Satellite M30X-111 screen doesn't display anything but external monitor works

My laptop screen just doesn't display anything (look like when the computer is off) but when I connect the external monitor, then the desktop will be displayed on that monitor. I tried to recover the laptop using the recovery disk and it worked again, but today, it stopped working again.
I again have to plug in the external monitor, and after I tried to reboot, I keep pressing F8 but the start up mode doesn't come up, only the sound of when you keep pressing a button for too long beeps, however, the laptop monitor works again.
How do I fix this problem?

Hi
According to your first posting I presume that LCD display on your notebook is defective. If you can not see BIOS settings or Toshiba welcome screen there must be some display problem.
Experiment with external display is to be sure that graphic card is not responsible for that. In your case it works with external display and graphic card can not be responsible.
Like I said try to enter bios settings and report if you can see Toshiba welcome screen.

Screen doesn't display anything. GT70

Me as a few other I have seen on the forum is having the problem were the laptop simply refuses to use anything but the Intel HD 4000 video card. I tried several different maximum performance settings to no success. I went into my device manage and display manager to see if the computer even knows it has the GeForce GTX 670m video card. It acknowledges the video card and I thought. If i disable the Intel HD 4000 it has to use the GTX 670m right? WRONG. The screen went completely black and refuses to display anything. I have absolutely no idea what to do now and need your help. I have tried hooking it up to another monitor but still nothing.
I dont understand in the first place why it refuses to use the graphics card I have paid for. Without it it has the same performance as my 4 year old 800£ computer I upgraded from.

Removing the HD4000 that is used for non 3d load display of course results in a black screen as the Nvidia is only meant for 3D load.
For the switching working make sure your notebook has SCM (for Win 8): http://www.msi.com/service/download/utility-19670.html and Nvidia VGA OC (for Turbo/Win8): http://www.msi.com/service/download/utility-19690.html or S-Bar (for Win 7): http://www.msi.com/service/download/utility-19324.html and Nvidia VGA OC (for Win 7): http://www.msi.com/service/download/utility-18804.html installed

Satellite A100 display blank but external vga works

Hello,
my two year old Satellite A100-847 display stopped working. I used external VGA monitor for a few days,
then switched back to laptop LCD and found out it doesnt work. It doesn't show anything , only the grey backlight.
The LCD doesn't work even at boot nor does in WIN XP, nor at battery power or AC. I have tried to dismantle the display according to some guide
to check if the signal cable is firmly at its place in the connection to LCD, but it hasn't solved the problem.
I use the original BIOS and somewhat updated nvidia display driver, they worked fine up to now, so I suggest its not a bios/driver problem.
(but maybe it is, so I tried to install original display driver with no effect. I dont want to try to flash new bios, and end up with f....ed up display and bios too)
The video output to external monitor is completely fine, from boot or in win.
Does anybody see a solution, please? Or should I only go to service provider...
thank you
Pepe

Hello
In my opinion you should definitely go to the nearest Authorized service provider. They can say for sure what the problem is and, of course, order by Toshiba the right part for exchange.
It is definitely hardware issue and it can be the FL inverter, especially if you see the something on the screen but almost black and grey.

My dv6700 screen is dim, displays correctly on external monitor

HI,
I have a dv6700 laptop that I am having screen problems with. The computer boots just fine, but the lcd is so dim you can barely see that it is on at all. The computer does display correctly on an external monitor. I have even tried switching the lcd out with another known working one and the second one did the same thing. Just to eliminate it, I did try the first lcd with another motherboard, and had no problems with it. I'm pretty sure I have my problem isolated to the motherboard...
Does anyone have any other troubleshooting suggestions before I conceed defeat and give up on this motherboard? I don't know if there are any settings anywhere that might help, something like that. Would the Windows display driver affect the boot up and splash screen? Bios is dark as well. Thanks in advance!

Take a look at this thread and see if it helps. You did look into your power settings on and off the battery?

