I have an issue with the LCD, 1/5th (right side) of the screen is completely white
I had overheating problem with Toshiba Satellite P35 laptop and your guide helped fix it.
I have another issue with the LCD screen, 1/5th (right side) of the screen is completely white (off white) and it is only garbled at times, mostly though it stays solid white, both at BIOS and OS. If I hook up external Monitor, it looks fine (no white). I guess that means bad LCD screen? Do you have any suggestions on what to try before I shell out money for a new LCD if it’s even available?Needless to say your site is fantastic, a true community service. Thank you.
Many thanks in advance for all your guides.
If the external monitor shows normal video, then apparently the problem is somewhere inside the display assembly. I would say that the problem is the screen itself, although there is a possibility of a bad video cable. You can try this. Grasp the top left and right corners of the screen with your left and right hands. Twist the screen into opposite directions (left corner goes toward you, right corner goes away from you and then backwards) to apply some tension on the screen. Do not twist too much or you can crack the screen. Do you see any changes in the video output, does the line disappears or it changes somehow? If the video on the right side is changing somehow, them most likely the screen is bad itself.
I would also try to reseat the video cable on the back of the LCD screen. It’s not very likely that reseating the cable will fix the problem, but I would try it first anyway before you spend any money. I’m positive that a new screen for your laptop is available, but it’s way too expensive. You can check for the screen part number when you reseating the video cable. It would be somewhere on the back of the screen and looks like: K0000023240 (you might have a different number). After that you can search on the internet by the part number.

I have a TFT laptop display (Aspire 9500) that is displaying a white screen. It is getting color data ok from the laptop, which I can see by tilting the screen vertically, but it seems to be incapable of displaying black or sustaining an image when viewed straight-on. When the display is first attached, it is clear for a moment (although black is still washed out) and then fades into all white, readable only at an extreme angle. Changing the LCD brightness at that point causes the whole screen to become lighter or darker degrees of white. Have you ever encountered this issue before? Do you have any idea what could be causing it?

I have a Sony Vaio VGN-T140P laptop, one of these tiny 3lb ultralights. It has a crack in the screen so there is a black blob in the corner of the LCD, other than that the LCD looks normal. However, Sometimes when I boot it up, the screen is just black but I can hear the HDD turning and the laptop is humming but there is no display. When it does this, which is intermittent, it wont display even with a regular monitor plugged in. Now lately, I boot it up, windows startup screen comes up, it goes all the way to the desktop and it shuts itself off, power and all. I booted into safe mode and that went fine, then in safemode I tried to click on the display under the control panel and it did the same thing, shut itself off. Could this be related to the failing LCD or is the motherboard bad? Any ideas?

Yvette Piraino,
If the laptop will not display even on the external monitor then I would assume something is wrong with the motherboard, not the LCD screen. Usually when you have a faulty LCD screen, you still should be able to use the notebook with an external screen.
Try removing the hard drive and test the notebook again. In some cases bad hard drive can halt the entire system. Test the hard drive, you can use Hitachi’s drive fitness test.

OK, I have a similar yet different issue. I have an Acer TravelMate 4670. The issue is that I have a 2.5″ black strip on the right side of my display. It doesn’t appear to be a screen issue, as my entire desktop is visible; it just appears smaller and offset to the left. Additionally, there is a 1/2 inch strip under the taskbar at the bottom of the screen that I can’t collapse. When I scroll the cursor to this “no man’s land” the cursor’s arrow disappears and is replaced by a black vertical line. The issue occurred a couple of times before but self-resolved on reboot, but now seems to be permanent. I have tried to adjust the screen aspect as well as the display settings, but nothing changes the display back to a full screen view. Any thoughts?

If I remove the hard drive will the computer still turn on? What do you mean by remove the hdd and test it again. What will come up on the screen if there is no hdd. Sorry, I’m not a tech so I am ignorant to all this! Thanks for your help! yvette

Carl,
maybe the video driver is corrupted? Try booting the laptop into safe mode (it loads basic VGA driver). Do you still having the same problem in safe mode?

Yvette Piraino,
I know that in some cases a bad hard drive can halt the entire system. You mentioned that sometimes you have no video on the laptop LCD or external monitor and I’ve seen some laptops with a similar problem and it was caused by faulty hard drive. As soon as you remove the hard drive, the laptop boots with video and you can see the company logo (Toshiba, Sony, Dell, etc…) on the screen.
I’m not really sure what’s going on with your laptop and just trying to come up with some troubleshooting ideas.

Thanks for both suggestions. When I put the computer in safe mode, the screen is still compressed to the left, leaving a 2″ black strip on the right side of the screen. Again, there aren’t any true “dead spots” on the LCD….the entire desktop is visible and functional, I can access all functions, run graphics and videos etc., but the desktop is compressed to the left and this strange “mirror” of the task bar appears under the task bar. I removed and reinstalled the hard drive, checked the video driver, changed aspect ratio, changed display settings, run virus checks, spyware checks….now I’m stumped.

