TS3700 music stops playing when the screen goes dark, but the earbud jack is flush with the iPod. The Jack is hard to push in now. what is the problem?

Music stops playing when the screen goes dark; the earbud jack is flush with the iPod. The Jack is hard to push in. what is the problem? How do I Fix it?

And you are positive the white part of the headset is flush with the body of the Nano?
Have you tried another set of headphones to see if the problem persisted? If so, it's likely that the headphone jack needs replacing.

Screen goes dark with the slightest touch

Okay, so my screen went dead on my ibookG4, but I was able to physically manipulate the display and it would come back to life for a minute or two.
So I took it to the repair shop- 1st they replaced the inverter board with no success. 2nd, they charged me $400-plus labor for a new LCD.
So I go to pick up my machine at the shop, and the repair guy brings it out and fires it up, while I'm talking to him, the screen just goes dark. I said to the guy that something is still wrong, but he assures me that the computer has just went to sleep- B.S.. I tap on the keys trying to wake it up, but I have no luck... The repair guy taps on the power button, and it miraculously comes to life.
Cool... or so i thought.
So I take it home and open the lid. I go to adjust the screen angle and as soon as I touch the display it goes dark.
So now if I touch the display, or breathe a little bit too hard in the direction of the computer, the screen goes black.
I payed over $600 to fix this problem, and I think the repair-shop charged me for parts that didn't need to be replaced. Any Idea what could be causing this problem?

Okay, admittedly I don't have your unit in my hands. But, the instant, long distance, I've never actually seen your iBook diagnosis is that the issue is caused by a damaged inverter and reed switch cable assembly, pinched as it passes through the hinge from the lower case to the display, and therefore intermittently open.
It's actually a very common problem. And, if that is the case, it's pathetic that a certified technician missed it. It's also possible that it's a damaged display cable, but that is far less likely.
Although a limited number of early iBook G4 models—in rare circumstances—may have been affected by the separation of a ball-grid array video chip from the logic board, that issue is limited almost completely to iBook G3 models.
iBook liquid crystal displays have backlights built into into them, and backlights display binary behavior: they either work or they don't work. They do not intermittently work. That's a primary clue that it is the interruption in current to the backlight because of an open cable, combined with movement of the display and therefore the hinge, that suggest that the cable is the culprit.
Apple authorized service operations must meet technician certification and service excellence metrics to remain so, and to be reimbursed in warranty service events. They pay a serious penalty for not getting repairs right the first time, even under circumstances where additional issues are masked by a single defective part and where the subsequent issues aren't discovered until the first part is replaced.
If you do not believe that you have been treated appropriately or fairly, Apple has provisions to address your concerns. Your initial move should be to return to the same service provider, ask that the problem be properly resolved, and that you not be charged for the inverter and display assembly that were not required to properly effect the repair. If you cannot negotiate that outcome, contact me by electronic mail and I will outline how you can take additional steps to resolve the matter. The first step, though, is to return to that dealer, who should take the necessary steps to complete the repair properly, reimburse you for the parts not required, and likely refund a portion of the labor fees charged so far. That advice is based solely upon your representation of what has happened so far, but it strikes me as a reasonable one.

Screen goes dark when the computer is turned a specific way. Have to pick up the computer and move around in order to get the screen back on?

Occasionally when I turn my computer to show someone something the screen goes completely dark. Then I have to re-turn it or move it around to try and get the screen back on. Its not automatic dim because that is turned off. There doesn't seem to be any kind of pattern either. Help please!

Blackberry screen goes white in the middle of a video?

Hi guys, I have a problem and I seriously need some help. I got my blackberry about 4 months ago, and I watch a lot of youtube videos on it. But suddenly about 2 weeks ago. My screen turns white halfway through the video (about 2-3 mins). As first I though it could be the battery is finished, but even after it's on full charge it'll do the same thing! Everytime it happens, I have to take out the battery and insert it again to get it working. This has become really annoying! Please help?

