My HDMI port doesn't work

Hello I upgraded my windows to 8.1-64 bit and after that I found out my HDMI port and Bluetooth doesn't work , from this page I download Intel High-Definition (HD) Graphics Driver which finish installing with a error that says---------------------------
This computer does not meet the minimum requirements for installing the software.---------------------------
also I downloaded Qualcomm Atheros Bluetooth 4.0+HS Driver for Microsoft Windows but nothing happend , in the other hand I am prety sure that my product bluetooth is Intel® PROSet/Wireless Software for Bluetooth® technology (it was previous windows driver) that I downloaded it from this link and it didn't work.I'd appreciate it if someon help me.procuct model: pavilion dv6-6c55se

Hi: I don't think you are going to have any luck running W8.1 on that machine. The Intel graphics driver won't work because you have the custom AMD/Intel switchable graphics and only the AMD driver should be used for that setup as it also contains the special Intel graphics drivers needed. You can try this W8 driver for the graphics, and if it doesn't work on W8.1, then game over. This package provides the AMD High-Definition (HD) Graphics Driver and Catalyst Control Center for supported notebook models that are running a supported operating system. For notebooks with switchable graphics modes, this package includes drivers for both graphics processing units (GPUs). Switchable graphics enable users to switch between a power-saving graphics mode (normally used under battery power) and a high-performance graphics mode. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. File name: sp59850.exe The Intel bluetooth...you posted a W8 driver. I would try the W8.1 driver... https://downloadcenter.intel.com/download/23449/Intel-PROSet-Wireless-Software-for-Bluetooth-technology-for-Windows-8-1- If you are unsure as to what bluetooth driver you need, you always install the corresponding model bluetooth driver for the model wireless card your notebook has. So, if you have an Intel wireless card, then you install the Intel bluetooth driver. If you have an atheros wireless card, then you install the atheros bluetooth driver, and so forth.

I updated to 10.4.7 and now my left USB port doesn't work

Hi all,
I ran Software Update just a second ago, installing an update to MacOS (PowerPC), ITunes, and QuickTime. After the install and the restart, my left USB port is no longer working. It was working immediately before the install.
I have verified that the peripheral that was not working in the left port works just fine in the right one. I have also confirmed that a peripheral that was working previously in the right USB port doesn't work when attached to the left one.
Therefor, I am led to believe that the problem lies in the left USB port. The only thing that has changed is the updater which ran moments ago, and again, the left USB port was working just fine prior to the install.
Has anybody else experienced this problem and knows of a fix/patch/anything I can do?
PowerBook G4 Titanium Mac OS X (10.4.7)

Welcome to the Apple discussions.
I would reset your power management unit, then install the combo 10.4.7 update. Recently, there have been issues with updates through the software update function.

Audio out port doesn't work well

Hi, I have a Macbook Pro 13-inch, Early 2011. Since I bought it I always use my Mac whit headphones, but since a month it only works well the left headphone. I think that the problem it was my headphones but no, because I used it on my phone and workes well. So i come to the conclusion that the audio out port doesn't work well. What you think? And what you recommend to me to fix this problem?

Probably still under warranty, but not for long. Take it to the Apple Store or AASP to have it checked ASAP.

HDMI, Headphone Jack, Ethernet port doesn't work after lightning strike

I have a Mac Mini mid 2011 model. After a recent thunder storm/lightning strike the ports mentioned doesn't work anymore. Do I have to replace the whole logic board to get it working again? What are my options in fixing the mini? Luckily, I'm currently using a Thunderport to HDMI, a USB adapter for sound, and USB to Ethernet for internet. The mini still starts up as well as everything else, but those three ports were hit and are no longer responsive.
Any suggestions or ideas would be greatly appreciated.

Unfortunately. This is why I never leave my computer plugged in to power or electrical devices when I leave the house in any sort of unpredictable weather situation that may include lightning. There is no surge protector that can protect against a direct lightning strike.

Dr. Bott Mini DisplayPort to HDMI cable doesn't work.

I'm trying to connect my MacBook (mid 2010) with my tv and I can't get it working properly. I have the HDMI cable, and the mini display port to the HDMI cable. When I connect the computer to the tv, the computer screen turns light blue like it is about to synchronize, but the tv screen remains black. After a moment, 2 boxes appear on my tv screen. One says "HDMI1: and the other "no signal detected".
I've tried with "detect displays", I've tried connecting to all the HDMI ports I have on my TV, I've tried basically everything but it still doesn't work.
This is the adapter - http://www.drbott.net/product/7395-MDPA/
My TV is a fairly new Samsung, and everything else is working fine, I don't know why this won't function. It's frustrating me.
Any help on this matter would be greatly appreciated. Thanks.

