Mac mini thunderbolt port stop working

Good night.
First, I apologize for my English.
I have a mac mini (2011 model). Two days ago there was a power outage and the mac shut down. After turning it on, it failed to recognize my TV connected through the Thunderbolt port (with a adapter THUNDERBOLT -> HDMI).
When I disconnect and connect the adapter into the thunderbolt output, the screen flashes (as if he had recognized the second monitor). However, the monitor does not work.
Some Details:
1) In the monitor settings, only the main, connected by HDMI is detected;
2) On the "System Information" screen, the "Thunderbolt" item appears to state “no device connected";
3) I've done the reset PRAM / SMC.
Can anyone help me? Does my thunderbolt output fried?
Thank you,
Mateus.

I would try a different HDMI cable and then a different Thunderbolt/MiniDisplay Port to HDMI adapter.

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. WHen we plugged it into the port on the keyboard, the device works. Why?

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. When we plugged it into the port on the keyboard, the device works. Why? Obviously the device is operational. Could the USB port have burned out from having too much power drawn? If so, is it reparable?

It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.

Dell XPS 15 l502x mini-Display Port stopped working after update.

After the updates on the 11-10-2014 my mini-display port (which worked great previously and is part of the Intel Graphics) stopped working.
Am running Arch 64bit with Slim + E19
The symptoms are:
1. Detects monitor from the laptop and xrandr throws no errors
2. Enlightenment thinks the screen is connected and it appears in the screen setup as on.
3. The monitor no longer recognizes that there is a laptop plugged in and just stays off...

As far as I can see my options are to try and roll back via pacman -U in my /var/cache... or to figure out how to make my Nvidia HDMI output work using Synergy...
I suspect this is some type of driver regression (kernel/mesa/xorg) but am not sure as I have not seen much information about this issue online.
Unless someone has a better idea... when I get time to try to resolve the issue I will update this post.
Ok I missed this from dmesg:

So I downgraded those packages and the kernel with no luck.
I tried to get the HDMI working via Synergy... and failed
I then tested the Display Port on Windows and it did not work there either - exhibiting the same symptoms as Linux - the OS sees the monitor but no data was transferred.
So I ended up using one of my Display Link monitors at work... the USB monitors were ok, just an irritation with a flickering mouse.
I hope it is the miniDP>HDMI adapter and not the port... very frustrated by this problem.
I hope to test another adapter soon.
I think as nobody else is experiencing this issue that it may well be hardware/firmware related.
Hope there is a happy end to this post but not feeling so positive right now.

Mini DVI port stopped working

I often watch movies streaming on the internet by connecting my Macbook to my television via my Mini DVI to S-video adaptor cable. Last week, however, it suddenly stopped working. The television can still detect the display, but the image is super distorted and moving in a static-ey way. I can only vaguely make out the icons on my desktop on the TV screen.
I thought that perhaps my adaptor cable was at fault, so I bought a new one - but the problem remains. I have also tried resetting the PRAM, repairing the disc and permissions with Disc Utility, and cleaning the Mini DVI port. I am pretty certain that it is a hardware problem with the port itself.
One of the pins on my Mini DVI port looks like it could be out of place. It is kind of squished at the bottom of the port instead of laying flat like the others. I’m thinking that this might be the culprit. However, I have tried to straighten it out using a safety pin and I’m not really able to do it.
Am I right to assume this is a hardware problem with my port? Any advice about how I might go about fixing this? Is there a way to repair the port without having to replace the whole logic board?
The Macbook in question is a 2008 Core 2 Duo running Lion.
Any suggestions at all would be much appreciated!

I think you may be right, it's a hardware related MiniDisplay port connector problem.
I think you can't fix it up by replace MiniDispaly port connector, however fix it by replace whole logic board.

Mac mini Thunderbolt port

I'm the proud owner of a new Mac mini.
I'm also the proud owner of a pre-Thunderbolt Cinema Display, which works fine with the mini. However, I'd like to add another Cinema display so I will have dual monitors. As a result, I'm wondering if my current moniror will work in a dual-config with a new Thundrbolt display.
Thanks!

The first and most signifigant question is which Mini
do you have? If it is the Mini with the HD3000 graphics,
you can only use one of those displays, period.
If you have the one with the AMD graphics, it would support
two of the new TB displays but various threads across the net
seem to indicate that mixing the non-TB and TB displays can be
problematic.

