Satellite P10-504 shows just a black screen

Currently my Toshiba is acting a little odd. It boots and runs fine except there is no display on the LCD (I am currently using my TV as a monitor). The screen is on, but its black oddly adjusting the contrast (using Fn+F6 & F7) changes the shade of black slightly. The is no display in either Windows or DOS whilst booting.
Any help/suggestion would be appreciated, Many Thanks Chris.

Hi,
sounds a little stupid, but did you tried to unplug the tv from the machine and to check if encounter the same problem without the tv?
Otherwise I would suggest you bringing your machine to an local servicepartner for hardwarecheckup, because it can be that your screen is malfunctioning.
Try it and give some feedback. :)

When I open bookmarks the actual sites sometime do not show just the black screen with the safari icon while others show the actual site how can I see the actual content

I use Safari Mt Lion and when I view Bookmarks, the entire list of bookmarks show uo but on the display portion only the black screen witht the Safari icon shows while other bookmarks show the actual photo of what that bookmark is so unless I click on the bookmark on the blank ones I can not see what it is, it is inconvient because I have hundreds of bookmarks and I can not remember what I was bookmarking it for unless I can see it

Hi
I understand - sorry to have missed your point before now.
Some sites don't display those previews in safari - secure pages (https) for one, and also sites that are redirected.
Taking the example in your screenshot, the site http://fabulouslyartsy.blogspot.com/ actually redirects to http://www.fabulouslyartsy.com/ and Safari (rather annoyingly) doesn't 'follow' the redirection & show the appropriate preview. See the image below - the blank preview is for the blogspot address, and the one visible to the right is from going directly to the site.

HT1430 My iPhone 4 will not power on. When connected to iTunes it shows battery at 100%. Pressing and holding the sleep/wake button does nothing; just a black screen.

My iPhone 4 will not power on. When connected to iTunes via my computer, it is recognized and shows fully charged battery. Pressing and holding the sleep/wake button does nothing; just a black screen. Any suggestions?

Only way is to bring it to the Apple Store and use the warranty if it hasn't expired

ITunes purchased shows do not playback just a black screen

My wife and son are leaving tomorrow to ME. We purchased ~1$12 worth of shows. They playback in iTunes application but do not playback on her iPod video 30GB and she is running 1.1.2 firmware.
You can select the video and feel the drive queueing it up but just a black screen is displayed. I have other videos I have converted myself and they work fine.
Any ideas on what causes this?

Hi Lisa 1952,
What have you done so far to try to fix it? I've tried rebooting several times and it did not work. Tried connecting to iTines but it does not recognize the iPhone.
My other iPhone 4s restarted successfully after the updgrade but some apps don't function properly. It automatically closes while in use.
Apple please help. I know it's the weekend but I need the other iPhone to work. Can't use sim with a diffrent phone because it's a micro sim!

Connect the iPod to a charging source and then try the will not turn on topic of:
iPod touch: Hardware troubleshooting
If you have a 2G iPod and did not have the iPod connected to a charging source it is likely that the battery fully drained before the erase was complete since it can take hours to do the delete.

Keep iPhone on wall charger for ten minutes, it may turn ON itself. If still nothing, keep on charger and Reset, hold both home and power buttons for about 20 seconds until the iPhone begins to respond.

Did you ever figure out how to turn your phone on? Mine died today around noon for no reason. I'm so mad at it! I can't get it turned on, and I KNOW the battery is charged. Suggestions? I'm going to the genius bar (another trip completely out of my way) tomorrow morning. Suggestions?? Oh and please don't tell me to hold the "home" button and the "power" button together because I've been doing that all day. It doesn't work.

Satellite Pro C845-SP4337KL Windows 8 black screen and only mouse's cursor works

Hi,
In one Satellite Pro C845-SP4337KL with Windows 8 is happening that a black screen appears suddenly and only the mouse's cursor works.
If I connect a second display I have tow (2) black screens.
Control-Alt-Delete doesn't work.
If I move the cursor to the left corner the start menu doesn't appears.
The C845 responds throug the network to ping, and I can brow the disc remotly from another PC when the black screen appears.
The only thing I can do is to force the shutdown, and I lose my work.
After that I have to verify the disk integrity and try to recover my files.
This had happen twice.
Thanks for any help.
Cordially, Rafael Travecedo

When I open my photos app on my brand new iPhone 4S it's just a black screen. Why is this happening? Can someone please help?

The picture app won't open and when it does it's just a black screen. I have pictures saved buy I can't view them. Please help.

Try to Reset your device.
Press and hold both the Sleep/Wake button and the Home button for at least ten seconds, until the Apple logo appears (ignore the Slide to Power Off option that shows up first).
Web links to the user guide came with the iPhone.

Hello this is for sure software problem with the new ios I had lots of customers with the same issue your having that the shutter will get stuck or just a black screen etheir back camera or front camera won't work with this update. The only thing to do is wait for another update.

N97 camera won't start(just a black screen)

My N97 camera won't start just a black screen this issue since the update to the new firmware

ooooooooops so sorry about this, here it goes and start with the first code.
With all these operations I recommend you TAKE OUT MEMORY CARD and DO A BACK UP OF YOUR STUFF!!!
1. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list. The default code for ALL operations listed here is 12345
2. *#7370# - Reformat your phone (out of the box, tho keep in mind that most newer nokia phones at least n series, e series and s60 based phones have udp - user data preservation so not ALL data may be lost. still it is a good idea to always do a back up of your stuff.)
3. This you perform as a last resort. Nothing else is working.If the phone is not showing any activity, proceed with hard formatting , turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
hard reset - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons ( for Nokia 5800XM - use the following buttons to do a hard reset, GREEN/RED/CAMERA keys pressed all at once on power up. this will only work on 5800's that have firmware version 20... and up. ) For Nokia N97 (unofficial version but works) is SHIFT /SPACE BAR / BACKSPACE while holding the power button. Again do not let go until you see the handshake screen.
If these codes are not working the only thing for you to do is contact your Nokia Care Center/Service for assistance.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