When I have this problem, it is because my Macbook Pro is using "Integrated" graphics vs the "Descrete" graphics. I control this via the gfxCardStatus menubar utility.
You could also try reseting the smc controller
<http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US>
and/or resetting the PRAM

HDMI Port doesn't recognize TV

I have a Satellite L735 laptop with Windows 7.
I'm using the same HDMI-to-HDMI cable I've always used in other computers. This time I wanted to connect my L735 to a Samsung LCD TV.
First time it worked perfectly. Disconnect cable from both devices and go to sleep.
Second time, the TV doesn't detect any signal in any of the 2 HDMI ports. And the laptop never gives me any signal or message at all. It doesn't even make the "device connected" sound Windows usually makes.
It's like I haven't connected anything at all. Tried the cable with another PC to the same TV and it worked, so the problem is in the laptop.
What could be causing this?

I am having the same problem with my Satellitte P745-S4217, running Windows 7. The RGB output works fine, but HDMI does not work at all. I tried connecting an HDMI cable to a regular HP Monitor (HP2311xi) to the laptop also, and no display. The cable and HP monitor are fine, because they work with another computer.
I checked both the speaker control and tried to find any indication in that any system was recognizing the HDMI and found nothing.
It appears from all the complaints scattered around the vaior groups that Toshiba has a basic problem in a defectively designed HDMI output, and so far has not found any work-around.

I cannot use any external monitor, it appear like the port doesn't work , i'm using the mini-dvi port with a VGA adaptor ,

I've always used the port normally with different monitor but by a couple of weeks it appear like no signal come out.
Does Anyone knows what can i do ? i.e. How to check or reset the Mini-dvi port ? or if there's any key on the keyboard that can habilitate it or not ?
Any Help will be appreciate
Thanks

Welcome to Apple Support Communities
You don't have to do anything to make the port work. Reset the SMC > http://support.apple.com/kb/HT3964
If it doesn't work, try with another monitor to see if it works or another cable. If you haven't got another display, take the MacBook Pro to an Apple Store or reseller, so Apple will test the port and see if it works correctly

Rocketfish Mini DisplayPort to HDMI Adapter doesn't work

I recently bought a Rocketfish adapter for my late 2010 Macbook Pro and it doesn't work on my TV. I'm going to try swapping it out tomorrow to see if that's the problem, but just in case it wasn't, I thought I'd come and ask someone who'd know the answer. The TV is an Insignia TV, the HDMI cable works - we use it for out BluRay player - the adapter just...doesn't work. When I turn the TV on, my screen briefly goes to a light blue, then back to my normal desktop. Mildly frustrating that this won't work. Anybody have any advice they can offer?

CLICK "SYSTEM PREFERENCES", THEN FIND AND CLICK THE "DISPLAY", GO TO AND CLICK THE "ARRANGEMENT" AND CLICK "MIRROR DISPLAY" PROBLEM SOLVE GUARANTEE, AND ON THE AUDIO PROBLEM, GO TO "SOUNDS AND CLICK "HDMI" OR "VGA" IF YOU ARE USING VGA CORD. NO NEED TO UPDATE THE SOFWARE. WORKS LIKE MAGIC.

MacBook Pro closest to the screen USB port doesn't work

Hey there!
I have a mid-2010 MacBook Pro 6,2 (15" 2,66 GHz i7 4GB RAM) which is in perfect conditions. I use it everyday to study and play the X-Plane simulator, basically, so it has never fallen nor taken any damage. Last week, all of the sudden, the USB port located closest to the screen stopped working. I've spent several hours trying to figure out what the problem is (tried the SMC and NVRAM reset more than once) but all I got was this log from USB Prober:
Feb 12 21:46:26.196 [2]
BRCM2070 Hub[0xffffff800bcc0c00]::DeviceRequest _DeviceRequestWithTimeout runAction() failed (0xe00002ed)
Feb 12 21:46:26.197 [3]
IOUSBDeviceUserClientV2[0xffffff80151f7200]::DeviceRequestIn (sync < 4k) err:0xe00002ed (device is not responding)
Feb 12 21:46:26.197 [3]
IOUSBDeviceUserClientV2[0xffffff80151f7200]::DeviceRequestIn < 4K to 0xffffff800bcc0c00 - returning err e00002ed, size: 0
I imagine that the problem is in the BRCM2070 Hub, as it's status in the "Port Status" section is "STATUS(change): CONNECT ENABLE SUSPEND POWER Full Speed" and "Port Power State: Suspended (Driver)", while my other USB port which is working okay is "STATUS(change): POWER Full Speed" and "Port Power State: No connection". If I connect anything to the problematic USB Port the status won't change, while, if connected to the okay one, it will show what's connected instead of saying "No Connection" (e.g. iPhone). The only thing that gives a sign of life when connected to the problematic one is my Samsung External 500GB HD, but it simply lights up, doesn't mount nor is recognised. After a minute it turns off while still connected. I don't know how to proceed as I don't have any Apple Stores near me.
Is there anyway to work this problem out or I should just wait until the end of this year to go to the US and take my machine to a Genius? This problem is really annoying me, as I frequently use one of the ports to charge my iPhone and the other one to connect my mouse. I'm thinking about buying an USB hub to bypass the problem, but it would kill my MBP's portability.

