Satellite C855-29N - HDMI Port does not

It was working perfectly before but now when I try the computer makes noise and seems to connect to the tv but there is no signal to my TV?

I wonder if it is a driver problem, but it looks more like a faulty connection which means that it is gone forever? :/

Pressing the function key F4 (Fn + F4) should change the screen output.
It does not work. Right?

Could be interesting to know if the graphics update driver / new installation would change something here have you tried it?

In the worst case, you will need to recover the laptop back to factory settings to check if its hardware or software related issue and I think that the problem of software.

    Hello

    > This problem start after a storm in my area some time ago.

    Because other devices don't work properly and because procedure didn t get it back help you solve this problem, I think that the problem is related to the hardware malfunction possibly that the motherboard was hit by lightning, which would explain the problems

    I think you should ask the maintainer authorized Toshiba in your country to check the motherboard.

    But in my opinion, that the warranty does not cover the issues of environmental impact maybe your household insurance could help you

  • HDMI port does not work

    Original title: HDMI port stopped working after the update.

    This morning my laptop did an automatic restart to install updates and now my hdmi port does not work. I tried to restore the system to a previous point, but that has not helped. I have a HP Pavilion dv6.

    I worked with a team of online crash analysis and they had update me of the BIOS. That fixed the problem and the HDMI port is now working again. For those of you who have the same problem, go to http://ftp.hp.com/pub/softpaq/sp48501-49000/sp48953.exe .

    Update your BIOS can help you too.

  • HP Pavilion dv6 Notebook PC: HDMI Port does not

    I updated my Windows 10 operating system and since that time the HDMI port did not work to my TV. This worked fine before the upgrade. I deleted the Intel drivers and installed the chipset as recommended on a previous post.  I tried another cable. It did not work.  The message on the TV is No Signal.

    Hi @Saxnot, @muzza180,.

    HP has worked closely with Microsoft on the development of Windows 10 and drivers for graphics cards. Currently there is no driver available for your system. You can try and check at a later date, because I see new drivers all the time.

    Thank you.

  • Satellite Pro P300 - output HDMI port does not

    Hi all

    Well it starts to drive me to distraction and Im hoping that theres someone who can put me out of my missery lol.

    I tried to connect my laptop (toshiba satellite pro p300) up to my LCD TV via the same HDMI cable that I use for my PS3 but the connector does not simply. I keep finding all these messages in various forums saying how they can't get the HDMI connection... that would be great, at least, this means that they were connected.

    Are there different links for the HDMI? The one I have is diagonal connector but the port on the laptop is more square and just doesn't fit. So, if it is not a connector, does that mean I have a funky port on the laptop.

    There is also the issue of connecting my laptop to my amp which controls the surround sound system. Which link is best to use, as there is no real connections audio output?

    See you soon

    Hello

    Can you please tell us what Satellite Pro P300 you have exactly? I mean the exact model number.
    Maybe you can also post a picture of the HDMI port. Normally there is no different HDMI port, all have the same physical size.
    I m PS3 not owner, but maybe he has a special connector. Have you tried another cable?

    Regarding the audio connection I use the normal line of output port to my external speakers. Have you tested this?

  • Satellite R830 - HDMI port does not work

    Hello

    Is there a driver for the HDMI for the Satellite R830 port?
    It is no longer connects to a TV.

    I tried different TV but still nothing.
    Also there is no HDMI in under the control panel Device Manager, should there be?

    Thank you very much for any help or advice.

    Hello
    I put t know what Windows system that you use on this laptop, but the driver HDMI isn't available from the HDMI port driver is part of the system and should be recognized automatically.

    Capacity Audio HDMI you need to install the right audio driver and should allow this in Control Panel-> sound-> playback device

    HDMI (digital out) would be not listed there, right click and choose:
    Show devices disabled, view hidden devices.

    Usually the HDMI connection isn t very delicate. Everything should run automatically.
    Connect both devices with a HDMI cable.
    Turn on the TV, then the computer.
    Now, use the exit function FN (key) video combination in order to get to the video (HDMI).

    Note: the correct HDMI channel must be selected on your TV

  • Satellite M300 - left USB port does not work

    Hey,.

    I have a M300 Satellite, with a USB port on the right and the other on the left side. The one on the left has never worked with anything. Its never bothered me until now - I bought a portable HD and I need to connect it and a mouse at the same time...

    Interesting note though that when I put the laptop HD in the left USB port, the led lights, hard disk. The lappy himself made no sign he knows its there and I cannot access it, however...

    Any advice? Thank you very much!

    I guess, it is burning or something like that. You can buy a USB hub, it's a device that develops a single USB port into several so that there is more available ports to connect devices to a host system. It's not expensive and you connect many devices.
