HP/Compaq :: Backlight Very Unstable After Display Replacement
Feb 19, 2010
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?

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.

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 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?

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?

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.

new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...

XPS 16, approximately 2 1/2 weeks old, using a 5100 wireless card.
I'm having ALOT of drop-off issues from my wireless network when my system is unplugged. Sounds really odd, and my system is either set to balanced or high performance when unplugged, but there it is.
When plugged in, I have yet to notice a dropoff. So I'm assuming they are connected.
It'll typically drop for about 2-5 minutes and then reconnect.

My LAN port seems to be unstable. I insert the cable and hear the clicking sound but no LED turns on. I have to push the cable further to get the indicator on. It may also disconnect if the cable moves.
Â
Is this a faulty port? And, if so, what does it take to fix it? (i.e. what do they replace/fix?)

For a while now the wireless connection on my laptop has been very unstable. I had used it for about six months without experiencing problems, but a month or two ago I started getting very frustated with it.Â
Â
The wireless can be turned on just fine and has no trouble finding available networks. No problem here. But when I try to connect to one it rarely works, and the few times were it does connect, the internet is incredibly slow. I would say it works flawlessly and fast about 10% of the time. The rest of the time it's like I just explained; it either won't connect or is too slow.Â
Â
I don't know what suddenly caused this, since it worked perfectly when I bought it. Updating the wireless card drivers didn't work.

I have a problem with an hp zv6000 (no backlight). When I giggle the lid switch it will flash and sometimes stay on for a short (less than a minute) and then go back off. Inverter or just a bad switch,

I have a dv9700 that I have owned for over a year and recently upgraded to Windows 7 (about a month ago.) I was happy with how everything was working until suddenly today when I went to turn on my laptop it appeared the screen was dead...upon looking closer I realized that the backlight was off. I could barely make out anything on the screen but it did have an error message stating that Windows failed to boot and gave the option of repairing the system. I went through this "startup repair" utility (still no working backlight) and got my computer to boot up. Everything seems to run normally now except the backlight is still not functioning most of the time (at the moment I have the screen balanced just right so that it is on.) I had a similar problem with my screen about half a year ago but the laptop was still under warranty at the time so HP replaced the screen for free...not the case this time unfortunately I seem to remember reading that flashing the BIOS can solve a problem like this, however there is apparently no support for Windows 7 through HP Support's software and drivers page (I tried installing the latest version of winflash for my laptop...vista 64 bit but got an error message saying it was not compatible with my system)

I've just reinstalled win7 Ultimate on my 7720 (09/2012) and have 2 problems: My BT mouse (Dicota BlueLight) stops working after a few minutes, and I have to remove it, and re-pair it several times before it will actually work. Each time I pair it I'm told it's working fine, and the driver is correct, but nothing happens. Ocassionally it will actually work, but only for 3-4 minutes before simply stopping again. The Bluetooth radio is showing as Generic Bluetooth Adapter in Device Manager.Also, in Device Manager I have  a USB controller showing no Driver (Location: PCI bus 0, device 20, function 0) and I cannot find an appropriate solution anywhere.

HP pavilion 15.6 inch screen laptop (15-e084ca), AMD Quad Core A10-5750M and 8650 Radeon graphics, 1TB hard drive, 8 MB DDR3 SDRAM, Windows 64-bit 8.1.
Â
I have a Monster bluetooth HD Clarity micro speaker, a Philips bluetooth shoqbox and a Philips bluetooth sound shooter.
Â
In all 3 cases, I have been able to connect the speakers and use them but the connections are unstable. The laptop automatically breaks the connection. It's happened several times. I have many different versions of this problem.
Â
Once the speaker is disconnected ( either I manually disonnect it myself or the laptop does it on its own) it can be extremely difficult to establish a reconnection.

I am having some strange problems with the backlight on my dv9700...I started a thread about this maybe 2 months ago but the backlight for whatever reason started working again and I didn't have too many issues with it until recently. Lately the backlight has only been working when it is plugged in...If I unplug it but leave the lid open it still works but as soon as I close the lid and open it again its out until I plug it back in and open and close the lid. Now I can't get the backlight to work at all except it lights up for 2 seconds or so upon closing and opening the lid. I removed the display bezel to access the display inverter and check for any loose or damaged connectors but they all appear to be fine...unplugging and plugging the display panel cable connector back in also causes the backlight to work for 2 seconds and then go out again. Besides the backlight issue the laptop seems to be working perfectly fine...can anyone help me figure this out? I should mention that I upgraded this laptop to Windows 7 right away when it was released.

In own a Pavillion DV7 2070ED. I spilled wine over the keyboard...
My insurance will cover this so money isn't really the problem. So I was thinking about buying a backlight keyboard instead of the original black one (which works really annoying in lowlight conditions).
Now I found a thread about backlight keyboard but I'm unable to find out which backlight keyboard is compatible with my laptop. On the motherboard there is input for the keyboard-backlight. So thats not the problem.

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.

I just got a 8730w (non-dreamcolor) and experience serious backlight bleeding. It's kind of irritating because it's obvious. Brightness set at around half only.
Does HP warranty cover this?

I have a DV9000 and just yesterday it started where the screen will go black but I can see what is going on on the screen but it is extremely faint. When I close the lid for a few seconds and open it back up it the screen appears like normal but only for about twenty seconds and then returns to the black. If I hook it up to an external monitor and I can see what is going on.

Recently bought a Acer Aspire Nitro v15 with windows 8.1 with a qualcomm atheros ar5bwb222 wireless network card. The connection is really unstable and often disconnects and have very few bars. This is not from the router since the connection on my phone and other computers are fine. The connection (when i have it) is also really slow compared to when i use my phone on the same network. I tried updating the drivers but it says my latest drivers are installed. Could this be a Windows 8.1 problem? this is my first time owning a windows 8.1 computer.

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.

I recently took my Compaq Presario C714NR laptop on a road trip, and one day some water spilled on the case without me realizing it, so that the case and laptop were wet when I got to my hotel room. The screen no longer illuminates - I can just barely see the proper windows and images on the screen if there is bright light in the room, but it's nearly invisible. I assume that either the backlight is dead or that a wire/connection to the backlight is loose or shorted.
Several months ago I had to replace the screen when the laptop was dropped and the screen broken (bought a new replace ment screen through eBay, replaced it myself), so the screen has had a bit of a hard life.

my backlight and touchpad are not working since i replaced my DV3000's motherboard with one meant for a DV3500 (wrongly listed as DV3000). I think that it has something to do with the lid sensor.

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.

How to remove the screen from the base of the notebook, and how to test cable, or LCD screen itself? Is replacing the LCD screen the correct option?