I solved my issue and I believe it was router related. I have a router through Verizon and their Fios service. My router was old so I caled for a replacement. when I received thereplacement I switched it the router to only accept 802.11n and this did the trick. Problem solved, stupid router.

WRT400N WAN port doesn't work.

Nothing that I connect to the WAN port seems to get the internet LED to illuminate. I have a DHCP access to a Motorola CPEi 150 which works great if I connect to it directly with a netbook or if I use a dlink WRB-2310 router but it doesn't ever seem to register with the WRT400N WAN port. I've even tried connecting the WAN port to the dlink and still no LED or address from the DHCP server. It's a recently bought this Linksys-refurbished router and I think it will cost more to send it back that it cost to get. Is there an easy way to determine if the WAN port works at all without constantly disconnecting the internet in my house as family members are getting a bit upset with me.

I tried connecting a LAN port to the WAN port and it worked. I then connected the WAN port to the LAN port of a DLink router in series and I could communicate with the internet. I then connected it directly to the Motorola CPEi 150 and the port showed nothing. I then tried to repeat my steps and could not get any responce on the WAN port even with rebooting the router and reverting to factory defaults. The WAN port appears to have intermitten problems. I will attempt to troubleshoot some more but I may have to give up.

Dynex DX-LCD32-09 HDMI ports / inputs not working

My Dynex DX-LCD32-09 is just over a year old. It stopped recognizing anything plugged into the HDMI ports today. Not only that, every time the TV starts it goes to the TV input and displays the message "Please run channel auto scan" regardless of which input it was working on before it was turned off. VGA and A/V video is working fine when input is selected, however, once the TV is turned off and back on, it goes back to the TV input and th message about auto scan. I am assuming everything besides HDMI is working but I have only tested VGA and component.
I accessed the service menu and did an EEPROM Initialization (EEPROM Init) but that did not fix the problem. The Software build is 03/20/08 21:17:35 . Is there a way to update the firmware and will that fix the problem? any other suggestions? Can I take to bestbuy for repair? How much will they charge to Diagnose + Fix the problem?
Please help, playing PS3 on A/V port sucks!!!
thanks

Still no ideas ?

Qosmio X70-A-11Q - HDMI Monitor doesn't work

Hello
I work on my Laptop with 2 external monitors. One is connected via VGA and the other via HDMI. That all worked fine until yesterday where my HDMI monitor couldn't be found.
Things i already tested:
I tested the moitor by connecting it with another computer and it worked (with HDMI), so the monitor can't be the issue.
I also tried an other HDMI cable...didn't work ether.
BIOS is updated to the latest version
graphics driver from NVIDIA graphics card and from the standard intel graphics card are updated to the latest version.
Also a strange thing: when im in the BIOS menu while having VGA plugged in the screen keeps turning black for 1-2 secounds and then turning on again
Would be great to get some tips on what i can do :)
thanks

Hi
Are you able to use the HDMI out port without connecting another additional monitor to the VGA port? Please check this because from my experience it should be possible to use either the VGA or HDMI port.
However, I think the problem might be related to one of the graphic card driver.
Why? Because I think that one video out port would be controlled by one graphic chip.
In case you are using two monitors at the same time (VGA and HDMI) one video graphic card (nVidia or Intel) would control VGA port and the other HDMI port.
I think you should reinstall the Intel display driver.
First of all you should uninstall the installed Intel display driver from the system (do that in device manager). Then you should reboot the notebook. On the Toshiba EU driver page you would find the latest Intel driver v10.18.10.3308
This driver is released for Win 8.1 as well as Win 8 and Win 7
Would recommend you to install this version to fix the HDMI problem

IP automatic for WAN port doesn´t works

Hi, I have a RV042 with latest firmware (4.0.4.02) and I´m trying to conect to Internet in port WAN1 with the optino "Obtain an IP automatically". I have noticed that the router receives an IP from the modem, I´m able to connect to the from a PC in the same WAN subnet to the WEB Management page, but in the system summary the Wan Status is IP address 0.0.0.0 default gateway 0.0.0.0 DNS 0.0.0.0 and the pc in the internal LAN couldn't surf Internet.
The only way is assigning an static IP an DNS servers, and then all works fine.
On the system log shows the message "infinite IP address lease time. Exiting" when activate the IP automatically for the WAN1 connection type.
There is no option to change the leased time.
I need to send a router to a remote office where the connection to INternet is with a dynamic IP. Help please

I tried connecting a LAN port to the WAN port and it worked. I then connected the WAN port to the LAN port of a DLink router in series and I could communicate with the internet.
