Screen going black on T42

My T42 has started going black as if in standby but it is not. I replaced the AC adaptor because it did not do it while on battery but now it is doing it on battery too. Any suggestions as to what the problem is. I am running Windows XP Pro.

Can you please run PC-doctor on all components of your system, especially video adapter, and also post the full 7-character model number (237?-???) of your T42?
Good luck and let us know.

  • Screen goes black when hooking up to TV via mini-DVI to video adapter...

    Hello,
    Ever since I upgraded my PB12" to 10.5.x (now running 10.5.5, but this issue has been there since upgrading to 10.5.1), when I hook up the mini-DVI to video adapter (different adapter than for hooking up to an external display as the mini-DVI to video adapter has composite and sVideo out) to my TV, the PB screen goes black. It's set up to mirror the PB on the TV, and the PB continues to run, picture works on the TV, but I loose picture on the PB. Only way to get it back is to reboot the PB (with the mini-DVI to video adapter unplugged). So, basically, if I try and use the mini-DVI to video adapter, I loose picture on the PB. This never happened under 10.4.x — only since upgrading to 10.5.x.
    Anyone have this issue? Know of a fix?
    Thanks,
    Kristin.

    If you connect the MacBook using a Mini DisplayPort to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo sound system if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. The Mini DisplayPort to HDMI doesn't carry audio unless you have the Mid 2010 model 7,1 and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.
    If you have the Late 2008 model 5,1 Aluminum Unibody or Late 2009 model 6,1 White Unibody with the Mini DisplayPort rather than the Mini-DVI there is an adapter that can combine video and audio to HDMI.

  • Mid 2010 MacBook Pro crash - screen goes black

    There is a major problem with the mid 2010 Mac Book Pro's and Lion.  I suspect that it is related to the drivers for the NVIDIA GeForce GT 330M 512MB video card and perhaps the i7 processor.  The crashes are random and most often occur after a mouse click then the screen suddenly goes black and a restart is forced.  There is a thread on MacRumors that describes many others with the same problem: http://forums.macrumors.com/showthread.php?t=1182104
    The crash occurs less frequently when the power and external monitors are connected.  When the MBP is unteathered it crashes every 20 minutes.  I am really surprised and disappointed that a bug this severe made it through final testing. Looking forward to 10.7.1.

    im so glad im not the only one with this problem. at least i know its not because some careless things i unconciously did that makes my mac gone berzerg like this.
    i also encounter the exact same problem with all of you. problems started a month ago. at first it was just once in a while then it became a frequent thing especially when my battery left with 20-30%. then after i plugged in the magsafe, its okay. lately, nothing safes the mac from crashing, particularly when im running adobe and/or autocad. i thought it was software problems so i backed up my files, performed erase and install snow leopard then made an even bigger mistake by upgrading to lion. after finish upgrading, the crashings got even more often. every starting up, after i got a glimpse of login in, pufffttt, screen goes black but keyboard still on. googled it up and say reseting smc will do the trick. eeekkkk nothing! then resetting the pram. worked okay for quite some times then puufffttt, crash! ask a question on yahoo answers and got a help from lovely person to install gfsxcard-something and told to opt for integrated only. worked fine for 2 days and still went back to crashing. opened up the mac, testing each rams, reshuffling em, still got nothing. the only thing that enables me to do my work with this Majestic mac is resetting pram everytime i turn it on.
    since im living in singapore (bought this mac june'09 in melbourne,australia), there is no genius bar to be found, running a diagnostic only at any apple service cost me 120 bucks and if i have to change the logicboard, its gonna cost me ard 1000++ dollas since i dont have any applecare and my warranty expired 4mnths ago. so, i might be killing myself soon! yauuzaaaa

  • MacBook 13.3" (A1181), 2.16 GHz, screen goes black once OS is loaded.

    I have a MacBook 13 (model A1181, 2.16 GHz) that I bought from a friend.  Everything starts up fine, I get the chime, etc., until it loads the OS.  I have a brand new Apple hard drive; brand new Mac OS X Leopard disk; and have tried everything I can think of.  I have tried shining a light to see if the screen is just dim--no dice.  I have tried completely wiping the drive clean on my iMac and then reinstalling.  It gets all the way through the install, then the screen goes black when I'm trying to set my information up.  The screen stays up if it's installing the OS, and also if I have the hard drive disconnected on the logic board.  As soon as I load the OS, it goes black.  The rest of the machine is still running.  I have a spare logic board, so I put that in and I get the same problem.  What am I missing?  Any help would be appreciated.  It may be useful to know that I am a computer repair technician (I do component repairs at a motherboard/logic board level).  However, I believe all the hardware to be working.  I think it may be a firmware issue, but I can't get it to keep a screen long enough to do any software updates.  Anyone have any suggestions?

    I actually considered that and replaced the inverter, as I couldn't find the cord to external display, but also to no avail.  Same thing happened.

