Thunderbolt display has power but no picture and no USB power

I've had my TB display working well with my Macbook for a while with no problems. This morning I started up the MacBook but the display didnt respond and the USB ports do not seem to be working. Keyboard and mouse both work when plugged directly into the MacBook but not when connected to the display. The MacBook is charging from the display so it has power, but nothing else seem to be working. Any ideas, or am I looking at taking it in to the local store for repair?
Thanks,
DB

First try 'resetting' the Display by disconnecting it from mains for about 15 minutes and then plugging it back in. I've only had the problem that you describe once and this was the 'fix' for me.

Thunderbolt display not recognized - but only after supper!

Ugh. Getting seriously frustrated with my 27" TB display, now. Have been using it on a MBP 2011 for a while, had experienced some flickering with Lion, not so with ML.
Last week, I left my MBP connected and went in for supper; when I came back, the MBP had - of course - fallen asleep. Woke it up, but only the MBP display came on, not the TB display. I unplugged/replugged, several times - same thing.
Rebooted the MBP, with the TBD plugged or unplugged - same thing.
SMC reset - same thing.
I spent two nights reading forums and trying all sorts of fixes - no luck.
Finally, I resigned to booking an appt with the local Apple Store; this appt was for this morning. This morning, before getting the monitor out of the office, I decided one more time to connect my MBP - it worked!!! ***?
So I worked all day, no issues. Very happy.
Tonight, before going in for supper, I unplugged the monitor and closed my MBP's lid so it would go to sleep. When I came back, I woke up the MBP, connected the TBD, and...nothing. Black screen!! Went through a couple of rigamaroles to try and get it back - nothing!
Argghhh!!
So now, I'm wondering if my diet has something to do with it. Tonight, I had T-bone steaks on the grill, with roasted potatoes and a salad. Maybe if I would have had pasta instead the monitor would have gone back on?
Any ideas, suggestions or magic spells would be greatly appreciated.
As would a fix from Apple...

I have been having the same problem since I got the **** Thunderbolt display and a lion-installed macbook pro in September last year. I've been sitting tight thinking surely Apple will fix this debilitating defect on their premium equipment - How wrong was I!
My story is similar in that I always take the laptop home from work and have the Thunderbolt display in my office at work. I close the lid putting the laptop to sleep and pull out the cables. When I go home I may use the laptop via its internal display (one would think that would be ok) and then close the lid and put it back to sleep. WHen I return to work, plug in the cables and open the lid, most of the time the thunderbolt display stays black. On a rare occasion it will switch on but I can't fathom any pattern as to when and why it might work. The only solution to get the display to switch on is to reboot the laptop (and lose all my open documents from work the previous day and night). Recently, and I'm not sure what has triggred it, things have got a whole lot worse. Now, if I reboot the laptop when connected to the unresponsive screen upon restart the Thunderbolt display freezes on a grey screen and the laptop display stays black. The only solution is to hold down the power button and force shutdown the laptop. This happens everytime now, I simply cannot reboot the laptop with the thunderbolt display attached!
Nice premium equipment Apple! As this stuff was bought by my work I have learned to live with it. If had bought this junk with my own hard-earned then I would be furious and would have demanded a refund/replacement/explanation a long time ago.
Maybe, just maybe, Apple may one day actually fix this £2000 setup I have sitting on desk so that it switches on when its supposed to. Is that too much to ask?

I am recording with Logic Pro X, using my Yamaha XS8 keyboard as a Midi controller. I also have a Thunderbolt Display. Every time I play and release a note on the keyboard, the Thunderbolt Display speaker emits a doink sound. How do I get it to stop?

I am recording with Logic Pro X, using my Yamaha XS8 keyboard as a Midi controller. I also have a Thunderbolt Display. Every time I play and release a note on the keyboard, the Thunderbolt Display speaker emits a doink sound. What is causing it and how do I get it to stop? My sound is running through the Saffire Pro 40 Interface (Focusrite) into external speakers with powered amps.
Also, When I record I am hearing little pops in the system. I have checked all of my meters and they are not clipping. What is causing it and how do I get it to stop?

