Sony :: Vaio Display- It A Backlight, Inverter Or Screen
Dec 7, 2009
i have a sony vaio c2z - nvidia geforce 7400; x-black lcd
i have had a lot of problems with my display since august. although i didn't notice at the time, it happened soon after i installed the Win 7 RC.
when i start the laptop up the screen looks all distorted and the colours arent correct:

but when i take screencaps and connect it to another monitor everything looks fine.

i assumed the screen was knackered, but i installed a game a few weeks ago and it brought the display back to life, only for it to look crap again when i restarted. this also happened when i did a clean install of vista, only for the display to go bad when the updates installed.
i have tried many times, but have been unable to replicate this...............
I have a laptop which has a dim screen, I am not sure if its the inverter or the back light that needs to be replaced. Its a Sony FS-740/w series laptop. I want to be sure which one needs to be replaced so that i can order it online. way to check if the inverter is working correctly.
Alright Well I bought a new inverter plugged it in and it still is doing the same thing. Only when i jiggle the wires the light goes on and i see the screen but not for long. I check for loose conncections but can't find any. The external display is fine. I'm wondering if it could be the actual bulb.
After using my new Vaio Z for a few hours i noticed a slightly greenish hue at the bottom of the screen(1600x900). It's mostly visible with white or very light background.
There are a few of those spots and i think it originates from uneven LED backlight. It's not instantly obvious, but after i've noticed it I find it somewhat distracting.
I have a DV9000 and the LCD suddenly went dim. I thought the inverter had gone so bought and fitted one. However now when the laptop turns on for the first time I can see the display for maybe 1-5 seconds (5 on initial start, less on soft restarts), but then it goes dim again.
I have tried unplugging AC/Batt and holding power for 20 seconds but it made no difference.
my HP ze4230 laptop Trying to reboot it with a new harddrive it went black on me with no warning.I put the old harddrive back in.Its still dark but I can see in the screen very faintly with a flashlight.I hooked it up to my desktop monitor and it worked well.My problem is,I took the inverter out but how can I tell if its bad or if its the backlight that is bad..
I have a dell inspiron 600m laptop and my screen is dimmed out. If I turn of my laptop and restart it, the display will come on for a second ( but it is a little bit reddish) and then I hear a noise and it light goes off, and I can;t see anymore. However, I am sure the computer is still running properly
I am sure that the computer is on, and is functioning properly for two reasons:
1- if it is sunny, i can see my desktop, and what ever I have open, be that a browser, a word document, so on and so forth
2-when i connect my laptop to an external display everything is fine...
I've read the sticky and many threads here but I'm confused. What is the symptons of the backlight/inverter problems?
My DV2000, when power off the monitor is dark, when power on, the monitor lit/iluminated. But nothing on the screen. The harddrive led blinks so it's accessing.
I thought it was inverter so I replaced it with the $8+ from y'allstore. It didn't work.
I accidentally dropped my Compaq Presario C571NR and it fires up Ok, but the screen is black. I have tested the video card with other monitor and it seems to work fine. I did some research and I found that it could be that either the inverter board or the backlight might have gotten damaged. I have purched a new inverter card online (awaiting arrival) to replace the existing one, but I wanted to know if any of you know which of them has the propensity to get damaged first, the inverter or the backlight?
I'm hoping is the inverter because it seems the easiest to replace, but if it's the backlight, then I'm screwed because I've read it's quite difficult to replace and it's more expensive. Compaq says they'll charge me $300 to fix it (since my warranty has already expired) but I might as well get a new one if the new inverter doesn't fix the problem.
my laptop screen backlight goes off, when I rest my hand on the left side of the touchpad. The darkening of the screen can be also reproduced when a small pressure is applied on the case just above the ethernet port or above the headphones port. When the screen goes dark, I can see that everything is running normal, if I shine on it with a lamp or strong light. The resulting effect seems to be the same as if I would have lowered the brightness to minimum. Â When I don't press the area described above, the screen is just fine. I am sure this problem is not software or OS related. I googled it a lot and my guess is lose connection on the inverter? Â One last thing - idk if related - sometimes, when I boot up the laptop, the backlight is turned off and I have to adjust it by pressing F3.
My current problem is that when switching from the mobile power-saving GPU I lose the backlight on my screen when the high performance GPU kicks in. The HDMI output is displaying video when in High Performance, but the screen of the laptop will only show a picture with no backlight, and can only be seen by shining a light on the screen.Â
Just started happening the last few days, I've tried a system restore (didn't allow it), tried uninstalling all of the AMD drivers and software then reinstalling with their updated drivers, as well as the same process but with the HP drivers that came with the laptop, still the same result.Is it possible for the high performance GPU to be failing some how or is this a software issue?