Hello, i seem to have a Problem like that, But mine seems to be Different.
I have an HP Pavilion Dv1000 Entertainment Notebook. Got it for free, From my Sister. and whenever I Turned it on, the Display shows about a 1″ white strip at the bottom, like a wire in the Display cable is Damaged. But whenever i tilt the screen up, it goes away, but leaves white scan lines. sometimes, if I am lucky, it goes away altogether. The LCD, from what i see, has no problems to it what so ever, its just the Cable going to the LCD. Any suggestions?

Carl,
Maybe you should try reflashing the BIOS?
February 7th, 2007 at 11:45 pm
Jeff,
I think in your case it’s a bad LCD screen.

Hi, I have a LCD problem with my sony vaio pcg-k45 laptop. When i power it on i only get a white screen.
I’ve been reading some of the previous answered questions on similar situations. I know that the laptop works because when i hook up an external monitor to the laptop i can see everything. First i thought that it could be the screen inverter, lcd harness cable or the lcd. i was able to get a good deal on all three parts on ebay so first i tried the screen inverter and the same problem resulted, then i tried the lcd and same problem, finally i changed the harness and still the same problem. After reading some of the comments i checked the harness’s pins to see if they were damaged or bent but they look fine. The backlight works on both LCDs.
Could it be the video card and is it replaceable? and can you please tell me what a FL inverter is and could that be the problem? Thanks.

Frank,
If the backlight works fine, it’s not a screen inverter (LF inverter) problem. You’ve replaced everything inside the display assembly but the laptop still experiencing the same problem so there must be something wrong with the video card. Sorry, I don’t work with Sony laptops and don’t know if this model has a video card integrated into the system board (not replaceable) or the video card is a discrete module.

Thanks for your service! I have a Toshiba Satelite 1805 S254. When I am using the computer the screen will go off. (I can see very faintly what is on the screen). If I push F5 key it comes back on. It may stay on for a 5 secs. or 5 mins. but it shuts off again. I went into the power saving settings and adjusted to “NEVER SHUT MONITOR OFF”. This did nothing. A day later I could be using it and not have a single problem. At home I can hook it up to the TV but I can’t take it to work with me when it is having this problem. Any ideas? Thanks so much!!

Joe,
It could be a problem with the screen inverter – the board that provides power for the backlight lamp. The inverter board is located inside the display assembly below the LCD screen.

Hi there,
I have a Toshiba TE2100 that I formatted in order to clean up the hard disk and I reinstalled windows xp home edition. That was all good until I downloaded service pack 2. Thereafter, the start up screen is all good until it gets to the desktop screen which then does not stretch to cover the entire screen. The right side of the display has a black vertical strip about 1 inch thick but everything else (toolbar, taskbar etc) seem to be in the right place and in proportion, only shifted over to the left so that what’s displayed is not covering the entire lcd screen (1 inch missing from right hand side).
Any help would be much appreciated, everything is usable but it bugs that my laptop screen is not fully used.
Thanks,
Dan

I do have a similar problem. I have a Toshiba Satellite a70 with a 16:9 lcd screen.
Last night, when I came home with my laptop in his shouldercase, i accidentally dropped it a bit to hard. the case hit the ground from a height of about 1 foot. (which in my opinion shouldn’t be to bad considering the protective stuffing inside) Today, when I plugged my laptop, me screen is having this issue: there is a 1/5 right part of the screen not active, with a small 1/2inch zone (on the left of the 1/5 right zone)mirroring the last pixels shown, and same on the bottom 32 pixels of the screen in the active left 4/5 section.
In the display property, it no longer display the resolution of 1280×800, but shows 1280×768. also, my desktop is bigger than the shown screen, as i can scroll left and right to see the missing part. if i set to 800×600, i get no auto-strech, and at 1024×768, i can’t scroll my desktop anymore, but all is shown in the 4/5 upper left part of the screen(ie the 1024×768 first top left section of the screen)
I giggled with the screen connector, and there is no difference. I also flexed the screen top corners to no results. the problem appears at boot, (from Bios to windows). It’s as if my laptop didn’t recognise his 16:9 wide-screen anymore, and used only 1024×768 instead.
I tried removing my ram expantion, no difference. and playing a game running at 1280×800. The game crashed on startup.
Any clues?
Ram? LCD? HELP!

here is a screen shot that better explains it:

I own a hp pavilion dv1520us: the LCD screen has been progressively going cloudy on the right side of the monitor. Of course this started to occur after the warranty and it started small and now it’s almost halfway across the screen. I’ve taken very good care of my laptop and I can’t seem to find the issue. Any suggestions???
…Thanks

@Carl
Came across this post and you described the problem I am having perfectly (display compressed to left and mirroring of taskbar at bottom) was wondering if you ever found a good solution.

I have an acer aspire and on the right hand of the screen there is a 3in strip that is white and I cannot get rid of it. If anyone could offer some help it would be greatly appreciated.
