed far to the end (images are high contrast-black with some funky colors.)

Black screen - can not get in touch with my Ipod Nano

I have an Ipod Nano, latest model. After a short time the monitor shuts down and turns black / standby, can ths be disable?
I use my Nano with the Nike Ipod censor when I run, and it is diffical to get in touch with my Ipod Nano, when the screen after a short time have been black.
Should I see my runningdata or to stop the censor when I'm finishs running, and press the screen nothing happens.
Press I on / off button, so either I get a voice that tells a lot about my run, or push me 2 times on / off button toggles track.
If I press the + or -, I change the volume.
Keeps press on / off button, turn off my Ipod Nano and all my recording of my run is lost ...

Possible causes:
1. Your antivirus is blocking access to gs.apple.com.
2. Your phone is jailbroken.
3. Your computer has been used at some time in the past to jaibreak some iOS device (not necessarily the phone with the problem), and its network database was corrupted by the hacking software that was used.
4. Apple's activation servers are down (very rare, and never for more than an hour or so).
For 1. try disabling your antivirus.
For 2. & 3. you need to go somewhere other than an apple forum for help. Although you can try deleting lines containing gs.apple.com from your "hosts" file on your computer.

I have I pad 2 I have had it since Oct 2010 it will not turn off I have a little star thing spinning in the centre of a black screen can anyone help me as how I can take off hanging and turn it off

I have I pad 1 and it is hanging I have a black screen with a little star spinning in the centre of it I can't turn it off or on.
Can anyone help

That's what the iPad does when you turn it off, and for future reference, you never really have to turn off your iPad. iPads have great sleep modes, and lose very little battery life during sleep.
Also, you do not own an iPad 2 as stated in the title, they came out in March 2011, while you say you've had your iPad since October 2010.
I doubt this would work, but try resetting your iPad by holding down both the Home and Lock buttons until the device restarts.
You might just have to let the battery die on you if that doesn't solve it, or take it to your local Apple Retail Store for a Genius to look at it (be sure to schedule an appointment by searching your store in the search bar at the top of this website, and going from there,) you may also want to check out the 'More Like This' section to the right of your post to see if anyone has a solution for this.

Blue hp circle on black screen, can\'t access boot options for recovery disk

I installed Symantec full disk encryption and encrypted the hard drive. Then I restarted the pc. I get a black screen with a blue HP logo in the center. Message at the bottom right sysa press the ESC key for startup menu, but no key works. Every key pressed gets a beeping sound. If I turn power off and then on and press the different f keys, I get different messages but still no response from any keys.
Symantec sent me a recover disk to deencrypt the drive but I can't get the pc to load from the drive. Any thoughts?. I have hard reset the pc twice ( battery and power cord out, hold power button for 30 seconds)
This question was solved.
View Solution.

I would remove the hard disk and then power up the notebook to see what response the BIOS has.
From your description of the problem, it sounds as if you may have encrypted the entire disk instead of just the C: volume or the BIOS ROM file is corrupt.
You should be able to get past the HP screen to enter the BIOS.
The BIOS should give complain that it cannot find a drive with a bootable OS.
If that does happen, and you have the recovery disk set or usb recovery media, life is good and you will need to take a look at the Symantek forum to see how to proceed with your encrypted disk.
If it does not then, the problem lies with the BIOS on the system board.
Pressing the Esc key and having the startup menu appear is conditional on the BIOS being in good condition. Yours may be corrupt. Try downloading a BIOS softpaq on another PC, extracting the BIOS ROM file and putting it on the root of a usb thumbdrive. Put the thumbdrive in a USB port in the notebook. Press the power button and immediately hold down the Windows key and begin tapping the B key. If this works and you see an led flash, release the keys and wait. the process should load a clean BIOS file to replace the corrupted one. This takes time, so be patient if you see a flashing led or no reaction from the notebook for a couple of minutes.
Post your results here and we can move on to the next steps you can take.
Best regards,
erico

I have an Imac and I use mostly "Firefox" and I am "not too" computer savvy and it seems that now I can not see images on Firefox at all. Therfore i can not see what I am clicking on (like "to buy" or "next" .. PLEASE help me! Thanks in advance!

I am "not too computer savvy" so if you are going to answer my question.. Please take super baby steps (thx in advance).. Okay, now I have a 1 yr old Imac I am using 10.6.8 (do not know what that means) but everytime I call Apple support they ask me.. So I figured you may need to know as well. I really love Firefox (easier for me) and I was trying to download a coupon printing thing to print from Coupons.com (plz don't laugh..economy sux) anyways, the operator at coupons.com told me how to install it. Can't remember but if not immediately after or not long after?? It seems that ALL my images on EVERY website are gone. It is very frustrating because I can not see (for example on Ebay where to click "buy it now" or "continue" unless it seems I sometime get lucky and click where it says "image" but there isn't one. It looks like a set of shark teeth actually right beside the word "image" very jaggedy teeth, I guess?? So I have been using Safari. There is no problem with ANY of those website images. I go on the same basic sites so that is how I know that. I have only downloaded music I think 3x. I do not download much at all. I would really love to use Firefox, being the un-savvy computer person I am... Firefox is easier to navigate for me. Thanks SO much!

Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.
*Firefox > Preferences > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"

Black Screen - Can't Boot to SAFE Mode or Advanced Options

have a three month old Inspiron 3847 with Win 8.1 that cant boot past the black screen. It does not go to Advanced Options like it should and the F8 key does not take it to SAFE mode. I do not have a bootable media to install. How can I repair this PC?

Go to run, type msconfig, hit enter, click on boot when the window opens then check safe and reboot.

I can't see images or icons in firefox or emails downloaded with firefox. What do I do to fix this? Thank you.

In particular, I can't see the up and down arrows that enable me to move from one email to another in gmail. There are many other problems: I can see NO icons and I can see NO images in my emails, whether it be hotmail, gmail, etc. when I use firefox. I read loaded firefox and got the same result. How can I fix this. Thanks.

The Yahoo! Toolbar and the Babylon extension have been reported to cause that problem. They seem to invisibly extend downward over the top of the web page display area. Disable or uninstall those add-ons.

In which screen can I see profit centre MARD - PRCTL

Hi experts,
In the material master screen where can I see the MARD-PRCTL field. I am not able to find it.
Any suggestion would help. Assure of points.
Francis
Edited by: Francis Yesudas on Jun 11, 2008 2:08 PM

I got this update from early forum post:
The MARC table holds the Plant Data for Material in the material master.
The MARD table holds the Storage Location Data for Material.
The MARD table is populated when the stock level of the material is updated.
So, the subsequent fields of the table including PRCTL (Profit center) gets populated when the corresponding transactions for updating the material stocks are executed.
How do I update the stock level of the material? Goods movement?
