Emac monitor goes black – slap brings it back to life

Last couple of days my emac monitor will just shut down and go black, just like an old TV tube packing up used to. It won't return on restart, but did return a couple of times after I took out mains lead from side of computer, let it rest, then tried again. However, today, this solution didn't work, but a tap to the side of the computer did get the screen going. I've read a number of different possible explanations for what might be the problem – everything from battery, to airport card to it's terminally ill, get a new computer, so don't really know what to do. Don't want to go and buy a new computer if all I really needed to do was change the battery. Any thoughts? Thanks in advance.

That's all good news. You have the later and better USB 2.0 eMac. However, the model is one containing groups of units affected by the logic board issues with bad capacitors. The logic board issues were most commonly associated with these serial number ranges:
G8412xxxxxx- G8520xxxxxx
YM412xxxxxx - YM520xxxxxx
VM440xxxxxx - VM516xxxxxx
[again, don't post your serial number here]
If yours is in the list, all you can do is keep an eye on it. Keeping it clean like you've done should help keep internal temps down and that may help longevity. The repair--if the shop can find an unaffected logic board---is nearly as much as a new Mac Mini.
If your board goes, and you are within driving distance of Salem OR USA, there is a shop that offers a low-cost repair of bad eMac logic boards rather than a replacement; it's much less expensive IF you don't have to ship a 50-pound computer round trip.
Your particular eMac can take advantage of newer, larger RAM modules that were not available when Apple engaved the specs in stone (Apple says 1GB max RAM). With the proper modules, you can increase RAM to a total of 2GB with two of these:
1GB PC2700 DDR 333MHz CAS 2.5 184 Pin DIMM
We have one of the above installed in my wife's USB 2.0 eMac alongside an original 256MB stick for a total of 1.25GB RAM and it's completely stable. However, you should get the RAM from the source I mentioned as they test in Macs. Similar RAM form a retail outlet may be PC-only.

My 27in LED monitor goes black, pops then comes back on

Brand new 27in LED monitor goes black, popping sound comes from speakers (I think) then comes back on. Plugged into my brand new Macbook Pro 2.2 GHz i7. Unplugged every thing and it still does it. Has most recent firmware. Just started after five days of ownership. Do I need to take it back to the Apple Store?

Had a second-hand TV once (I am cheap -- sue me). One day the screen went fritzy and the room smelled of ozone.
Ozone is a big clue with regards to electronic equipment.

I turn my iMac on and it starts ok but after a minute the monitor goes black

I turn my iMac on and it starts ok but after a minute the monitor goes black, sometimes it comes back on sometimes it stays off, this has only happened since Apple replaced the hard drive.

Then, contact the Apple repair station that did the work.

Mini ppc w/ beachball problem and attached monitor going black frequently

I am seriously considering replacing this mini. I believe as the poster yesterday concluded that the hard drive in this mini is on the verge of quitting. Reference beachball problem everytime any entry is made. I completely reformatted with zero overwrite and slowness was not cured. Drive is only about 30% of capacity. The attached monitor goes black (not to sleep) this will happen while data is being entered periodically many times a day. The monitor behaves perfectly when connected to another mini with same cables. I think there may be a video output problem. This unit is in a high demand area for making appointments, so I think it is time to replace although I don't want to because of software issues. I looked at external firewire comments, but so far I can't find the drives that will support being start up drives and the video out problem is still an issue. I have also thought of bringing my PPC iMac flat screen from home and upgrading at home, but it is 4-5 years old and I don't want to do this again in 6 months. Any comments will be appreciated. Thanks

