External VGA stopped working

Hi,
Approximately week or more ago my external VGA port stopped working - Catalyst control center detects new monitor attached, but there is no output signal (at least monitor says so). Monitor itself & cable is tested and works fine.
It seems that either it is hardware defect or recent windows update caused it. I am not sure how to test it. (Radeon drivers are dated back in 2009)
Config:
Thinkpad T60 (2007-66G)
WinXP Pro 32bit
ATI Radeon Mobility X1400

To raise the old topic...
I have exactly the same problem with my 8744-HCG model (T60 widescreen with ATI Radeon x1400). It seems to be a hardware fault (is not operating system or BIOS version dependent). I was however able to go around it by buying an "Advanced mini dock" docking station and using the DVI port. From DVI, the external display works fine. Therefore, my guess is that the video card has lost its capability to power up the analog VGA signal for the external port due to faulty in the circuits.

External mic stopped working on my laptop

I was in the middle of recording music and then the external microphone stopped working, this is the first time it has done this. And yes I have it plugged into the right jack I also have checked to make sure that it is unmuted, I thought that maybe somehow the driver unistalled itself so I got another driver and still nothing. But to be honest I have no idead what I am doing here people so please any help will be greatly appreciated.
Thanks
P.S.
I have windows 7 and the model laptop is a satellite L505-ES5018

same problem as me, I accidently deleted my driver (one word, brownies)
Is there any way to get them back? Maybe a driver download by mirror if someone can assist us it would be greatly appreciated. thanks

External Speaker stopped working - get sound through headset

I have a Zire 72. The external speaker stopped working. If I listen to music or voice memos through a headset, I can hear the message so the programs are working. I have tried a soft reset but no results. Has anyone had this expierience? Sounds and alerts all set to high in preferences.
Thanks.
Post relates to: Zire 72

The speaker cutoff switch may be stuck in the headset jack.
Try this procedure.
Turn the Z72 off. Get a non-conductive electrical contact cleaner (Home Depot has this in the electrical dept.)
Spray a few drops on the headset plug.
Insert and remove the plug in the headphone jack 5-10 times.
Wait several minutes for the cleaner to dry.
Power on the Z72 and see if the speaker works. If not, try the procedure again.

External speakers stopped working when Yosemiti was down loaded

My external speakers stopped working when I downloaded Yosemiti! how can I remedy this?

Dunno what it has to do with Yosemite, but: press the alt/option key, while clicking on the speaker icon at the right hand top of your screen. This will show you all the sound inputs and outputs for your mac. Ensure that it is set to "Line Out" or "Digital out" (depending on your speaker's capabilities. Hopefully
that works

External Speakers stopped working on Imac

External speakers stopped working. Verified speakers operating with Iphone. Checked that speakers plugged in correctly. Tried usual power cycling step. External speakers do not show up in sound preferences. Anyone with any advice?
Thanks,

If you unplug the speakers to the internal speakers work OK? If not try resetting the system PRAM see Resetting your Mac's PRAM and NVRAM
If they still don't work or if the internal works OK then look into the speaker plug. Do you see a red light? There is a switch inside the plug that detects the presents of a jack and sometimes it gets stuck or breaks entirely.
You could try gently using a non-conductive device (a toothpick is good) probing inside the plug to see if you can free the switch. Of course this could be harmful if done incorrectly. If the system is still under warranty you might want to take it to have it looked at.

Left external speaker stopped working

Left external speaker stopped working, right works fine. When I connect headphones, they work fine. Have tried two different sets of speakers, deleted plists and reset pram. Please help!

Hmm. I think its not a sound card and its not a speaker problem because both parts (left speaker and sound card) seems to be ok as you have posted in your message.
Im not quite sure what could be wrong but possibly this issue has something to do with the headphone jack there is a tiny switch inside the headphone jack which enables and disables the speakers if the headphone jack has been plugged.
Maybe this switch does not work properly.
What to say in such case the hardware needs to be replaced but in most cases the headphone jack is a part of the motherboard and in such case the whole mobo needs to be replaced and I think this is not worth because of the high parts costs

External monitor stopped working on Macbook Pro

I have a Macbook pro 15 with the vga adapter. I have been using it sucessfully for a month. Today it stopped working. I followed all of the suggestions online but have had no luck resolving this issue. The monitor works fine on my sony laptop but the Mac cannot see it. I have unplugged the adapter, shut down, turned on and plugged it back in as recommended. I tried a different monitor and i have simply restarted the machine with the adapter plugged in. I would greatly appreciate any suggestions.

Try doing a Parameter RAM reset - hold down command/option/p/r keys at start up and wait for three chimes before releasing the keys.

External monitor stopped working after 10.6.7 update

I have a MacBook Pro, model identifier MacBookPro6,2 with an NVIDIA GeForce GT 330M.
When I updated last night from 10.6.6 to 10.6.7 I stopped being able to use my Dell S2409W external monitor.
I have tried resetting the pram, resetting the SMC, booting with extensions off.
When I plug in the cable to the external monitor the Mac screen goes blue for about 0.5 second and re-appears but nothing displays on the external monitor; a second monitor is not listed in the Display preferences and the monitor reports that it is not receiving a signal.
I don't see anything in the system.log when I plug or unplug the monitor cable (I'm not sure if I should).
At random intervals while the external monitor cable is plugged in the screen goes blue for a half second and then re-appears.
The screen does not go blue if I wiggle or flex the monitor cable.

