HP Display :: Pavilion G6 Screen Backlight Flickers
Jan 19, 2015
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.
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?
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.
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?

Currently whenever I startup my laptop the display flickers. If windows fully boots or I try to enter one of the startup menus the will flash briefly on the screen and then the display will return to and remain black.
I am able to run an HDMI cable to my TV and it seems to be running fine other than going black with the occasional distorted picture of windows booting.

I am having a problem with my Pavilion dv6200
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.

The screen flickers abruptly. And the screen gets garbled as well. But it seems to have really been knocked out today. The temperatures were looking fine at 60C but on a reboot the screen has like six small screen showing up instead of one with the HP logo.
Is my GPU dead? If so what are my options now?

Model: HP15-N096EA ... When the laptop is turned on the screen colurs are inverted i.e. blue becomes orange, white becomes black etc. at times it flickers back to normal colours i.e blue shows as blue etc.
I have checked magnifers invert colours isn't turned on but when I do turn it on the inverted colours switch to normal colours obviously. There is also a vertical shimmer like every other vertical line is missing or phases in and out.
I have booted into safe mode to see if its a driver issue but the colours are still inverted, I've booted into the BIOS and again the colours are inverted and just to cover all bases I booted a live DVD of Mint Linux 17.1 and the legendary green of the mint distro was a lovely lilac. I've also tried high contrast i.e. Left ALt + left Shift + Print Screen.
My feeling is its the graphic chip or the monitor and I'm hedging more towards the monitor. Tomorrow I'll do a screengrab to see how that comes out and will also connect to an external monitor to see if the flicker and shimmer is still present.
Considering this is literally a month and 6 days out of guarantee it pretty bad, I would have expected a bit longer from a laptop before it started failing.
Update from Yesterday: I did a screengrab from the HP using the snipping tool in windows 7, this showed the colours inverted i.e. negative, I saved that screengrab to a USB stick and opened it up on my Mac, the image showed correctly i.e. not as a negative.
This is the image that is displayed on the laptop, there is no colour inversion, none of the graphics settings appear incorrectly set, I did actually set all settings back to defaults.
This is the screengrab from the laptop as it displays from another computer, which, in my case was my Mac. The screen appears to be displaying correctly, hence the screengrab image below but for some reason it is displaying an inverted image - Its like there is an overlay on the screen.
Could the inverter be faulty?

I purchased my laptop about two years ago. A few days ago, the screen suddenly dies, and on boot, it flickers a few times with the proper display, but then goes blank. The backlight seems to remain on though. When I use an external monitor with the HDMI port, the external monitor works fine, however the laptop screen remains blank. Here's a video of what it looks like when I first boot the laptop: [URL] .....

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 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...............

for some reason the on screen display meter for my volume when pressing on the keyboard suddenly disappeared, I would like to get this back. I found this thread in the forum URL.... which another was having the same problem I'm having. The only difference is that I'm using HP Pavilion G7 with Windows 7.

This problem has bothered me since I have installed the windows7 rtm.
i am using integrated graphi card, everytime when the machine wakes up from sleep, and if the external power is unpluged, the screen starts to flicker, and windows 7 reports "displayer driver stopped working and have been recovered", looks like a driver problem, but i have downloaded from the driver from sony website and intel website, none of them solves this problem.

I have a Dell Studio 1745 and there is an issue with the magnetic switch. The issue seems to be that the switch itself can't seem to make its mind up whether it has been activated or not. On boot the screen flickers on and off slowly, placing a magnet near the track pad (where the switch is located) increases the rate of the flickering, however it does not solve the problem. Looking inside the laptop the switch seems to be a soldered chip, is there any way to solve this completely? I've connected it to an external monitor, however the picture will only stay on the screen with the magnet in place, removing the magnet causes the picture to come away from the monitor and back to flickering on the laptop.

when I turn on my Z, the screen glitches two or three times upon hitting the login screen. Does this happen for anyone else?
Sometimes, (it's happened once or twice) my graphics card even failed upon logging in and had to be reloaded, and even, on one occassion, completely shut down my computer (Straight to black, green light turned red) in the middle of casual browsing.
Are these causes for concern? Should I return my laptop?

