Flickering screen question

• Laptop 17 HP envy flickering screen? (in fact some troubleshooting)

  It flashes when I click on an item or open a folder. Also, he goes crazy when I put on a video.

  Things I've done:

  Updated drivers.

  "Hold down the power button / stop" method.

  I have clues:

  1. I remember when I received the laptop, he would always sparkle in exactly the same way when a charger that has been plugged in was too weak (can leave message too low) and change the charger always fixed.

  Now I still have the same charger (I have 3 hp and 1 dell Chargers at home that match my laptop) and none of them seem to be "pretty" (x 2 65w 1 x 60w and 120w x 1).

  (2. another funny is that when I uninstalled my drivers Ati Radeon HD5850 completely, there is no flickering, but obviously, I need to have what I use this laptop strictly for the games)

  3. the screen refresh rate is 60 Hz and not possible to change.

  4. There is NO flickering on an external display (tried two televisions, both have a little clicker)

  5. you say that it's a hardware problem, but I actually somehow got to operate the flicker-free earlier this evening and are stayed all night play and it did not cause me any questions. It was working fine.

  6. sometimes the PC freezes (could this be a battery problem? because I currently does not use one as mine are broken and I'm waiting for a new ship)

  7. I recently had 2 blue screens of death. A when installing the ATI drivers and another that I don't remember.

  Sorry for the wall of text, I tried to make it easy to read

  Hi wallyson691,

  Welcome to the HP Forums!

  I would like to take a moment and thank you for using the forum, it's a great place to find answers. You have the best experience in the HP forum, I would like to draw your attention to the Guide of the Forums HP first time here? Learn how to publish and more.

  No need to apologize for the amount of text.  It is always better to have too much information then is not enough.

  It is very useful during validation to include your exact model of HP laptop and the operating system you are using.  How can I find my model number or product number?

  I noticed that you have a flickering screen problem and you have successfully updated the drivers but it has not fixed the problem.

  When you have uninstalled the Ati Radeon HD5850 the problem disappeared.

  You had this problem before, and it was linked to the power.  You have tried different adapters but no change.

  Have you tried a different outlet?

  You did all your Windows updates?

  Have you tried HP Support Assistant to help with updates and issues running?

  Did you run MS fix to try to solve the problem?

  Here is a link to the display quality problemsthat can help.

  If you think it may be a conflict in the origin of the problem, you can try using Microsoft System Configuration (Windows 7) to find out what is the cause.

  I would like to start a test of material just to rule out this possibility.  Test of hardware failures (Windows 7, Vista)

  You could try a restore to where he worked, using Microsoft System Restore (Windows 7)

  You can try to install the original driver to see if it helps. Using the Recovery Manager to restore the software and drivers (Windows 7)

  You can consider to recover to factory.

  Performing a recovery of system HP (Windows 7)

  During the recovery process, you will receive a prompt to back up personal files to avoid loss.

  Restore files that have been supported to the top using HP Recovery Manager (Windows 7)

  I hope this helps.

• Smart touch 610-1010UK Office: flickering screen on Touchsmart 610

  During the evening of 11/11/15 the flickering screen started. The mouse moves the cursor, but nothing does. F1, F8, F10, and F11 repeatedly pressed when starting up do not appear all the screens.  I see others have screen similar flicker. Help would be appreciated.

  Resolved - on the Microsoft Forum, we thought that Windows Update KB3097877 on Windows 7 might have caused the flickering on the PC.  Windows have now pushed another version of KB3097877 for this problem.   The good news for those whose parts are automatic update of Windows is that all you have to do is turn on your computer and put up with the annoying flicker until the new update gives you the logon screen.

  If any good came of this, is that we should remember to save regularly.

• Tecra M5: External monitor flickers - grounded question?

  Hello

  I just bought a new Acer Full HD LCD Monitor (P244W) and have tried to connect on my Tecra M5 VGA port.
  It works, but there is a noticeable and more annoying flicker. I tried with XP (SP3) and now Vista (SP1) and it happens for both. I have the latest BIOS and NVidia drivers. The actual laptop LCD screen still works fine, it's just the external screen that flickers.

  To make sure that there is nothing wrong with the monitor, I plugged the ATI video card VGA port on my desktop pc and it displays fine without flickering.

  After completing the web for people with similar problems, I narrowed down it to her being caused by my power adapter with a grounding problem as the flicker disappears as soon as I unplug the AC adapter and just run the battery. It seems the solutons common to this problem are:

  (1) try some different VGA cables with better shielding against interference.
  I tried this and it made no difference. I tried cables with or without the magnet ferrite/Starter thing at both ends of the cable and the flicker remained.

