HP 2509b Monitor starts out and goes black.

OP Windows 7 64-bit
My HP 2509b monitor flickered on and off ... I restarted my machine ... the monitor came on, then slowly went black. It does this on my husbands computer also. The spare monitor I have hooked up works great ... but it's not my HP 2509b. I have owned it a little under a year.

bperigo,
This is a very well documented issue of this monitor. Searching the forum yields at least 80 threads containing "2509m".
Please shine a flashlight at the front on the screen at various angles and look a faint image on the screen. If you see an image that corresponds to the output of your computer, your backlight inverter and/or lamps have gone bad.
Concerning the menu options, again shine a flash light at the screen and look for the menu image. If the backlight inverter and/or backlight lamps have gone bad, you will see no image without an external light source because the monitor isn't producing it's own light as it should.

Why is my 2007 HP V17 monitor screen flickering and going black?

I have an old 2007 HP V17 monitor attached with a VGA cable to an early 2008 Macbook running on OS 10.6.8 software via a DVI- mini connector (this is also my desktop computer).
About 6 months ago, the HP display started going white and sometimes gray for a few seconds before the image would return, and a couple of times I had to unplug it and restart the Macbook before it came back. I followed Apple's instructions for testing whether the problem was in the computer (= resetting the system by resetting the Mac's parameter RAM and SMC), but the computer tested okay. I then purchased a new VGA cable and DVI-mini connector, but the problem persisted.
Today the HP screen suddenly went black (first time going black) and stayed black. The power button stayed lit and if I pressed the Volume or Auto buttons, the "Volume" etc. message boxes did appear, so the device's backlight is apparently working and not burnt out (unless the backlight has nothing to do with the message boxes showing up, which for all I know may be the case). However, the Desktop showed up only on the Macbook.
I checked all the connections, removed the DVI connector and plugged it back into the Macbook several times, but the HP screen stayed black, so I removed the DVI connector in order to type this message on the Macbook. Then, as I was writing this, I decided to plug it back into the Macbook one more time--and sure enough, the display is back!
I love this monitor, which is the perfect size and ergonomic height for my setup, so I'd hate to have to replace it. Can anyone tell me
Given the information above, what's the probable reason for the flickering and going to black? If it's the computer, what could it be? Can I solve this problem myself? (See above; I couldn't find any other ways to test the computer in the Apple articles database.)
If not, could a monitor this old be repaired?
If so, how much would repairing it cost, since buying a new monitor that I probably wouldn't like as much would cost upwards of $300?
Thanks so much for any advice out there!

Hello @turtlewiz,
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 your HP V17 Monitor has gone black and is not displaying anything. 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.

Flickers while starting up, and goes black

PB G4, 15-in screen. On start up, the screen begins to flicker, and goes completely black by the time the machine is fully running.
I've hooked an external display up to the PB, and it works just fine, so I'm thinking the graphics card is good. Bad LCD? Inverter? Opinions!

After boot, shine a strong light on the dark screen, and see if you see the desktop faintly, or shine the light thru the Apple logo on the lid. If you see the faint desktop, then it should be the backlight that's bad. What is harder to determine is if it's the inverter or the lamps.

My ipad keeps cutting out and going back to start up screen, my ipad keeps cutting out and going back to start up screen

my ipad2 keeps cutting out and going back to start up screen?

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without be charged again. Also, if you have IOS-7, read this.

T40P Black screen or fuzzy colors and goes black

I recently have this probpem. My laptop will go black but still running or fuzzy and starts to fade and goes black but if I lift it up and tap it down softly on the desk the screen comes back up(sometimes). I read somewhere it could be a loose cable which makes sense if I move or tap it and it comes back on. Anyways this is happening more often. I am wondering if I get a monitor to use for the short term will it solve the issue. I have work to get done in the next month. I did have to reload all my software in April and thought it could be a driver but agian tapping it makes me think that is not it. I called an IBM repair shop and they could not fix it within a week and I need it so I am hoping a monitor is a short term fix. Any solutions? I can buy a new laptop but would like to fix this one and have as a backup if possible. I am not tech savy-I do accounting and need the info on the laptop to finish some jjobs. Also-can I just take out my drive and put in another laptop? 2373-G3U thanks

Hello mkandziora,
the incident that your display goes off by moving your unit, seems to point to a problem called flexing.
The mobo flexes and the gfx chip, soldered on mobo, became loose and you´ll need a new mobo.
In euro´s 150,-.
It´s a more common problem of T4* series.
Kind regards
Andreas

I am having problems with my computor freezing and going black screen and then coming on again,

I'm trying to make a ring to for iPhone and about 20 sec into the playing of the song it fades out and goes silent. What am I doing wrong? Thanks