Issue #1
Specifically 15" Late-2008 models (first of the Unibody range) running on the integrated 9400M graphics mode; where the the top 1/3 of the screen blacks out for a few millisecond ever so randomly with no obvious way of reproducing it. Sometimes the whole screen blanks out instead of the top 1/3 part.
Video samples of those that are lucky enough to capture it on film.
I've performed multiple SMC/PRAM resets, fresh system installations with full updates (10.5.8) and they don't seem to go away.
_________________________
Issue #2
Weird graphic glitches on the same machine, best described with the following video and text:
Several observations to reproduce the glitch:
- Happens only on battery mode, regardless of which graphics card (9400M or 9600M GT)
- Happens on a freshly-installed, fully updated, SMC-resetted system with 10.5.8
- Only happens when you scroll very quickly (i.e. using the two-finger scroll on the touchpad) on a long list (refer to next point)
- Drop down list/menu has to be extensively long that requires at least two or three screen's worth of real estate. An example would be the 'Fonts' folder (/Library/Fonts), drop this into the dock as a stack and view it as a list.
- Reported to happen occasionally with the Spotlight search menu.

My work computer will flicker, go blank/black and sometimes I can tap on the battery or the hard drive and it will come back. Sometimes (more times than not) it will require a total reboot. Lately it won't even load. It will load the Dell screen then it says Starting Windows the logo comes on then it goes black. It still loads and everything but I can't see anything. I've replaced the hard drive so I know it's not that. I've loaded the computer in safe mode and I have NO problems with it when it's in safe mode, only when it boots normal. I tried the FN+Power but nothing happened when I tried that the numberlock LED is the only one that stays lit, the others didn't start flashing or anything

I just got a thinkpad yoga and I have noticed since I started using it that the screen randomly flickers. I can't narrow it down to a time where I'm doing a specific task.

I was using my HP Pavilion g7 the other day, while gaming and the screen went black for no appairent reason. i haven't down loaded anything recently and i run virus software.
We went to the HP support web site and went through several diagnotics. When the laptop is rebooted the screen on the laptop will flash images of my desk top but once the machine boots up the screen remains blank. you can see the glow from around the edges but that is it. I have another monitor plugged in currently and the system is functioning propertly except for this. We have also done the following, hard reset,Test for memory modual problems, test the hard drive. I was also trying to update the video drivers but the system tells me the drivers are working properly.

I have an hp pavilion dv6. It was purchased at the end of 2010. My computer teens to get hot a little quicker than normal. It had overheated a couple times, but not recently.I recently went on a road trip and when I got back my computer screen won't turn on. While I was away, I took the bottom plastic screen off and put it back on (one of the sides had come loose and a tab was sticking out). I also tightened all the screws on the main cover on the bottom because some had come loose.When I got home and tried to turn my laptop on, the screen wouldn't turn on. I can hear the fan turn on. The light indicating the wifi was on, but showing that it was off- and it was on when I last used my computer. Also, the capslock light is blinking. I don't hear any sound from the speakers or anything like that. I tried hooking it up to a projector but never got a signal. I tried unplugging it and removing the battery and holding the power button for 30 seconds but nothing changed when I tried turning it back on.

I've checked my control panel settings and then the advanced settings (for notification icons--which doesn't apply to this problem).
What ever I set, I'm working at my computer and screen always goes to sleep 1 minute after if I don't touch the keyboard.
What am I not getting. I need at least 5 minutes or so before it should go to sleep. My computer at the office only goes to sleep after I make it.

I have had my Hp dv7 notebook for a few months now and have had no problems. But all of a sudden, I turn on the computer and see nothng but a blank, black screen. I do not know if I changed the display settings or what, but I cannot see anything. I know the computer is functioning because the fan turns on and the keyboard lights work. When I connected my laptop to an external monitor, I was able to see that my computer was on and fully functional. In fact, I am using it right now on an external monitor to type this message.

I recently purchased an HP Pavillion X2 2in1 laptop and want to connect it to my TV. The laptop was recentluy upgraded to windows 8.1. When I connect using an HDMI cable, the TV recognises that the HDMI is connected, but the laptop screen will not transmit onto the tv screen. When I hit f4 to toggle the display, it says 'Your PC cannot project to another screen. Try reinstalling the driver or using another video card.'
When I go into control panel as recommended on other queries, the adjust resolution screen does not give me any other options than the Basic PnP display. It's like my laptop cannot detect my tv. It is not in my computer, devices or anything. I didn't attempt connecting it to my tv when it just had windows 8 on it ...

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?