I see this in the windowserver.log after reboot, login with shift-key, and the external monitor connected.
There might be a clue here but I don't have anything to compare it to since I haven't collected these data when the external monitor was working.
I'd be curious to see the same data from the windowserver.log for somebody else with a MacBook Pro with an external monitor connected that does work.
You can view this log with the console application located: /Applications/Utilities/console.
If you are willing to share these data please reboot, and hold the shift-key down when logging in to disable extensions (thanks). If you look at the time just when the desktop appears when you end up looking at the windowserver.log you'll be able to see the windowserver starting up about 10 seconds prior to this time.

After LR 5.3 update external editors stop working. PS , NIK collection

I updated lightroom from 5.2 to 5.3 and my external editors NIK and Photoshop CC stop working. I click on them, but nothing happens the applications do not open. In the case of Photoshop I make sure that I had everything updated including camera raw to match lightroom's 8.3

OMG!!! Thank you so very much!!! I went ahead and checked in preferences and the store preset was unchecked, so I checked it "on" to see what would happen. It took NIK off the edit tab, but it still showed photoshop, so I clicked on Photoshop and it worked!! The file was exported to Photoshop, so I went back again and unchecked the box and the NIK collection came back to the edit tab and it started working!!! So thank you so very much!!!

External Display Stopped Working

I've been using an external Dell 19" monitor with my beloved and faithful Macbook Pro for years. All of a sudden, I was unable to select the propert setting for the external monitor. Two days later the monitor stopped working altogether when plugged into the Mac. The Mac screen acts like the other monitor is working, but there's nothing on the external screen. The Dell monitor tries repeatedly to turn on, but the power button repeatedly changed from amber to blue while saying it's entering power save mode and never turns on. I've tried changing screen savers as recommended on another forum to no avail. I also ordered a new mini-DVI to AVG connector in the hopes that is the issue. I've confirmed that the Dell monitor still works fine by connecting it to my old PC, so that's not the issue. Any advice is appreciated. I read copy for a living and really need the larger display. Thanks!

External monitor stopped working!!

My external monitor just stopped working today as soon as i upgraded to Mac OS 10.6.4 from 10.6.2.
When I unplug it and plug it back the screen goes blue very briefly but then nothing happens.
I tried the detect display button, I tried resetting the PRAM and nothing's working.
I really need to get that monitor to work. Help would be greatly appreciate.
Thank you

Yep, have the same problem using a 3rd party cablesson mdp-hdmi adapter. Everything worked fine until quite recently. I have tried pretty much everything to fix it but nothing seems to work. I'm almost convinced it's an OS problem, as everything works fine when I boot into my windows bootcamp partition.
Apple, please get this sorted! I'm reluctant to shell out $35 only to find that I have the exact same problem with the official adapter. Though I probably will anyway because I urgently need to get my display working again.

CX623 external monitor stopped working

Hello everyone,
we have a CX623 which has worked fine for years. This week the external DELL monitor stopped working. It just goes into power save mode.
The monitor and cable work if plugged into a different laptop.
A different monitor which is ok doesn't work when plugged into the CX623.
So it's 100% an issue with the laptop. Pressing Fn+F2 to change the monitor configuration doesn't resolve the issue.
The laptop does recognise the monitor and correctly names it in the display resolution settings.
Any suggestions please?

That really sounds strange....most likely it's something internal to the notebook. And honestly, there probably isn't any easy way to fix it other than replacing the motherboard.

External speakers stopped working

My Macbook Pro (Lion) was working fine on my external speakers with one sound jack from the speaker box, it stopped working, my headphones will not work either. The external speakers and headphones work on my PC no problem.

External speaker stopped working

My external speaker on my i-phone 4s stopped working suddenly. I was told to hold both the round button & the start up button together to reset. This seemed to work for a half a second, then it cut right back out again.

which speaker? the phone may be stuck in 'headphone' mode, try plugging and unplugging the headphones a couple of time. just in case-there is only 1 speaker on the bottom of the phone, the other is a microphone.

Hey coolasc,
If you had a lot of updates come through, you'll want to make sure that BIOS was one of them.
BIOS stands for Basic Input/Output System/Service. It is the language that all of the hardware components in your computer use to communicate with each other. There are updates which come out periodically for it so it would be best to have the latest version. The following steps were taken from here.
Windows 8: From the Start screen, type "msinfo32". Click msinfo32 from the list of results.
Windows 7&Vista: Click the Start button, type "msinfo32". Click msinfo32.exe from the list of results.
About halfway down on the right, look for BIOS Version/Date.
3. Copy and paste the information to the right of BIOS Version/Date in the value column, into your reply.
The latest version on the HP Drive Page for your particular notebook is F.66. It could be that a lot of updates other than BIOS came through and BIOS just hasn't come through quite yet (if this is the case, it would be fine to manually install the latest version). If you have a version higher than F.66 by some chance, go back to F.66 by just downloading and installing it.
The BIOS being out-of-date or just out of sync with the other updates that came through, could definitely cause an issue like this.
Please let me know if you have any questions or if these suggestions helped (this could help others with the same issue). I'll keep an eye out for your reply!