Pancenter,
Thanks for the response, but I do not have a midi interface. I am using a midi to usb connector cable, thus bypassing the need for a Midi interface.
The Mac reads the USB cable as a midi device, but not the keyboard that I am trying to use as a controller. I have tried it with my korg sp 300 and with my Nord Electro 2.
Thoughts?
Thanks,
Tristan
Tristan...
This is what you have, correct?
http://www.alesis.com/usbmidicable
This from Alesis..
"The AudioLink Series USB cable receives and outputs MIDI signal thanks to its internal interface. The USB-MIDI Cable connects plug-and-play to your Mac or PC for an all-in-one USB-MIDI solution."
Notice, -internal interface-. What you have is a simple USB MIDI Interface. Most MIDI interfaces are USB.
My point is (was), MIDI OUT of the Korg goes to the connector marked MIDI IN on the Alesis, those new to MIDI often get this wrong.

Tv has sound but no picture

My hp tv model # PL5060N has sound but no picture tv is wall mounted

Have you tried adjusting the "Audio Out" and the "Dolby Digital" settings in settings > audio and video? It may be worth trying several combinations of these settings, although typically it is the "Dolby Digital" setting that causes most problems for users.
If you are using a sound system/receiver, make sure that you have correctly mapped the input port on your sound system to the output, if you are unsure about how to do this, refer to the manual that came with your sound system.
Have you tried playing various content sources (i.e. podcasts, music, iTunes Store video, other video etc), do you have the same problem with all types of content? If you use optical you might also check that you can see a red light at the end of your optical audio cable. Is your optical audio cable plugged straight into your sound system, or does it go through a switch or other device?
If the problem persists....
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Reset the Apple TV (Settings > General > Reset > Reset all settings)
Restore the Apple TV (Settings > General > Reset > Restore)

Satellite L750D - Window Media Player has sound but no pictures

I have a Toshiba Laptop Satellite L750D, Win 7 Home Permium. I don't know why Win Media player just has sound but no pictures. Please some one help fix this problem. I don't have a recovery dics. Where can I down load it? I would very much appeciate your help. Hien

Your issue is likely, but not necessarily a corrupted or missing codec since you haven't actually confirmed whether your problem is with just one disc or all discs nor if they ever worked on this system before.
Installing VLC is a good idea, but it's a considerate application and won't tamper or try to repair a busted codec and will more often avoids tampering or accidentally repairing any detected whether it's already working or likely broken like yours. That's one of the reasons VLc is so highly recommended such as they way it was repeatedly suggested to you.
A question to ask if your problem is being caused by a few discs, are they custom burned or commercially pressed boutique films since most mainstream DVD's use the same MPEG-2 codec for video and audio and failed video but working audio is usually a clue about a split format disc that has simpler audio streams but obscure video formats that can result in an issue just like yours.
In either case and if none of that is of interest, I can relate and suggest you keep any installed VLc's and download KLite because it is nothing but varying degrees of CODEC's including obscure ones and is fairly aggressive in detecting and seamlessly repairing corrupted codecs while offering more configuration options than most people want and more than many commercial video applications offer.
Visit http://codecguide.com/download_kl.htm and choose the "Mega" or 64Bit package but 64bit systems can successfully backport the 32bit set if you feel its necessary to.
You can also potentially skip the KLite process by diagnosing your codecs with Nirsofts InstalledCodec tool, a single file executable no install / no reboot but I don't get the impression you're prepared to really do much at that level and that's fine but it might be needless effort in your case.
http://www.nirsoft.net/utils/installed_codec.html
But something you definitely need to stop and wonder about is what happened to crush your codec since they don't normally suffer damage until some insidious piece of badware like your favorite iLivid and mine gets into your computer to raise holy hell forever. If that could possibly be what happened to you, the circumstances of how you managed to pick it up and anything else are things you can keep to yourself but consider it a spyware affliction and one I don't make lightly and is something I rarely suggest since it is the overused excuse at the Microsoft forums to blame everything on spyware instead of poorly written OS code.