I am having a problem with my Pavilion dv6200 Â This is third time the same thing is happening to me. After i install some updates, display dimms, and background light became darker. When i restart computer, and enter BIOS, or if i am just looking at the screen before i log on to windows, backlight is normal.
Whats the major difference between 16.4" VAIO Display (1600x900) and 16.4" VAIO extra-wide HD display (1920x1080). Upto what angle I could see my display in VAIO Display (1600x900)? Can I watch HD movies perfectly in VAIO Display (1600x900) ?
When I try to use the brightness level in between LOW and HIGH, my LCD backlight would go off, and the screen would be dark and almost not visible at all. There are also vertical bars at random spots, stretching from the top of the screen to the bottom of the screen. I can only use it with either LOW setting or HIGH setting, nothing in between.
This problem just started on its own. I have not installed anything such as drivers or programs. No updates(was updated after the problem occured to try to fix it).
I love this laptop to death and has been the best laptop in the past 15 years. I would hate to see it go so I need this fixed.
I will update later with pictures when it gets dark here b/c the pictures now are not showing up with the bars.
I purchased a lid, bezel, and cable, too. But the cable has a blue connector that looks like it would connect to the inverter. Is there actually an inverter board that goes just below the led lcd screen? If so, does anyone know the part number?
My screen went black. Did some research and found it it was most likely the inverter.
I replaced the inverter but it still flickers and then goes black while its booting up.
How can I tell if this is the back light or if this is the lcd itself? I've heard the backlight is hard to replace and I might have to take it somewhere to have it done which would cost $$ .....
how many different types of screen inverter there are for the dell latitude d520(15") as ive tried 2 different ones without success and i know the only fault is the inverter.
i just replaced the previously matte chi mei display on my hp compaq 8510p gb967ea (WSXGA+), with a brand new lg-philips glossy one (both certified for my notebook, of course) and for the first time ever on that notebook (ie. first time since its acquisition summer 2008) i experience backlight issues now.
just like on my very old nx9030 (which happened twice while under warranty, so its been repaired for free, and then once after the warranty period), the backlight keeps turning off by itself or when touching the lid or typing a bit heavier. so i have to close the lid and open it again to make it turn on again!
i watched out for all the cables within the frame and the one going into the inverter board, so none should be squeezed or so.
shall i open it again and look for a specific cable, jack or something like that, whether something is being squeezed?
I have a Dell XPS13 purchased a couple of months ago, this morning the when I started the latop the display is not working. I can see the backlight comming up when I boot it but nothing else.
The external display works and all other components seem to function properly.
I am pretty positive that my laptop does have a backlight. However, I didn't need it at the time and I shut it off. But now I can't turn it on. I originally remembered adjusting it through the power options and that there was a little slider to adjust the brightness of either the screen or the keyboard. I could have been wrong though, since I no longer see the second slider for the keyboard brightness. I have tried everything I could find to get the light to turn on. I used the mobility center but there is no keyboard option. I have tried the fn + spaacebar, fn +f5, and my keyboard does not have a specialized key to adjust the keyboard backlight either. How to turn on the backlight?
I've problems starting my Vaio SZ2. They occured one day without changing anything (Hardware or Software) before.
If i push the power button, the screen backlight turns on but remains grey/black. No vaio logo, no boot screen, no bios access! I unscrewed the whole computer (3 years old) and checked all the cables. Then i released the screen cable from the graphic chip and tried booting with an external display! And that worked!
It seems to be a problem of the display/display cable or the graphic card.
I just bought a second-hand Sony Vaio TZ 390, which came with Vista. I updated to Windows 7 and installed all the drivers. Everything seems to work but I cannot get the Vaio TZ to output to the external display. What happens is the external lcd gets a signal initially when I turn on the Vaio TZ (connected to the lcd) but it loses the signal shortly after I log into Windows 7. Btw, the lcd I use is a Samsung 2333HD.
I have a VGN-AR550U laptop. According to the property page for the Display adapter it is: NVIDIA GeForce 8400M GT. I want to be able to run a Powerpoint presentation where the slides are being shown on a big screen and the notes are shown on the laptop screen. I understand this has to be done thru a dual monitor type of setup. Can I test this without actually hooking up the big screen or does it automatically go into a dual monitor mode when you plug in the second monitory. When I select presenter view it says I don't have a second monitor.
