30" Display power problems

I have a user that is having an issue with his 30" display every so often goes black and acts like it has no power at all. The weird thing is that it will be dark for some time and some messing around it will come back. Today it took about an hour of messing with it, the last time it took a few days. It is connected to a MacPro so should have a consistent connection and the power supply sets off to the side of the user so it should be protected from feet wondering over it. I guess I have two questions;
Has anyone else experienced this or know what to test?
Does anyone know the part number to get a second power adapter for the cinema display so I can test if that is an issue as I have several 30" monitors but inconvenient to grab one from a user to do testing?

Hi,
You posted weeks ago, did you figure this out? The part number should be 611-0390 and/or 661-3356. A few online retailers have it, I got one from applepalace.com
It didn't solve my issue though, so look out for restocking fees if you buy one....
The guy there told me by phone that the board inside the monitor is probably kaput.

    Suggest Solution for this Display Flickering problem ....

    Hi, I read the post about calibration and I probably do that a little too often TBH! As I get so little time out the battery and mainly use my MBP on my lap, usually with the power supply near by, it gets charged to full, run to empty to the point of sleep, or sometimes it even cuts out and then is recharged to full again, so I really think it's new battery time. I've seen non Apple Official ones for between £35 and £65 that have 3 year warranties and state they are around 5200mh but am unsure due to reviews.
    Later...
    Anyway's I have now ordered a non Apple replacement from Amazon for about £35 and it has several good reviews and 4.5 out of 5 stars so I'll see if it works and report back. If it doesn't I'll send it back and get the Official Apple one.

  • Intermittent power problem Canon 5D Mark iii

    My Canon 5D Mark iii (2 years old) has an intermittent power problem, as described below. It may simply be a question of cleaning the terminals that the battery connects to. I haven’t tried since I can’t reach them at the bottom of the battery compartment.
    Details as follows:
    this is a recent problem in the last 3 weeks
    the problem occurs with all three Canon batteries that I use
    from time to time when the power is on, the camera suddenly loses all power and displays an “empty” battery image
    sometimes it happens of its own accord while no demand is being placed on the camera
    but more usually it occurs at the moment of focusing (I use back focus on the * button)
    it is often fixed by turning the power off and then on again. This fixes it half the time
    it is always fixed by turning the power off, removing and then re-inserting the battery
    needless to say this is very annoying!
    Since coming back from a trip, while transferring images from the camera to my computer, I noticed that the (almost) full battery started showing “empty”.
    The transfer was completed successfully, and when the camera was disconnected from the computer, the battery showed that it had lots of charge left. Very puzzling!

    It sounds like either the battery terminals aren't getting a solid contact or there's a fault (something loose or grounding out) inside the camera.  But if something were genuinely loose or grounding out inside the camera, then power cycling or even re-inserting batteries would probably not fix it -- which makes me suspect it's still something outside the camera.
    Are any of the batteries new, or are they all about the same age as the camera?
    Batteries only last a few years but it'll depend on how they were used.  In other words if all three were used about the same and enough charge cycles to be at the end of their reliable life... it might be time to replace them.  
    It's difficult for the internal battery terminals to get dirty unless the battery itself had something on the battery iteself when you inserted it.  You can try a bit of denatured alcohol on a cotton swap to reach in and clean the terminals.  Also, inspect the batteries to make sure they're all clean.

  • How can I fully used the display power in VMWare Fusion

    Hi,
    I am a newbie in in MAC. I've bought a MBP with embedded & standalone display card. I have installed windows in VMWare. However, it's display power in Windows Experience index is just 1. I think it's due to the display driver used in something call "WM SVG2", (not sure, as I am not next to it now). Also, I found there is an unknown device which I think is related to the build in Webcam
    Can someone help me:
    Can I fully utilized the display power of my MAC and how?
    How to resolve the unknown device related to the Webcam?