Thunderbolt to Gigabit Ethernet Adapter or Thunderbolt port stopped working

Hey problem if anyone can help:
I use a Thunderbolt to Gigabit Ethernet Adapter, and all of a sudden it stopped working to connect to the internet on my Macbook Air (MacBook Air (11-inch, Early 2014 with OS X Yosemite 10.10.1 (14B25)). In my system information it says it is connected even when not, see below:
Thunderbolt to Gigabit Ethernet Adapter:
Vendor Name: Apple Inc.
Device Name: Thunderbolt to Gigabit Ethernet Adapter
Vendor ID: 0x1
Device ID: 0x8003
Device Revision: 0x1
UID: 0x0001000202DD0A30
Apple Serial Number: DTN4263048VDWKHBQ
Route String: 1
Firmware Version: 5.5
Port (Upstream):
Status: Device connected
Link Status: 0x2
Speed: Up to 10 Gb/s x1
Port Micro Firmware Version: 0.0.8
Can anyone help me figure out what the issue is? Is it the Adapter, the Thunderbolt port itself? A gremlin? Thanks!

Which model MacBook Pro do you have? Does it have a Thunderbolt port? If so the TB->Ethernet adapter MAY work (although it's specifically designed for those MacBook models that lack an Ethernet port).
The adapter would certainly be the cheapest way to go - if it works. Personally, I would rather have the Ethernet port on my MacBook Pro working, but this may be an expensive fix, I don't know. If I were you, I would at least take your computer to your local Apple Store/AASP and get a free diagnosis and estimate to repair your MBP. If it seems as if it's going to be too costly, then you may certainly try the adapter and see if it works.

FYI...what you are doing is condidered rude which I am sure is not your intent at all. It's called thread jacking. Just create a new thread and someone will be happy to help.

Mini dv port not working

When the mini dv port stops working, is there anything software wise that might resurrect it? This is on a refurb (from Apple) 2008 MBP, and the port was never actually used for anything until this past week, and it is not working. Could it be software related? Suggestions for repair? I've looked everywhere but it seems this is a very uncommon problem.

MAC PRO Internal USB ports stopped working

Hello, I have a mac pro 8 core with an USB internal ports problem, the 2 in front are not working anymore, and from the 3 in the back only the middle one is working.
I tried to pull all the power out for a whole night, resetting the pram and nvram but nothing helps.
When for example I put in a keyboard in one of the ports that is not working and when I power up the machine and I press the ALT key I get the choice of startup preferences, once I select one, and the system boots up the ports stops working, so before the OS loads the usb ports are working !!!
What to do ??

This is a hardware failure. While USB ports on the whole are just not designed very well, leading to their failures being pretty common, your issue sounds a bit more like the USB controller chip is failing.
In any case, the answer is to take it to a repair shop. If they're smart about it, they'll replace the logic board and see if that also fixes the front ports. If not, they'll replace the front I/O panel as well.

Dual Monitors on Mac Mini Late 2014 not working on Dell S2340Lc

Hey guys,
Got a mac mini and using it mainly for work. Working for an ISP and no one has used macs and I've opted to be the poor sucker that gets to deal with old people that don't know how to mac very goodly.
I have two Dell S2340Lc monitors. I have one connected up via HDMI and that works perfectly fine. I turned off the mac, I plugged in Monitor 2 with a MiniDP/Thunderbolt to HDMI adapter, powered on the mac and whilst it was booting, it had the Apple logo and the loading bar on the Dell display plugged in to the thunderbolt to hdmi adapter and then once it loaded up the log in screen, it went to the HDMI display. I logged in and in the displays section, the monitor plugged in to the thunderbolt to hdmi adapter isn't being detected, however I can plug it in to a Samsung 55 Inch Smart TV and it works just fine. I can set up dual monitors between the TV and the monitor in HDMI, but the Dell S2340Lc will only work with a HDMI cable into the HDMI port on the mac mini and will not work through the thunderbolt to hdmi adapter. On the display it just says that there is no signal coming from the computer.
Just wondering if any of you apple gurus had any ideas as to why this isn't working?
Thanks!

One usb port stopped working today

One of my USB ports stopped working today. I think it may be related to Itunes update today. Has anyone else seen this recently? I restarted my computer - but that didn't help. I have a MacBook Pro - running Lion 10.7.5
Any suggestions? I saw one USB Hub when I went to Apple --> About this Mac, but couldn't tell if both were there.

Hi，
So switch a LAN card fix this issue...seems a compatibility issue or maybe some packs or programs you installed recently cause this issue.
Have you manually check the network adapter driver from the PC's manufacture website? sometimes, it will be a time delay before Microsoft push out the driver update.
Check if issue exists in safemode with network, this mode will launch Windows with limited sets of files and drivers.
if you have a restore point, restore the pc to a previous point at which the pc is functioning fine.

MDB and Database - Listener port stops working

Hi,
I have created an MDB which does the following when a message is received from the queue.
1. Store message in database
2. do some processing
At step 1, if there is any issue with the database connection (e.g. database is not available etc), I rollback transaction. My idea is to leave the message on queue for now and retry it again after some time unless the database is back again. "Maximum retries" of the listener port is set to N but since there is no retry interval available, all N retries are done in a flash and my listener port stops working. I cannot use backout mechanism as I have to wait for the database to be back again. What are my options?