I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?

I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,

How can I use an external display with my MBP lid closed and disconnected to power?

I know that I can use an external display when my MBP lid is closed and it is connected to power. I was wondering why it does not work when the power cable is removed.
I only use an external display when I am at home so my MBP acts like a Mac Pro or Mac Mini in that way, but it is not good to leave the battery charging constantly on a MBP so I want to disconnect the power and use external display and have the lid closed. Is this possible or do I have to leave my lid open when running on battery power?

I'm plugged into my wall socket at least 90% of the time - probably more. I always make sure that I take my MBP off mains about once every two weeks and let it run down to about 30-40% and then plug it back up. This keeps the ions flowing and the battery healthy. My MBP will be one year old on March 20, 2013, and my battery health is still at 99%. I run in clamshell mode most of the time now - since I bought a 27" Apple Thunderbolt Display. Only occasionally am I off mains - and then because I'm exercising my battery, usually.
Don't worry about running of mains most of the time - just be sure and unplug about once every two weeks (or twice a month) and let your battery dip to the 30-40% mark and you'll be fine.
Good luck,
Clinton

How do I share a Thunderbolt display between a 2011 MacBook Pro and 2011 MacMini?

I'd like to share a Thunderbolt display with my MacMini and MacBook Pro. The MacBook would presumably be connected periodically via the Thunderbolt / power cable from the display. Can I connect the MacMini via the Thunderbolt port on the back of the display?

Noooooo... The statement you have as a correct answer is INCORRECT!!! I'm not sure where Smudge got that idea originally from, but it is NOT the case.
@ericfromoak ridge: PLEASE Remove that as correct so that other users don't read and believe that!!!
Basically, if it's a Thunderbolt port... it contains both the PCIe (data) and DisplayPort (video) information.
Just from the Apple website alone it shows otherwise...
http://www.apple.com/displays/
In their example (from apple page), it shows (1) MBPro connected to the first TB display (via built-in cable... you can see this because it is the combo-cable with both the TB plug and power cable). Then the 2nd TB display is connected into the back of the 1st display. There-by "Daisy Chaining" and also showing that TB devices can plug in and work in any order... and that VIDEO (along with data) is still passing thru (bi-directionally) via the backport. No Difference.

In regards to your original question...
- Do BOTH of your machines (your MacMini & MBPro) have Thunderbolt capabilities? If either one or both don't have TB on the computer, you will Not be to run the scenario you are trying.

17!" Studio Display connected & recognised but no picture?

Hi I have an iBook G4 & have connected it to a 17" Studio LCD.
It shows up in "about this Mac & in System Prefs/ Displays but no picture.
When I press the power touch sensitive swith on the front that lights up white.
Same when I touch it again. Hard to know when it's on or off because nothing else changes. Black dead looking screen.
Any ideas what the problem is?
It was working fine on my friends MacBook.
I bought an adapter for it & the fact that it is recognized makes me think the connection is OK but why no pic?
I've not used an external display before.
Is there something I'm missing?
What to do?
Thanks

Thunderbolt Display has issue with weird washed-out colors after waking from sleep (after upgrade to Mavericks)

I've got a Thunderbolt Display that I use with my Macbook Air (mid 2012) - usually in clamshell mode.
When I let the computer go to sleep, and then wake it up by clicking the mouse, the monitor turns back on but the colors are washed out and purple looking.
The display goes back to normal when I unplug and replug it to my laptop.
I first noticed this problem after upgrading to Mavericks.
I made a video demonstrating the issue here:
http://www.youtube.com/watch?v=19179-MVpWA&feature=youtu.be
Any ideas?
Thanks!
Will

Same thing for me too. Late 2012 13" MBP Retina. I have to unplug the Thunderbolt cable and plug it back in.
This has only started for me in the last two days. The first two weeks of Mavericks was ok.
Update: I just got back from a trip. I was using the laptop separate from the Thunderbolt display. I hadn't restarted since I returned and connected the monitor. I've just rebooted, and put the computer to sleep. After resuming from sleep, the display is ok. Maybe try rebooting? I'll update if it continues.