PB display flickers, but external monitor still OK

Hi all,
I've just bought a faulty powerbook to see if i can fix it. It's a G4 15" 1Ghz Titanium DVI. The fault is that the powerbook display frequently becomes corrupted. it's actually a beautiful effect, but not very practical! Every few moments, minutes sometimes, the display looks as if deep colours are gradualy bleeding accross it, until it becomes unreadable. the effect is sometimes psycedelic and sometimes textured like oil on canvas!
Anyway, simply moving the angle of the display a little clears the screen and everything's visible again. At no time does the system crash or anything; if there's an external monitor conected in Display Mirroring or Extended Desktop mode it doesn't show any artifacts and continues to work perfectly. It's only the powerbook's own display that exhibits the fault.
i'm presuming therefore that the logic board is OK but that there is a loose connection somewhere (where I don't know!). Could it be the invertor board however?
does this all sound familiar to anyone?
thanks!
TiBook 1Ghz (DVI) Mac OS X (10.3.9) 9600/350

Hi, efunc. If your situation is such that you could happily use the Powerbook as a very compact desktop computer with its built-in display closed and an external monitor, keyboard and mouse connected, you might be able to do so for a long time without fixing anything at all.
If you really want to use the Powerbook as a portable, you'll have to crawl inside and look around for the trouble. The fact that changing the built-in display's angle clears the problem suggests strongly that the cause is in one of the very thin, fragile cables that pass through the display hinges. These can become pinched or abraded in the very narrow passageway there (especially if the hinges are fatigued and begining to break), leading to faulty insulation and short circuits or even severed cables. There is very little room there to make any repairs, if that's the case, and cable damage is not always easy to see. Replacing the cables, one end of which is sealed inside the display bezel, is essentially impossible. A professional technician, when faced with bad display cables, replaces the entire display instead of trying to pry the bezel apart.
Because the cables are so thin, flexible and delicate, the motion of the display being opened, closed and adjusted is, in itself, very unlikely to loosen (or tighten) any of the cables' connections inside the body of the Powerbook. But a loose connection there is possible, and it wouldn't hurt to check. Complete disassembly instructions are here, and will show you where the display cable connections are located.
If you don't find a bad connection, the inverter board is the least expensive part you could replace in the hope of solving the problem. But I doubt that adjusting the screen angle would "fix" (even temporarily) a problem caused by a bad inverter, so I suspect that isn't where the fault lies.
Good luck.
EDIT: Oh, dear — I just realized that you're the very same efunc who reports a whole different set of problems with his used 1GHz Tibook in a different thread. If all those problems are occurring in the same Tibook as the display problems discussed in this thread, most of what I've said above is out the window, and the source of all the problems could be anywhere, including the logic board, or even multiple sources.
My comments above were based on the assumption that the problem you reported in this thread was the only one you were having with the affected machine. If that assumption is wrong, disregard them.

When booting into my previously working Windows partition, the screen is not displaying anything. It was working before...

Im not sure what happened but I just tried to bootinto my Windows partition and the screen is completely blank. I dont see the Windows boot logo and I eventually here the startup noise. I have also been able to logon without seeeing the screen.
Ive done a PRAM and SMC reset and neither has helped. I suspect that a recent update on OS X may have caused video issues but I am not sure of it. All of my research has led me to a black screen during the install of Windows onto the bootcamp partition. Nothing delaing with an actual running Windows partition that just goes to black.
Any suggestions?

There is more than enough disk space available on the partition.
Booting from the install CD doesnt work because I cannot seeing anything.
Removed my install of Windows 7 via bootcamp and tried to reinstall but I got the same black screen (no backlight as usual).
BTW, OS X does affect the Windows install. If you update the driver for the say the video card, that means that the apple drivers that are needed to run Windows are more than likely to be affected.
Just like VMware tool running on a ESXi 4.1 host will need to be reinstalled on an ESXi 5.0 host. Same hardware but the tools on the VM need to be updated to reflect the host OS.

Macbook screen won't work, but external monitor works fine...