    No, sorry. There's no way to do that in a virtual machine. Remember, that OS X is the booted operating system and it has control over your hardware. The virtual machine, as far as OS X is concerned, is just another application running alongside any and all other applications (and really, that IS all it is, just very clever software to emulate a computer within a computer). Any hardware calls from Windows have to go through the virtual machine software interface and then are handled by OS X. OS X does not support using both video subsystems simulataneously, and even if it did (or perhaps will, in future machines) your installation of Windows cannot access ANY hardware directly, so you still would be unable to achieve true native Windows performance.

  • My MacBook Pro with Retina display displays power point and not other windows when connected to a projector

    My MacBook Pro with Retina display displays power point and not other windows when connected to a projector. Can anyone help out please?

    You should also ask this in the MacBook Pro forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

  • MacBook Pro Power Problems.

    My MacBook Pro is exhibiting power problems. I am running Yosemite and it seems that the problem may have arisen since I dowloaded this upgrade. When the battery is charged it shows 99% charge and I can use it on battery power. As normal with use the charge gradually reduces, say to 30%. I then switch off using either the on/off button/apple logo, waiting for the dialogue box, " do you want to switch off etc". The next day, I switch on, but the computer will only boot up when the power lead is attached. When the computer comes on, usually as normal, the charge always shows 0%. When it is recharged the whole process repeats itself. Help please.

    Hi,
    Thanks for responding. My MBP is late 2009 and the battery has never been replaced. When I look at battery condition, it registers as normal, as it does when I do the power checks you suggested. When I plug in the power cord it glows green and within a few seconds it is on amber, until fully charged. I've done the SMC reset. I  noticed this morning that after using it last night the battery capacity was 93% and an expected duration of about 5.5 hours was listed. After limited use this morning, restricted to email admin only, the charge level had dropped to 88%, but the predicted duration was only 2.75 hours. Currently the level is 73% and the duration is  3 hours, although I have accessed the web several times. Presumably there is some sort of algorithm that looks at current usage and predicts the duration. I will continue to monitor this to see what happens. In the meantime if you have any more thoughts!!!
    Regards

    Welcome to Apple Discussions!
    Pictures would help. A good way to do this is to post them to a free photo sharing site like Flickr and then post a link.
    Also, you are in the original MBP section, and I think you need to post your question in the newer MBP section:

  • Hard Disk or Power Problem

    I have a Powerbook that I have had for many years now. Recently it hasn't been booting up. I hit the start button and it chimes like it usually does but the screen and hard disk don't do anything. Sometimes it does boot up but it doesn't start easily. When it does boot sometime freezes when I go through the login and when loading the desktop but once the desktop is loaded it works fine until it goes to sleep. I just bought a new battery for it this summer. I have been reading though the Discussions and I figure my computer is either having power problems when starting up or I need a new hard disk. Any thoughts?

    You will find step by step directions at iFixit. Note that your computer does not have the EMI finger referred to in the directions. Also, be especially careful with the tiny screws in the sides on the computer. You don't want to strip the heads or it will be very difficult to get them out. Here are few tips you may find helpful:
    • Print out the ifixit directions as well as the screw guide ahead of time.
    • Be sure you have the right tools. You don't want to damage the screw heads or you may never get them out. And the Torx screw driver is critical. For a spudge I use the handle of an old toothbrush (choose one made of hard plastic), cut off the brush and beveled the handle end like a flat blade screw driver). For some spudge jobs a credit card will do the trick.
    • Click on the pages of each step which involved removing screws to enlarge, then print out the pages. Poke holes in the paper where the screws were removed, poke the screws in the holes and stack the pages in order in which there were removed. Reassembling is a lot easier. No cups to tip over and spill. No guessing. Each screw is exactly in the right place. You can use an ice cube tray, egg carton, dixie cups etc. I previously used small medicine cups one for the screws in each step. I nested them so that the last ones out and the first to go back in are on top. (Some users report cutting up the screw guide and placing the applicable section in each container.)
    • Be very careful pulling out leads. Hold the lead as close to the plug as possible and wiggle (the plug ) to loosen its grip. Don’t hold the wires and pull as that can damage the cable, or worse, in some instances pull the wires out of the plug. Indeed, some users have pulled the socket off the logic board! Use needle nose pliers or tweezers if you can access the plug, or nudge the plug with a small instrument to help loosen its grip.
    • Use force gently in removing parts. Separating upper and lower case takes some doing. Use a plastic tool (spudge) so as not to leave marks.
    • Refer to the screw guide when reassembling computer. Putting longer screws in the wrong place can perforate the circuit board.
    So will I be able to put the OS and everything on by the installation discs?
    Yes you will. Indeed you may be able to clone the contents of your current HDD to the new HDD by placing the drive in a firewire enclosure and formatting and cloning the new drive before installing it in the computer. If you have data you need to backup and have a sound installation on your current HDD this might be an option to consider.
    When you get your new HDD it will need to be formatted before you can install the OS on it. If you need directions for formatting and installation, I can post step by step directions here for you. Let me know.
    Good luck.