Hi Ince123
You are corect If problem still presist then I would first arrange a Good battery to see if its a battery issue, then the next step will be be a OS reload to rule out any Software issue, But before going for a reload do a backup of your device :
KB12487 : How backup BlackBerry smartphone Data using BlackBerry desktop software for Windows
Once it is done you can perform a OS Reload :
KB03621 : How to Reload BlackBerry Device Software and application using BlackBerry Desktop Software
So please try it and see if that help in resolving your issue.

IPhone 3GS screen goes dark...no apparent fix for it

My iPhone 3GS has started having a problem where the screen goes dark. The phone is still active and if you have the right light and strain real hard you can barely see the icons. I have tried everything I know to fix this but nothing works. One thing that did work for about a day was a Reset All Settings, from the General Settings menu. Previous to doing that, I have tried: 1) turn it on and off, 2)hard reset, 3)restore from iTunes. None of these worked for more than a few minutes. I did restore firwmare from the computer but I have not tried putting the iPhone into DFU mode...is there a difference?
Any ideas appreciated.

All iPhones require a SIM for updating/activating.
The SIM does not need to be active, simply insert a SIM card and activate the device. Borrow a SIM from a friend if necessary.

Screen goes dark, computer makes ticking sound

I have a 17" 1.33 GHz Power Book G4 running OS 10.4.11 with 1 gig of DDR SDRAM. I have picked up a strange casualty after the last up grades. The screen goes dark and the computer makes a tic, tic, tic, sound. The power is still on. To recover I have to turn the computer off and reboot. (sounds like a PC!) It just started doing this.
Any help is appreciated.

It's quite likely your hard drive is failing.

My screen on my iMac 2008 goes darker in the top 1/3, readable but why?, My screen on my iMac 2008 goes darker in the top 1/3, readable but why?

The screen on my iMac (2008) goes darker all the time in the top 1/3 of the screen. It has been doing this for the past year. It's readable but just. Is there anything I can do to correct this or is it just the screen is dying?

Either the display or graphics card is in trouble. Run Apple Hardware Test in extended mode three times back to back. If errors appear then a hardware issue is confirmed, the next step would be to take the machine in for repair. Because the machine is 6 years old now you may want to consider looking into a replacement for it.

Screen Darker In The Middle

I have noticed that the screen is much darker in the middle of the screen, vertically in a column. This was improved when i booted to the CD. Now on a fresh install and it looks better but doesnt seem to be completely fixed. I am going to wait and let the screen heat up. Also is there any fix for the high pitched noise yet?

hmm...I just received mine literally 20 minutes ago, and my screen is considerably darker on the right side (especially along the right edge). And I have this backlighting leaking on the upper right corner. I am going to wait a day and see if that clears anything. If not, it's going back....sigh...

When I power up my mac, I see the white screen and the apple icon. After a few seconds of powering up the screen goes dark. Yet I still can the mouse arrow but nothing else.

When I power up my Imac, I see the white screen and the apple icon. After a few seconds the screen goes dark. I am able to still see the mouse arrow as I move it around. But nothing else. What is the problem and how do I recover?

Try this from another user:
1. Shut the computer down by holding the power button for 10 seconds
2. Restart the computer and press shift at the same time until you see the progress bar start moving
3. Once you reach the point where your screen goes dark and you see the cursor, type the first letter of the username for your computer, then hit Enter, then type your password, then hit Enter.
4. After a moment, you should see the spinning beach ball
5. Your screen should then move on to something along the lines of "Completing OSX Installation" (I can't remember the exact wording). Let it finish. After that it should go to your normal desktop and the issue should be fixed. (If your screen goes pitch black during this process, hit the space bar. I thought it wasn't working, but the screen was just sleeping).

Hi
Try holding sleep/wake + power button for 10 seconds, until you see the Apple Logo.
See how that goes.