  (2) try the different screen resolutions and refresh rate.
  Tried to adjust some lower resolutions, but the twinkle remained (not to mention that I prefer to keep the native resolution of 1920 x 1080 for my monitor). The NVidia driver allows only 60 Hz refresh rate at 1920 x 1080, so I couldn't change that.

  (3) make sure that the computer laptop AC adapter / CC and the monitor are connected to the same wall jack and are on the same power expansion card.
  Tried, but it does not solve.

  (4) run an extension cord to another circuit of power supply in my house and to the AC adapter and the monitor of this to see if its something wrong with the wall socket using im.
  I tried connecting to a wall in my laundry, but does not resolve it.

  (5) try using a different power expansion card and nothing else is connected on the power adapter and the monitor.
  Tried, but it does not solve.

  (6) get a pin 3 to 2-prong adapter, so the power adapter is connected to the Earth is no longer.
  Most of the people on the web seem to say this corrects the problem, but I don't know how it is safe to leave this way long term. Especially, when stories of mobile phones capture the fire are multiplying.

  (7) get an adapter to generic brand as they sometimes solve the problem better than the Toshiba power adapter grounding.
  Yet once again, I would avoid this option rather than even the most generic brands cost dear.

  (8) remove the battery and run its own from the AC adapter.
  Tried, but it does not solve.

  9) play with the settings of monitors.
  Tried, but none of the settings fixed it.

  So, what are my options?
  Is there a known cause and the solution to this problem?
  If my laptop is still under warranty, can I get a replacement AC adapter / CC or something to work around this problem?

  Thank you

• Flickering screen on Satellite A100

  First of all, I would like to say hello to everyone...

  My colleague at work came to me with his laptop, which is a Satellite A100 with a screen flicker problem.
  Its nothing major, but the screen flickers constantly randomly as it s refreshing.
  I tried an external monitor and it is very good, so I guess that the LCD, 'FL inverter Board' or connectors. There is no distortion of colors, no lines/ladies on the screen and no backlight problem.

  I'm not a genius in laptops, but I fixed mine with success.

  I disassembled the computer laptop and just had a glance, made sure no loose connections, dust etc put back together and still had the same problem with the screen flicker.

  Now, I have no idea of what a "FL inverter board" is, or if this could be the problem, so any information would be appreciated.
  It s is not prepared to buy a new LCD screen, only to find out that it is this UPS widget.

  Thanks in advance

  I think that the FL inverter converts high voltage to power the Tube FL. You must be careful with the ups because it can give you an electric shock.

  You say that there is no problem of backlight, so it would not be the inverter at fault.

  If this is the Image that flashes (while the backlight is always on), then there may be a bad connection behind the screen, or a part should be replaced (for example, the LCD, the cable or the graphics card).

• Acer Aspire 7739 G flickering screen scratched grey/white

  Screen flickers badly during the splash screen for a few seconds before I can't connect. Also flashes once I'm connected, but not nearly as bad and only every few minutes. The computer is about three years old and has never been dropped to do this.

  Video: https://www.youtube.com/watch?v=RXEJPLfLZLw

  If you move the screen or press the framework along or near the hing, the LED flashes stop?

  If you enter BIOS at startup, press F2, the screen flickers still?

• Two screen question: Control Panel appears on the screen 1 but the mouse is on the screen 2 and so I can't access

  I have a Sony Vaio laptop connected to a stand alone monitor. I don't use the laptop screen unless there is a problem and then I had to alternate between the two screens using Fn F7 key.

  A problem has occurred with the rundll32 process (which I'm trying to fix separately) and this led to the PC automatically flicking between screens and then stick with the independent monitor but in low resolution (so I couldn't access the tool bar along the bottom).

  I went to control panel to change the resolution to high, but the question of rundll32 kept close the process.

  This left me with icons on the desktop of the monitor stand alone, a white color on the laptop screen (it is normally black) and the ease of Fn F7 does not (said the service is not available).

  When I click on Control Panel on the screen of stand alone, it opens on the screen of the laptop, but I can't access it because the function of the mouse is on the screen to stand alone.

  Can someone help before I go out drinking?

  Thanks, Temp.

  I seem to have solved the problem. It seems that display order has been reversed and so I just had to move the mouse to the right of the screen to stand alone (I had been pushing against the left hand side) to move on the screen of the laptop. From there on, I played a bit with the display settings in the control panel and, although the issue of the always kept dllrun32 throw me out, seems to be back on the screen of stand-alone only, with the correct resolution and the Fn f7 works again. This means I can put the top back on bottle of vodka, at least until the next issue of dllrun32 arises.