    Howdy rcoo26,
    It sounds like there’s an issue turning your MacBook Pro on when it isn’t connected to power, and the battery doesn’t seem to be holding a charge. The article below provides information that can help you troubleshoot the battery in your notebook.

  • X200's display has problem

    Hi all,
    I just bought an X200 7454-2JU a couple days ago.  I'm wondering that the display has problem which is similar to a wheel on the right hand. I also attact my picture at: http://www.pitini.com/status/x200.jpg
    I'm going to call the retailer for an exchange, but I need your advice first.
    Thank you.
    Kim

    Thanks for your post. I'll call the retailer (Newegg) tomorrow. That's so bad.
    It was DOA (Dead On Arrival). It is obviously to see it from BIOS to windows backround. I do not think that Lenovo, a famous brand name, could not detect this error before package it.

  • I'm going nuts with display driver problems!!!!

    Hi everyone,
    I joined the forum some time ago but I can't get back in so I logged in with a new ID.(Pain)
    I have a problem that I hope someone can help with When I place any of my work or a photo into CS5-Ext. I can't do any work on it? No matter what tool other than the paint brush I use, as soon as I click on the picture / work it disappears and will only re-appear if I click on it again. I've tried all sorts and it's driving me nuts, Can anyone help?---PLEASE---
    Thanks.

    That sounds like a display driver problem.
    What OS are you running?
    If Windows, you can often visit the web site of the maker of your video card and download/install an updated driver.
    If OSX, you need to look to Apple and their OS updates to get updated display drivers.

  • Mini Power Problem

    My mini (2009, Intel core2 duo, Snow Leopard, up to date) has a power problem. Perhaps it has overheated.
    It shut down unexpectedly, without warning.
    I try to start it by pressing the power button. The power light turns on briefly. there is no chime. Then the light goes out.
    I tried resetting the SMC. No effect. I tried holding the power button in. The light stayed on for several seconds, then flashed rapidly 10 times, and turned off.
    I have given it over half an hour to cool, and placed a fan behind it to help.
    No change.
    Thoughts?
    Other minor points. I upgraded the RAM and hard disk 6 months ago. No problem.
    It is running dual monitors, Wireless is turned off, ethernet is on, and I have a speaker plugged through the firewire port. But I tried disconnecting everything and restarting naked. No help.
    I'll try again now... nope. Please advise.

    Next bit of data. The chime does not happen. That seems to have been a single occurrence. I've opened the mini, and see the internal green LED on the motherboard is lit. When I hit the power button, then may be a tiny whirr. I'm not sure whether it is the disk or a fan. But it lasts a fraction of a second, then the main external power light goes out, and the motherboard green light also goes off, then comes back on. I'm thinking there may be a big power draw (disk drive? Fan?) exceeding the power available, and it shuts off. Possible?