Hey guys - are there any solutions out there for this problem that doesn't involve hundreds of dollars? A mate of mine spilled beer on a macbook - had to pay for it, I fired it up and everything works fine but the screen... Is there a way that I can check the connections or dry something off? Apple told the owner to throw it in the bin - but it works fine plugged into a monitor. The screen isn't cracked or chipped - all looks fine - I'm guessing that fluid had got into a connection somewhere. Help me Gurus!
Cheers

Have you tried drying it without the back cover and upside down? l heard it worked for some guy

TS3274 dropped ipad now screen doesn't display

My daughter dropped her ipad and now the screen doesn't display anything. We can see some light changes but nothing else. It appears that the screen can still be touched to use apps because we are able to play music. Any suggestions on what we should do?

Not sure if you've fixed this, but it really works. After reading similar advice, I banged it on the corner of my couch and the display totally came back clear as day. Could not read it before.

MSI 970a-g46 motherboard starts up but doesn't display anything.

Hello, I'm having problems with a new motherboard I got from Amazon, specifically the 970a-g46. The following are my specs in use with this motherboard:
CPU: AMD Phenom 2 x4 965
GPU: nVidia GeForce 560 GTX
Ram: 8gb Kingston HyperX Fury 1866mhz.
PSU: Corsair 650TX (650 Watts)
Compatability-wise, everything checks out so I wasn't expecting problems at first. All the other parts excluding the ram I've used before. Here's exactly what happens:
I power up the computer after everything is installed and connected. The 4 phase LEDs turn on which tell me the CPU is powered up and working (so I assume). I don't get any beeps or buzzs mainly because I don't see any speaker/buzzer on this board. The monitor blinks and while it is connected to my GPU, it doesn't display anything, it's just a black screen. I can leave it on for a few minutes and I'll still not see anything happen. An important observation here is that my keyboard which has LEDs will turn on after a short period of time in boot-up (with my older set-up that is). This does not happen ever regardless of how long I leave my computer on on this new mobo.
I've gone over and checked/tested numerous things:
* The PCI-E and ATX cables for the GPU, motherboard and CPU are all connected and secured (I've tried both 4-pin and 8-pin connections for the CPU, neither help).
* I've tried jumping the CMOS multiple times to no avail.
* I tested the ram on another computer and it worked just fine on that one.
* I've tested the motherboard without a GPU and it still does nothing (though I think that's because this motherboard doesnt have its own integrated GPU for some reason).
So far the only possible reasons why my computer is not working is because of my PSU (very unlikely as it's only a year old and it's a Corsair, which I've heard is very reliable in the long-run), GPU (It is quite a few years old but even without the GPU my computer still doesn't go past boot-up), CPU (possible due to its age and how many freaking time I've reseated it (probably around 8 times) so I wouldn't doubt it, but before I put it into this motherboard I did check its pins and they were all there and placed nice and smoothly into the socket.) and finally the motherboard (it's possible that this is just a defected motherboard and giving me a super hard time which would be a first in all the years I"ve spent computer building).
The best case scenario of course is me giving some kind of oversight to how I transferred over the parts and connectors. I might've missed something obvious to please any advice/insight on how I can solve this problem would be greatly appreciated
EDIT: Some other things I did but forgot to mention:
* Checked ground nut things and ensured they matched the specifications of the motherboard ATX; only 6 are under the board and each one is aligned up with the holes on the board as designed.
* Tried booting up without powering the CPU. Only one phase LED light came on, still the same problem (for an obvious reason this time now).
* Re-seated GPU multiple times, re-connected cables multiple times.
What I have NOT done is re-seat the CPU because I am almost out of acetone so I would need to get another supply of that which won't be until tomorrow. I also have not re-seated everything back on my older motherboard to check if it still works. Tomorrow I'll most likely do that and if I find that the old motherboard works flawlessly then that tells me that the new motherboard I got is either defected or there's some compatability issue I"m missed out on.
EDIT 2: Just found a speaker and plugged it into the motherboard. Booted it up and I got no beeps whatsoever. So this mobo is giving me no video activity (there is a signal it's just blank), and no beeps from the motherboard. I have no idea what that could mean at this point.
EDIT 3: I decided to test a few things with the new speaker I just got. First I removed ram and tried running, I got 3 beeps which I assume is the beep sequence of faulty/no ram. Removed the power to CPU and the GPU itself individually, gave no beeps this time.

