HP Pavilion dv7 Notebook PC: computer laptop HDMI to the TV does not

I have a monitor of Vizio that I was able to connect to my laptop via a HDMI cable last month.  I did it several times without any problems, but less than a month later I tried to do it again and it does not work.  The monitor says there is no signal, whereas before it was a direct connection.  I don't know what happened.  Help.

  • Dell computer laptop starts but the screen does not light

    Hello

    I have a laptop Dell older (studio 1558) and when I used it the other day, 'static' filled monitor image and then the screen went completely black.  Now when I turn it on, it seems that the computer starts well but the screen is black.

    Get yourself an external monitor, easy solution, right? -bad.  Unfortunately when I plugged my laptop in a separate monitor, the monitor (which works fine) showed no images.

    Still, I had this laptop for a few years.  I see about being 'easy' opening and closing of the laptop.  This has been the case in recent years, however, so I don't know if something has finally given...

    I'm not the best computer savvy so sorry if I was not more detailed... any ideas, what is wrong and how do I fix?  I rather would not somewhere that make me fixed.

    You will probably get a better response if you re - post it in the forum of the laptop and mention the version of Windows, too. (This is the forum office.)

  • Microsoft Bluetooth Notebook 5000 - I can click but the cursor does not move

    Greetings,

    I have a Bluetooth Notebook 5000 mouse that has a weird problem. It is well connected to my computer bluetooth, and I have all the updated drivers. Since last week, when I move the mouse, the cursor does not move (on the screen), but when I click on (either on the middle left, right, even scroll to the top and bottom), it works.

    My guess is that the laser under the mouse thing is probably broken. I tried different surfaces to see if I got any kind of reaction, but none works.

    Now the other problem is that the PID (as well as other numbers) number under the mouse is partially illegible due to wear. I can't see the last part of the PID.

    Anyone got any ideas? And is there a way that it could be replaced under warranty, even with an incomplete PID?

    Best regards

    Philippe

    Hello Philippe,

    Thanks again for the update.

    It is possible that there is a hardware problem.

  • Output STR - DN1030 HDMI to the TV does not

    The HDMI to the TV stopped working after a recent power outage.  I had the receiver for about 1 year and it has worked perfectly.  The inputs work fine.  Sound of DVR and BD are working properly.  However, the video output to the TV does not work.  I tested the cables and the TV by hooking directly to DVR & BD.  I had always hung on a surge protector and there is no damage to any other components.  I don't know what the problem is.

    I tried to reset the receiver as described.  It is passed by the method of COMPENSATION.  The output still does not work.  However, another problem arises.  The receiver and the display now rock SAT/CATV normal to LPCM [48] and DOLBY DIGITAL 5.1.  When the switching noise to cancel.

  • HP Pavilion Dv7-4285dx Entertainment computer laptop Wont stay turned on

    Alrighty this is one video of my HP Pavilion Dv7 - 4285dx Entertainment Notebook Wont work video. Basically, I can't understand what was lacking on this wise material issue (and if its even possible to distance just buy a spare part) or so badly need to buy a whole new computer altogether. Already have a portable game, but I'd rather have this laptop specifically for the armed forces when were allowed to use our computers civi make calculation on projects say. Any viable solution to possibly rebuild the machine, tell buy spare parts would be epic, but I can't determine what is the problem with it on my own.

    It may make more sense to look at the video that I can show what the machine is doing when I try to use it. Video--> http://youtu.be/KO4LAP2mJNM

    He's fine, the jist is that the machine is not turned on. The power LED flashes quickly, the F12 key light flashes quickly, light flickers hard drive read/write and the power on the portion sparkles. Also the battery is removed the iron on if this is a battery issue, I've already pulled out it is not not a bad adapter block. Regarding the power light, it's a constant light to solid white'.

    Someone at - it ideas?

    I understand that the system is off almost instantly after having turned it on.

    Based on the symptoms and the video, it looks like the motherboard has failed.  There are only so many components that can cause this problem.  The battery and Charger AC/DC have been rejected.  The laptop seems to receive a continuous power supply because the light stays on.  You could try reinstalling the RAM it could be just loose enough to trigger a security breach.  I doubt that is the case since that RAM in laptop computers is guaranteed to be generally quite good.  The disk HARD and WLAN module would not cause these symptoms.

    I know that's not the answer you are looking for, but the symptoms do not match that of a failed motherboard.  You could look into this and compare it to the costs and benefits of a new laptop.  Page 84 0f this guide details what is to replace the motherboard.  According to this, the part of HP for the motherboard number is 630985-001.  You might look online to see what the cost of a motherboard to a site selling online because it does not appear that HP is available.  You can can try the HP parts store because it is more recent than the surfing part.

    In most cases, the benefits of a new system outweigh the costs and the benefits to repair an old.  However, third-party sites can carry enough good parts markets to switch the balance.

  • Pavilion G6 2338sl: hardware button to turn off the touchpad does not work on Windows 10

    Hello

    I have a Pavilion G6 mobile 2338sl. When I was on Windows 8.1 the touchpad worked a lot, so I've updated for Windows 10. Windows updated my drivrs to last, provided also by Synaptics (19.0.19.1). HP says the moment is upgrade from Windows to provide the driver for this laptop, as you can see on the driver support page. The touchpad works, the parameters can be set (gestures etc.), the touchpad turns off when another mouse is connected (it's ok).

    The problem is that if I use the touchpad and I want to turn off the button, it does not work and the computer reacts like a click. So I returned to the old driver and button works. But Windows Update continusly updated the driver (I disabled the option in the advanced settings, but it still update) and I come to every time.

    So I tried to reinstall Wndows freshly (not update Windows 8.1) and with the old driver works, but when she updates to 19.0.19.1, the button to turn off the work stoppage.

    I looked on the interent and someone tips to set minimum detection of palm. I tried but it still not working.

  • Satellite L650 - HDMI to the TV does not work

    Hey there,

    I have a big prob. My HDMI connector no longer works for about 5 days.

    If I connect my Satellite L650 via HDMI to TV, the laptop detects the TV and identifies it as Phillips, which is quite right, but I don't get a screen on the TV. I have tried several cables and several televisions, tried to activate HDMI thanks to push "FN" + "F5" key, changed the resolution, nothing helps.

    When I connect the HDMI cable to my laptop, I hear that sound when a new device is connected. By pressing fn + f5, I can choose between vga and hdmi connector. My OS is Win7 64.

    Can anyone help? Thank you.

  • HP Pavilion Notebook - 15-ab04: some keys on the keyboard does not

    Hello

    Recently I'm impossible to insert the exclamation mark (SHIFT + 1) on all programs. I know there is no problem with keys like shift key works and the number 1 button also works. But when I press these two keys in combination that I get nothing (just tried to put an exclamation mark here without result).

    This problem happened with HP Win 10 laptop my father as well. Suddenly the majority (nearly half of his keys) has stopped working and it uses an external keyboard for 2 months (once more tried to put an exclamation mark here without result).

    Really disappointed because it clearly seems to be a problem of HP after what is happening to my and my dad HP laptop computers only.

    Can someone shed light on this you problem. Thank you.

    Good I manaeged to find the problem, I got an AHK script interefered with that somehow. So I removed it and it works.