Thunderbolt display has stopped working with my mac mini

I purchased a brand new thunderbolt display and mac mini a couple of months ago, and now the thunderbolt display no longer comes on when I start the mac (I am only able to type this here because I pulled out my old monitor and plugged it in to the mac mini via hdmi port, which seems to work just fine).
I have so far shut down and re start my mac a couple of times. I have unplugged everything and started them back up a couple of times, but nothing seems to work. How can I get this fixed? I have to admit that I feel like a shmuck for paying this much money for a monitor and then have it stop working.

If you haven't done so already, try resetting the printing system.
OS X Mavericks: Reset the printing system also Yosemite
Is the printer attached to the computer or is it a network printer?

VOB has sound but no picture (gulp!)

Hi
I have transferred a video tape to a DVD and it has come across as five .VOB files.
I can load the last four into Adobe Premiere Elements 7 but the first produces the message 'This type of file is not supported, or the required codec is not installed'. This is trange as the other four work fine. I truied renaming the file to a .mpg file and the same message occurs. When I play the file in Windows media player it play with sound but no picture.
Can anyone shed any light on this please?

Rory,
Good luck with the pass-through on the videocam. That should work fine. The one hesitation that I have is that many mfgrs. omitted pass-through on their PAL models, as most of Europe have a higher VAT on a camera with it. Seems that legally it is declared as being another type of device, and the tariffs were higher. Many NTSC versions of the same camera did have that capability, but the same one for PAL-land did not. Now, many mfgrs. are just omitting it completely, to save $ with that circuitry, especially in light of the PAL tariff issues. Some have found that just picking up a used NTSC version has worked fine - they do not use it to shoot, but only as an A-D bridge with the pass-through. Hope that yours works perfectly, and that it will fill the bill.
As for the OZ whites, I have only encountered one, the Penfolds Yaterna, that did anything for me. In very general terms, I find the whites from NZ much more interesting. Now, I do find them to be great "sippers," but the herbaceousness and the grapefruit notes seem to get in the way with food. Still, a Cloudy Bay SB is such a great Summer wine (in AZ, USA, we need "Summer wines," about 9 mos. out of the year!). I love that grapefruit, though my wife is less a fan. She is also more enamored by a bigger French Chard, than almost any SB.
I had maintained many, many years ago, that NZ was going to be a PN center. That is being realized now. However, I do have to keep looking hard to find them. Some California restaurants are starting to explore them on their wine lists, but with some of the recently developing areas in CA doing some great PN's (Santa Barbara, Santa Rita, Central Coast and Napa/Sonoma in the Carneros AVA), it is a battle - lot of good PN's out there, as soon as one gets over the US$ 25-30/btl. range. I have yet to really see the value of PN's much below that price point. Probably some out there, but they are few and far between.
Here is an ongoing Shiraz THREAD in the Adobe Video Lounge. Here is an older THREAD on PN's from there. Here is a short Syrah THREAD. Some good discussions in the Lounge. In a similar tone, I am in a Photoshop/photography thread on Chowhound. It started with the question - what camera to do food photography. Along the way, one poster came out bashing Photoshop, and then went on to bash Photoshop Elements. I could not let THAT go on, so have been trying to stem the flow of mis-information being spewed in that thread. Now, I am not saying that Photoshop Elements is an end-all, be-all, or that it might not be too advanced for some, but when one basically says, "all I need to do is resize my images, and I recommend that no one buy PS, or PSE," I cannot sit still. Might not be the right programs for that poster, but such negative blanket statements will not go by without a challenge, at least from me. I know that the MOD's are probably watching me closely there, as PS is not really about A camera, though can be closely related to the product from A camera.
Good luck,
Hunt
PS - Steve G. will probably banish me to the Video Lounge for dragging this thread OT, but that happens to me all the time. At least they removed that dusty plastic plant in the corner - the one that they always make me sit in, until I promise to be good.