What's the serial number of your MB? Needed to determine what BIOS may be on the MB. Exactly which version of the CPU is it? There were several different 965 CPUs and they required different BIOS versions, 1.2, 1.9,2.2 depending on which CPU you actually have.
Also another problem may be that native memory supported by your CPU is DDR3-1333, not 1866
None of the supported CPUs have integrated graphics, any MB graphics would be in the chipset, not CPU. Examples would be 785G, 880G
Thank you very much rhradacut! The problem was that the mobo for whatever reason was forcing 1866mhz on my CPU when it only supported up to 1600mhz. I had to install a spare ddr3 module to downclock it so that I could access the BIOS and manually set the DRAM timing to 1600mhz for it to work. That's a very strange problem that I figured would've been auto-resolved by the hardware, and would also be a big problem if I didn't have any spare DDR3 ram to work with.
Once again thanks for helping out on solving my problem.

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

I'm trying to set up a dual monitor for my new iMac. I'm using a second display I used with my old G5. My iMac recognizes the second monitor but the monitor won't turn on. Power button doesn't do anything on the monitor itself.

If it won't turn on then the monitor is dead (power supply?, video circuits?). Not worth repairing.
If you have a new iMac then it has thunderbolt. So exactly what is that monitor you are trying to connect? For TB you can connect a mini-displayport monitor. Probably (not 100% sure with TB) can use dvi or vga too if you have the appropriate adapter.

IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black

IPhone black screen does not show anything, but I can hear that the device works. I hear the lock open the screen and hear the iPod but the screen remains black!!

It's happened to me before as well. Try holding both lock(top right) and home buttons simultaneously until u see a slight flash of wight then just reboot it normally. If that doesn't work try restoring your device from itunes

When I attach USB flashdrive to my new Mac Air no icon appears. I just finished downloading pictures off of old mac and that one worked as expected.The new computer doesn't show anything but when I pull USB out pompts message improper eject. Any ideas?

When I attached my USB flashdrive to my new Mac Air no icon appears and the same when I attached my new superdrive. I just finished downloading pictures off of my old Mac and that one worked as expected. The new computer doesn't show anything but when I pull the USB flashdrive out, a message prompts me with an improper eject notice. Any ideas on why no icon (a disc) appears and how can I get it to?

Open Finder preferences, click on the General icon in the toolbar. Check the boxes for what you want displayed on the Desktop. Click on the Sidebar icon in the toolbar and do the same for what you want displayed in the sidebar.

White screen, but you could get the display via an external monitor.

Hi,
A few weeks ago, my Macbook pro(A1212) stopped displaying. It only showed a white screen, but you could get the display via an external monitor. A friend looked at it and we discovered a burnt Mosfet (SI3443DV) which was item Q9400 on the motherboard. He went and changed it but it only displayed for less than 5 minutes and it went back to the white screen. would you please advice on what to do since i am not in a financial position to take it for repairs at the apple store?
Joe

Forget it.
1: If it was tampered with, then it doesn't qualify for warranty or AppleCare.
2: Repairing it will incur a new expensive logicboard, because that's how they do things. Swap parts out.
3: No money, means no Mac.
Sorry. We don't do hardware repairs here.

My laptop doesn't show anything but the mouse after the logon page at windows 8.1

my laptop doesn't show anything but the mouse after the logon page at windows 8.1..Acer E5 473G 57QQ

Hi there! When I read your post, I realized that a clean boot or a safe mode might help. I suggest you read the articles on them if you are not familiar. However, a legacy boot menu to enter a safe mode is unfortunately difficult in windows 8.1 as revealed in method 5 of the following article http://www.7tutorials.com/5-ways-boot-safe-mode-windows-8-windows-81 I am sorry that I was unable to provide a solution directly but hope that this reply will give a direction..............

Itunes doesn't sync Anything but it recognizes my iphone 4

itunes doesn't sync anything. but it recognizes my iphone!
And also uninstalled and installed itunes. still the same. itunes finds the devices, starts with the backup and stops always at step 5 (out of 7). It doesn't sync anything, no music, no apps..
it always stops after:"..to determine apps for synchronisation"

There is no option like "sync all photos"
There is option for "All folders".
Am i correct?