  • Screen goes black randomly

    Hi everyone.
    I have a very strange issue on 2 different PCs.
    From time to time the screen goes completly black, and I have to wait about 2-3 seconds for it to restore the picture.
    Both have NVIDIA video card, one PC has GF8900GT the second GF7200.
    Both PCs running GNOME
    In both PCs the screen is connected via DVI port.
    One PC has Arch installed for about 4 months the second has a 3 days old installation.
    I also have a laptop with Arch (about 4 months) but I didn't expirience any issues there.
    I'm not sure what the problem is, but it really annoys me.
    I'll be very gratefull if someone points me in the right direction.
    Thanks in advance.

    Hello dhruid,

  • Screen goes black for 3 seconds in premiere CS5 every time I click

    This is the first time I run Premiere CS5... On a fresh system install.
    I suspect it's not playing well with my video card, a Radeon HD 4870 with 1GB Ram... Very standard stuff.  I am running window 7 64 bit with 12 gb RAM, a week old build. I have all the updates and latest drivers, sigh. After Effects CS5 runs fine, Maya 2010 runs fine, Quicktime runs fine... What gives.
    Here's what happens: I only need to launch Premiere, right away I get the problem. The screen goes black 3 seconds before the prompt to create a new project. Once I create the project, the application workspace comes in, but if I click any menu, drag a tool window (whatever they are called), the screen goes black 3 seconds then comes back. Its basically impossible to work...Huge drag.
    Update:
    The problem stopped after I went into the 'device settings' in preferences and set the device to 'none'....When I clicked on the device settings panel, my monitor went black, and there was a 'no signal' warning that came up, as if the DVI-D  signal was dead. I was able to restore the signal by hitting ctrl-alt-del which switched me out of Premiere onto the desktop. Clearly, there is some issue with video. I switched back into Premiere and was able then to set to no devices.
    I'm not doing any capture at the moment, but I can only pray that it's some sort of bug related to not having a device connected? I plan on bringing footage from a RED in the next month. I upgraded to CS5 specifically so that I could use more than 4 gigs of RAM and for the new features.

    THank you for sending this.
    I followed the benchmark directions, and I get an error at the final step
    when I run the script:
    line 99
    Error: path not found
    I tried for an hour different things, namely to re run the whole test
    procedure, deleting the output files, etc... he script is looking for
    something in the preview files that it is not finding. I think the procedure
    was written for a previous version, because the metadata settings are
    different in my version of AME, and I don't know how much that affects it.
    Also, AME increments the file names when it renders them so that I did not
    get the right output file names at the first render. I had to turn off
    incrementing and manually name each clip before rendering. The vb scricpt
    looks for these names, so I understand it is important. I can't figure out,
    however, what the script is looking for in the preview folder and not
    finding.
    After spending almost two hours trying to troubleshoot the script, I gave
    up. I can tell you tho that it takes about 6-7 minutes on my box to encode
    all the videos.

  • Screen Goes Black During Startup (after login)

    Hello,
    I have a 2005 Mac Mini PPC OS 10.4.11. This is the first problem I've had since purchasing the computer. This problem popped up out of nowhere. The screen goes black during startup just after I login into my account. I can hear the hard drive spin like it is finishing the startup process. The monitor power button blinks green.
    I'm using the digital video cable. I tried switching to the VGA cable but the screen then goes black before the login screen.
    The computer will startup in Safe mode.
    I've tried Disk Utility (repair disk and repair permissions), Techtool Pro, Drive Genius, ColorSync Utility, Reset Pram, installed latest OS updates, and even re-installed the System twice (once because I removed all the Extension files and then the computer would not startup at all).
    I've also tried removing cache files, plist files, startup files, preference files, and some or all of extension files.
    The only applications I have recently installed were QuickTime Pro and a .flv movie player; both about a week before this problem started. I tried to uninstall them but could not figure out how.
    What is the problem? How can this be fixed?
    Thanks.
    Richard

    Howdy. I have Had the same problem as you in regards to a ViewSonic Monitor and the Mac Mini. This is my post:
    Monitor failure when switching resolutions
    Using Displays with the Mac mini, Apr 1, 2008, Replies: 2
    Running 10.5.2 on Mac Mini G4 1.42 Ghz with ATI Radeon 9200, 32 MB VRAM and ViewSonic VX922
    When switching resolutions from 1280x1024 to 800x600 or vice versa, the monitor will cut to black and the power light on the monitor switches from solid green to flashing green. Only by combinations of powering down the mini and starting it up again with the monitor on or off will bring the monitor back to life. This problem makes it difficult to play World of Warcraft amongst other games. Any feedback in regards to this problem would be appreciated.
    Thank You!
    At this point, I am unable to switch Monitor resolutions. If I do, the monitor goes black, and I have to power everything down and wait a while before I can restart.
    I've resigned myself to not switching resolutions, but I'm wondering if you've had any luck.
    Thanks for your time!