Im not sure what garage band is, but i can tell you the way apple recommends making ringtones. Highlight a song in iTunes, right click and select get info. Goto the options tab and youll see the time lengths (write down the ending time) for the start time type in where you want the ringtone to start, ringtones can only be 30 sec long so make the ending time 30 sec later. Exit it out of the info and while song highlighted goto the "advanced" tab at the top of iTunes where you will see an option that says "create aac version". after creating the aac version you will have a duplicate song in your iTunes, change the original back to the correct time length. Take the 30 sec aac version and drag it to your desktop, right click the icon and click "preferences" You will then be able to change the name of the file which will be somethign to the effect of "songnamehere.m4a" you just change the m4a to m4r. you now have a ringtone, drag the new file to iTunes where it will pop up in a new tab labled ringtones. If you cannot change the name of the file when it is on your desktop let me know and i will give you instuctions how to be able to change it. Once you get it figured out you can use any song you have on iTunes to make a ringtone.

I have an original iPad. As I'm using it the iPad throws me out and goes back to home.

I have an original iPad. As I'm using it the iPad throws me out and goes back to home. This happens from different apps and from Safari.

This might help for a while and if you do it from time to time, it might continue to help.
Clear Safari, close all apps on your iPad and reset the device.
Go to Settings>Safari>Clear History, Cookies and Data.
In order to close apps in iOS 5 or iOS 6, first tap the home button once. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button twice.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Phone vibrates 5 times and goes black, only fully boots while plugged into USB at splash screen

I have an HTC Droid Incredible with stock firmware 2.2 and it will no longer boot properly. The phone is not rooted or altered in any way.
When the power button is pressed, the phone shows the HTC Incredible splash screen, vibrates 5 times, and the screen goes black and the LED light flashes green over and over until the battery is pulled out.
Strangely enough, if the phone is plugged into a PC via USB or a charger during that splash screen for a few seconds (at least 5), it DOES boot up to the OS and seemingly works fine, but the SD card and internal storage is listed as "unavailable". I can also access the HBOOT menu by holding volume- while turning the phone on.
The phone then functions until the next time it needs to be rebooted, or if you attempt to plug it in via USB again (only when attached to a PC) and remove it, then it vibrates 5 times and goes black once again. If you repeat the battery pull and USB plug-in process it works again.
I've been able to successfully return it to the factory setting, reflash the stock ROM via SD from the HBOOT menu and from a RUU from my PC, but it doesn't fix the issue. The SD card has been reformatted properly and error checked and can be accessed from a card reader... just not while it is in the phone.
Pretty weird issue that's driving me crazy.

This reply in that link is what I am suggesting should have been implemented in the Droid 4:
“Just adding my 2 cents. Found this to be odd with my new phone. Previous WM6.1 phone I would sync and charge overnight with my PC and let both 'sleep' when done. WM6 must be closing the port when the USB power drops so not to deplete the battery.
Just one more quirk with the new device.”
There is no reason for current leakage into a sleeping computer because of keeping data lines open. It should be easy enough to shut down the usb port when a voltage drop is detected in on the power pins. In any case, hopefully my posting will at least alleviate some anxiety for someone down the line. The procedure gets the phone back up and running in an expedient manner. Thanks for your research.

I have an iMac. , mid 2007. Frequently, when I take an action, the little color wheel starts spinning and goes on for quite awhile. Save a file, close a file, open a file, open a window, it's all random. Somtimes it stalls, sometimes it doesn't. Why?

Consider adding more memory. Be sure you have adequate free space on the hard drive - 15 GBs or 10% of the drive's capacity, whichever is greater. Do not run too many applications concurrently. Visit The XLab FAQs and read the FAQ on resolving the SBBOD.
Do some maintenance:
Repair the Hard Drive and Permissions
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

When i press the on/off my ipod show me the lock screen only half second and goes black.

When i press the on/off my ipod show me the lock screen only half second and goes black.
I try again and works normally. Sometimes do that.
What Happens?

Try the standard fixes:
- Reset. Nothing will belost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod.

IPad screen locks itself and goes black when nudged? very frustrating

Hi, my IPad is driving me nuts! Can anyone help please?
I can be in the middle of anything ( games, apps, typing, banking, etc. etc.) and with the slightest movement or nudge - the screen locks itself and goes black??
I then have to press the home button, slide to unlock it - and it opens back up to exactly where I was.
This happens constantly, and is so frustrating!

Is there a case or screen protector that is possibly interfering with the proximity sensor (detects if the phone is near your face, allows the keypad/screen to be visible when the phone is away from your face)