Have you run the Apple hardware test on it? Or if you have Applecare, the TechTools Deluxe test? To run the Apple hardware test, insert the first OS X disc that came with the system, which should say 'AHT Version x.x' in small print on the label. Reboot, holding the option key down. Choose the Apple hardware test, click the arrow pointing to the right, and follow directions. Does it identify any issues?
If you click the blue Apple, and about this mac, does the memory show what it should be? If there were a memory issue with the RAM strip, where you were only getting reduced memory, that could contribute to the issues you're seeing.
A number of people with slowing systems, with frequent beach balls, have used OnyX to clean up their system, which has made a performance difference. You can get it from http://www.titanium.free.fr/pgs2/english/download.html . Run the activities on the maintenance and cleaning tabs, which may require a reboot. Does that help?
One other thought, which is a stretch ... did you upgrade to 10.4.11 through the software update function or by installing the combo update? If by software update, you might want to download the combo version, and install it after you use OnyX. Repair permissions, install it, and repair permissions again, using Disk Utility. It's located at http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx10411comboupdat eppc.html

My monitor goes black at different times

My screen goes black at varies times. Someiimes when I cut my computer on, the screen is black. Then other times it goes black after i have been on for a while. I know something is going bad but what?

, Hello and thanks for posting on the HP support forums. First question is. Have you tried the monitor on another system or plugged it into a notebook to see if you have the same issue. Normally if your monitor goes black when plugged into your computer and it is the problem with the computer. You will get a no signal message come up on the screen. If at all possible please post back with your full Model and Product number so I can pull the specs on the system and see what options it came with and find out the best way to search out what the problem may be. Here is a link to help you with this. HP Desktop PCs - How Do I Find My Model Number or Product Number? Here is another link that may be of help until you post back. HP and Compaq All-in-One and HP TouchSmart Desktop PCs - Screen is Blank after Starting the Computer Please let me know how things go and post back when you get a chance. Thanks again for the post and have a great day.

ITunes7 corrupted your iPod? Here's how to bring it back to life:

Here is the only thing I have found that brings mine back to life:
Find a LiveCD Linux distro that has gparted on it. I have been using Puppy Linux, but found that the gparted project has also built a streamelined LiveCD image. (Check it out at http://gparted.sourceforge.net/livecd.php. Next time I will try it instead.)
Once I connect the iPod under Linux, I can run gparted and display the drive and partition configuration. I have found that when the iPod is corrupted, gparted does not recognize any partitions on it. When I go to create a partition, it instead prompts me to set the disklabel (say whether THE DRIVE ITSELF, NOT THE PARTITION, is msdos, mac, etc.). If I choose msdos (what it should be), nothing happens. If I choose mac, then it sets the disklabel accordingly and I am allowed to create a new partition.
Instead, I then change the disklabel back to msdos and recreate the FAT32 partition, shutdown, reboot to Windows, and presto the iPod is now properly read by Windows and iTunes.
When the iPod fails again, rinse and repeat.
Personally, I will not be reconnecting my iPod AT ALL until I see that there is a fix. My iPod ran perfectly fine for TWO WEEKS after doing this procedure. Then I connected it to add a couple of new albums and I had to go through this process all over again...
Hope this helps you bring your iPod back to life!
For further explanation:
A disklabel is a file at the beginning of the disk that indicates where each partition begins and how many disk sectors it occupies.
It appears as though iTunes 7 is corrupting the disklabel, and this procedure allows you to rebuild it. The problem with the formatting utilities under Windows is that they are dependent upon that preexisting disklabel and can't properly reformat the partition because the corrupted disklabel incorrectly offsets the partition.
Perhaps someone at Apple can confirm this and/or use this information to help fix the problem...

To enter recover mode:
1. Turn your phone OFF. If you can't turn it off, FORCE a turn off by holding down the Power and the Home buttons together for 5 seconds.
2. While your phone is turned OFF, HOLD DOWN the Home button. Keep it held down.
3. Connect your phone to the USB cable on your computer. KEEP the Home button held down during all this time.
4. Keep holding the Home button down until you see the iTunes/restore screens appear on your computer and your iPhone.
Apple needs to fix this application installation/upgrade thing ASAP! I've had to restore my phone FIVE times after installing applications and/or updating. This is nuts. I really love the iPhone, but come on Apple! Fix this terrible problem!"

Display monitor goes black after iMovie 3 opens up

Please help if you can, I hope it's not the monitor!
Every other application (including FCP and FCPHD) is working great, no problems with displays or anything, but as soon as I open iMovie and I click on any window in Edit mode, the entire screen goes black.
I am using eMac 1.25 GHz G4 with 768 MB of RAM and I just recently upgraded operating system to Tiger 10.4.8 I believe and to the latest Quicktime.
Please advise. Thank you.

That was a new one.
Various "weird" behaviour is caused by a bad preferences file.
Quit iMovie.
In the Finder, go to:
Users:YourLoginName:Library:Preferences
Delete the file: com.apple.imovie3.plist
Try iMovie again.

HDX18T Monitor Goes Black

For the past week or so, I've had to move the power plug around to get the laptop to charge. I determined that it's not the cable, but is the internal part. Today, when I opened the lid to bring the laptop out of sleep mode, my desktop displayed for a second or two, and then went blank. I've re-started several times, removed the battery and held the power button, but it doesn't help. Originally, it would go blank as soon as Windows started to load, so I tried Safe Mode, with the same result. Now, when I turn on the laptop, I might see the HP logo and/or the blinking cursor, and then the screen goes black.
I hooked it up to an external monitor, which worked, until I tried to uninstall the display driver, in hopes that it would correct itself, now I don't get anything on the external monitor either.
I suspect that it must be the graphics card, but not sure. One other thing that happened occasionally, if I bumped the side of the laptop, near the HDMI and USB ports on the left side of the laptop, against something metal, the screen would go black for a split second. Seemed like an electric short.
Thank you for any help you can provide. I'm okay with replacing parts, although not my favorite. I did replace the keyboard with the lighted keyboard a year ago.

That's too bad that the lamps are gone, but here are some alternatives.

The new screen is probably the best way to go, but removing it from the bezel is a challenge, after the hinges are removed, the screen is still held in there with this double sides sticky tape. If you use a very hot hair drier, starting at one of the upper corners, the adhesive can be softened enough to begin prying the bezel away from the screen. It takes awhile for the hair dryer to soften the adhesive so give yourself lots of time for this procedure.
When the new screen is installed it's very difficult to get every last crumb of debris out from under the bezel, so keep this in mind.
Another option is to replace the bulbs, I tried this ounce on an old screen that I didn't care about and it did not go well. I could not separate the parts that were taped together without damaging them. This would be the least expensive way to go if you can remove the bulbs.
I am also assuming that it's the 1920 X 1080 screen with the dual lamp arrangement _ some of them used screen with lower resolution with one CCFL lamp. (Yours is probably the dual lamp assembly)
There is also a used complete screen assembly available on e-bay, but eventually it may succumb to you fate in a few days or a few years, there is no way of knowing.
The part number for the complete display assembly is 498166-001 and it is available from HP, but it's expensive.

The other thing that I have not mentioned is that it may a faulty cable, perhaps the wires that supply the voltage to the inverter board have become internally frayed. This is a common occurrence, but usually this also effects the picture as well.
Here is the part number for the cable 496876-001. These can be found on e-bay and some of them are new.

I upgraded to Mavericks and my iMac monitor goes black randomly, but my attached cinema monitor stays active. I can fix it by putting it to sleep and waking it up again. But often it happens immediately after.

I have a 30in cinema display attached to my iMac and the iMac screen randomly goes black while the cinema stays active. I can put it to sleep and log back in which fixes it, but often it happens again immediately after. Sometimes it happens so quickly I can't even finishing logging in! I'd like to know if this is a Mavericks issue and I will roll my machine back. Thank you!

Wanted to update you on my situation with this.
So far 8 hours have gone by and I have not had a screen blackout.
FIRST I did the Hardware Test. TWICE on the extended test, the instructions on the KB Article explain. It took almost 3 hours, but while the test was running, both times, my computer screen did not go black.
I did get an error message, both times. Different each time. I looked up both of the error messages on discussion boards. Lots of conflicting info
One good thread said my first error was that my hard drive was bad and would probably fail.
The next error message I researched said that a fan was bad or needed replacement.
(information comes from other folks on discussion boards, not from Apple or technician)
Not sure what exactly those 2 error messages indicate but I followed a thread where someone found a solution by doing the following. So far it's worked.
After Hardware Test I did a shutdown and an SMC resest. Unplugged computer power source from wall and computer for about 10 minutes.
Finally after a restart I downloaded "SMC Fan Control" (CNET Downloads has a nice safe copy you can download)
There is a temperature monitor and from what I've read so far, keeping the CPU temperature under 50˚C is ideal. Making sure your fans and computer is in a well ventilated area/room too of course.
The SMC Fan Control helps you set your own speeds on the fans and so far everything has been going normal.

Hp2010i Monitor goes black after a second or two

When I power on my desktop the monitor comes on for a second or two and then the screen goes black. I tried powering off the monitor and then back on and it goes black again after a second or two. I've checked all cables and connections and powered the complete system off for several minutes. The computer itself is setting up properly -it's just the monitor giving me problems. Suggestions?

Pavilion 22bw monitor goes black

I recently purchased a used 22bw monitor. It has the appropriate 12V power block with correct
amps power block as per the label on the monitor. It works great for a few minutes and then goes black.
If I remove and reinsert the power input from the power block it comes back on and works ok
for another few minutes. Could just keep doing this but that would be a bit lame. The system I
am using is a Lenovo I-5 without a seperate video card and the Windows 7 Pro OS. I have turned
off all sleep settings in Windows and in the monitor itself but it still goes black after a few minutes
no matter whether I am watching video or just typing. Could this be a bad power inverter. I have
fixed other lcd monitors by replacing capacitors but I doubt that is the issue here. Any ideas?
Thanks very much.

Hello @STASC,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that you are having issues with the HP Pavilion 22bw Backlit Monitor not staying on. I am providing you with some steps for you to try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
If the issue persists after this you can try the monitor on another computer to see if it continues. If it does it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

Monitor goes black after apple logo startup

My family gave me a macbook pro 15 inch laptop. they bought it back in aug 2007. Everything has worked fine they told me until my sister had gotten into a small fender bender. But it was enough to send the laptop flying into some stuff in the back of the car, and dent the bottom of it. the problem is that the lap top starts up with gray screen and apple logo, then goes black, but the computer is still running. Also, if i hook it up to a external monitor, it works perfectly, as in it shows up on the external monitor. the dent is located on the botoom right hand corner if your looking at the computer head on. Also the computer gets hotter than usual. Any ideas on how to fix it? I'm a PC guy usually but would like to delve into macs also, so i would like to get this working. I'm running lepoard snow. Thats all i really know about it, any suggestions? I took it into the apple store and they said the logic board could be shorting out because of the aluminum hitting the logic board where the dent is. but if that was true, why would i get a display in the first place? any ideas.
Thank you for suggesting anyting, because it would help.

Welcome to Apple Discussions!
There are a couple of sites with teardown instructions:
http://www.ifixit.com/
http://www.powerbookmedic.com/
Both of these sites also have some troubleshooting tips.
If it were mine, I'd take it apart and straighten out the bent metal. Also check the internal cable connections--it's possible the flex cables to the display may need to be reseated. The connections to an external display are different from the connections to the built in display, so the external could work even if the internal one did not.
It actually sounds like it survived the crash pretty well since it still boots up and runs. The shock may have dislodged some cables, and you need to check and see if the fans are working. You can download a widget from the Apple site called "iStatPro" which will display fan speeds and temperatures.
Did you get the system discs? If so, you may be able to boot to the Apple Hardware Test. If you can, run the extended version and see if you get any error codes. Not sure if you can run it using an external monitor, but it may be worth a try.
Post back if you have any questions. Good luck!