  • Screen goes black constantly, okay with Windows

    My mid-2010 21.5" iMac has been having issues for a while now.  The screen goes black randomly.  This happens anywhere from once a week to once every two seconds for days on end.  I've done plenty of research and seen similar problems but no real solutions.
    Symptoms:
    Screen goes to sleep.  Shine a flashlight on it, can still see stuff, so it's just the backlight out.
    It'll either happen at startup, before the Apple logo, or after using for a while.
    Using a hot corner or keyboard shortcut will temporarily wake it up.
    If watching video, sound still plays even though screen is black.
    Had it in a 60 degree room with A/C blasting on it, no change.
    Tried resetting PRAM, SMU.
    Hardware test was fine, but I can't do this when it's not actually working.
    External monitor works fine.
    Really weird-  this does not happen with Windows XP.  It runs fine.  So maybe a software problem?  BUT, the problem occurs when booting from Install DVD.  So maybe not a software problem.  I was going to wipe and re-install but can't even do that due to it blacking out.
    I've had it in and they replaced the LCD, didn't help.
    I wish it would just permanently stop working so it'd be easier to figure out, as it is, the intermittent nature is driving me nuts.  Can anyone please help?

    I meant SMC, not "SMU".  Oops.
    billkline, thanks for the input, the fact that Windows works has really got me scratching my head.  That's when I went to reinstall OS X but couldn't when it blacked out on the Snow Leopard Install DVD.  Thoroughly confused now.
    Also, starting tonight it now hangs on the gray startup screen for thirty seconds before booting up.  This usually is a one or two seconds before getting the Apple logo. 

  • Screen goes black and I get steady beeps

    I have a 2004 HP Pavilion a600n, AMD processor with Window XP SP3 and 1 gb of ram. I have no viruses or spyware due to running McAfee, Malwarebytes, Spybot, Spyware Blaster, and Advanced System care.
    My pc starts fine, but after about an hour, the screen goes black, and I get a series of steady beeps about a second long. There are no short, long beeps. Just steady short beeps and a black screen.
    I am forced to shut down via the power button. When I try to restart, the beeping occurs again, and the monitor light remains orange.
    I will let my pc sit for a day or two, and I can start it back up, the monitor light is green then, but after an hour, the whole process starts over.
    I have no way of knowing if it's ram, video, or fans. My video is built into the motherboard.
    I will run PC Doctor and clean the dust out of the fans, etc.
    But I do not have a lot of money to just randomly go about replacing parts. Does anyone have any idea what is the  most likely culprit?
    Thank you in advance for any help.

  • Screen Goes Black and Hangs when browsing by Artist, Album, Song, etc.

    I'm having a fairly huge issue with Front Row:
    I can play video files (although their is a moment of hangtime between selecting a video and the video actually playing) and music files (if I choose the "Shuffle Songs" option), however, when I choose to browse my music by artists, albums, songs, genres, etc. my screen goes black and stays that way until I hit CMD+Q over and over until it finally quits. Furthermore, when I do play music via "Shuffle Songs" and quit out of Front Row, the music continues to play in the background and cannot be stopped, paused, etc.
    Is there anyone out there who can help me fix this? I love Front Row and use it all the time and it would be a shame not to be able to anymore..
    Thanks in advance,
    Corey

    I have a similar problem. When browsing music the screen goes to black or just freezes on whatever was beeing displayed for maybe 30 seconds to a minute before continuing. It happens quite often. I am running the latest version of Front Row on a brand new Mac Mini. I have a very large iTunes music folder (about 830 gigabytes of uncompressed AIFF files) running on an external FW800 drive. I tried repairing permissions and a number of Front Row and a few iTunes files appear in the list. However, when I run repair permissions again, the same files are still listed so obviously if they need to be repaired, it's not happening. I tried repairing the volume (no problems found) and repairing permissions from the Install disc but the result was identical.

  • When I click on video it is stuck on one tv show, when I click 'done' the screen goes black so I can't access any other video that I downloaded from iTunes onto my iPad 2. How do I troubleshoot?

    The video on my iPad 2 is frozen on a tv show, although it will play the tv show until the end. At the end, when I click 'done' the screen goes black so I can't see the other movies that I've downloaded. I've shut down a few times but it reverts to the same thing. How can I re-set the video feature or do what is necessary to get it working again?

  • My laptop screen goes black when i plug in an Hdmi cord

    Initially I had both my tv and computer off. I connected the dvi to the tv and the hdmi to the laptop and turned them both on. I had no issue using my laptop as i tried to sync the computer to the TV. However i must have accidentally hit something in the graphics options as my laptop screen went black. I unplugged the hdmi cord from my laptop and the screen came back up. But now for some reason everytime i plug in the hdmi cord to the laptop the screen goes black. When i take it out it the screen comes back up. Did i change something that is causing this to happen? Any help would be greatly appreciated. Thanks

    I have pretty much the same exact problem and setup as DaveA1.  I have a Toshiba Satellite Laptop C55T-A5123 which I just purchased a few months ago and when I connect my laptop to my SONY TV via the HDMI cable the screen on my laptop goes black and the TV says no signal.  It was working just fine up until about a week ago when I was watching a movie through my VLC player and then the screen flickered a couple times then video went completely out and I've never been able to get it to come back even once.
    Here's the specs on my laptop:
